Defame1297 2bde9a6a82 chore(skills): bump metadata.version for the Research doc migration
Raise the PATCH version of each skill whose references/sources.md,
references, or validator changed in the Research registry migration, as
ADR-0022 requires. factory-audit and skill-author changed behaviour and
docs; the rest changed provenance metadata only.

pc-run Use when the user wants to run pre-commit hooks, wire them into git, bump hook revs, maintain the cache, or diagnose why a hook fails or never fires. Not creating or editing the pre-commit config -> `pc-author`. Requires pre-commit installed and available on PATH.

Gotchas

  • The SKIP env var takes exact hook id values, comma-separated with no spaces: SKIP=check-yaml,gitleaks rtk git commit -m "msg". A space after a comma silently skips nothing instead of erroring.
  • Never bypass a failing hook with git commit --no-verify (or -n). Hooks are the automated QA gate, so a bypassed commit pushes the failure downstream where it costs more — diagnose it instead.
  • - files were modified by this hook is not a bug. A fixer hook rewrote a staged file, so the staged snapshot is stale and the commit is blocked on purpose. Re-stage and re-run the same commit: rtk git add -u && rtk git commit. Do NOT reach for pre-commit install -f here — it overwrites .git/hooks/ and has nothing to do with re-staging.

Gate — pre-commit clean

Confirm with the user before running pre-commit clean, on every path that reaches it — including when it turns up as the fix for a stale or broken environment. It wipes the whole cache at ~/.cache/pre-commit, which is machine-wide and shared by every repo on the box, forcing every hook environment to be re-downloaded.

"This will wipe the entire pre-commit cache. All hook environments will be re-downloaded on next run. Proceed?"

pre-commit gc drops only unused environments and needs no confirmation — prefer it when the goal is just to reclaim disk.

Route

Determine intent from the user's request, then execute the matching operation. Where the matching row names a references/ file, read that one file and no other — each flow file is self-contained.

User intent Operation
"run", "check", "verify", "test hooks" pre-commit run --all-files (default)
"staged", "simulate commit" pre-commit run (staged files only)
"CI", "changed files only", "diff range" pre-commit run --from-ref <base> --to-ref <head> — prefer this over --all-files on large repos
"install", "set up hooks", "wire into git" pre-commit install — read references/install.md
"pre-create environments", "warm cache" pre-commit install-hooks — builds every hook environment without running a hook
"remove hooks", "uninstall", "tear down" pre-commit uninstall — removes pre-commit from .git/hooks/
"autoupdate", "update versions", "bump revs" pre-commit autoupdate — read references/autoupdate.md
"gc", "garbage collect" pre-commit gc — drops unused cached environments only, safe at any time
"clean", "wipe cache", "rebuild from scratch" pre-commit clean — read references/clean.md
"hooks aren't running", "hook never fires", "why did a hook fail", a hook failure whose cause is unclear Diagnose — read references/failure-patterns.md

If the intent is ambiguous, default to pre-commit run --all-files — do not stop to ask, and do not fall through to a narrower row on a guess.

Run

Default to pre-commit run --all-files; never silently narrow to staged files. Run pre-commit run (staged only) or pre-commit run <hook-id> (one named hook) when the user asks for it.

When hooks fail:

  1. Name the hook and the specific cause. Be concrete — "gitleaks blocked config.json (high-entropy string on line 12)", not "gitleaks failed".
  2. Suggest one concrete next step. Common causes and their concrete fixes are in references/failure-patterns.md — read it whenever the output does not already name the fix.
  3. Do not auto-fix code files, and do not edit .pre-commit-config.yaml — those belong to the user or to pc-author.
