precommit

Pre-Commit Checks (Full)

Trigger

• Keywords: precommit, pre-commit, lint and test, quality gate

When NOT to Use

• Quick checks without build (use /precommit-fast)
• Verification loop without lint:fix (use /verify)
• Just running tests (run directly)

Workflow Steps

Step	Goal	Safety	Skip if Missing
lint-fix	Auto-fix code style issues	read-write	yes
build	Verify compilation succeeds	read-only	yes
test-unit	Run full test suite	read-only	yes

Failure behavior: continue-all (run all steps, report all results)

Task

Run pre-commit checks: lint:fix -> build -> test

Step 1: Check for runner script

Use Glob to check if .claude/scripts/precommit-runner.js exists in the project root.

• Found → run: node .claude/scripts/precommit-runner.js --mode full --tail 80
  • If runner succeeds, use its output and skip to the Output section.
  • If runner fails, treat as a real precommit failure (do not silently fallback).
• NOT found → Auto-install attempt (see precommit-fast for identical auto-install logic), then fallback to Step 2.

Step 2: Fallback (no runner script)

Detect the project ecosystem to run steps manually.

Ecosystem detection:

Manifest	Ecosystem	Lint-fix	Build	Test
package.json	Node.js	{pm} lint:fix	{pm} build	{pm} test:ci / test / test:fast / test:unit
pyproject.toml	Python	ruff check --fix .	—	pytest tests/unit/
Cargo.toml	Rust	cargo clippy --fix	cargo build	cargo test
go.mod	Go	golangci-lint run --fix	go build ./...	go test ./...
build.gradle	Java (Gradle)	./gradlew spotlessApply	./gradlew build	./gradlew test
pom.xml	Java (Maven)	mvn spotless:apply	mvn compile	mvn test
Gemfile	Ruby	bundle exec rubocop -a	—	bundle exec rspec

For Node.js projects, auto-detect package manager from lockfile.

Step	package.json script	If missing
lint:fix	lint:fix	Skip with note
build	build	Skip with note
test	test:ci → test → test:fast → test:unit	Skip with note

After lint:fix completes, run git diff --name-only to capture auto-fixed files.
