Skill 09 — Collab Coordinator

Purpose: Run Codex Collab as a Standard lane accelerator: coordinate read-only helpers and synthesize findings for the single writer.

Protocols:

• •[[docs/PROTOCOLS/LANES]]
• •[[docs/PROTOCOLS/COLLAB]]
• •[[docs/PROTOCOLS/VAULT_PROBE]]
• •[[docs/PROTOCOLS/EVIDENCE]]
• •[[docs/PROTOCOLS/RUN_LOGGING]]
• •[[docs/PROTOCOLS/CONTEXT_BUDGET]]

Inputs (from Orchestrator)

• •docs/tasks/<task_slug>.md (required)
• •Optional: specific questions / areas to investigate
• •Optional: helper count (default 2–4)

Outputs (must write)

• •docs/notes/<task_slug>_collab.md (brief + synthesis)
• •artifacts/collab_summary.json
• •[[docs/skills/09_collab_coordinator/SUMMARY]]

Run log (mandatory)

Create: artifacts/_runs/<timestamp>_09_collab_coordinator/

Steps

1. •Confirm the lane is Standard. If Slow triggers are present, stop and recommend upgrading to Slow lane.
2. •Produce a Collab brief that enforces:
   • •single writer (Orchestrator)
   • •helpers are read-only
   • •evidence pointer format (path:Lx-Ly)
   • •timebox and scope boundaries
3. •Define 2–4 helper roles (Context Scout / Risk Reviewer / AC Checker / Diff Reviewer).
4. •Collect helper outputs and synthesize:
   • •key findings + evidence pointers
   • •risks / open questions
   • •recommended next skill(s)
5. •Write docs/notes/<task_slug>_collab.md.
6. •Write artifacts/collab_summary.json with:
   • •task_slug
   • •helpers (roles + assignments)
   • •findings (bullets)
   • •evidence (array of {path, from, to, why})
   • •risks (array)
7. •Write SUMMARY.md.

Definition of Done

• • Collab note exists and declares single-writer rule
• • Collab summary JSON exists
• • Summary exists and links outputs
