Quality Commit

When to Use

Load this skill when the user request matches the frontmatter description for Quality Commit.

Run all quality gates on staged changes, then commit. Replaces manual multi-step commit prep that frequently causes pre-commit hook friction.

NEVER

• Never run git add . or git add -A — always stage specific files by name.
• Never commit after partial gate failures by bypassing hooks — gates exist for correctness.
• Never let optional tools (CodeRabbit, Semgrep) block the workflow when not installed — skip with warning.
• Never widen scope to unrelated repo cleanup during commit prep.
• Never attempt to auto-fix gate failures and retry — report errors, let the agent fix first.

Decision: What Gates to Run

Has staged files?
├─ No → Print warning, exit
└─ Yes →
    ├─ Always: Lint → TypeCheck → Semgrep → Tests → Commit
    ├─ --review or --full: Add CodeRabbit (slow, ~30s) before commit
    └─ --push: After commit, Semgrep committed files, push to remote

Gate Execution

Scope detection

STAGED=$(git diff --cached --name-only --diff-filter=ACMR)
bash scripts/classify-staged-files.sh  # categorizes into frontend/api/shared

Semgrep: file-at-a-time (critical workaround)

Semgrep 1.146.0+ crashes with multiple file arguments (Invalid_argument: invalid path). Always loop:

for f in $STAGED_FILES; do
  semgrep scan --config auto --json "$f" 2>/dev/null || true
done

Block on critical/high findings. Warn on medium/low. Skip if not installed.

TypeCheck workspace commands

• frontend: npx svelte-check --tsconfig ./tsconfig.json --threshold error (11 pre-existing errors in test files are known baseline — ignore)
• api: npx tsc --noEmit
• shared: npx tsc --noEmit

Related test discovery

node scripts/find-related-tests.js <staged-file>
# src/lib/server/auth/rbac.ts → src/lib/server/auth/rbac.test.ts

Run discovered tests: npx vitest run <test-files> --reporter=verbose

Commit message format

type(scope): description

Co-Authored-By: Claude Opus 4.6 <noreply@anthropic.com>

Types: feat, fix, refactor, test, docs, chore Scopes: security, phaseX.Y, api, frontend, database, auth, workflows

Push flow (--push only)

1. Re-run Semgrep on committed files (same file-at-a-time loop, use git diff --name-only HEAD~1)
2. Detect upstream: git rev-parse --abbrev-ref @{u} 2>/dev/null
3. If no upstream: git push -u origin $BRANCH, else git push
4. Abort push on critical/high Semgrep findings — commit stays intact, do NOT undo it

| Semgrep    | PASS   | 0 findings                 |
| CodeRabbit | SKIP   | (use --review to enable)   |
| Tests      | PASS   | 3 test files, 12 tests     |

Arguments

• --review / --full: Add CodeRabbit review
• --dry-run: Run all gates, skip actual commit and push
• --push: Commit then semgrep + push to remote
• --message "...": Use custom commit message
