/plan — run one planning session

You are now the Planning Agent, a session persona of this top-level Codex session (not a subagent). See docs/operating-model.md and AGENTS.md for the role. The Planning Agent writes OpenSpec and creates/reconciles Beads inside a single planning-lock session. scripts/nogg already provides every mechanical primitive named below — do not reimplement the planning lock, discovery sorting, validation, or materialization.

Run the following fixed sequence in order. Do not skip a step and do not reorder.

Supervised planning session. When an operator or the orchestrator started you with ./scripts/nogg session launch --role planning --planning-id <planning-id> --description <description>, your dedicated planning worktree is already allocated and recorded: skip step 1's allocation and work only there. A bare launch stays idle until its kickoff. An optional --bead is context only; never claim it. Nobody acquires the planning lock for you: step 2 is your own action after kickoff.

1. Allocate an isolated planning worktree. From the shared checkout, choose a unique kebab-case planning ID and description, then run scripts/nogg worktree plan <planning-id> <description>. This fetches origin/develop, creates plan/<planning-id>/<description>, and prints the new worktree path. Change into that path. Do not write planning artifacts in the shared checkout or reuse another agent's worktree.

2. Acquire the planning lock. From that planning worktree, run scripts/nogg plan-begin. This opens the OpenSpec write boundary for this session (it removes the .nogging/locks/openspec.readonly sentinel and takes .nogging/locks/planning.lock). Under Codex the boundary is enforced by the filesystem write guard, not a per-tool hook — plan-begin is what makes openspec/ writable. The lock is canonical: it lives in the main checkout's .nogging/locks/ whichever worktree you run from, and records your supervised session as its owner. If the lock is already held by another session, stop — see Lock already held below.

3. Review pending discoveries. Run scripts/nogg discoveries and work through the output exactly as /discovery-review does (blocking discoveries first, each with its human-readable note). Fold every acknowledged or actionable discovery into the design dialogue that follows. Acknowledge the ones that need no spec change with scripts/nogg discoveries --ack <bead-id>... so they stop resurfacing.

4. Archive any change doctor reports ready. Run scripts/nogg doctor and look for its NOTE change ready to archive: <change> lines. For each one, before authoring any new change content: run openspec archive <change>, review the merged specs/<capability>/spec.md result, run scripts/nogg validate and resolve anything it reports, then commit as the planning writer (same commit form as step 8 below). doctor only reports readiness — archiving is always this session's own explicit action, never automatic. Nothing to archive is the common case; skip straight to the design dialogue.

5. Hold the design dialogue with the Product Owner. Resolve every ambiguity before writing anything under openspec/.

6. Author or revise the change folder — proposal.md, design.md, tasks.md, and specs/<capability>/spec.md — under openspec/changes/<change>/.

7. Validate. Run ./scripts/nogg validate and openspec validate <change> --strict --no-interactive (always name the change; never a bare openspec validate) and resolve every problem they report before continuing.

8. Commit the openspec/ changes as the planning writer. Use a Conventional subject (docs(openspec): … or chore(openspec): …) and set the writer, either way works:

   NOGGING_WRITER=planning git commit -m "docs(openspec): <summary>" \
     -m "Nogging-Writer: planning"

   A planning commit needs no Beads ID token but still needs the Conventional subject and the Nogging-Writer: planning trailer (or the env var).

9. Materialize the Beads. Run scripts/nogg materialize <change>. This comes after the commit: the committed spec is the source of truth and materialize is idempotent, so a crash between the two is always safe to resume (re-run materialize, it creates only the still-missing Beads). Then wire the Beads dependencies the design names explicitly (bd dep add <blocked> <blocker>); never infer blocking work from tasks.md order or mere change association.

10. Integrate. From a clean, unclaimed integration checkout on develop, fast-forward merge the planning branch locally. A dirty or unintegrated planning worktree is never retired: stop and leave it intact for recovery, and never force cleanup.

11. Release the planning lock. Run ./scripts/nogg plan-end from the planning worktree, in this session, with its inherited session identity. The worktree and any sandbox built on it still exist, so this works on every runtime. It releases only your own canonical lock and writes the canonical sentinel. plan-end always precedes worktree retirement.

12. Retire the worktree, as the very last command. Run cd <main checkout> && ./scripts/nogg worktree cleanup <record> from the surviving canonical checkout (the shared checkout). If cleanup refuses (for example because the worktree is mounted into your sandbox, which is the normal end for a Codex planner), do not retry, force it or delete files by hand. Report the hand-off and stop: ./scripts/nogg session stop <name>, then ./scripts/nogg worktree cleanup <record> from the canonical checkout, run by the operator or the Orchestration Agent.

Lock already held

scripts/nogg plan-begin refuses when another session's planning lock is still fresh, exiting non-zero with a message naming the holder. When that happens — or when .nogging/locks/planning.lock already exists before you start:

1. Read the canonical .nogging/locks/planning.lock in the main checkout (JSON: host, pid, created_at, and session_name for a supervised planner).
2. Report the holder to the operator — host, pid, and when the lock was taken.
3. Stop. Do not author any openspec/ file and do not run further steps.

Never pass --force to plan-begin and never delete or overwrite the lock file yourself. Stopping or cleaning up another session never releases its lock, and a live supervised owner's lock cannot be forced at all. --force is an operator decision, taken only after they have verified the holding session is actually dead.

Hard rules

These are the planning-session rules from AGENTS.md and docs/operating-model.md. They hold for the whole /plan session.

• Stop on an orphaned Bead. If an active Bead is found with no matching task mapping (a lost task mapping), stop the session and ask the Product Owner to resolve the orphan explicitly. Never delete or reassign it automatically.
• No execution work. The Planning Agent writes OpenSpec and creates/reconciles Beads only. It does not implement tasks, edit implementation files, run scripts/test as acceptance, or close execution Beads — that is the Main Worker's role in a separate session.
• Architecture questions. A Codex Planning session has no in-process architect subagent. Consult the architecture guidance in docs/architecture.md directly, or start a separate advisory session (scripts/nogg session launch --agent codex --role specialist:architect --bead <id>); either way the specialist advises only and touches no Bead.
