precommit

name	precommit
description	Run the pre-commit lint/format pipeline on staged files only, mirroring what lint-staged does. Use when the user wants to lint and format staged files before committing, or says "run pre-commit", "lint staged", "format staged files".

Pre-commit Skill

Mirror the lint-staged pre-commit pipeline: auto-fix then verify, but only on staged files.

Step 0 — Identify staged files

git diff --cached --name-only --diff-filter=ACM

Split the output into two lists:

• ts_files: staged files matching *.ts or *.tsx
• css_files: staged files matching *.css under src/css/

If both lists are empty, report "No staged files to lint." and stop.

Steps (run sequentially, stop and report on any failure)

Step 1 — Format staged TS/TSX files (dprint)

Only if ts_files is non-empty:

./node_modules/.bin/dprint fmt <ts_files...>

Step 2 — Lint-fix staged TS/TSX files (oxlint)

Only if ts_files is non-empty:

./node_modules/.bin/oxlint --fix <ts_files...>

Step 3 — CSS lint-fix staged CSS files (stylelint)

Only if css_files is non-empty:

./node_modules/.bin/stylelint --fix <css_files...>

Step 4 — Verify formatting

Only if ts_files is non-empty:

./node_modules/.bin/dprint check <ts_files...>

If this fails, show which files still need formatting and stop.

Step 5 — Verify lint

Only if ts_files is non-empty:

./node_modules/.bin/oxlint <ts_files...>

If this fails, show the remaining violations and stop.

Step 6 — Verify CSS lint

Only if css_files is non-empty:

./node_modules/.bin/stylelint <css_files...>

If this fails, show the remaining violations and stop.

Output

• If all steps pass: report "Pre-commit checks passed."
• If a fix step fails: report the error output and which step failed, then stop.
• If a check step fails after fixing: show the remaining violations so the user can fix them manually.
