/start — Development Pipeline Orchestrator

One command to rule them all. Routes your task through the right skills, guarantees test infrastructure, and won't let you claim done without proof.

Usage

/start <task description>

Pipeline

You MUST follow this sequence exactly. No shortcuts. No skipping steps.

Step 0: Test Infrastructure

This step runs EVERY time, before anything else. Do NOT skip any sub-step.

Check if testing.md exists at the project root.

If it does NOT exist:

1. Explore the project to discover:
   • Package manager (npm, pnpm, yarn, bun)
   • Test frameworks already installed (vitest, jest, playwright, etc.)
   • Scripts in package.json (test, test:e2e, test:integration, etc.)
   • Existing test files and their locations
   • Required environment variables
   • Database or service dependencies
2. Create testing.md using the template below, filled in with real values from this project:

# Testing Guide

## Environment Setup
- Package manager: [detected]
- Required env vars: [list with descriptions]
- Database: [commands to start/seed test DB, or "none"]
- Services: [docker-compose, external APIs, or "none"]

## Running Tests

### Unit Tests
Command: `[detected or recommend]`
Location: `tests/unit/`

### Integration Tests
Command: `[detected or recommend]`
Location: `tests/integration/`

### E2E Tests (Playwright)
Command: `npx playwright test`
Setup: `npx playwright install chromium`
Base URL: `[detected from config or recommend]`
Location: `tests/e2e/`

## Debugging Failed Tests
- Single test: `[framework-specific command]`
- Headed browser: `npx playwright test --headed`
- Traces: `npx playwright show-trace test-results/*/trace.zip`

3. Install Playwright if not already installed. This is NOT optional. Run:

   npm install -D @playwright/test && npx playwright install chromium
   

4. Create playwright.config.ts if it doesn't exist. Use the config template from /e2e-playwright.
5. Create tests/e2e/ directory if it doesn't exist.
6. Commit: git commit -m "chore: add test infrastructure (testing.md, playwright)"

If it exists: Read it. Then verify Playwright is installed (npx playwright --version). If not, install it now before proceeding.

Step 1: Route the Task

Read CLAUDE.md. Classify the task as one of:

Step 2: Design (features only)

Run /brainstorm-and-plan with the task description.

• The plan MUST include Playwright E2E tests for every user-facing flow
• The plan MUST include integration tests for every API route
• Wait for user approval before writing any code

After approval, proceed to Step 4.

Step 3: Root Cause Analysis (bugfixes only)

Run /debug to investigate the bug.

• Do NOT guess at fixes
• Trace to root cause first
• Once root cause is identified, proceed to Step 4

Step 4: Implement with TDD

Run /tdd for every implementation step.

For each piece of work:

1. Write a failing test
2. Run it — confirm RED
3. Write minimal code to pass
4. Run it — confirm GREEN
5. Refactor if needed
6. Commit with conventional commit message

Commit after every green cycle, not at the end.

Test Debt Handoff — before moving to Step 5:

Review the /tdd Behavior Coverage Checklist. List every E2E test owed:

E2E debts from Step 4:
- [ ] [describe the user workflow that needs an E2E test]
- [ ] [describe the nav change that needs a navigation test]
- [ ] [describe the bug fix that needs a browser-level regression test]

Carry this list into Step 5. Every item MUST be covered before Step 6.

Step 5: E2E Coverage

╚══════════════════════════════════════════════════════════════════╝

Before writing tests, verify Playwright works:

npx playwright --version  # Must output a version number

If this fails, run: npm install -D @playwright/test && npx playwright install chromium

Then run /e2e-playwright to write E2E tests covering:

• Features: Every user-facing flow introduced or changed
• Bugfixes: A test that reproduces the original bug and confirms the fix
• Refactors: Tests proving existing behavior is preserved
• API routes: Request/response tests via Playwright's request fixture

After writing E2E tests, confirm they pass:

npx playwright test --repeat-each=3

If any test is flaky, diagnose and fix before proceeding. Do NOT move on with flaky tests.

Commit screenshot baselines:

If any tests use toHaveScreenshot(), Playwright generates baseline images in *.spec.ts-snapshots/ directories. These MUST be committed — they are the source of truth for visual regression.

# Check for generated screenshot baselines
find tests/e2e -name "*.spec.ts-snapshots" -type d

# If any exist, stage and commit them
git add tests/e2e/**/*.spec.ts-snapshots/
git commit -m "test: add Playwright screenshot baselines"

Do NOT skip this. Without committed baselines, toHaveScreenshot() will fail on subsequent runs.

Screenshot requirement check:

Before answering the quality gate, run this check:

# Did this task change anything visual (CSS, HTML structure, styles, colors, layout)?
git diff HEAD~1 --stat -- '*.html' '*.css' '*.tsx' '*.jsx' '*.scss'

If that diff is non-empty, you MUST have at least one toHaveScreenshot() call in your E2E tests. No exceptions. No "computed style is good enough." No "N/A." Screenshots and computed-style assertions serve different purposes — screenshots catch visual regressions you didn't think to assert on.

If you don't have one yet, write it now before proceeding.

E2E Quality Gate — answer ALL before proceeding to Step 6:

Every question below must be answered YES or DOES-NOT-APPLY. "N/A" is NOT a valid answer for questions that apply to your task. If you're unsure whether a question applies, the answer is YES it applies — write the test.
