The differentiating logic of Drydock (review scopes, findings/verdicts, the +guided tour, the MCP tool surface, agent session lifecycle) lives in UI-free packages +that compile against nothing but the JDK and can move almost as-is. The part that +would *not* port — the custom multi-repo window shell and the native Ghostty terminal — +is exactly the part IntelliJ already replaces with something better supported. +Rough sizing (inferred, not measured): an MVP with the review loop end-to-end is +~6–10 weeks of one engineer; full concept parity ~1 quarter. + +## 1. What Drydock actually is (inventory, proven from the code) + +342 Java files: ~50.5k LOC in UI/terminal/app/launcher/handoff packages, ~33.8k LOC in +everything else. The distinct concepts: + +| # | Concept | Where | +|---|---------|-------| +| 1 | Multi-repo workspace shell: sidebar of repos → session tabs, custom undecorated window, theming | `app.drydock.ui` | +| 2 | Embedded real terminal per session (Ghostty native on macOS, JediTermFX+ConPTY on Windows) running the real `claude` CLI | `app.drydock.terminal.*`, `docs/native-integration.md` | +| 3 | Agent provider SPI: create/resume/adopt conversations, launch plans, session-id strategies, activity watcher (busy/idle/attention states) | `app.drydock.agent.*`, `app.drydock.activity` | +| 4 | Review system: HMAC scope handles (`rs_…`), queue (MINE/AGENTS/REQUESTED/STACK), findings with threads/severity/proposed patches anchored to file+line keys, verdicts keyed by hunk digest | `app.drydock.review`, `docs/ui-redesign.md` | +| 5 | Guided review tour: steps, predict/trace/risk checks, grading gates, hunk verdicts derived from step progress, tour migration across a changed diff | `app.drydock.review.tour` | +| 6 | In-app MCP server + tool router (`review_scope`, `review_finding`, `review_tour`, `review_check`, `review_answer`, `review_state`, worktree/repo/session tools) with prompt-safety and budget guards | `app.drydock.mcp` (`McpToolRouter` 1,680 LOC, `McpServer` on `com.sun.net.httpserver`) | +| 7 | Worktree lifecycle: create sessions in worktrees, PR checkout (detached worktree + `gh pr checkout`), merge-and-finish flows | `app.drydock.git`, `app.drydock.ui` | +| 8 | Git/GitHub read layer: status, diffs with fixed context lines, `gh` review requests, clone | `app.drydock.git`, `app.drydock.github` | +| 9 | Symbol intelligence for review: tree-sitter grammars, Java/Kotlin tree walkers, out-of-diff fan-in, lexical usage tiers; a separate JDT LSP tier | `app.drydock.review` walkers, `app.drydock.lsp` | +| 10 | Persistence discipline: single-writer `ApplicationState`, per-store writers (`AnnotationStore`, `TourStore`), lenient cosmetic decoding | `app.drydock.state` | +| 11 | ProcessRunner discipline (all spawns: arg-list, timeouts, forced destroy) | `app.drydock.process` | +| 12 | Handoff files between sessions; remote SSH repos; MCP console/activity log | `app.drydock.handoff`, `app.drydock.ssh` | + +**Key structural fact (proven by grep):** packages `review`, `mcp`, `agent`, `git`, +`state`, `activity`, `github`, `domain`, `search`, `lsp`, `process`, `ssh`, `config` +contain **zero `javafx` imports**. The only `com.sun`/internal usages outside the +terminal host are `com.sun.net.httpserver` in `McpServer` — a JDK module, fully usable +from a plugin. The engine is already headless; JavaFX is a shell around it. + +## 2. What IntelliJ gives you instead (sources at the end) + +- **Terminal**: Reworked Terminal is default since 2025.2; a public plugin API landed + in 2025.3 (`TerminalView`, `TerminalShellIntegration`, block/command listeners, + `TerminalWidget.sendCommandToExecute/getText/isCommandRunning` for cross-engine + use). *Experimental, but exactly the surface Drydock needs: spawn `claude` in a tab, + watch it, send text.* The official Claude Code JetBrains plugin already runs + `claude` in the IDE terminal and adds selection/diagnostics sharing and native diff + viewing — so concepts 2+3 have a working precedent and a base to build on. +- **Git/VCS**: `GitRepository`, changes browser, diff/merge editors — Drydock's own + `git` package re-implements what git4idea provides natively. Native **git worktree + UI exists in IntelliJ 2026.1** (single-root projects; a Marketplace plugin covers + older versions). +- **Editors/diff**: line markers, gutter icons, range highlighters, inlays, editor + popups — the natural carriers for findings/verdicts/tour anchors (replaces + `ReviewFindingsMargin`, `ReviewDiffRows`, `TourMarks` wholesale). +- **PSI**: real syntax trees and find-usages for Java/Kotlin/etc. Strictly supersedes + the tree-sitter walkers + lexical usage tiers + the JDT LSP tier (which, per the + jdtls saga in the sphinx portability investigation, never worked well for Java on + cold repos). IntelliJ's own built-in MCP server exposes IDE-accurate + definition/callers to agents with zero startup cost. +- **Platform plumbing**: lazy tool windows, project/application `@Service` + singletons, `PersistentStateComponent` (maps the single-writer state discipline), + `PasswordSafe` for secrets, background task + threading model (maps the + "blocking work is async with progress indication" rule — IntelliJ *enforces* EDT + discipline), `ProcessHandler`/exec APIs (maps ProcessRunner), Plugin Verifier and + Marketplace distribution. + +**Not available (verified):** no public extension point to inject custom comments into +JetBrains' bundled GitHub PR review UI. A Drydock-style review layer must be its own +tool window + editor overlay — which is what Drydock already is, so nothing is lost. + +## 3. Concept-by-concept mapping + +| Drydock concept | IntelliJ port | Feasibility | +|---|---|---| +| 1 Multi-repo shell | Partially **against the grain**: one IDE project per window. Port as a "Drydock" tool window listing registered repos/worktrees/sessions (platform allows acting on arbitrary paths), or accept project-centric framing (project = repo). | Medium (paradigm friction, not API risk) | +| 2 Ghostty terminal | **Drop it** — use the built-in Reworked Terminal (public API 2025.3) or the official Claude Code plugin's terminal. Removes the entire native-host/FX risk surface that dominates `docs/architecture.md`. | High (simplification) | +| 3 Agent SPI + activity watcher | Ports nearly as-is: SPI is plain Java; the CLI hooks/transcript-watching logic has no UI dependency. Terminal tabs become `TerminalWidget` handles. | High | +| 4 Review scopes, findings, verdicts | Model code ports as-is (pure). UI re-expressed: findings → gutter/line markers + review tool window; verdicts → highlighters over the changes browser; scope handles unchanged (HMAC logic is self-contained). | High (model) / Medium (UI rework) | +| 5 Guided tour | Anchors map to editor ranges; checks become panels/dialogs in the diff view; `TourValidator`/`TourCodec`/grading ports as-is. This is Drydock's most differentiating feature and IntelliJ has no equivalent — nothing to fight. | Medium-high | +| 6 MCP server + tool router | `McpToolRouter`, `ReviewToolCodec`, `PromptSafety`, `McpSessionRegistry` are headless and reuse directly; `McpServer` (JDK HttpServer) runs inside the plugin. Sessions connect via `.mcp.json` written by the existing `McpConfigWriter`. Complement with IntelliJ's built-in IDE MCP server for definition/callers. | High | +| 7 Worktrees / PR checkout | `WorktreeService`/`PrCheckoutService` port as-is (ProcessRunner → platform exec is mechanical). UI rides the 2026.1 native worktree support. | High | +| 8 Git/GitHub layer | Either port as-is or shed in favor of git4idea + GitHub APIs; keeping the ported layer first minimizes risk, converging later. | High | +| 9 Symbol intelligence | **Replaced by PSI** — delete tree-sitter walkers, lexical tiers, LSP tier. Usage/fan-in becomes platform find-usages (accurate, warm). | High (net deletion) | +| 10 Persistence | `@State` services; keep per-store writers as plain classes if preferred. Lenient decoding policy preserved by implementing it in the `State` classes. | High | +| 11 ProcessRunner | Replace with platform exec APIs (same contract: arg-list, timeouts, forced destroy). | High | +| 12 Handoff / SSH remote / MCP console | Handoff: plain files + a small panel. SSH remote: IntelliJ Remote Development changes the model entirely — treat as out of scope for v1. MCP console: tool-window panel. | Medium / Low (SSH) / High | + +## 4. Risks and open questions + +- **Terminal API is experimental** (2025.3 public surface, under active development). + Pin to `TerminalWidget`'s engine-agnostic methods; expect churn. Mitigated by the + fact that Drydock's terminal needs are shallow (spawn, text-in/out, state). +- **Multi-repo in one window** is the biggest conceptual mismatch. Two viable shapes: + (a) a Drydock tool window that manages repos outside the current project — keeps + Drydock's mental model, fights the IDE less than it sounds because the IDE never + needs to open those repos; (b) project-per-repo + per-project sessions tool window — + more native, loses the "every repo in one pane" goal. *Needs a user decision.* +- **Cross-IDE compatibility**: review overlay UI should stick to platform-level editor + APIs (no Java-specific PSI in the core review path) so the plugin also runs in + PyCharm/GoLand/WebStorm. Drydock's tree walkers were already language-pluggable; PSI + keeps that via `LanguageExtension`. +- **Two review UIs**: users may have JetBrains' GitHub PR plugin review flow and ours + side by side. We cannot integrate into theirs (no EP); positioning must be explicit + (Drydock review = agent-interactive findings/tour layer, theirs = GitHub-native + reading). +- **Language**: IntelliJ ecosystem is Kotlin-first but Java plugins are fully + supported; the reused core is Java, so a Java plugin minimizes translation. + (Inferred; no evidence of friction either way.) +- **Reuse licensing/provenance**: the moved packages keep their history only if + extracted carefully (same-repo module split is the cheap route: make `app`'s core a + library module the plugin depends on, then decide extraction later). + +## 5. Suggested shape (for discussion, not decided) + +A single plugin `drydock-intellij`, Java, depending on Platform + bundled +`Git4Idea` + `org.jetbrains.plugins.terminal`: + +- **v0 (1 wk)**: plugin skeleton, settings, tool window scaffold, ProcessRunner→exec + adapter; core packages moved into a shared module, tests green on the plugin + toolchain. +- **v1 — sessions (2–3 wks)**: agent SPI active, `claude` tabs per repo/worktree in + the terminal, activity watcher → status dots, resume picker via + `ConversationSource`, worktree create/checkout actions. +- **v2 — review loop (3–5 wks)**: scope registry + queue tool window, findings as + editor overlays + threads panel, verdict bar as diff-viewer action, MCP server + + full `review_*` tool surface (largely reuse). This is the point where the port is + *useful*: an agent in the IDE terminal reads and answers human review comments + anchored in the real editor. +- **v3 — tour (2–3 wks)**: tour UI over diff viewers, checks, grading, MCP + `review_tour`/`review_check`. +- **later**: GitHub clone/PR queue polish, handoff, MCP console; SSH remote left out. + +What is intentionally **not** ported: Ghostty/AppKit host (superseded), the custom +window chrome/theming (superseded), SearchRail/Peek/navigation (superseded by IDE), +the JavaFX density/font-scale machinery (superseded). + +## 6.

Drydock contributes a node to the IDE's Services tool window, the way Docker, Databases and Run Dashboard do. The tree is app-level, so every window shows every repo › worktree › session. A session's console lives in the Services detail pane of the window that owns its worktree; in every other window the same node shows status and a Raise button.

+
+
+ Who owns what + Durable sessionServices node (app catalog) + Live processProcessHandler in the worktree Project + PresentationServices detail pane › Console tab + Windowone Project per worktree +
+
+
Fits — tree already models parent › child facts; group-by, speed search, multi-select and keyboard nav come free; console-in-detail is how Docker shows logs.
+
Strains — Services is a shared, often-hidden window; console beside a tree is cramped at the bottom anchor; Drydock competes with run configs for the top level.

Drydock tool window + Run console

+

The v3 direction, refined. A dedicated Drydock tool window (right) lists the app-wide catalog, with This window pinned on top. The agent runs as Run-tool-window content in its worktree's window, owned by Drydock's execution service, so there's no native Rerun and no persisted run configuration. Review is the tool window's second tab.

+

+
+
Fits — Phase 0 already proved the Run-console path for all three agents; one branded place to look; Run already means "a process that starts, stops and exits".
+
Strains — two tool windows for one concept; agent tabs sit beside the user's own run configs; right list + bottom console use up both edges.

Window-centric

+

A worktree window is the session. The agent console opens as a pinned editor tab, first in the tab row, so it can split beside the code it is editing. There's no Drydock tool window. The catalog lives where the IDE already lists projects: the title-bar Project widget, a status-bar widget and Recent Projects. Review is a tab in the Commit tool window.

+
+
+ Who owns what + Durable sessionProject widget / Recent Projects entry + Live processProcessHandler in the worktree Project + Presentationeditor tab (restorable virtual file) + Windowone Project per worktree, titled by session +
+
+
Fits — Project = folder = window is the IDE's own fact model; editor tabs already persist and restore, and closing one hides it rather than deleting it; the agent stays centre stage.
+
Strains — a terminal hosted in an editor tab is less proven than Run; the catalog sits in popups, so it's harder to see at a glance; lots of windows on a laptop screen.

Hybrid: Services + Terminal + Commit view

+

The catalog lives in Services, as in A, but the detail pane is a summary card, not a console. The agent shows up where CLI users expect it, a Terminal tab. The tab is only a view: the process runs in a detached host (the existing tmux persistence), so closing the tab detaches it. Review decorates the Commit tool window's own Changes tree.

+
+
+ Who owns what + Durable sessionServices node (app catalog) + Live processdetached host (tmux) — outlives the IDE + PresentationTerminal tab attached to it; close = detach + Windowone Project per worktree +
+
+
Fits — Terminal is where people already run claude/codex; agents keep working through IDE restarts; review happens in the view people already commit from.
+
Strains — Terminal-tab lifecycle is where v2 broke, so this only works if the tab owns nothing; tmux means no Windows; it reverses v3's "project close stops execution", which needs a decision.

Drydock in IntelliJ: where do sessions live?

+

v2 broke because one object stood for four different things: the durable session, the live agent process, its presentation (a Terminal tab) and the window (a Project). The four directions below keep those separate, and each gives them a different home in the IDE. All share a set of fixed rules, listed at the bottom.

  • Right-anchored Drydock tool window; toolbar = New Session · Resume Conversation · New Worktree · Check out branch in worktree.
    • +
  • The list is scoped to this project's repository, so there's no multi-repo view.
    • +
  • Sessions live as Terminal tool window tabs; closing a tab changed session status. That's the conflation behind the v2 bugs (restored tabs, idle sessions removed on restart).
    • +
  • A worktree row disappears once it has a session, so the same thing shows up in two different ways.

Fixed in every direction

+
    +
  • One IDE window per worktree. The catalog is app-level and visible from every window.
    • +
  • Clicking a session that lives elsewhere raises that window. Nothing is proxied.
    • +
  • IDE or Project open starts nothing. Resume starts exactly one execution.
    • +
  • Only Forget removes a row. Removing a worktree is a separate step that warns about data loss.
    • +
  • Stop is Drydock's own action (non-soft, then force-kill). There's no native Rerun.
    • +
  • Rows are labelled by the agent-given title. Agent and branch are secondary.
    • +
  • "Needs you" shows as a stripe badge, a balloon and a window-title marker.
    • +
+
+
+

Decisions these surface

+
    +
  1. Should an agent keep working when its window, or the IDE, closes? D says yes; A, B and C say no.
    2. +
  2. Branded surface (B) or IDE-native surfaces (A, C, D)?
    3. +
  3. Where is the console most comfortable for long sessions: bottom panel (A, B, D) or editor (C)?
    4. +
  4. Is the guided tour worth its own review tab (A, B, C), or is a decorated Changes view enough (D)?

Adversarial review of E for MVP

+

An IntelliJ-UX reviewer's pass over E, looking for what breaks under real use. It was written by the same model that drew E, so treat it as a checklist, not an independent sign-off. Each item has the frames it affects, the failure, and a proposed fix. Items marked DECIDE need your call.

+
+ +
+

High: likely to hurt in week one

+ +
+
H1 · Keystrokes the agent needs get eaten by the IDEE1, E4, E9
+ Agent TUIs live on Esc (interrupt), Shift+Tab (mode), ⌃C, ⌃R and arrow history. In an editor tab, the IDE keymap and editor actions see those keys first. A swallowed Esc means the user can't stop a runaway agent from the place they're looking at it. My own ⌃⇧A / ⌃⇧R shortcuts add more conflicts. + Fix: add a pass-through key list to the Phase 0 editor spike as a pass/fail gate, test it with all three agents, and give Drydock shortcuts only actions that don't fire while the agent tab has focus. +
+ +
+
H2 · ⌘Q silently kills every working agentDECIDED · confirmE6
+ "Window close stops, no prompt" was set for one window. Quitting the IDE closes all of them, and an agent mid-edit or mid-test leaves a half-applied change. A balloon afterwards doesn't undo that. + Fix: keep "no prompt" for idle and at-prompt agents. Confirm only when ≥1 agent is working: "Stop 2 working agents?" with Stop / Cancel / Don't ask again. That's one dialog in the rare dangerous case. +
+ +
+
H3 · Committing from the wrong scopeDECIDED · proposalR2, E7
+ R2 reuses the Commit view, where checkboxes mean "include in commit". In "branch vs main" scope the tree lists files that are already committed, still next to checkboxes and a Commit button. Users will read it as "commit these 4 files". + Fix: in branch scope, hide the checkboxes and swap Commit for Finish ▾. Show a one-line hint ("Reviewing 3 commits + 1 uncommitted file vs main") so the scope is always named. Uncommitted files keep a ● marker. +
+ +
+
H4 · A new window is slow before it's usefulE3
+ Each worktree is a new Project: Gradle/Maven import and indexing on a fresh copy of dd-trace-java takes minutes and memory. If the agent waits for the window to be "ready", the main promise (start a task fast) breaks. If it doesn't, the user sees a red, half-indexed project. + Fix: start the agent as soon as the frame exists, and say so in the strip ("Working · IDE still indexing"). Offer shared indexes and "skip build import" in the New Agent Worktree dialog. Measure on dd-trace-java before MVP. +
+ +
+
H5 · You and the agent editing the same fileE4, E10
+ The split-editor story (E4) invites typing in the file the agent is changing. Unsaved buffer vs on-disk write gives you IntelliJ's "file changed on disk" conflict, or silently lost keystrokes. "Writes + Here" on the main checkout makes it a daily event. + Fix: while an agent is working, mark the files it has touched this turn as read-only in the editor (a soft lock with an "Edit anyway" banner), and flush unsaved buffers before each agent turn. Keep "Writes + Here" behind Start anyway (already in E10). +
+
+ +
+

Medium: friction and confusion

+ +
+
+ M1 · Four places list the same sessions + Agents ▾, the status-bar widget, the Services node and the Welcome tab all show the same catalog. Each needs its own state syncing and its own bugs. The status widget mostly repeats the Agents ▾ counts. + Fix: MVP ships Agents ▾ + Welcome tab only. Status widget and Services node come later, and only if users ask. +
+
+ M2 · Window titles that rename themselves + Agent-given titles arrive late and change, and two sessions can get near-identical titles. A window whose name shifts under ⌘` is hard to find again. + Fix: window = repo · branch (stable, unique). The agent title lives on the tab and in Agents ▾ rows, where change is expected. +
+
+ M3 · Attention you miss when the IDE isn't in front + Balloons and badges only show in the focused IDE. With the browser in front, "needs you" can sit unnoticed for 20 minutes. With 4 agents in the IDE, balloons stack up. + Fix: use the IDE's own system notification when the app is inactive, as it does for long builds. Collapse simultaneous balloons into one ("2 agents need you"). +
+
+ M4 · Merge into main touches your own checkout + "Merge into main" runs in the main checkout, which may be dirty, on another branch, or open in a window you're editing. + Fix: a pre-flight in the Finish menu ("main checkout has 2 uncommitted files: stash / cancel"), never a silent branch switch. Disable it with a reason when main isn't on the target branch. +
+
+ M5 · Too many verbs that end a session + Close tab, Stop, close window, Forget, Remove Worktree… Each does something different, and users won't keep them apart. + Fix: a single "Done with this…" action that offers the combinations (as in B7), plus a tooltip on tab close: "Agent keeps running · ⌃⇧A to reopen". +
+
+ M6 · Resume has a cost nobody sees + Resuming a long conversation re-sends its context. The core already has ResumeCostEstimate, but E6's Resume button doesn't show it. + Fix: show the estimate on the Resume button ("Resume · ~180k tokens"), and offer "Resume with summary" when the estimate is large. +
+
+ M7 · The tour holds up the MVP + T1 and T2 are both large and undecided. Shipping R2 with findings already covers "review the agent's diff". + Fix: cut the tour from MVP. Run the T2 diff-viewer extension spike alongside, and decide T1/T2 from its result. +
+
+
+ +
+

Low

+
    +
  • Colour-only status. Blue vs amber dots are weak for colour-blind users. Pair them with shape (● working, ◐ needs you, ○ idle), as the title marker already does.
    • +
  • RO overstates safety. Even enforced read-only agents can run shell commands. Strip copy: "can't edit files" → "won't edit files (plan mode)".
    • +
  • Raising windows across macOS Spaces jumps the whole desktop when a worktree window is full-screen elsewhere. Raise should show which window it's going to.
    • +
  • Title-bar marker (E5 ③) needs internal API and is rarely visible in the New UI on macOS. Drop it from MVP.

Synthesis: agent in the editor

+

Built from your four answers. It uses the window model and editor-tab console from C and only IDE-native surfaces for the catalog: an Agents ▾ title-bar widget next to the Project widget, a status-bar widget, and an optional Services node from A. Closing a window stops the agent; there's no detach in v1. Review decorates the stock Local Changes view, as in D. Three density levels are shown so you can judge how crowded it gets.

A window is still one worktree, but it can hold several agent tabs. A read-only session is the usual second one: ask questions, explore, plan, without creating a worktree. Sessions are created in a mode, Writes or Read-only, and the mode shows on the tab. Rule: at most one writing session per worktree by default; a second one needs an explicit override.

  1. Every session is its own pinned agent tab with its own dot and title. Read-only tabs carry an RO chip so a glance tells you which one can touch files.
    2. +
  2. The strip names the mode and how it's enforced (Claude plan mode, Codex read-only sandbox). If an agent has no enforced mode, the strip says "not enforced" instead of implying safety.
    3. +
  3. The window title uses the writing session's title, plus a "+1" count.

  1. A worktree with more than one session gets a ⑂ header row with its sessions beneath. Clicking a session raises the window and selects that agent tab. The main checkout appears as an ordinary worktree with read-only sessions.
    2. +
  2. A worktree with one session stays a single flat row, as in E2, so the common case doesn't get deeper.
    3. +
+
+ +
+
    +
  • Closing the window stops every session in it. The E6 balloon lists them, and "Reopen & resume" restores all of them.
    • +
  • Attention names the session, not just the window. Raise selects the waiting tab.
    • +
  • Review / Finish covers the worktree's diff; read-only sessions add nothing to it. Finish on a worktree that has read-only sessions stops them too.
    • +
  • Promote: a read-only session can't change mode in place, because that needs a restart with new flags. "Continue as writing session…" resumes the same conversation in Writes mode, here or in a new worktree.

  1. A Drydock Agents ▾ widget sits right after the stock Project widget, in the title bar's left toolbar area (public action groups). Its popup is the quick list: every repo and session, whatever window you're in (the catalog is app-level, not scoped to this project), each row a window, searchable. The counts on the widget make it a status light too.
    2. +
  2. Optional Services node for a list that stays open (triage, group by status). Its detail pane is a status card only; the console stays in the editor.

  • + The tour becomes a grouping, so it needs no extra panel. Toggle it off and you're back at R1/R2.
    • +
  • − Tour checks (predict / trace) still need a home, maybe an inlay in the diff. A file in two steps shows twice.
    • +
+
+ +
+

Decision: R2. Findings are child nodes under their file, and resolved ones are hidden by default. Tour steps are not in the Changes tree; the tour gets its own editor (T1 / T2, below). R1 and R3 are kept for reference.

+
+ +
+
+
NEW

The guided tour gets its own editor

+

A step is a logical change: narrative, anchored line ranges with notes, impact, checks that gate it, and an optional staged diagram. A file can belong to several steps, so the tour can't be a grouping of the Changes tree. Both options open the tour as an editor tab next to the agent, reached from the agent strip's Review link or the Changes header. They differ in who renders the code.

  2. The centre stacks only this step's ranges, file by file, as read-only IDE editors over a display-only full-context diff document. Other steps' changes in the same file show faintly, tagged "step 3". Drydock controls hiding, so PREDICT can hide added rows exactly as the app does.

  1. The tour drives the IDE's own diff viewer: a step bar on top and a step panel attached on the right. The outline collapses into the "Step 2 / 5 ▾" dropdown. A step spanning files walks its ranges in order; "Next range" can switch to the next file.
    2. +
  2. Anchored ranges get a strong left bar, notes become inlay callouts under the range, other steps' rows are faint with a "step 3 ›" inlay, and findings use the existing gutter ◆.
    3. +
  3. The same step panel content as T1. Hiding added rows for PREDICT has to be done by folding them inside the diff viewer, which is less certain than T1's own document.
    4. +
+
+
+
+
Shared by both + • Same file in several steps: the outline lists the files per step ("SessionDots ×2"); in the code, other steps' changes are faint and tagged with their step number. + • R2's Changes tree gets one more secondary label per file, its steps: "SessionDots.java · steps 1 2 3". + • Peek, trail and search come from the IDE: ⌘-click, Quick Definition, Back/Forward, Find in Files. The app's own copies aren't ported. + • Step states (passed, overridden, stale) and the coverage footer are the same as in the app. +
+
Trade-off + T1 keeps every tour rule as specified (hidden added rows, receding claims), and the app's display-only diff carries over. You build and maintain one more viewer. + T2 feels most native and reuses the diff viewer users know. It depends on how far the diff viewer can be extended for the step panel, folding added rows and inlays. That needs a spike before committing. +

Editor tab events + are presentation only: closing a console tab hides it and the agent keeps + running. + +A terminated process persists `EXITED` (it ended on its own) or `INACTIVE` +(Drydock stopped it) and **never removes a row**. Only an explicit Forget +does. + +The console lives behind a registered `drydock-agent` virtual-file protocol so +the *platform* restores pinned console tabs; a `LightVirtualFile` has no +restorable URL, which would force the plugin to reopen tabs itself and race the +platform — the exact failure the v2 runtime had. + +--- + +## Deliberate deviations from the handoff + +Each of these is a place the handoff's text was not followed, with the reason. +They are candidates for reversal if the reason does not hold. + +1. **Agent and Mode are radio groups, not segmented chips** (surface 3). The + platform's segmented control is Kotlin-UI-DSL-only and unreachable from + Java. A radio group is the IDE's own rendering of an exclusive choice, + focusable and arrow-navigable; only the pill shape is missing. +2. **The task placeholder is a hint label above the field**, not greyed text + inside it. `JTextArea` has no `emptyText`, and faking one with a focus + listener is worse than a label that is always true. +3. **A fifth status word, `Running`.** The handoff's table gives four words and + maps them to RUNNING joined with BUSY / IDLE / NEEDS_ATTENTION. It names no + word for RUNNING with *unreadable* activity — which is most live sessions, + since only Claude ships an activity reporter. Both `Working` and + `At prompt` would assert something unknown, so `SessionDots` answers + `Running`. **Needs a designer's confirmation.** +4. **`Read-only · not enforced` for pi** (surface 2's chip). pi's CLI has no + read-only mode at all — see below — so the chip reports the mode as the + statement of intent it is, rather than a guarantee pi cannot keep. +5. **`Start` instead of `Resume`** when a stopped session has no recorded + conversation. The handoff shows `Resume · ~Nk tokens` unconditionally, but + with nothing to resume into that button can only reach the provider's own + session picker. `Start` runs the provider's create command on the same row. +6. **`IDE still indexing` only while an agent is running.** The note explains + "the agent started before the IDE was ready"; on a stopped session it + explains nothing, and under the words "Not running" it reads as the reason + the agent is not running. +7. **New Agent Session is ⌃⌥N on macOS, not ⌥⌘N.** In the macOS keymap ⌥⌘N + is Refactor | Inline in an editor and Git's New Branch elsewhere; pressing + it in `runIde` opened Create New Branch. The `$default` binding + `alt meta N` is translated by the macOS keymaps to ⌃⌥N, which opens the + dialog with no conflict. Windows/Linux (Alt+Meta+N) not tried. **Needs a + designer's confirmation.** +8. **Codex does not receive the dialog's task** (surface 3). Claude and pi + get it as their positional prompt, read off their `--help`; the installed + `codex` answered neither `--help` nor `--version` on the verification + host, so its prompt argument was not added unverified. +9. **"Forget + remove worktree" keeps the branch, and says so** (surface 9: + `Closes this window. The branch stays.`). The handoff only removes the + worktree; `git branch -D` would destroy unmerged commits. + Removal is offered only for this window's own linked worktree with no + other session in it; otherwise it is shown disabled with the reason. +10. **The close confirmation counts unreadable activity as working** + (surface 6). The handoff asks for busy or needs-you agents; Codex, pi, + and Claude before its first hook have no readable activity, and are not + known to be at their prompt. +11. **Claude's idle reminder is "needs you" until seen.** The shared hook + maps `idle_prompt` and `permission_prompt` to the same state, so a + Claude session turns amber about a minute after a turn ends. The + plugin now acknowledges the state as soon as the user is looking at the + session (tab selected in the active window, or Raise window / Snooze), + which is what makes surfaces 4 and 6 behave; distinguishing the two + notification types would need a new state word in the shared hook. + +--- + +## Read-only enforcement is uneven, by necessity + +`SessionMode` (WRITES | READ_ONLY) is persisted on every session and travels +into both launch contexts. Enforcement is the CLI's, and each flag was read +off the installed binary's `--help` rather than assumed: + +| Agent | Flag | Enforced | +|---|---|---| +| Claude | `--permission-mode plan` | yes, when the installed build advertises both the flag and the `plan` choice | +| Codex | `--sandbox read-only` | yes, unconditionally | +| pi | — | **no.** `pi --help` offers only tool allow/deny lists; enumerating edit tools here would rot the moment pi adds one | + +`AgentProvider.enforcesReadOnly()` is what lets the UI say "not enforced" +instead of showing a guarantee the agent cannot keep. + +--- + +## How this is verified + +- **Automated**, from `intellij-plugin/`: + `./gradlew test buildPlugin verifyPlugin`. As of the capture pass: + `test buildPlugin` green (1774 tests, 0 failures), every commit of the + pass compiling on its own.

This handoff covers the MVP of the IntelliJ plugin (`intellij-plugin/`). Its UX model is the result of the design exploration in this bundle: + +- **One IDE window (Project) per worktree.** A window holds 1…n agent sessions; usually one writing session, plus optional read-only ones. +- **The agent console is a pinned editor tab** in that window, not a Terminal or Run tool-window tab. +- **The session catalog is app-level** and shown through IDE-native surfaces: an **Agents ▾** widget in the main toolbar (every window) and an **Agents** tab on the Welcome screen (no window open). +- **Window close stops the agent**; the session stays as an idle row. Only explicit Forget removes a row. Nothing auto-starts. +- **Review happens in the Commit tool window** (branch-vs-main scope, findings as child nodes) plus the IDE diff viewer with gutter findings. **Finish** = merge locally or push + PR. + +This replaces the v2 Terminal-tab runtime, whose failure is described in `notes/drydock-intellij-mvp-wrapup.md`. The v3 ownership split (durable catalog, then project execution service, then ProcessHandler) still holds; only the presentation moves from Run content to an editor. + +## About the design files +The `.dc.html` files in this bundle are **design references built in HTML**. They show the intended structure, copy and behaviour; they are not code to port. Implement the surfaces in Swing/IntelliJ Platform UI (Kotlin UI DSL / JB components) inside `intellij-plugin/`, using platform components and LaF colours, so the result looks native in any theme. + +Open `Drydock MVP.dc.html` in a browser for the clickable prototype. Its scenario bar simulates "agent needs you", window close, IDE restart and the Welcome screen. + +## Fidelity +- **Drydock-owned surfaces are high-fidelity for structure, copy and behaviour.** These are the Agents widget and popup, the agent editor strip, the dialogs, the balloon, review rows and finding cards. +- **Visual styling must come from the IDE**, not the hex values in the prototype. The host IDE chrome in the prototype (title bar, stripes, tabs, Commit view) is a neutral approximation. Use JBColor / `JBUI.CurrentTheme.*`, standard paddings (`JBUI.Borders`), `ActionButton` / `ComboBoxAction` / `JBPopup`, and `DialogWrapper`. +- **The only Drydock-specific colours** are the status-dot palette already defined in `SessionDots.java` (see Tokens). + +--- + +## Phase 0: gating spikes (do these first; each has a pass/fail) +The build does not start until S1 passes. The other spikes decide between a primary and a fallback path. + +| # | Spike | Pass when | If it fails | +|---|---|---|---| +| **S1** | Agent console in a `FileEditor`: a custom `FileEditorProvider` for a Drydock `LightVirtualFile`, whose component hosts the `TerminalExecutionConsole` already proven in Phase 0A (`PtyCommandLine → KillableProcessHandler → TerminalExecutionConsole`). | All three agents (Claude, Codex, pi) render their TUI correctly. **Keys reach the agent while the tab is focused**: Esc, Shift+Tab, ⌃C, ⌃R, ⌃D, arrows, ⌥/Alt+arrows, Tab, Enter, Backspace, paste. Splitting and pinning the tab works. Reopening the project restores the tab **without** starting a process. Explicit Stop (non-soft, force-kill after 2 s) ends the process exactly once. | Fall back to Run-tool-window content (Phase 0B path) with the same strip as its toolbar. Everything else in this README stays. | +| **S2** | Worktree window time-to-useful on `dd-trace-java`: create worktree, open the Project, start the agent. | The agent starts within 2 s of the frame appearing, **not** waiting for indexing or build import. Measure and record the times to frame, agent start, and smart mode. | Keep agent start independent of indexing regardless; add "skip build import" to the dialog. | +| **S3** | IDE-native catalog surfaces: (a) an action/widget in the main toolbar placed after the Project widget (verify group ids in 2025.3, e.g. `MainToolbarLeft`); (b) a Welcome-screen tab (verify a public EP such as `welcomeTabFactory`). | Both use public API only. Plugin Verifier reports no internal API usage. | (a) Fall back to the `MainToolbarRight` area. (b) Fall back to a "New Agent Worktree…" action on the Welcome screen's Projects list. | +| **S4** | Review in the Commit tool window: can Drydock show **branch-vs-main** scope with findings as child nodes and **without commit checkboxes** in the stock Changes view? | Yes via a public extension. | Add a Drydock **Review** content tab in the Commit tool window built on `ChangesBrowserBase` (it looks native, and Drydock owns the checkboxes). This is the expected outcome; plan for it. | + +Also check before relying on them: `ProjectCloseHandler` (or equivalent) to veto/confirm a project close, `AppLifecycleListener` / `ApplicationListener#canExitApplication` for quit, `SystemNotifications` for OS notifications, and `DiffExtension` for decorating the diff viewer. + +--- + +## Ownership model (unchanged from v3, presentation updated) +- **Application:** durable session catalog (single writer, existing `ApplicationStateStore`), plus change notifications. +- **Project (= worktree window):** execution service mapping `ManagedSessionId → (ProcessHandler, agent FileEditor)`. A project can hold several. +- **Platform:** `ProcessHandler` events are authoritative for live state. Editor tab events are **presentation only**: + - Closing the agent tab hides it; the process keeps running. Reopen it with ⌃⇧A or from Agents ▾. + - Closing the Project stops every execution in it (confirmation rules below), and the rows go idle. + - Quitting the IDE does the same for all projects. + - Opening the IDE or a Project starts nothing. +- **Remove from runtime** (per wrap-up notes): `TerminalSessionLauncher`, `SessionTabRegistry`, `TerminalTabGuard`, restored-tab sweeps, terminal content lifecycle monitor, tab-close-as-status-transition. The existing `SessionsPanel` tool window is **replaced** by Agents ▾; don't ship both. + +## Status vocabulary +Map from existing `SessionStatus` + `SessionActivity` (keep `SessionDots` as the single mapping): + +| UI word | Dot | Source | +|---|---|---| +| Working | filled blue | RUNNING + BUSY | +| At prompt | filled blue | RUNNING + IDLE | +| Needs you | filled amber | RUNNING + NEEDS_ATTENTION | +| Not running | hollow grey ring | INACTIVE / EXITED | +| Failed / Missing directory / Unsupported agent | filled red | existing ERROR facet words | + +Dots are static, with no animation (see `notes/status-dot-pulse-cpu-wrapup.md`). + +--- + +## Screens / views + +### 1. Agents ▾ widget (main toolbar, every window) +- **Placement:** directly after the stock Project widget and branch widget. +- **Default:** blue dot + count of non-idle sessions + "Agents" + chevron. Copy: `5 Agents`. +- **Any session needs you:** amber dot + `1 waiting · Agents`, with a warning-tinted background (use the theme's warning/notification colours). +- **Click** opens a `JBPopup` (≈440 px wide, max ≈420 px list height) anchored under the widget: + - **Search field** (focused): `Search sessions`. Filters by title and branch. + - **List**, grouped by repository (header row: repo name, small semibold secondary text). + - A worktree with **>1 session** gets a sub-header `⑂ ` (with `this window` right-aligned if current), and its sessions are indented 18 px. + - A worktree with **1 session** is a single flat row: dot · title · [RO chip] · right-aligned ` · ` (or `this window`). + - **Row click:** raise or open that worktree's window **and select that session's agent tab**. If the window isn't open, open it without starting the agent. + - **Footer row:** `＋ New Agent Session…` with shortcut `⌥⌘N`. +- **Order:** this repo first, then the others alphabetically. Within a repo, Needs you sorts first. + +### 2. Agent editor tab +- **Tab:** status dot + agent-given session title (+ `RO` chip for read-only). Pinned, first in the tab row. Each session in the window has its own tab. +- **Strip** (≈36 px, editor-notification-panel style, full width above the console): + - left: dot · bold state word (`Working` / `At prompt` / `Needs you` / `Not running`) · for RO, a bordered chip `Read-only · won't edit files` · secondary ` · · files changed`. + - right (running): link `Changes` (opens the Commit tool window review) · button `■ Stop`. + - right (not running): primary button `Resume · ~k tokens` (from `ResumeCostEstimate`). + - right (always): `⋯` opens "Done with this session…" (screen 9). +- **Console body:** the terminal, edge to edge, editor font. + - Not running: the last transcript dimmed (50 %) with a footer line `— stopped · nothing restarts on its own —`. + - File paths in output are hyperlinks that open in the adjacent editor split. +- **Window title:** ` · ` (stable). The agent title appears on the tab and in Agents ▾ only. + +### 3. New Agent Session dialog (`DialogWrapper`, ≈520 px) +Fields: +- **Task:** multiline, placeholder `What should the agent do?` +- **Agent:** segmented chips `Claude` `Codex` `pi` +- **Mode:** segmented `Writes` | `Read-only` +- **Where:** radios + - `Here` with ` / ` + - `New worktree` with `⑂ from main`. The slug is the first 3 words of the task; the branch name stays editable. The base is the repo's **default** branch. + +Defaults: +- Writes → New worktree. +- Read-only → Here. + +Warnings (inline warning-tinted box) for Writes + Here: +- If another writing session is active in this worktree: `Another writing session is active in this worktree. Two writers can overwrite each other.` +- Otherwise: `A writing agent here shares the tree with your own edits.` + +The primary button then reads `Start anyway`. Otherwise it reads `Create & Open Window` (new worktree) or `Start Here`. + +On create: +1. Create the worktree (existing `WorktreeService`). +2. Open its Project. +3. Open the agent tab. +4. Start one execution **immediately** (don't wait for indexing). Strip secondary text: `IDE still indexing` while the project is in dumb mode. + +Read-only enforcement is per provider: Claude plan mode, the Codex read-only sandbox, and nothing for pi (strip copy then says `not enforced`). Verify the flags in the provider SPI. + +### 4. Attention ("needs you") +On a transition into NEEDS_ATTENTION: +- the Agents ▾ widget turns amber (every window), and the agent tab dot turns amber; +- one balloon in the focused window. Title ` needs you`, body ` · ` plus the prompt summary, actions `Raise window` · `Snooze`. If several arrive at once, collapse them into one: `2 agents need you`; +- if the IDE is not the active app, an OS notification via the platform's system notifications. + +The answer is always given in the agent tab; Drydock never proxies it. There's no title-bar marker in the MVP. + +### 5. Resume and idle state +- After restart or window close, every session row is idle and its tab restores in Not running state. Nothing starts. +- `Resume · ~Nk tokens` starts exactly one execution of the provider's resume command (by id; never `--continue`/`--last`). + +### 6. Close / quit confirmation +- **Closing a worktree window:** if ≥1 session in it is **Working** (busy or needs-you), show a `DialogWrapper`: + - title `Stop working agent(s)?` + - body `Closing · stops them mid-task.`, then a list of `● · <Agent>`, then secondary `Agents waiting at the prompt are stopped without asking.` + - checkbox `Don't ask again`; buttons `Cancel` · `Stop & Close` (default). +- Otherwise close silently. +- **Quitting the IDE:** one dialog listing working agents across all windows, with the same copy and buttons (`Stop & Quit`). + +### 7. Review in the Commit tool window +Expected: a Drydock **Review** content tab (S4 fallback); it may be the stock view if S4 passes. + +- **Header:** + - `Scope Branch vs main ▾` with `<k> / <n> reviewed` right-aligned; + - hint line `<c> commits + <u> uncommitted file(s) vs main`. +- **Tree:** `▾ <branch> vs main · <n> files`. + - **File rows:** file-type icon · name · `●` (blue) if uncommitted · secondary path · right mark: `✓` (reviewed, green), `◆ n` (open findings, amber), `○` (unreviewed, muted). + - A file with open findings expands to **finding child rows**: severity chip (`MED`, amber) · finding title · `:line`. **Resolved and dismissed findings are hidden** (footer `n resolved findings hidden`). + - Click a file → IDE diff (unified, full context) for branch vs main. Click a finding → the same diff scrolled to the line. +- **Branch scope has no checkboxes.** The bottom keeps the commit-panel shape: + - the agent-drafted message (`Drafted by <Agent> · edit freely`), then `No checkboxes in branch scope` and a primary `Finish ▾`; + - no Commit button in this scope. +- **Diff decoration** (via a diff-viewer extension): + - gutter `◆` on finding lines; + - block inlay card under the line (warning-tinted, max ≈640 px): severity chip, title, body, and status (`Proposed by <Agent>` / `Confirmed`); + - actions on a proposed finding: `Confirm` (primary) · `Dismiss…` (asks for a one-line reason, which is appended to the thread) · `Not sure · ask <Agent>`; + - action on a confirmed finding: `Ask <Agent> to fix` (sends it to the agent tab). +- **Diff header actions:** `Mark file reviewed` / `Reviewed ✓`, plus the change counter `1 of 2 changes`. + +### 8. Finish ▾ menu +- `Merge into main`: secondary `Commit, merge in the main checkout, close this window`, plus a pre-flight line: + - green `✓ main checkout is clean and on main`, or + - disabled with the reason (dirty / not on main / not found). +- `Push & create pull request…`: secondary `Commit, push, open a PR; the window stays for review rounds`. Uses `gh`. +- Checkbox `Remove worktree after merge` (default on). +- Warning line if any finding is open: `1 open finding.

Worktree and branch stay.` +- `Forget + remove worktree`, with secondary `Closes this window. <n> uncommitted file(s) will be discarded.` The data-loss text appears only when the tree is dirty. + +Footer: `The agent's own conversation history on disk is kept either way.` Buttons: `Cancel` · `Forget` / `Forget & Remove`. + +### 10. Welcome screen: Agents tab +- Next to Projects; the label shows the count. +- **Toolbar:** search `Search sessions`, plus primary `New Agent Worktree…`. +- **List** grouped by repo. Row: dot · title · RO chip · secondary `<Agent> · <branch> · <age>` · `Open` · `Resume` (Resume only when the session is not running). +- Footer: `Nothing runs without a window.

Steps use checkbox (`- [ ]`) syntax for tracking. + +**Goal:** Replace the plugin's Tools-menu entry points with a task-centric +Drydock tool window over a registered-projects list shared with the +standalone app, with a New task dialog and loss-aware stop/cleanup. + +**Architecture:** Part A adds a small cross-process store, +`~/.drydock/projects.json`, to the headless core of both trees. The app's +`RepositoryManager` then takes its membership from it. Part B builds the +plugin side: +- seeding the shared list and polling it for changes; +- a pure `TaskTreeModel` behind a Swing tool window; +- a `NewTaskDialog` and `TaskLauncher`; +- stop, cleanup and remove flows that reuse the existing confirmation + pieces. + +Each tool keeps its `state.json` `repositories` list as a **local mirror**, +keyed by the shared id, holding per-tool settings (`lastUsedAgent`). The +visible membership is the shared list. So `ApplicationStateCodec` does not +change. This refines the spec's "codec dropping `repositories`" note: same +behaviour, less churn. + +The plugin keeps its R7 per-worktree repository ids for sessions. The tree +places a session by resolving its working directory to a canonical **main +checkout** with `git worktree list`, never by repository id. That is what +makes "adding a project again brings its sessions back" work with no +migration. + +**Tech Stack:** Java 21 (plugin core floor JBR-21), JUnit 5, IntelliJ +Platform 2025.3.3 (IPGP 2.19.0), Swing / IntelliJ UI DSL-free components +(`Tree`, `SearchTextField`, `ActionToolbar`, `DialogWrapper`), JavaFX in the +app (untouched UI except the change listener). + +**Spec:** `docs/superpowers/specs/2026-10-19-intellij-task-tool-window-design.md` + +## Global Constraints + +- Shared file: `~/.drydock/projects.json`; lock file `~/.drydock/projects.json.lock`. Directory from `user.home`, same as `UserConfig.defaultConfigFile()`. +- Shared-store code lives in package `app.drydock.projects` and is **byte-identical** in `app/src/main/java` and `intellij-plugin/src/main/java`. Tests are byte-identical too, in both `src/test/java/app/drydock/projects/`. +- The IDE never writes the app's `state.json`. Reading it for seeding is read-only. +- A malformed `projects.json` is never overwritten. Reads give an empty list plus one WARNING. Writes fail with `SharedProjectsException`. +- Opening a project never registers it. Registration happens only through the "Add" row or by starting a task. +- The task name is never sent to the agent. Instructions start empty. An empty instruction means no initial prompt. +- Worktree base comes from `UserConfig.worktreesDirectory()` (`~/.drydock/config.json`), default `~/dev/wt`. The folder is `WorktreeNaming.defaultDirectory(home, base, repoName, branch)`. +- The default start point is the remote's default branch: `origin/<GitStatusService.defaultBranch>` when that remote ref exists, else the local default branch. +- AGENTS.md rules: + - Blocking git, filesystem and shared-file work stays off the EDT, with visible progress that is cleared on every path. + - Processes run through `ProcessRunner`; ref arguments use `--end-of-options`. + - Dialogs opened from background completions use `ModalityState.nonModal()`. + - Imports only, never inline FQCNs. + - Dead code is deleted. +- Public platform API only.

The controller runs the full `./gradlew :app:test` (14–20 min) before Part A is called done. Subagents never run the full app suite. +- Every task that changes visible UI ends with a runIde screen-capture check, following the user memory `reference-intellij-runide-live-capture`: per-window `screencapture -l`, CGEvent clicks, osascript menus.

Supersedes the entry +points of `docs/intellij-mvp-handoff/README.md` (surface 1 "Agents ▾", surface +10 "Welcome screen: Agents tab", and the Tools › Drydock menu). The rest of +that handoff (the agent editor tab and its strip, Needs-you notifications, +the close/quit confirmation, the Done dialog) stays, with the changes below. + +## Intent + +The plugin today is reached through Tools › Drydock, and its New Agent +Session dialog is about branches and worktrees. Live use showed both are +wrong for how it is meant to be used: + +- a menu is a poor home for something used all day; it needs a visible, + always-there surface; +- the user thinks in **tasks** ("make the tool window task-centric"), not in + branches and worktrees. Branch and worktree are plumbing: generated, + editable, but something the user need not know about. + +So the plugin becomes **a parallel, agentic-task-centric view of the IDE**, +next to the IDE's own project/branch-centric one: a side tool window listing +the user's registered projects and, under each, its tasks (agent sessions), +from which the user starts tasks, sees what every agent is doing, jumps to +any of them, and stops or cleans them up. The model is the standalone +Drydock app's sidebar of registered projects. + +## Goals + +1. A **Drydock tool window** (side stripe, every IDE window) showing every + registered project and its tasks, with live status. +2. **Start a task from it** with a dialog that asks for a human-readable task + name and pre-generates everything else (branch, start point, worktree + folder, window). +3. **Switch** to any task: raise or open its window and select its agent tab. +4. **Stop** a task, or **stop it and close its window**, from the tree. +5. **Clean up** a finished task (remove worktree, optionally delete branch) + with warnings whenever work would be lost, and always a way to go ahead + anyway. +6. **One list of registered projects shared with the standalone app.** +7. Fix: Resume Conversation opens the agent's tab (done, commit `3a4f6b16`). + +## Non-goals (MVP) + +- Inferring the task name from the instructions with a small (Haiku-class) + model. A later step: the user would write only the instructions and get a + suggested name and branch. Recorded so the dialog's shape does not block it. +- **Resume Conversation…** (adopting an on-disk agent conversation Drydock + does not know yet) is dropped from the MVP. A list of titles, ids or the + last few turns is not enough to tell which conversation was doing what; + it needs a summary written by a small model. That is a later step, using + the same small-model hook as task-name inference. Resuming a task that + is already in the tree (Resume on its row or strip) is unaffected. +- Showing the standalone app's sessions in the IDE. Sessions stay with the + tool that runs them; an agent in the app's terminal cannot be attached to + an IDE tab. +- Anything on the Welcome screen (no project open). +- The "Agents ▾" toolbar widget (never built; dropped). +- The `<n> files changed` count and the Changes review (handoff surfaces + 7/8) — unchanged by this design, still pending. + +## Anti-goals + +- **Losing work silently.** Stopping a working agent, removing a worktree + with anything unmerged, or deleting a branch with unmerged commits never + happens without a warning that names what is at risk. But a warning is + never a wall: the user can always go ahead. +- **Polluting the shared project list.** Opening a project in the IDE does + not register it. +- **Two writers on one state file.** The IDE must never write the + standalone app's `state.json` (see Constraints). +- **Putting the task name into the agent's prompt.** The name is a label. + +## The tool window + +Placement: a tool window with id `Drydock`, on the left stripe by default +(like Project). Same content in every IDE window. + +``` +Drydock [＋ New task] [⟳] [⋮] +[ Search tasks and branches ] + btrace isn't in Drydock · Add ← only if this window's project is unregistered + btrace ＋ ⋯ + ● Fix probe leak on retransform ⑂ fix-probe-leak · Claude + ⑂ add-jfr-events 2 tasks + ● Add JFR events for sampling Codex · 12m + ○ Review the JFR events Claude · yesterday [Resume] + ● Explain the agent loader RO main · this window + ⑂ old-experiment no task · Start ▸ + drydock ＋ ⋯ + ● Task-centric tool window ⑂ task-centric · Claude +``` + +Agreed (layout "B", chosen from the mockups): + +- **Top level: registered projects**, by their main checkout. This window's + project first, then the rest alphabetically. +- **Under a project: its tasks.** A task's branch shows as secondary grey + text (`⑂ <branch> · <Agent>`), or `main · this window` and similar. A + worktree holding **more than one task** becomes a sub-group `⑂ <branch>` + with its tasks indented beneath. Worktrees found on disk (`git worktree + list`) **with no task** are listed with a `Start ▸` action, as in the + standalone app's sidebar. +- **Status dots** as today: blue working, amber needs you, green at prompt, + hollow not running; `RO` chip for read-only. +- **Search** filters by task name and branch across all projects. +- **Header actions:** `＋ New task` (for this window's project, or the + selected project), refresh, overflow. +- **Project row:** `＋` (new task in that project) and `⋯` with + `Remove from Drydock`. +- **Task row:** double-click = switch. Hover/row actions: switch, stop, `⋯` + (stop & close window, Done with this task…, show branch/folder, resume + when not running). + +### Registering projects + +- Deliberate only. If the current window's project (resolved to its main + checkout) is not registered, the tool window shows one row at the top: + `<repo> isn't in Drydock · Add`. One click registers it; the row then + disappears. No other nag. +- `Remove from Drydock` on a project row removes it from the list only — + never touches the repository, its worktrees, or running agents. If that + project has running agents, ask first. +- Worktrees are never registered on their own; they appear under their main + repository by discovery. +- **Starting a task registers its project.** New task (⌃⌥N, or the header + button) in an unregistered window's project is allowed, and starting the + task registers the project: starting a task is a deliberate act. +- **Agents never vanish.** Tasks running in this window's project while it + is unregistered are listed under the `<repo> isn't in Drydock · Add` row. + +### First run: seeding the shared list + +The shared file is seeded **from the standalone app's list only** (the +`repositories` of the app's `state.json`, local projects resolved to their +main checkout). The plugin's own catalog is **not** merged in: it was filled +by auto-registration and would bring that clutter along. Plugin sessions +whose project is not in the seeded list stay in the plugin's state, hidden +from the tree until the project is added. Adding it brings them back, so +plugin sessions must be matched to shared projects by **canonical main +checkout root** rather than by the plugin's old repository ids. + +Which `state.json` seeds it when several app installs exist is left to the +builder (on the author's machine there is one, in the shared +`ClaudeProjectManager` directory). If none exists, the list starts empty. Seeded projects keep the app's +existing repository ids, so the app's sessions stay linked without +rewriting. + +## New task dialog + +Opened from `＋ New task`, a project row's `＋`, or ⌃⌥N (this window's +project). Opening it for a project other than this window's is normal. + +Default view — the user types only the name: + +- **Task** (required, focused): human-readable name, e.g. "Task-centric + tool window". It is the task's label in the tree and on the agent tab. +- **What should the agent do?** (optional, multi-line). **Starts empty and + stays empty** unless the user types. If empty, the agent starts at its + own prompt with nothing sent. The task name is never sent as a prompt. +- **Agent**: Claude / Codex / pi; default = the project's last-used agent, + else the first available. +- **Mode**: Writes / Read-only. +- One summary line: `New branch <slug> from <start point> in <folder> · + Change…` + +After `Change…` (same dialog, expanded): + +- **Branch**: pre-generated slug from the task name, updated live while the + user types the name, until the user edits it. Must not collide with an + existing branch (today's "taken branch names" check). +- **From**: start point, default the remote's default branch (e.g. + `origin/main`); changeable through the IDE's own branch picker (local, + remote, tags). +- **Folder**: `<base>/<repo>-<slug>` (today's `WorktreeNaming`), editable, + with a folder chooser. Below it: `Base <base> from Settings › Tools › + Drydock · Change base…`. +- **Open in**: New window (default) / This window. + +Read-only tasks need no branch or worktree; they run in the project's main +checkout (as today's Read-only + Here). The summary line says so. + +**Worktree base** is one shared setting for all projects: the existing +`worktreesDirectory` in `~/.drydock/config.json` (`UserConfig`), which the +standalone app already reads and writes; default `~/dev/wt`. The plugin +exposes it in Settings › Tools › Drydock and in the dialog's `Change base…`. + +**Open in This window** closes the current project in this window and opens +the new worktree there.

An agent at its prompt +is stopped without asking (as today). + +## Shared registered-projects list + +Agreed: **move only the list of registered projects into one small shared +file of its own**, read and written by both the standalone app and the IDE. + +- Location: the user-level Drydock directory that already holds the shared + `config.json` — proposed `~/.drydock/projects.json` (builder may rename). +- Content: per project, at least its canonical main-checkout root and a + display name; whatever else both tools need (e.g. added-at). Repository + settings that are per-tool (last-used agent, etc.) stay in each tool's + own state. +- Writes are short "lock, re-read, change, write atomically (temp + + rename)" transactions under an OS file lock on a sibling lock file, so + neither process overwrites the other's change. Readers tolerate a + missing or malformed file (empty list + warning, per the lenient-decode + rule for non-critical data) — but a malformed file is never overwritten + by a blind save. +- Both tools notice changes made by the other (file watch or re-read on + focus); the IDE tree updates without a restart. +- **The standalone app changes too:** its repository list reads from and + writes to the shared file instead of `state.json`'s `repositories`. + Sessions, tabs, UI state stay in its per-install `state.json`. Its + sessions still reference repositories by id, so ids must be stable and + shared across both tools. + +## Constraints (verified in the code) + +- **The app's state file cannot be shared.** `StateDirectory` gives each + app install its own `state.json` behind an instance lock, because two + instances sharing one file wiped each other's sessions. The plugin stores + its own state under the IDE config path (`DrydockPluginService + .defaultBaseDir`) and must keep doing so. Only the projects list moves out. +- **Repository identity changes.** Today the plugin's catalog registers a + worktree as its own repository (R7 in `ProjectRepositoryService`). The + tree groups by main checkout with worktrees beneath, so the plugin must + resolve a session's working directory to (main repository, worktree) — + `ProjectIdentity` already finds the main checkout via `git worktree list`. +- **Core code is shared by copy, and the copies have drifted.** + `intellij-plugin/src/main/java` is an extracted copy of the app's + headless core (`app.drydock.*`). It is not identical: + `diff -rq` shows ~16 differing files, among them `ApplicationStateCodec`, + `StateDirectory`, `ManagedAgentSession`, `WorktreeService`. *My call:* no + re-sync as part of this work. The new shared-projects store is new code + and lands identically in both trees. (Implementation plan refinement: + each tool keeps its `state.json` `repositories` as a local mirror keyed by + the shared id, holding per-tool settings, so the codec does not change.) +- **Repo rules (AGENTS.md):** blocking work (git, filesystem, the shared + file) off the UI thread with visible progress cleared on every path; + processes through `ProcessRunner`; one writer per persistent state; + lenient decoding of non-critical data; dialogs opened from background + completions use `ModalityState.nonModal()` (commit `6026cf4b`). +- **Platform:** public API only (Plugin Verifier must report no internal + API usage); target IU 2025.3.3, verified against the latest too. + +## Removed + +- Tools › Drydock menu: New Agent Session…, Resume Conversation…, New + Worktree…, Check Out Branch in Worktree…. New task and `Start ▸` on a + discovered worktree replace the session and worktree actions. Resume + Conversation… goes with no replacement (see Non-goals). ⌃⌥N remains as the shortcut for New task. +- Auto-registration of every opened project. +- The handoff's Agents ▾ widget and Welcome-screen tab (not built). + +## Kept + +- The agent editor tab and strip (Stop / Resume · ~Nk tokens / ⋯), the + dimmed stopped transcript, Needs-you balloons and OS notifications, + close/quit "Stop n working agents?" — unchanged. +- The Done dialog, extended with the warnings and branch tick box above. + +## Edge cases settled after review (my calls) + +- **What counts as "not merged".** A branch is merged if its tip is an + ancestor of the local default branch or of `origin/<default>` as last + fetched (no fetch is forced), **or** the task's recorded PR state is + MERGED. The PR state covers squash and rebase merges, which a plain + ancestry check would flag on every finished task. Uncommitted and + untracked files always count, whatever the branch state. +- **Done from the tree.** Done is offered for any task, in any window, and + for a task that is not running. If the task is running, the Stop warning + comes first. If its window is open, Done closes that window, and the + window's other agents get the usual close confirmation. On a worktree + shared by several tasks, Done forgets only this task. "Remove worktree" + is offered only when no other task uses the worktree; otherwise the + dialog says which tasks still use it. +- **A second task in an existing worktree.** `Start ▸` on a discovered + worktree, and `＋` on a worktree sub-group or on a task row's ⋯, open + the New task dialog with the branch and folder fixed. The summary line + reads `In existing worktree ⑂ <branch>`, and Change… does not offer + branch or folder. +- **Writes in the main checkout** stays possible. Under Change…, a "Work + in" choice offers New worktree (default) or Main checkout, with today's + warning when a writing agent already runs there. +- **Remote (SSH) projects** registered by the app are stored in the shared + file with their kind. The IDE hides them. +- **Registration resolves to the main checkout** in both tools. The app's + "Add repository" on a worktree folder registers its main checkout. This + changes the app's current behaviour, where `rev-parse --show-toplevel` + registers the worktree itself. +- **Removing a project** removes it from the shared list, for both tools. + Each tool keeps its own sessions for that project in its own state, + hidden. Adding the project again brings them back. The IDE's "running + agents" check covers only IDE agents; the app's agents for that project + keep running. + +## Left to the builder + +- Swing component choices (tree vs list with group rows), exact paddings, + icons, hover-action rendering. +- The shared file's exact name, schema, and change-notification mechanism, + within the rules above. +- Order of work and how to split it into commits/PRs. + +## Decisions made by me, not discussed explicitly + +- The IDE tree shows only IDE sessions (the user agreed sessions stay per + tool; showing the app's sessions read-only was offered and not taken up). +- Project order: this window's project first, then alphabetical. +- ⌃⌥N opens New task for the current window's project. +- Read-only tasks run in the main checkout and skip branch/worktree. diff --git a/intellij-plugin/.gitignore b/intellij-plugin/.gitignore new file mode 100644 index 00000000..138c50ca --- /dev/null +++ b/intellij-plugin/.gitignore @@ -0,0 +1 @@ +.intellijPlatform/ diff --git a/intellij-plugin/build.gradle.kts b/intellij-plugin/build.gradle.kts new file mode 100644 index 00000000..971d19a7 --- /dev/null +++ b/intellij-plugin/build.gradle.kts @@ -0,0 +1,231 @@ +// Drydock IntelliJ plugin build — v1 ("sessions") on the IntelliJ Platform +// Gradle Plugin 2.x, replacing the v0 probe's plain-java build.

No other field changed shape between version 1 and 2, so no + * further per-field migration is needed. The {@code prState}/{@code + * prNumber} members (worktree lifecycle) were added later within version 2: + * both decode leniently -- a document without them yields {@code NONE} / + * empty, so no version bump was needed. The {@code remote} member (SSH + * remote repositories) was added leniently within version 2, like + * {@code prState}: absent or malformed decodes to null (local repo), so no + * version bump was needed and downgrades stay non-destructive. The + * {@code branchCreatedHere} member was likewise added leniently within + * version 2: every session persisted before it existed did create its own + * branch, so an absent or malformed value decodes to {@code true}, not + * {@code false} -- the opposite default would silently stop drydock from + * deleting branches it is responsible for. The {@code agentKind} member was + * likewise added leniently within version 2: sessions persisted before + * multi-agent support existed have no {@code agentKind} and decode as + * {@link app.drydock.agent.api.AgentKind#CLAUDE}; an unrecognized value + * (e.g. from a dropped or renamed provider) is retained but forced to + * {@link SessionStatus#UNSUPPORTED_AGENT} rather than discarded or thrown. + * The repository {@code settings.lastUsedAgent} member was likewise added + * leniently within version 2: an absent or unrecognized value decodes to + * {@link app.drydock.domain.RepositorySettings#DEFAULT} (no preference) + * rather than throwing. The {@code namePinned} member was likewise added + * leniently within version 2: unlike {@code branchCreatedHere}, an absent or + * malformed value decodes to {@code false}, not {@code true} -- a session + * persisted before this member existed was never pinned, and an unreadable + * value must not silently lock a name a human never confirmed. + * The persisted id/name fields were renamed from {@code claudeSessionId}/ + * {@code claudeSessionName} to {@code agentSessionId}/{@code + * agentSessionName}; {@link #fromJson} accepts both the new and legacy + * names for one migration window, while {@link #toJson} only ever writes + * the new names. {@link #toJson} + * always writes the current version. Any {@code schemaVersion} other than 1 + * or 2 is treated as malformed input (throws {@link StateDecodeException}), + * consistent with how unknown versions were already rejected before this change. + * The {@code evalMode} member was likewise added leniently within version 2: + * an absent or malformed value decodes to {@code false} -- a session persisted + * before eval mode existed was never on the eval account, and an unreadable + * value must not silently route a session's traffic to it. No version bump + * was needed and downgrades stay non-destructive. + * The session {@code mode} member was likewise added leniently within version + * 2: an absent or unrecognized value decodes to {@link SessionMode#WRITES} -- + * every session persisted before read-only sessions existed was a writing + * session, and defaulting the other way would silently strip edit rights from + * a session whose owner believes it still has them. + * The {@code handoffBriefs} array and the session {@code forkedFrom} member + * were likewise added leniently within version 2: an absent {@code + * handoffBriefs} decodes to an empty list, an absent or unparseable {@code + * forkedFrom} to empty (a session persisted before it existed was not a fork), + * and {@code author} defaults to {@code AGENT} because every brief written + * before that member existed came from {@code session_handoff}. A malformed + * <em>brief</em> entry is dropped rather than throwing -- unlike a malformed + * session, which still fails the decode: a session is the user's work, a brief + * is only a note about it, so one bad note must not cost the whole state file. + * The {@code openSessionIds} and {@code selectedSessionId} members + * (session tab restoration) were likewise added leniently within version 2: + * absent or malformed values decode to an empty list and no selection, so + * no version bump was needed and older builds simply reopen with no tabs. + * The {@code reviewScopeChoices} member (per-session Review sub-tab scope, + * see {@code SessionReviewScopes.Choice}) was likewise added leniently + * within version 2: an entry whose key is not a parseable {@code + * ManagedSessionId} names no session and is dropped, while an entry whose + * value is unrecognized still names a real session and decodes through + * {@code Choice.fromPersisted} (which maps it to {@code LOCAL}) rather than + * being dropped. An absent member decodes to an empty map, so no version + * bump was needed and older builds simply ignore it. + * The {@code reviewKeyHintsHidden} member (whether the tour's key-hints strip + * was hidden) is likewise lenient: absent or not a boolean decodes to + * {@code false}, hints shown. The {@code reviewStepPanelWidth} member (the width + * the reader dragged the tour's step panel to) is lenient the same way: absent, + * not a number, non-finite or not positive decodes to 0, the default width; the + * view clamps a stored value at the point of use rather than rewriting it here. + * No version bump was needed and downgrades stay non-destructive.</p> + */ +public final class ApplicationStateCodec { + + public static final int SCHEMA_VERSION = 2;

Deliberately excluded: the +`third_party/ghostty` submodule pointer, and the untracked notes belonging to +other investigations. + +Nothing pushed, and **no PR**: a third-finished MVP would cost a reviewer a +pass over scaffolding the remaining surfaces will keep moving. + +## The model (unchanged in ownership, changed in presentation) + +- **Application** — durable session catalog (`ApplicationStateStore`, single + writer) plus an application `MessageBus` topic (`DrydockSessionsListener`) + for fan-out. The v2 shape pushed refreshes through a static + `SessionsPanel.refreshFor(project)`; that cannot reach a widget in another + window, and reaches the Welcome screen not at all. +- **Project (= worktree window)** — `AgentExecutionService`, a + `ManagedSessionId → (ProcessHandler, TerminalExecutionConsole)` map. +- **Platform** — `ProcessHandler` events are authoritative. Editor tab events + are **presentation only**: closing the tab hides it and the agent keeps + running. + +What changed: the console is a **pinned editor tab**, not Run-tool-window +content. That comes from the UX design handoff +(`~/Downloads/Drydock IntelliJ plugin design.zip`, README.md is the spec). + +## Settled findings + +- **A registered protocol, not a LightVirtualFile.** A pinned tab is restored + by the platform from the workspace file **by URL**. A light file has none, so + drydock would have to reopen tabs itself and race the platform — the v2 + duplicate-tab bug. `AgentConsoleFileSystem` registers `drydock-agent` with + the session id as the path, and `findFileByPath` answers for any valid id + even before the catalog loads (restore runs during that load). +- **A tab's label and icon do not come from `FileEditor`.** The platform builds + them from `editorTabTitleProvider` and `fileIconProvider`. A `getName()` + returning the agent's title still shows a bare session id. + `FileEditorManagerEx.refreshIcons()` makes a status change repaint the dot. +- **There is no public pin key.** `FileEditorManagerKeys` has + `FORBID_PREVIEW_TAB` but nothing for pinned; pinning is + `EditorWindow.setFilePinned`, in an `impl` package that Plugin Verifier does + **not** flag as internal. +- **`DeprecatedVirtualFileSystem` is not `@Deprecated`** — the name is about + its old listener API. It is the right base for a non-physical filesystem. +- **Console threading is forced.** `KillableProcessHandler`'s constructor runs + a blocking PTY fork/exec; `TerminalExecutionConsole`'s builds Swing. So: + spawn off the EDT, hop to the EDT for the console, `startNotify()` **last** + (a TUI's opening screen is most of what the user sees). The hop must not take + `project.getDisposed()` as an expiry condition — an expired runnable is + dropped silently, leaving the start future pending and the row at STARTING. +- **Stop is non-soft plus a 2 s force-kill.** Soft stop sends SIGINT, which pi + reads as "cancel the turn" (Phase 0B: Stop at 23:10:28, still terminating at + 23:10:54). +- **Read-only flags, read off the installed CLIs, not recalled.** Claude + `--permission-mode plan` (gated on a `--help` probe for the flag *and* the + `plan` choice — an unlisted choice is a startup error); Codex + `--sandbox read-only` (verified parseable before the subcommand, so one + placement serves create and resume); **pi has none** — `enforcesReadOnly()` + returns false and the chip reads "Read-only · not enforced". +- `SessionMode` rides on `AgentBinding` and persists leniently, defaulting to + `WRITES` — the opposite default from `namePinned`, because silently stripping + edit rights from a session whose owner believes it has them is the worse + failure. +- **pi writes no session record until a conversation turn completes.** Proved + on disk: no session file was created on the test day at all, and today's + launch *appended* to an Oct-16 session (`custom 2026-10-18T15:21:51Z`). So + `discover` and `resolve` finding nothing is correct, not a bug — do not + "fix" discovery on that symptom. `PI_SESSION_ID`, which the provider already + injects, is a per-launch proxy-correlation value, **not** pi's session + identity. +- **The agent session id is bound at termination**, with a resume-time + backstop for an IDE killed outright. A known id is never replaced: rebinding + would silently resume the wrong transcript, which looks like success and is + worse than the picker. `resolve` filters by the claimed set but does not add + to it, so the service makes the claim. +- **No conversation to resume → the strip offers `Start`, not `Resume`** + (`find-resume-only-when-resumable`). Starting fresh runs the provider's + *create* command on the existing row; `startSession` refuses a row that + already has an id, and `persistSession` upserts so it cannot mint a + duplicate row. + +## Refuted dead ends — do not revisit + +- Terminal tool-window tabs as the execution owner; all of + `TerminalSessionLauncher`, `SessionTabRegistry`, `TerminalTabGuard`, + `SessionLifecycleMonitor`, `SessionsPanel`, `SessionsToolWindowFactory`, + `SessionListModel`, `SessionEventSink` is **deleted**. +- `RunProfile` ownership, persisted or ephemeral: native Rerun starts a + process outside drydock's registry. +- A `LightVirtualFile` for the console tab, and drydock reopening tabs on + project open. +- Soft termination anywhere in the lifecycle. +- Inventing pi read-only out of `--exclude-tools`. +- Binding `PI_SESSION_ID` as the agent session id. +- "Fixing" discovery because a stopped session had no id — on the gate's + evidence there was no record to find. +- Custom `platformTest`/`testIde` source sets — they cannot boot + `BasePlatformTestCase`; use the standard `test` source set. + +## Open questions + +- **Make pi PRESET?** `pi --help` documents `--session-id <id> Use exact + project session ID, creating it if missing` — the same contract that makes + Claude PRESET. See `q-pi-preset-session-id`. +- The handoff's status table names no word for RUNNING with **unreadable** + activity, which is most live sessions — only Claude ships an + `ActivityReporter`. Interim answer: `SessionDots.statusWord` returns + `"Running"`, a fifth word the handoff does not sanction. Needs confirming. +- Two strip controls (`Changes`, `⋯`) currently show an explicit "not built + yet" message rather than doing nothing. They land in P7–P9. +- `ThreadLeakTracker` failed one `test` run and did not reproduce on + `clean test`. Flaky; watch it rather than chasing it. + +## Immediate next step + +**First: manually check P3**, in `runIde` via Tools → Drydock → New Agent +Session… (⌥⌘N). The path that matters is the new worktree one, because it +crosses a project boundary: worktree created off the repository's *default* +branch, opened as its own window, agent started there without waiting for +indexing. Also worth checking that a Read-only Claude session shows +`Read-only · won't edit files` while pi shows `Read-only · not enforced`. + +Then pick one: + +- **P2-P9**, in the handoff's order: Agents widget, New Agent Session dialog, + attention balloons, close/quit confirmation, Welcome tab, review in the + Commit tool window (plan for S4's fallback -- a Drydock Review tab on + `ChangesBrowserBase`), diff decoration, `Finish` / "Done with this session". +- **Decide `q-pi-preset-session-id`** first: pi documents + `--session-id <id> Use exact project session ID, creating it if missing`, + the same contract that makes Claude PRESET. Switching pi would delete a whole + class of discovery flakiness. Verify the flag empirically before building on + it. + +Also still unverified: **stop/resume with an actual conversation**. The gate +exercised keystrokes only, so no agent ever wrote a session record and the +late-binding path has never had anything to bind.
