# Onboard Developer onboarding pipeline. Composes `/map-codebase`, `/review-tooling`, and `/review-agentic-setup` with inline agents, then synthesizes everything into `.turbo/onboarding.md` and `.turbo/onboarding.html`. Analysis-only. ## Task Tracking At the start, use `TaskCreate` to create a task for each phase: 1. Launch all agents 2. Synthesize and generate markdown report 3. Generate HTML report ## Step 1: Launch All Agents Emit all 6 Agent tool calls below in one assistant message. Each Agent call uses `model: "opus"` and no `name`. Wait for every agent to report before continuing. Do not begin the next step on a partial set, and do not relaunch an agent that has not yet reported. Each Composed Skills agent invokes its assigned skill via the Skill tool; each Inline Agent follows its exploration brief directly. Every agent's prompt must direct it to treat the shared working tree and its git index as read-only and to explore by reading and reasoning, except that each Composed Skills agent writes the report files its own skill defines. HEAD stays where it is: read other refs with `git show <ref>:<path>` rather than `git checkout` or `git switch`. ### Composed Skills Launch one Agent tool call per row. Each agent's prompt instructs it to invoke its assigned skill via the Skill tool. | Skill | Onboarding role | |---|---| | `/map-codebase` | Architecture understanding: structure, tech stack, entry points, patterns, data flow, dependencies, testing | | `/review-toolin...
