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)

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