# Launch > Mission control for autonomous projects — analyzes tasks, recommends approaches (sub-agents/teams), sets up environment (features, evals, hooks, init.sh), suggests and configures tooling (MCPs), and launches the work. - **Type:** Skill - **Install:** `agentstack add skill-devotts-build-it-launch` - **Verified:** Yes — security-reviewed for prompt injection and unsafe behavior - **Seller:** [DevOtts](https://agentstack.voostack.com/s/devotts) - **Installs:** 0 - **Category:** [AI & ML](https://agentstack.voostack.com/c/ai-and-ml) - **Latest version:** 0.1.0 - **License:** MIT - **Upstream author:** [DevOtts](https://github.com/DevOtts) - **Source:** https://github.com/DevOtts/build-it/tree/main/plugins/build-it/skills/launch ## Install ```sh agentstack add skill-devotts-build-it-launch ``` Requires the [AgentStack CLI](https://agentstack.voostack.com/docs/cli). Works with Claude Code, Cursor, and any MCP-compatible agent. ## About # /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). --- ## Invocation modes - **Interactive (default)** — a human ran `/launch` directly. The approval gates in Phase 2 and Phase 4.2 present recommendations and WAIT. - **Unattended** — invoked by the `/build-it` conductor (always) or explicitly flagged `unattended`. Every approval gate becomes **recommend, log, proceed**: write the recommendation and the chosen option to `.taskstate/decisions.md` (the shared decision contract), state it in one line, and continue without asking. An unattended run must reach Phase 4.3 with zero turns spent waiting on a human. **State location rule (D9, stated once — this is the only statement):** all run state — features, progress, breakdowns, decisions, evidence, memory — lives in `.taskstate/` at the workspace root, versioned per project (e.g. `features-v3.json`). `.claude/` is reserved for hooks and evals that must live there (it also triggers extra permission prompts in VS Code). Every later mention of those files defers to this rule. --- ## 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: .taskstate/features-*.json → Existing feature tracking? (use latest by version) CHECK: .taskstate/progress-*.md → Existing progress tracking? (use latest by version) 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? ``` Feature/progress file locations follow the state location rule (top of this file). Present a summary table: ``` ## Environment Status | Component | Status | Details | |--------------------|--------|----------------------------------| | MCPs | ✓ / ✗ | [list configured MCPs] | | Hooks | ✓ / ✗ | [list configured hooks] | | Skills | ✓ / ✗ | [list available skills] | | Feature tracking | ✓ / ✗ | .taskstate/features-*.json | | Progress tracking | ✓ / ✗ | .taskstate/progress-*.md | | 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 the recommendations. **Direct human invocation: wait for approval before proceeding to Phase 3. Unattended: do not emit an approval question — log the recommendation + chosen approach to `.taskstate/decisions.md` and proceed straight 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." ``` #### LLM Observability / Tracing ``` Task involves LLM calls? (OpenAI SDK, OpenRouter, LangChain, direct API calls) ├── Yes → Is LangSmith configured? (check for LANGSMITH_API_KEY in .env or env vars) │ ├── Yes → "LangSmith tracing is configured. ✓" │ │ │ │ Is `wrapOpenAI` used? (check for langsmith/wrappers import) │ │ ├── Yes → "Token + cost tracking via wrapOpenAI. ✓" │ │ └── No → RECOMMEND: "Upgrade from @traceable to wrapOpenAI │ │ for automatic token counts (input/output/total) │ │ and cost estimates per call. @traceable alone │ │ captures inputs/outputs/latency but NOT tokens." │ │ │ └── No → RECOMMEND: "Install LangSmith for LLM observability. │ Captures token usage, cost estimates, latency, and │ full input/output traces for every LLM call. │ Want me to set it up?" │ │ Setup: │ 1. Install: `npm install langsmith` (or `uv add langsmith`) │ 2. Add to .env: │ LANGSMITH_TRACING=true │ LANGSMITH_ENDPOINT=https://api.smith.langchain.com │ LANGSMITH_API_KEY= │ LANGSMITH_PROJECT= │ LANGCHAIN_PROJECT= # JS SDK reads THIS, not LANGSMITH_PROJECT │ │ 3. Wrap the OpenAI client (works with OpenRouter too): │ import { wrapOpenAI } from 'langsmith/wrappers'; │ export const client = wrapOpenAI(new OpenAI({ ... })); │ │ 4. For accurate cost tracking, pass ls_model_name: │ await client.chat.completions.create( │ { model, messages, ... }, │ { langsmithExtra: { metadata: { ls_model_name: model.replace(/^[^/]+\//, '').replace(/\./g, '-') } } } │ ); │ │ Key insight: wrapOpenAI emits LLM-flavored LangSmith runs │ with token counts + cost. @traceable only gets latency + I/O. │ When using OpenRouter, costs are directional (LangSmith's │ built-in price table, not OpenRouter's margin); token counts │ are always correct. └── No → skip ``` #### 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] (tier: [cheap/mid/top] — [one-line reason]) - [Role 2]: [responsibility] (tier: …) - ... Tiers come from the **delegation routing rule** — the canonical table in `../references/model-tiers.md` §2–3 (relative to this skill's base directory; ships with the plugin — reference it; never copy it). Gates: default = inherit the session model when unsure; never downgrade the verifier, anything writing to `decisions.md`, or a packet locking an interface others consume; escalate on struggle rather than pre-paying — a lower-tier worker that fails its contract after one corrected re-dispatch, or thrashes, is re-run one tier up; log each tier choice, reason, and escalation to `.taskstate/run-memory.md`. ### 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. ``` (Unattended: replace the closing line with "Proceeding — plan logged to `.taskstate/decisions.md`.") --- ## 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 `.taskstate/features-[version].json` (per the state location rule). ### 3.2 Create progress.md ```markdown # Project Progress ## Status - **Project:** [name] - **Started:** [date] - **Features file:** [absolute path to .taskstate/features-*.json] - **Features:** 0 / [N] completed - **Last session:** none - **Current blocker:** none ## Session Log ``` Save to `.taskstate/progress-[version].md` (per the state location rule). ### 3.3 Create init.sh Auto-detect the project and generate: ```bash #!/bin/bash set -e echo "=== Se … ## Source & license This open-source skill is cataloged on AgentStack and links to its original source — we do not rehost the code. - **Author:** [DevOtts](https://github.com/DevOtts) - **Source:** [DevOtts/build-it](https://github.com/DevOtts/build-it) - **License:** MIT Install and usage instructions live in the source repository linked above. ## Pricing - **Free** — Free ## Security capabilities Automated source analysis of v0.1.0 — what this tool can access: - **Network access:** yes - **Filesystem access:** no - **Shell / process execution:** no - **Environment & secrets:** yes - **Dynamic code execution:** no *"Yes" means the capability is present in the source — more access means more to trust, not that it is unsafe.* ## Versions - **0.1.0** — security scan: passed — Imported from the upstream source. ## Links - Listing page: https://agentstack.voostack.com/l/skill-devotts-build-it-launch - Seller: https://agentstack.voostack.com/s/devotts - Browse the marketplace: https://agentstack.voostack.com/browse --- Listed on AgentStack — the marketplace for AI agent skills and MCP servers.
