Quality Commit

Run all quality gates (lint, typecheck, Semgrep, CodeRabbit, tests) on staged changes, then commit. This replaces the manual multi-step process that frequently causes pre-commit hook friction.

Steps

1. Determine Scope

Identify which workspace(s) have staged changes:

cd "$CLAUDE_PROJECT_DIR"
STAGED=$(git diff --cached --name-only --diff-filter=ACMR)

Categorize staged files into:

• frontend: apps/frontend/src/**/*.{ts,svelte,js}
• api: apps/api/src/**/*.ts
• shared: packages/shared/src/**/*.ts

If no files are staged, print a warning and exit.

2. Lint Staged Files

For each workspace with staged files:

• frontend: cd apps/frontend && npx eslint <staged-files>
• api: cd apps/api && npx eslint <staged-files> (if eslint is configured)
• shared: cd packages/shared && npx eslint <staged-files> (if eslint is configured)

On failure: Print the specific errors. Do NOT proceed to commit. Fix the issues first.

3. Type Check

Run type checks only on affected workspaces:

• frontend: cd apps/frontend && npx svelte-check --tsconfig ./tsconfig.json --threshold error
  • Note: 11 pre-existing errors in test files are known baseline — ignore those.
• api: cd apps/api && npx tsc --noEmit
• shared: cd packages/shared && npx tsc --noEmit

On failure: Print errors. Do NOT proceed.

4. Semgrep Security Scan

Important: Semgrep crashes when given multiple file arguments (Invalid_argument: invalid path bug in 1.146.0–1.151.0+). Always scan files one at a time:

SEMGREP_FINDINGS=""
for f in <staged-files>; do
  RESULT=$(semgrep scan --config auto --json "$f" 2>/dev/null) || true
  SEMGREP_FINDINGS="$SEMGREP_FINDINGS$RESULT"
done

• Parse JSON output from each file and aggregate findings with file:line and rule ID.
• On critical/high findings: Block the commit and show the findings.
• On medium/low findings: Warn but allow proceeding (print them for visibility).
• If semgrep is not installed, skip with a warning.

5. CodeRabbit Review (Optional)

If $ARGUMENTS contains --review or --full:

coderabbit review --plain -t uncommitted 2>&1

• Parse output and group by severity (Critical, Suggestions, Positive).
• On critical findings: Block the commit and show details.
• If coderabbit CLI is not installed, skip with a warning.

6. Run Related Tests

For each staged .ts/.svelte file, look for a colocated .test.ts:

# Example: src/lib/server/auth/rbac.ts → src/lib/server/auth/rbac.test.ts
# Example: src/routes/chat.ts → src/routes/chat.test.ts

Run discovered test files with npx vitest run <test-files> --reporter=verbose.

On failure: Print failing tests. Do NOT proceed.

7. Commit

If all gates pass:

1. Review the staged diff one more time.

2. Draft a commit message following the project convention:

   type(scope): description
   
   Co-Authored-By: Claude Opus 4.6 <noreply@anthropic.com>

3. Create the commit using a HEREDOC for the message.

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

8. Push (only with --push)

If $ARGUMENTS contains --push:

1. Run semgrep on files from the last commit (one file at a time — see Step 4 note on multi-file bug):

   COMMITTED_FILES=$(git diff --name-only HEAD~1 -- '*.ts' '*.svelte' '*.js')
   SEMGREP_FINDINGS=""
   for f in $COMMITTED_FILES; do
     RESULT=$(semgrep scan --config auto --json "$f" 2>/dev/null) || true
     SEMGREP_FINDINGS="$SEMGREP_FINDINGS$RESULT"
   done

   • On critical/high findings: Abort push, print findings. The commit stays intact.
   • On medium/low findings: Warn but continue.
   • If semgrep is not installed, skip with a warning.

2. Determine branch and upstream:

   BRANCH=$(git rev-parse --abbrev-ref HEAD)
   UPSTREAM=$(git rev-parse --abbrev-ref @{u} 2>/dev/null || echo "")

3. Push:

   • If upstream exists: git push
   • If no upstream: git push -u origin $BRANCH
   • If --dry-run is also set: Print "would push to origin/$BRANCH" and skip the actual push.

4. On push failure: Report the error. The commit remains intact — do NOT attempt to undo it.

If --push is not passed, skip this step entirely.

9. Summary

Print a summary table:

| Gate        | Status | Details                    |
|-------------|--------|----------------------------|
| Lint        | PASS   | 5 files, 0 errors          |
| TypeCheck   | PASS   | api + frontend             |
| Semgrep     | PASS   | 0 findings                 |
| CodeRabbit  | SKIP   | (use --review to enable)   |
| Tests       | PASS   | 3 test files, 12 tests     |
| Commit      | DONE   | abc1234                    |
| Push        | PASS   | pushed to origin/feature-x |

When push is not requested, show:

| Push        | SKIP   | (use --push to enable)     |

Arguments

• $ARGUMENTS: Optional flags:
  • --review or --full: Include CodeRabbit review (slower, ~30s)
  • --dry-run: Run all gates but skip the actual commit (and push)
  • --push: After successful commit, run semgrep on committed files and push to remote
  • --message "custom message": Use a custom commit message instead of auto-generating one
  • If empty: Run lint + typecheck + semgrep + tests + commit (skip CodeRabbit, skip push)

Error Recovery

If any gate fails:

1. Print the specific errors clearly
2. Suggest targeted fixes
3. Do NOT attempt to auto-fix and retry — let the user (or agent) fix first, then re-run /quality-commit

Examples

• /quality-commit — Standard flow: lint, typecheck, semgrep, tests, commit
• /quality-commit --review — Full flow with CodeRabbit review included
• /quality-commit --dry-run — Validate everything but don't commit or push
• /quality-commit --push — Standard flow + push after commit
• /quality-commit --review --push — Full flow with CodeRabbit + push
• /quality-commit --push --dry-run — Run all gates, print "would push", skip actual commit and push
• /quality-commit --message "fix(security): add IPv6 SSRF checks" — Custom commit message
