Yolo Skill

Full-auto AI-DLC pipeline. User provides a prompt; agent drives the entire lifecycle: Idea -> Elaboration -> Proposal -> Review -> Execute -> Verify -> Done.

---

Overview

/yolo automates the complete AI-DLC workflow. You provide a natural language description of what you want built, and the agent handles everything:

1. Planning -- create project, idea, self-elaboration, proposal with docs & tasks
2. Proposal Review -- proposal-reviewer adversarial loop
3. Execution -- wave-based parallel task dispatch via spawn_agent
4. Verification -- task-reviewer adversarial loop + admin verify
5. Report -- completion summary

/yolo <prompt>
       |
       v
  Project + Idea + Elaboration + Proposal
       |
       v
  Proposal Reviewer (auto, up to maxProposalReviewRounds)
       |
       v
  Admin Approve --> Tasks materialize
       |
       v
  Wave-based spawn_agent parallel execution
       |  (dev agent + task-reviewer per task)
       v
  Admin Verify each wave --> unblock next
       |
       v
  Done. Report summary.

Escape hatch: Ctrl+C at any time. All created entities (project, idea, proposal, tasks) persist in Chorus. Resume manually via /develop or /review.

---

Prerequisites

The API key needs write + admin on every resource it touches:

Needs	Why
idea: [write]	Create ideas, run elaboration
proposal: [write, admin]	Create proposals; approve them
task: [write, admin]	Create, execute, verify tasks
project: [write]	Create the project if none is given

Check at startup:

perms = chorus_checkin().agent.permissions
need = { idea: ["write"], proposal: ["write","admin"],
         task: ["write","admin"], project: ["write"] }

for resource, actions in need:
  missing = [a for a in actions if a not in (perms[resource] or [])]
  if missing: ABORT "/yolo needs {resource}: {missing}. Use an Admin-preset API key."

---

Input

/yolo <natural language prompt>
/yolo <prompt> --project <project-uuid>

• <prompt> -- what you want built (becomes the Idea content)
• --project <uuid> -- optional; use an existing project instead of creating a new one

---

Workflow

Phase 1: Planning

Step 1.1: Resolve Project

Parse the arguments for --project <uuid>.

If --project is provided:

chorus_get_project({ projectUuid: "<uuid>" })

Verify it exists and proceed.

If not provided, search for a suitable existing project first:

# 1. Search for projects matching the prompt topic
chorus_search({ query: "<key terms from prompt>", entityTypes: ["project"] })

# 2. Or list recent projects to find a match
chorus_list_projects()

Review the results. If a project clearly matches the user's intent (same topic, active, relevant scope), use it. If no suitable project exists, create a new one:

chorus_admin_create_project({
  name: "<short title derived from prompt>",
  description: "<1-2 sentence summary of the prompt>"
})

Step 1.2: Create Idea

chorus_pm_create_idea({
  projectUuid: "<project-uuid>",
  title: "<concise title derived from prompt>",
  content: "<full user prompt as-is>"
})

Then claim it:

chorus_claim_idea({ ideaUuid: "<idea-uuid>" })

Step 1.3: Self-Elaboration

In /yolo mode, the agent generates elaboration questions and answers them itself -- no AskUserQuestion calls. This preserves an audit trail without interrupting the user.

1. Generate and submit questions:

   chorus_pm_start_elaboration({
     ideaUuid: "<idea-uuid>",
     depth: "standard",
     questions: [
       {
         id: "q1",
         text: "<question about scope, architecture, etc.>",
         category: "functional",
         options: [
           { id: "a", label: "<option A>" },
           { id: "b", label: "<option B>" }
         ]
       }
       // ... 5-8 questions covering functional, technical, scope aspects
     ]
   })
   

2. Answer immediately (agent selects best options based on the prompt):

   chorus_answer_elaboration({
     ideaUuid: "<idea-uuid>",
     roundUuid: "<round-uuid>",
     answers: [
       { questionId: "q1", selectedOptionId: "a", customText: "Rationale: ..." },
       // ...
     ]
   })
   

3. Validate (no issues in self-mode):

   chorus_pm_validate_elaboration({
     ideaUuid: "<idea-uuid>",
     roundUuid: "<round-uuid>",
     issues: []
   })
   

Step 1.4: Create Proposal

1. Detect OpenSpec mode. Load the openspec-aware skill at ~/.codex/skills/openspec-aware/SKILL.md and run its §1 detection contract. The result determines how the rest of this step authors documents:

   • CHORUS_OPENSPEC_ACTIVE=1 → spec-driven branch (sub-step 2a below).
   • CHORUS_OPENSPEC_ACTIVE=0 → free-form branch (sub-step 2b below).

   This is mandatory — yolo runs unattended, so silently picking the wrong mode is exactly the failure scenario the detection contract exists to prevent.

2. Create the empty proposal container. In OpenSpec mode, the description MUST contain the literal line OpenSpec change slug: <slug> (use the $SLUG you'll pick in 2a); in free-form mode, omit that line.

   chorus_pm_create_proposal({
     projectUuid: "<project-uuid>",
     title: "<feature name>",
     description: "<summary>\n\nOpenSpec change slug: <slug>",   // OpenSpec mode
     // description: "<summary>",                                 // free-form mode
     inputType: "idea",
     inputUuids: ["<idea-uuid>"]
   })
   

   Then branch:

   2a. OpenSpec mode (CHORUS_OPENSPEC_ACTIVE=1). Follow openspec-aware §3 end-to-end:

   • Pick $SLUG, run openspec new change "$SLUG" (§3.1–§3.2).
   • Author proposal.md, design.md, and one specs/<capability>/spec.md per capability locally on disk (§3.3). ADDED Requirements only; per-spec fallback to free-form Markdown if MODIFIED/REMOVED is needed.
   • Define $API, json_encode_file, chorus_check_response helpers (§3.4, §6).
   • Mirror each local file via "$API" chorus_pm_add_document_draft "$PAYLOAD" (§3.6) — one call per file, with the document type from openspec-aware §5. (Codex's chorus-mcp-call.sh takes <TOOL_NAME> <JSON> directly; no mcp-tool subcommand.)

   ⛔ Do not invoke chorus_pm_add_document_draft / chorus_pm_update_document_draft / chorus_pm_update_document from Codex's MCP harness with a hand-typed content field in this branch. Re-typing the markdown body wastes 20k+ tokens per proposal and breaks byte-equality with the local files. See openspec-aware §2 Rule 1.

   Then continue to step 3 (task drafts).

   2b. Free-form mode (CHORUS_OPENSPEC_ACTIVE=0). Add a tech design document draft directly via MCP, content authored inline:

   chorus_pm_add_document_draft({
     proposalUuid: "<proposal-uuid>",
     type: "tech_design",
     title: "Tech Design: <feature>",
     content: "<markdown tech design covering architecture, data model, API, module contracts>"
   })
   

3. Add task drafts incrementally (use returned draftUuid for dependency chaining):

   # First task
   result1 = chorus_pm_add_task_draft({
     proposalUuid: "<proposal-uuid>",
     title: "<module name>",
     description: "<what to build, referencing tech design>",
     priority: "high",
     storyPoints: 3,
     acceptanceCriteriaItems: [
       { description: "<testable criterion>", required: true },
       // ...
     ]
   })
   
   # Second task, depends on first
   chorus_pm_add_task_draft({
     proposalUuid: "<proposal-uuid>",
     title: "<dependent module>",
     description: "...",
     priority: "medium",
     storyPoints: 2,
     acceptanceCriteriaItems: [...],
     dependsOnDraftUuids: ["<result1.draftUuid>"]
   })
   

4. Validate:

   chorus_pm_validate_proposal({ proposalUuid: "<proposal-uuid>" })
   

   Fix any errors, then proceed.

5. Submit:

   chorus_pm_submit_proposal({ proposalUuid: "<proposal-uuid>" })
   

   After this call, the PostToolUse hook injects context instructing you to spawn the chorus-proposal-reviewer sub-agent. You MUST spawn it yourself via spawn_agent and wait for its return with wait_agent — it is NOT auto-launched.

---

Phase 2: Proposal Review Loop

After chorus_pm_submit_proposal, the PostToolUse hook injects context instructing you to spawn the chorus-proposal-reviewer sub-agent. The reviewer is a SKILL, not a built-in agent_type — spawn it by mounting the skill into a default agent:

spawn_agent(
  agent_type="default",
  items=[
    { type: "skill", name: "Chorus Proposal Reviewer", path: "chorus:chorus-proposal-reviewer" },
    { type: "text",  text: "Review proposal <proposal-uuid>. Max review rounds: 3. Post VERDICT comment." }
  ]
)
wait_agent([reviewer_id])

Then:

1. Read the reviewer's VERDICT:

   chorus_get_comments({ targetType: "proposal", targetUuid: "<proposal-uuid>" })
   

   Look for the most recent comment containing VERDICT:.

   IMPORTANT — release thread slot: after wait_agent returns, immediately call close_agent(reviewer_id). Codex caps concurrent agent threads at 6; completed status does NOT free a slot — only close_agent does. On long $yolo runs you WILL hit the limit if you don't close each reviewer after use.

2. Act on the VERDICT:

   • PASS or PASS WITH NOTES --

     chorus_admin_approve_proposal({
       proposalUuid: "<proposal-uuid>",
       reviewNote: "PASS from reviewer. <brief summary of notes if any>"
     })
     

     Tasks and documents materialize automatically. Proceed to Phase 3.

   • FAIL -- Read the BLOCKERs from the reviewer comment. Then:

     chorus_pm_reject_proposal({
       proposalUuid: "<proposal-uuid>",
       reviewNote: "FAIL from reviewer. Fixing BLOCKERs: <list>"
     })
     

     Revise the drafts (chorus_pm_update_document_draft, chorus_pm_update_task_draft) to address each BLOCKER, then resubmit:

     chorus_pm_submit_proposal({ proposalUuid: "<proposal-uuid>" })
     

     After resubmission, the hook injects context again — spawn the reviewer yourself for Round 2.

3. Max rounds: Loop up to maxProposalReviewRounds (from plugin config, default 3). If exhausted:

   STOP: "Proposal review failed after {maxRounds} rounds. 
          Remaining BLOCKERs: <list>. Human review needed.
          Proposal UUID: <uuid>"
   

4. No new VERDICT comment after reviewer returns? The reviewer exhausted its maxTurns budget. Respawn it ONCE with a concise-budget hint: "Stay within turn budget. Skip deep source verification. Fetch proposal + comments + idea only, skim for obvious BLOCKERs, and post your VERDICT within the first 10 turns." If the second attempt still produces no VERDICT, treat the proposal as PASS WITH NOTES and proceed — the pipeline cannot loop forever on a silent reviewer.

---

Phase 3: Task Execution (Wave-Based)

After proposal approval, tasks exist in open status. Execute them in dependency-ordered waves using Codex spawn_agent. If parallel spawn is not desired or too many workers in flight, fall back to sequential main-agent execution.

Primary: Parallel spawn_agent workers

wave = 1

loop:
  # 1. Find ready tasks
  unblocked = chorus_get_unblocked_tasks({ projectUuid: "<project-uuid>" })

  if no unblocked tasks and all tasks done:
    break  # All complete

  if no unblocked tasks and some tasks not done:
    # Stuck -- tasks failed review and can't proceed
    break with escalation report

  # 2. For each unblocked task, spawn a worker
  for each task in unblocked:
    # Optional: create a Chorus session for observability
    session = chorus_create_session({ name: f"worker-{task.title[:20]}" })

    spawn_agent(
      agent_type="worker",
      message=f"""You are a Chorus developer worker. Follow the $develop skill.

      Your sessionUuid: {session.uuid}   # omit this line if no session
      Your task UUID: {task.uuid}
      Project UUID: {project_uuid}

      Implement per task description + acceptance criteria. Read task, proposal, and project documents for context. After chorus_submit_for_verify, exit and let the main agent spawn the task-reviewer."""
    )

  # 3. Wait for workers to return (use wait_agent)
  #    Each worker follows $develop skill:
  #    claim -> in_progress -> develop -> report -> self-check AC -> submit_for_verify

  # 4. Close worker sessions (main agent responsibility — no SubagentStop hook)
  for each session:
    chorus_close_session({ sessionUuid: session.uuid })

  # 5. Proceed to Phase 4 (verification) for this wave
  wave += 1

What the worker prompt needs:

• taskUuid (required)
• sessionUuid (optional — only if main agent created one for observability)
• projectUuid (required for context lookups)
• Explicit instruction to follow $develop skill — the skill itself has all the workflow detail

Fallback: Main Agent (sequential)

If parallel spawn is not practical (rate limits, token budget, or simpler debugging wanted), fall back to executing tasks sequentially as the main agent:

for each task in unblocked:
  # Follow the /develop workflow directly as main agent
  chorus_claim_task({ taskUuid: "<task-uuid>" })
  chorus_update_task({ taskUuid: "<task-uuid>", status: "in_progress" })

  # ... implement the task: read context, write code, run tests ...

  chorus_report_work({ taskUuid: "<task-uuid>", report: "..." })
  chorus_report_criteria_self_check({ taskUuid: "<task-uuid>", criteria: [...] })
  chorus_submit_for_verify({ taskUuid: "<task-uuid>", summary: "..." })

  # PostToolUse hook injects context — you must spawn task-reviewer yourself
  # Proceed to Phase 4 verification for this task before moving to next

The fallback is slower (sequential, not parallel) but still completes the pipeline. The PostToolUse hook injects reviewer instructions the same way in both modes — you must always spawn the reviewer manually.

---

Phase 4: Verification

After each wave's sub-agents complete, verify their tasks:

for each task in wave_tasks:
  # 1. Check task status
  task = chorus_get_task({ taskUuid: "<task-uuid>" })

  if task.status != "to_verify":
    # Sub-agent may have failed; skip or handle
    continue

  # 2. Spawn task-reviewer in FOREGROUND and wait for it (use wait_agent)
  #    Mount the chorus-task-reviewer SKILL into a default sub-agent
  #    (Codex only has default/explorer/worker built-in types).
  spawn_agent(
    agent_type="default",
    items=[
      { type: "skill", name: "Chorus Task Reviewer", path: "chorus:chorus-task-reviewer" },
      { type: "text",  text: "Review Chorus task <task-uuid>. Post VERDICT as a comment before exit." }
    ]
  )
  wait_agent([reviewer_id])
  close_agent(reviewer_id)   # IMPORTANT: release the thread slot (max 6 concurrent, completed != closed)

  # 3. Read task-reviewer VERDICT
  comments = chorus_get_comments({ targetType: "task", targetUuid: "<task-uuid>" })
  # Find the most recent comment containing "VERDICT:"

  # 4. Act on VERDICT — three possible outcomes:
  if VERDICT is "PASS":
    # All AC verified, no issues. Mark AC and verify.
    chorus_mark_acceptance_criteria({
      taskUuid: "<task-uuid>",
      criteria: [
        { uuid: "<ac-uuid>", status: "passed", evidence: "<from reviewer>" },
        // ...
      ]
    })
    chorus_admin_verify_task({ taskUuid: "<task-uuid>" })
    # Task is now "done" -- unblocks dependents

  if VERDICT is "PASS WITH NOTES":
    # All AC verified, minor non-blocking notes. Still mark AC and verify.
    chorus_mark_acceptance_criteria({ ... })
    chorus_admin_verify_task({ taskUuid: "<task-uuid>" })

  if VERDICT is "FAIL":
    # BLOCKERs found. Do NOT verify. Reopen for rework.
    chorus_admin_reopen_task({ taskUuid: "<task-uuid>" })
    # Task returns to "open", will be picked up in next wave

After verifying all tasks in the wave, return to Phase 3 to check for newly unblocked tasks.

Max rounds per task: Tracked by maxTaskReviewRounds from plugin config (default 3). If a task has been reopened maxRounds times, skip it and flag for human escalation:

ESCALATE: "Task '{title}' failed review after {maxRounds} rounds. 
           Last BLOCKERs: <list>. Manual intervention needed.
           Task UUID: <uuid>"

Continue with remaining tasks -- do not halt the entire pipeline for one stuck task.

No new VERDICT comment after the task-reviewer returns? It exhausted its maxTurns budget. Respawn it ONCE with a concise-budget hint: "Stay within turn budget. Skip deep verification. Fetch task/proposal/comments, run only the core tests, and post your VERDICT within the first 12 turns." If the second attempt also produces no VERDICT, treat as PASS WITH NOTES and proceed — do not loop indefinitely.

---

Phase 5: Report

After all waves complete, output a markdown summary:

## /yolo Complete

**Project:** <project-name> (<project-uuid>)
**Proposal:** <proposal-title> (<proposal-uuid>)
**Idea:** <idea-title> (<idea-uuid>)

### Tasks
| Task | Status | Review Rounds |
|------|--------|---------------|
| <title> | done | 1 |
| <title> | done | 2 |
| <title> | ESCALATED | 3 (max) |

### Summary
- Total tasks: N
- Completed: X / N
- Escalated: Y (need human review)
- Waves executed: W

---

Phase 5b: Idea Completion Report (mandatory)

A successful $yolo run always finishes the Idea — call chorus_create_report once with proposalUuid set to the last verified proposal. The tool's description carries the section template; follow it. Surface the returned documentUuid in the Phase 5 summary. Skipping is a protocol violation.

---

Error Handling

Scenario	Action
Missing permissions at startup	Abort with message listing the missing resource/action pairs (see Prerequisites). Recommend an Admin-preset API key.
Project creation fails	Report error, suggest user create project manually and retry with --project
Proposal reviewer FAIL after maxRounds	Stop pipeline, report persisting BLOCKERs, suggest manual review
Task reviewer FAIL after maxRounds	Flag task as escalation-needed, continue with other tasks
Sub-agent crash / no submit	Log error, skip task, pick it up in next wave if possible
Ctrl+C	All entities persist in Chorus. User can resume via /develop or /review

---

Tips

• Keep the initial prompt detailed -- the more context you provide, the better the auto-generated proposal quality
• The proposal-reviewer is your quality gate -- if it keeps FAILing, the prompt may be too vague
• Watch the wave count -- if tasks keep getting reopened, consider Ctrl+C and manually reviewing the feedback
• All audit trail is preserved: elaboration Q&A, reviewer VERDICTs, work reports. Check Chorus UI for full history
• For small/simple tasks, consider /quick-dev instead -- it skips the Idea->Proposal overhead
• Sub-agents share your API key; ensure it has the permissions listed in Prerequisites before starting
