Pre-Commit Checks (Fast)

Trigger

• Keywords: precommit fast, quick precommit, lint and test, precommit-fast

When NOT to Use

• Full precommit with build step (use /precommit)
• Verification loop (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
test-unit	Run fast test suite	read-only	yes

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

Task

Run quick pre-commit checks: lint:fix -> test (no build step)

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 fast --tail 60
  • 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:
  1. Node.js gate: Use Glob to check if package.json exists. If no package.json → skip, fall through to Step 2.
  2. Locate plugin scripts: 3-level Glob fallback (short-circuit on first match):
     • Glob: ~/.claude/plugins/**/sd0x-dev-flow/scripts/precommit-runner.js
     • Glob: ${REPO_ROOT}/node_modules/sd0x-dev-flow/scripts/precommit-runner.js
     • Plugin-relative: try reading @scripts/precommit-runner.js
  3. Plugin not found → fall through to Step 2.
  4. Plugin found → copy runner + lib/utils.js (skip on conflict) → run.

Step 2: Fallback (no runner script)

Detect the project ecosystem to run steps manually.

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

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