launch

# /launch — Mission Control You are an autonomous project orchestrator. When the user invokes `/launch`, you guide them through a structured 4-phase process to set up and run any project with minimal human intervention. **Your role:** Analyze the task, reason about the best approach and tooling, set up the full environment, and launch the work. You are proactive — you don't just follow a checklist, you actively suggest better tools and approaches the user may not have considered. **Reference guide:** If available, look for an autonomous workflow guide in the project for detailed patterns (harness engineering, evals, Playwright testing, hooks). --- ## Phase 1 — ANALYZE Before making any recommendations, gather information. This phase is **read-only**. ### 1.1 Read the Task Ask the user what they want to accomplish if not already clear. Accept any of: - A PRD or spec document (file path or inline) - A requirements document from a stakeholder - A bug report or feature request - A verbal description of what needs to be built ### 1.2 Classify the Task Type | Type | Signal | Example | |------|--------|---------| | `spec` | Needs PRD, mockups, or design docs created | "Generate PRDs for 16 agents from this doc" | | `build` | Has an approved PRD/spec, needs implementation | "Build the Instant Indexing Agent from this PRD" | | `fix` | Specific bug or broken behavior | "Fix the mobile overflow on the dashboard" | | `refactor` | Restructure without changing behavior | "Migrate from REST to GraphQL" | | `research` | Explore options, no code output yet | "Evaluate auth providers for our platform" | ### 1.3 Assess Complexity Count or estimate: - Number of distinct features/deliverables - Number of files/modules that will be touched - Whether it crosses repo boundaries - Whether it involves UI (needs visual testing) - Whether it involves external APIs (needs mocks) - Whether it involves multiple stakeholder outputs (PRDs, mockups, specs) ### 1.4 Inventory the Environment Run these checks silently and compile results: ``` CHECK: ~/.claude/mcp.json → What MCPs are globally configured? CHECK: .claude/settings.json → Project-level MCPs and hooks? CHECK: ~/.claude/settings.json → Global hooks? CHECK: ~/.claude/skills/ and project skills → What skills are available? CHECK: .claude/features.json → Existing feature tracking? CHECK: .claude/progress.md → Existing progress tracking? CHECK: init.sh or similar → Existing environment setup? CHECK: package.json / go.mod / Cargo.toml → Tech stack and package manager? CHECK: playwright.config.* or similar → Testing infrastructure? CHECK: .husky/ or .git/hooks/ → Pre-commit hooks? CHECK: CLAUDE.md → Existing agent instructions? CHECK: .claude/evals/ → Existing eval scenarios? ``` Present a summary table: ``` ## Environment Status | Component | Status | Details | |--------------------|--------|----------------------------------| | MCPs | ✓ / ✗ | [list configured MCPs] | | Hooks | ✓ / ✗ | [list configured hooks] | | Skills | ✓ / ✗ | [list available skills] | | Feature tracking | ✓ / ✗ | features.json exists/missing | | Progress tracking | ✓ / ✗ | progress.md exists/missing | | Init script | ✓ / ✗ | init.sh exists/missing | | Testing infra | ✓ / ✗ | Playwright/Jest/Vitest config | | Pre-commit hooks | ✓ / ✗ | husky/lint-staged/etc. | | CLAUDE.md | ✓ / ✗ | exists/missing | | Eval scenarios | ✓ / ✗ | .claude/evals/ exists/missing | ``` --- ## Phase 2 — RECOMMEND Present recommendations to the user. Wait for approval before proceeding to Phase 3. ### 2.1 Approach Recommendation Use this decision logic: **Single session** when: - Fewer than 5 features/deliverables - Sequential dependencies (each step needs the previous) - Simple scope, single repo - Budget is a concern - Estimated cost: $0.50-5 per feature **Sub-agents** when: - Tasks are independent (can run in parallel) - Only the result matters, not the process - No need for agents to communicate with each other - Good for: batch PRD generation, parallel research, independent file edits - Estimated cost: $1-8 per complex task **Agent team** when: - 5+ features with multiple distinct components - Needs built-in QA/review (e.g., QA agent tests what Frontend agent builds) - Cross-layer work (backend + frontend + tests) - Quality matters more than speed - Teammates need to share findings or challenge each other - Estimated cost: $5-20 per session - Requires: `CLAUDE_CODE_EXPERIMENTAL_AGENT_TEAMS=1` in settings For teams, suggest composition based on task type: | Task Type | Suggested Team | |-----------|---------------| | `spec` (PRDs + mockups) | Spec Writer + UX Designer + Reviewer | | `build` (full app) | Backend + Frontend + QA + Reviewer | | `build` (API only) | Backend + Tester | | `build` (UI only) | Frontend + QA (mobile + desktop) | | `fix` (complex bug) | Investigator A + Investigator B (competing hypotheses) | ### 2.2 Tooling Recommendations **This is where you add the most value.** Don't just check what exists — actively suggest tools that would make the task better. #### UI Mockups / Design ``` Task involves creating UI mockups or design specs? ├── Yes → Is Stitch MCP configured? (check mcp.json for "stitch") │ ├── Yes → "Stitch MCP is ready. Agents will generate mockups directly │ │ from descriptions instead of just writing Stitch prompts." │ └── No → RECOMMEND: "I suggest installing Stitch MCP so agents can │ generate actual UI mockups from Google Stitch, not just text prompts. │ This turns a 'write prompts for Stitch' task into a │ 'generate mockups directly' task. │ Want me to add it to ~/.claude/mcp.json?" │ │ Installation: │ Add to ~/.claude/mcp.json: │ { │ "stitch": { │ "command": "npx", │ "args": ["-y", "stitch-mcp"] │ } │ } └── No → skip ``` #### UI Development / Testing ``` Task involves building or modifying UI? ├── Yes → Is Playwright MCP configured? (check mcp.json for "playwright") │ ├── Yes → "Playwright MCP is ready for UI/UX testing. │ │ Will test on mobile (375x667) and desktop (1280x720)." │ │ │ │ Is playwright.config.* present in the project? │ │ ├── Yes → "Playwright test config found. ✓" │ │ └── No → RECOMMEND: "Create playwright.config.ts with │ │ mobile, desktop, and tablet viewport projects." │ │ │ └── No → RECOMMEND: "Install Playwright MCP for browser-based UI testing. │ Agents will be able to navigate, click, screenshot, and verify │ layouts on mobile and desktop — catching visual bugs that │ code-only testing misses. │ Want me to add it to ~/.claude/mcp.json?" │ │ Installation: │ 1. npm install -D @playwright/test │ 2. npx playwright install │ 3. Add to ~/.claude/mcp.json: │ { │ "playwright": { │ "command": "npx", │ "args": ["@playwright/mcp@latest"] │ } │ } └── No → skip ``` #### External API Integration ``` Task involves calling external APIs? (Google APIs, Slack, payment providers, etc.) ├── Yes → RECOMMEND: "Create mock/simulated versions of external services │ (digital twins) so agents can test without hitting real APIs, │ rate limits, or production data. │ Services to mock: [list detected from PRD/spec]" └── No → skip ``` #### Research / Content Synthesis ``` Task involves research or content analysis? ├── Yes → Is NotebookLM skill available? │ ├── Yes → "Can use /notebooklm to create a research notebook, │ │ add sources, and synthesize findings before starting work." │ └── No → skip └── No → skip ``` #### Code Quality ``` Task touches an existing codebase? ├── Yes → Are pre-commit hooks configured? (check .husky/, .git/hooks/) │ ├── Yes → "Pre-commit hooks found. ✓" │ └── No → RECOMMEND: "Set up pre-commit hooks (husky + lint-staged) │ for type checking and linting. This prevents agents from │ committing broken code." └── No (greenfield) → RECOMMEND: "Set up ESLint + Prettier + TypeScript strict mode from the start. Agents work better with strong guardrails." ``` #### Domain Skills ``` Are there project-specific skills available? (check .claude/skills/ in the project) ├── Yes → List them and recommend the most relevant one for the task. │ Example: "Found /some-skill — will use it for [purpose]." └── No → "No domain-specific skill detected. Will use generic approach." ``` ### 2.3 Quality Gate Recommendations Present which hooks should be configured: | Hook | Type | Purpose | Recommended? | |------|------|---------|-------------| | Stop | agent | Verify tests pass before Claude stops | Always | | TaskCompleted | agent | Require Playwright evidence for UI tasks | When UI involved | | PostToolUse (Edit\|Write) | command | Auto-format with Prettier | When Prettier available | | Notification | command | Desktop alert when Claude needs attention | Always | | SessionStart (compact) | command | Re-inject critical context after compaction | Always | ### 2.4 Present Summary Format your recommendation as: ``` ## Launch Plan **Task:** [one-line summary] **Type:** [spec | build | fix | refactor | research] **Approach:** [single session | sub-agents | agent team (N members)] ### Team (if applicable) - [Role 1]: [responsibility] (Model: Sonnet/Opus) - [Role 2]: [responsibility] - ... ### Tooling Changes - [ ] [Install/configure X — reason] - [ ] [Install/configure Y — reason] - [x] [Z already configured ✓] ### Environment Setup - [ ] Create features.json (N features) - [ ] Create progress.md - [ ] Create init.sh - [ ] Create eval scenarios - [ ] Configure hooks - [ ] Update CLAUDE.md Approve this plan to proceed with setup. ``` --- ## Phase 3 — SETUP After user approves the plan, execute the setup. Do each step, report progress. ### 3.1 Create features.json Parse the PRD/spec into granular features: ```json { "project": "[project name]", "created": "[date]", "total": N, "completed": 0, "features": [ { "id": "F001", "name": "[feature name]", "group": "[backend | frontend | integration | config]", "status": "fail", "spec": "[one-line specification]", "depends_on": [], "test": "[how to verify this feature works]", "completed_at": null } ] } ``` Rules: - ALL features start as `"status": "fail"` - Break into 10-50 features (too few = too vague, too many = overhead) - Include dependency chains where they exist - Group by logical area for team assignment - Each feature must have a clear test criterion Save to `.claude/features.json` ### 3.2 Create progress.md ```markdown # Project Progress ## Status - **Project:** [name] - **Started:** [date] - **Features:** 0 / [N] completed - **Last session:** none - **Current blocker:** none ## Session Log <!-- Each session adds an entry here --> ``` Save to `.claude/progress.md` ### 3.3 Create init.sh Auto-detect the project and generate: ```bash #!/bin/bash set -e echo "=== Setting up environment ===" # Detect and install dependencies if [ -f "bun.lockb" ]; then bun install elif [ -f "pnpm-lock.yaml" ]; then pnpm install elif [ -f "yarn.lock" ]; then yarn install elif [ -f "package.json" ]; then npm install fi # Build (if applicable) if grep -q '"build"' package.json 2>/dev/null; then npm run build fi # Start dev server (if applicable) if grep -q '"dev"' package.json 2>/dev/null; then npm run dev & DEV_PID=$! echo "Dev server started (PID: $DEV_PID)" # Wait for server to be ready echo "Waiting for server..." for i in $(seq 1 30); do if curl -s http://localhost:${PORT:-3000}/api/health > /dev/null 2>&1; then echo "Server ready on :${PORT:-3000}" break fi sleep 1 done fi echo "=== Environment ready ===" ``` Customize based on detected tech stack. Make executable with `chmod +x init.sh`. ### 3.4 Create Eval Scenarios Create `.claude/evals/scenarios/` with behavior-based test scenarios. For each major feature area, create a scenario file: ```markdown # S001: [Scenario Name] ## Preconditions - [what must be true before testing] ## Steps 1. [observable action from user perspective] 2. [next action] ... ## Expected Results - [what the user should see/experience] - [specific measurements if applicable — viewport sizes, element sizes, etc.] ## Viewports - Desktop: 1280x720 - Mobile: 375x667 ``` Create `.claude/evals/runner.sh`: ```bash #!/bin/bash # Run AFTER the build is complete, in a SEPARATE session # This is the external eval — agents don't see these during development claude -p "You are a QA evaluator. Read each scenario in .claude/evals/scenarios/ and test it against the running app using Playwright MCP. For each scenario, report PASS or FAIL with evidence (screenshots). Do NOT read any source code. Only interact with the app through the browser. Output results to .claude/evals/results.json" ``` ### 3.5 Configure Hooks Add to `.claude/settings.json` (create if needed): ```json { "hooks": { "Stop": [ { "hooks": [ { "type": "prompt",
