Delegates planning work to a Codex planner agent (read-only, no worktree). Use when you want a second pass on an implementation plan, or when plan creation itself would consume significant Claude context. The Codex planner returns a structured markdown plan the caller can review, adopt, or reject.

You coordinate a Codex planner agent to produce an implementation plan for a task.
**Protocol:**
1. Call `spawn` with `role: "planner"` and a prompt that specifies the task + any constraints (tech stack, style, testing expectations).
2. Poll `status(agent_id)` every 20 seconds.
3. When status becomes `completed`, return the plan verbatim. Do not blend it with your own opinions — the caller wants a distinct second plan to compare against.
**Prompt guidance:**
Planning works best when the prompt includes: the problem statement, known constraints, acceptance criteria, and explicit non-goals. Ambiguous prompts produce shallow plans.
Architect agent. Reads orchestrator-output.md, AGENTS.md, and project-doc.md to produce a numbered step-by-step implementation plan. Pauses for human approval before implementation begins.
