Orchestrate

Claude-Codex Orchestration

Claude coordinates and verifies focused agent work. Codex handles scoped implementation and review through its native CLI. Prefer Codex as the first mover for bounded coding tasks.

Use this skill for one focused agent cycle inside an orchestration run. The workflow skill owns planning, run initialization, task decomposition, closure, and reporting. Return to it when the focused phase is complete.

Durable Run

Keep run material under:

.codex-orchestrator/runs/<run-id>/
  journal.jsonl
  <provider>-<role>-<NN>/execution-<NN>/
    prompt.md
    events.jsonl
    handoff.md
  evidence/                 # optional
  report.md                 # after run_closed

journal.jsonl is Claude's append-only orchestration journal. Read ${CLAUDE_PLUGIN_ROOT}/docs/orchestration-contract.md before creating or interpreting journal entries; it owns record fields, authority, validation, and closure semantics.

Capture each execution's exact prompt, raw events when available, and exact handoff. Never synthesize a log or rewrite a handoff. Keep small observations inline and create evidence/ only when material output must be retained.

Focused Agent Cycle

1. Read the complete journal, current task, and relevant references before acting.
2. Confirm the task's acceptance criteria and allowed/owned files.
3. Compare active task files and shared resources before parallel work; serialize overlap or use a worktree.
4. Reuse a relevant agent or create a named one. For an independent review, start a fresh agent and native session.
5. Resolve the execution's absolute worktree, full HEAD, and attached branch when present and include them in its record. Save the exact prompt and append execution before launch.
6. Monitor with the bundled tools without editing files owned by the active agent.
7. Save the exact handoff, inspect it and the repository, then append terminal execution_result.
8. Evaluate acceptance criteria and record material checks as verification.
9. Record only consequential resolutions or user dependencies as decision.
10. After evaluating the criteria, append complete when they are satisfied, failed when they are conclusively unmet and no in-scope recovery remains, or blocked when a user or external dependency prevents completion or judgment. Otherwise keep the task active and return the unresolved work to the workflow.

Routine bounded work needs Codex implementation plus Claude verification. Add a fresh reviewer only for material risk or a distinct unresolved question; do not repeat identical reviews.

Reference Map

Read only what the current phase needs:

• references/monitoring.md: execution capture, CLI monitoring, and handoffs.
• references/review.md: verification and independent review.
• references/consensus.md: consensus and decision outcomes.
• references/compute.md: parallel ownership, worktrees, and compute gating.
