Sanctify

Run this project's own quality checks (or the subset named in $ARGUMENTS) and report exactly what passed, what failed, and the single most useful thing to do next.

1. Detect the toolchain

Find the checks this project actually defines; never invent commands:

• Node: read package.json scripts for typecheck/tsc, test, lint, build. Pick the runner from the lockfile present: pnpm-lock.yaml → pnpm, yarn.lock → yarn, otherwise package-lock.json → npm.
• Make: a Makefile with targets like test, lint, check.
• Other languages: cargo test/cargo clippy/cargo build, go test ./.../go vet, pytest plus ruff/mypy, or the equivalent the repo is set up for.

If $ARGUMENTS names a subset (e.g. "just tests", "lint"), run only that. Otherwise run the full relevant set. State which checks you found in one line before running.

2. Run each available check

Run them in cheap-to-expensive order (typecheck, lint, tests, then build only if it is quick). For each:

• Capture exit code and output.
• A non-zero exit (or a runner's own failure summary) is a FAIL.
• If a check isn't defined in the project, skip it and say so; don't substitute your own.

3. Report results

One clear line per check:

• PASS: typecheck (tsc)
• FAIL: tests (3 failing)

For each failure, excerpt the actual failing output (the assertion, the error, the offending lines), not the whole log. Point to the path:line involved as a clickable reference so the user can jump straight there.

4. Verdict and next step

End with a one-line verdict (all green, or N checks failing) and the single most useful next action (e.g. "fix the type error in src/api.ts:42, then re-run", or "all checks pass, ready to commit").

This command is read-only apart from running the checks. Do not fix, edit, or commit anything unless the user explicitly asks; report the failures and stop.
