Commit

Pre-commit quality workflow with atomic commits.

When to Use

• User says "commit", "/commit", "commit my changes"
• After completing a feature or fix
• Before pushing changes

Workflow

Execute in order. Stop on failure.

0. Scope Check

Only commit changes relevant to this conversation/thread.

• Review the conversation history and plan file (if present)
• Identify files created/modified as part of this task
• Ignore unrelated changes in the working tree
• If unsure, ask user which changes to include

# Show all changes, but only stage task-relevant files
git status

1. Detect Submodules

Check for git submodules:

git submodule status

If submodules exist with changes:

1. Enter each submodule with changes
2. Run full workflow (lint, format, type-check, commit) inside submodule
3. Return to parent repo
4. Stage submodule pointer update

# Check for submodule changes
git diff --submodule
# Enter submodule
cd <submodule-path>
# ... run workflow ...
cd ..
# Stage submodule update
git add <submodule-path>

2. Detect Project Type

Check changed files to determine toolchain:

git diff --cached --name-only
git diff --name-only

• *.ts, *.tsx, *.js, *.jsx → TypeScript toolchain
• *.py → Python toolchain
• Mixed → run both toolchains

3. Run Quality Gates

Run format, lint, typecheck, and tests. Always prefer project-defined scripts over hardcoded language tooling — most repos already have a make check target or a bun run check / npm test script that bundles their exact toolchain (biome vs oxlint vs eslint, tsc vs tsgo, etc.). Only fall through to language defaults when no project script exists.

Detection order

For each gate (format, lint, typecheck, test), try entries top-to-bottom and use the first that exists:

1. Makefile target (preferred — projects pin their full toolchain here):

# Composite gate (covers everything in one shot when present):
make -n check 2>/dev/null && make check
make -n ci 2>/dev/null && make ci

# Per-gate targets:
make -n format 2>/dev/null && make format
make -n lint 2>/dev/null && make lint
make -n typecheck 2>/dev/null && make typecheck
make -n test 2>/dev/null && make test

2. package.json scripts (TypeScript/JS):

# Composite first — many projects have `check` or `check:strict`:
jq -e '.scripts."check:strict"' package.json && bun run check:strict
jq -e '.scripts.check' package.json && bun run check
jq -e '.scripts.ci' package.json && bun run ci

# Per-gate scripts:
jq -e '.scripts.format' package.json && bun run format
jq -e '.scripts.lint' package.json && bun run lint
jq -e '.scripts.typecheck' package.json && bun run typecheck
jq -e '.scripts.test' package.json && bun run test

3. pyproject.toml scripts (Python):

# uv-managed task runners vary; check for the convention used in the repo:
uv run -- task check 2>/dev/null || uv run pytest

4. Language defaults (only if nothing above exists):

# TypeScript fallback:
bunx biome lint --write .
bunx biome format --write .
bunx tsc --noEmit

# Python fallback:
uv run ruff check --fix .
uv run ruff format .
uv run ty check .          # fallback: uv run basedpyright .
uv run pytest

What "first available" means

• A composite script (check, check:strict, ci, make check) covers all four gates — running it satisfies format + lint + typecheck + test and the per-gate steps below can be skipped.
• If the composite is missing, run the per-gate scripts individually using the same priority order.
• If a per-gate script is missing AND no language default applies (e.g. a Go-only repo), skip that gate with a note rather than inventing a command.

Why detection > hardcoding

Hardcoding bunx biome or bunx tsc will run the wrong tools in projects that use oxlint/oxfmt/tsgo/eslint and either silently produce no findings or emit confusing errors. The project's own scripts encode the right toolchain choice — trust them.

If lint or format mutates files, re-stage the changes before the commit step.

4. Extract Issue References

Scan the conversation for issue references from:

• Linear: PROJ-123, BACKEND-4ZW (uppercase prefix + alphanumeric ID)
• GitHub: #123, org/repo#123, or GitHub issue URLs
• Sentry: Sentry issue URLs like https://sentry.io/issues/... or issue IDs like PROJ-123

If found, include in commit message body (not title). Format:

type(scope): message

Refs: BACKEND-4ZW

For fixes that close an issue:

fix(scope): message

Closes: BACKEND-4ZW

5. Atomic Commits

Group related changes. Each feature/fix gets its own commit.

1. Review changes: git diff
2. Stage related files: git add <files>
3. Commit with convention format (include issue refs if found)
4. Repeat for remaining changes

Commit Convention

Format: type(scope): message

Scope is required - use affected area (api, auth, db, ui, cli).

Type	Use for
feat	New features
fix	Bug fixes (reference issue: fix(auth): resolve login #123)
refactor	Code restructuring (no behaviour change)
perf	Performance improvements
docs	Documentation only
test	Adding or updating tests
build	Build system, dependencies, CI/CD
style	Formatting, whitespace (no logic changes)
chore	Maintenance, config, tooling
revert	Reverting a previous commit
hotfix	Urgent production fixes

Examples

# Single feature
git add src/auth/*.ts
git commit -m "feat(auth): add JWT refresh token support"

# Bug fix with GitHub issue reference
git add src/api/users.ts tests/api/users.test.ts
git commit -m "fix(api): handle null user in profile endpoint #142"

# Fix with Linear issue reference (multiline via heredoc)
git add opennem/tasks/app.py
git commit -m "$(cat <<'EOF'
fix(worker): pass WorkerSettings as positional arg

Sentry ArqIntegration expects settings_cls as args[0], not kwarg.

Closes: BACKEND-4ZW
EOF
)"

# Feature with Sentry issue reference
git add src/error-handler.ts
git commit -m "$(cat <<'EOF'
fix(errors): handle null response in API client

Refs: SENTRY-ABC123
EOF
)"

# Multiple atomic commits from one session
git add src/components/Button.tsx
git commit -m "feat(ui): add loading state to Button"

git add src/utils/format.ts
git commit -m "refactor(utils): extract date formatting helpers"

Notes

• If lint/format changes files, re-stage before commit
• Prefer small, focused commits over large batches
• Keep commit messages concise (<72 chars first line)
• Don't commit generated files, build artifacts, or secrets
• Always check conversation for issue refs (Linear, GitHub, Sentry) and include them
• Use Closes: for fixes, Refs: for related work
