Every finding carries its rule, the skill it came from, and a repo-relative path with forward slashes so the same report works on any runner.

Competing scanners emit SARIF for skill content; none of them also measures the token cost or catches the source-vs-output drift, which is the failure a repo with eleven compile targets actually hits.

v0.18.0

+ 2026-08-09latest +
+

Kitbash in CI. Everything it checks — the install-gate safety lints, the declared token budgets, the compiled output's drift from its source — was previously a thing one maintainer ran locally and everyone else took on trust. This release makes it a required check on the pull request instead.

+

Added

  • kitbash lint --sarif <file> — writes findings as SARIF 2.1.0, the format GitHub code scanning reads, so results land in the Security tab and as inline PR annotations rather than scrolling past in a log. Hard-fail safety lints (remote-exec, visible-text, dynamic-context, secrets) are error; heuristics and cost overruns are warning; passing checks are not emitted, so a clean run produces a valid, empty report rather than noise. Every finding carries its rule, the skill it came from, and a repo-relative path with forward slashes so the same report works on any runner. The report is written even when the lint fails — that is exactly the run whose findings need to reach the Security tab — and never outside the project (exit 2 if a path tries).
  • A GitHub Action (singhharsh1708/kitbash@v0.18.0) — one step, three checks. It lints every installed skill for trust and budget, uploads SARIF, and then recompiles to catch drift: if kitbash compile changes anything in the working tree, the committed output no longer matches its source and the build fails with the diff. Competing scanners emit SARIF for skill content; none of them also measures the token cost or catches the source-vs-output drift, which is the failure a repo with eleven compile targets actually hits. Composite, so it runs on every runner OS with no image pull: with: strict, drift, sarif, sarif-file, version, working-directory.

v0.17.0

- 2026-08-08latest + 2026-08-08

The eleventh target — and it's the one the whole industry just agreed on. On 2026-08-06 OpenAI, Amazon, Microsoft, Cursor and Vercel published Agent Plugins v1.0 (agent-plugins.org, Google core-maintaining): a vendor-neutral package format — a plugin.json manifest plus a skills/<name>/SKILL.md folder — that ChatGPT/Codex, Cursor, Copilot, Kiro and VS Code all read. It is a packaging standard by design: it defines no permission model, no trust or provenance, no sandboxing, and no measurement. That absence is exactly the layer Kitbash already is. So rather than treat the standard as a competitor, Kitbash compiles to it.
