/ouroboros:run

Execute a Seed specification through the Ouroboros workflow engine.

Usage

/ouroboros:run [seed_file_or_content]

Trigger keywords: "ouroboros run", "execute seed"

How It Works

1. Input: Provide seed YAML content directly or a path to a .yaml file
2. Validation: Seed is parsed and validated (goal, constraints, acceptance criteria, ontology)
3. Execution: The orchestrator runs the workflow with PAL routing
4. Progress: Real-time progress updates via session tracking
5. Result: Execution summary with pass/fail status

Instructions

When the user invokes this skill:

Load MCP Tools (Required first)

The Ouroboros MCP tools are often registered as deferred tools that must be explicitly loaded before use. You MUST perform this step before proceeding.

1. Use the active runtime's tool-discovery capability to find and load the execution MCP tools:

   tool discovery query: "+ouroboros execute"

2. The tools will typically be named with prefix mcp__plugin_ouroboros_ouroboros__ (e.g., ouroboros_execute_seed, ouroboros_session_status). After runtime tool discovery returns, the tools become callable.
3. If the tools are callable — already exposed, or loaded by discovery — proceed with the steps below. An empty discovery result for already-exposed tools is expected, not a failure. Skip to the Fallback section only if they are genuinely absent (no Ouroboros MCP server).

IMPORTANT: Do NOT skip this step. Do NOT assume MCP tools are unavailable just because they don't appear in your immediate tool list. They are almost always available as deferred tools that need to be loaded first.

CRITICAL — deferred-schema guard (prevents "Invalid tool parameters"): This skill makes execution MCP calls across multiple turns, and each turn runs in a fresh tool context. A deferred tool's schema loaded on one turn is NOT guaranteed to still be loaded on the next. If you call any execution ouroboros_* MCP tool while its schema is not loaded in the current turn, the runtime rejects the call with "Invalid tool parameters" before it reaches the server. Therefore: immediately before EVERY execution MCP call in this skill, re-run tool discovery query: "+ouroboros execute" to reload the execution tool family, including ouroboros_start_execute_seed, ouroboros_job_wait, ouroboros_ac_tree_hud, and ouroboros_job_result (idempotent — a no-op when already loaded). If the load returns no matching tool (and the tool is not already callable — an empty load for an already-exposed tool is an expected no-op, not absence), switch to the documented fallback instead of retrying the failing call.

Execution Steps

1. Detect git workflow (before any code changes):

   • Read the project's CLAUDE.md for git workflow preferences
   • If PR-based workflow detected and currently on main/master:
     • Create a feature branch: ooo/run/<session_id>
     • All code changes go to this branch
   • If no preference: use current branch (backward compatible)

2. Check if the user provided seed content or a file path:

   • If a file path: Read the file with the Read tool
   • If inline YAML: Use directly
   • If neither: Check conversation history for a recently generated seed

   Before a fresh start, when no efficiency choice is already known, ask in user-outcome language: Efficient execution maps to efficiency_mode="adaptive" plus frugality_assurance="observe"; Quality-first execution maps to efficiency_mode="quality_first" plus frugality_assurance="off". strict assurance is a separate explicit opt-in because proof may cost extra. Do not ask or override these values on resume; the server restores the persisted contract.

3. Start background execution with ouroboros_start_execute_seed:

   Tool: ouroboros_start_execute_seed
   Arguments:
     seed_content: <the seed YAML>
     model_tier: "medium"  (or as specified by user)
     efficiency_mode: <adaptive or quality_first>
     frugality_assurance: <observe, off, or explicit strict>
     max_iterations: 10    (or as specified by user)

   This returns immediately with a job_id, session_id, and execution_id.

4. If resuming an existing session, include session_id:

   Tool: ouroboros_start_execute_seed
   Arguments:
     seed_content: <the seed YAML>
     session_id: <existing session ID>

5. Recommended monitoring stance: delegate one exclusive observer.

   After IDs are returned, print only this short handoff:

   Execution started in background.
   Job ID: <job_id>
   Session ID: <session_id>
   Execution ID: <execution_id>
   Live view: <response.meta.dashboard_url, or `ouroboros tui open`>
   Runtime/harness: <response.meta.runtime_backend>
   LLM backend: <response.meta.llm_backend>
   Efficiency: <response.meta.efficiency_mode>
   Frugality assurance: <response.meta.frugality_assurance>
   
   A read-only observer will report meaningful progress, attention, and terminal
   events here. This conversation remains available for requirement refinement,
   read-only review, explicit control, or unrelated work in an isolated worktree.
   For full details later: `ouroboros_ac_tree_hud(session_id=<session_id>)`

   When response.meta.job_observer is present and an independent Task/Agent child is available, spawn exactly one read-only observer and pass the contract unchanged. It exclusively owns job wait/result and the cursor. The main session must not poll the same job. Before writing to the active workspace, check worker overlap or use an isolated worktree. Do not claim an observer exists until Task/Agent returns a live child handle. On Codex, once spawn_agent returns that handle, keep the parent turn open with wait_agent calls of at most 60 seconds until the observer returns its terminal summary. Child send_message calls only queue mailbox events and cannot revive an ended parent turn. Relay meaningful updates, handle user input if it interrupts the wait, and resume waiting while the observer is active unless the user asks to stop live observation or replaces the active request. Then end only the relay loop, keep the durable job running, and offer next-turn or explicit-status catch-up. If the observer child fails, is cancelled, or exits before a terminal summary, use that same fallback instead of waiting indefinitely. This relay loop must not poll the job or take cursor ownership. If creation fails, do not promise live proactive relays. The detached worker survives the stdio turn; catch up from durable events on the next parent turn or explicit status request. Keep the fallback polling loop open only for explicit live watching.

6. Fallback low-token relay loop with ouroboros_job_wait.

   Use this only when no independent observer session exists and the user asked for live watching in this turn; otherwise catch up on the next parent turn. Never run both.

   Use ouroboros_job_wait, not repeated ouroboros_ac_tree_hud, for routine monitoring. Keep the latest cursor and previous progress counters from the tool meta payload.

   This loop is intentionally harness/model friendly:

   • Treat response.meta as the source of truth.
   • Do not parse response.text for counts, status, or cursor.
   • Use response.text only as a human-readable current-message hint.
   • Keep all local monitor state in simple scalar variables.
   • Emit at most one short relay message per changed response.
   • Always continue to final ouroboros_job_result after a terminal status.

   cursor = <cursor from start/status response, or 0>
   prev_status = "running"
   prev_phase = null
   prev_ac_completed = 0
   prev_sub_ac_completed = 0
   prev_message = null
   
   loop:
     Tool: ouroboros_job_wait
     Arguments:
       job_id: <job_id from step 3>
       cursor: <cursor>
       timeout_seconds: 180
       view: "summary"
       stream: "linked"
       wait_for: "attention_or_ac_change"
   
     cursor = response.meta.cursor
   
     if response.meta.changed is false:
       # Do not narrate unless the user explicitly asked for heartbeat updates.
       continue
   
     status = response.meta.status
     phase = response.meta.current_phase
     ac_completed = response.meta.ac_completed
     ac_total = response.meta.ac_total
     sub_ac_completed = response.meta.sub_ac_completed
     sub_ac_total = response.meta.sub_ac_total
     # The metadata field names remain legacy-compatible; relay them to users as Task/Subtask progress.
     message_hint = first non-empty non-metadata line from response.text, or null
   
     # Build one short relay update from structured fields.
     if status in ["completed", "failed", "cancelled", "interrupted"]:
       print terminal_relay(status, phase, ac_completed, ac_total, sub_ac_completed, sub_ac_total)
       break
   
     if ac_completed > prev_ac_completed:
       print task_progress_relay(phase, ac_completed, ac_total, sub_ac_completed, sub_ac_total, message_hint)
     elif sub_ac_completed > prev_sub_ac_completed:
       print subtask_progress_relay(phase, ac_completed, ac_total, sub_ac_completed, sub_ac_total, message_hint)
     elif phase != prev_phase or status != prev_status:
       print phase_or_status_relay(status, phase, ac_completed, ac_total, sub_ac_completed, sub_ac_total)
     elif message_hint != prev_message:
       print current_work_relay(phase, ac_completed, ac_total, sub_ac_completed, sub_ac_total, message_hint)
   
     prev_status = status
     prev_phase = phase
     prev_ac_completed = ac_completed or prev_ac_completed
     prev_sub_ac_completed = sub_ac_completed or prev_sub_ac_completed
     prev_message = message_hint or prev_message

   Notes:

   • timeout_seconds: 180 means the MCP call can block for up to 3 minutes. This keeps the main session available often enough for a live relay while still avoiding noisy polling.
   • Use view: "compact" for very long jobs or when the user only wants a heartbeat. The raw tool may still return legacy text such as job_x | running | AC 3/17; relay that to users as Task progress.
   • Use view: "summary" for normal monitoring. It includes the job message plus Task/Subtask counts derived from legacy ac_completed/sub_ac_completed metadata fields.
   • Use view: "full" only when the user asks for detailed job status.

   Relay style examples:

   • In progress: Deliver is at Task 1/3 and Subtask 12/16. Current work is the Subtask 3 regression test.
   • Level update: parallel level 1/1 has finished, and Task progress advanced to 3/3.
   • Completed: execution finished. Fetching the final job result now.

   Relay output contract for other harnesses/models:

   • One update should be 1-2 sentences or 1 compact line.
   • Include phase, Task completed/total and Subtask completed/total when present.
   • Include the current work hint only if it changes.
   • Never include the full task tree in routine relay output.
   • Never include raw JSON, raw meta dumps, or repeated unchanged cursor lines.
   • Terminal statuses must be explicit: completed, failed, cancelled, or interrupted.

   Interpret meta.relay_events as structured user-facing facts:

   • run_configuration: current runtime/harness, starting model or tier when known, efficiency mode, and frugality assurance.
   • execution_plan: total ACs and dependency/parallel levels, whether work is parallelizable, and the first scheduled AC summaries.
   • discovery_summary: bounded targets and purpose, never raw commands or reasoning.
   • level_started / level_completed, ac_routing, harness_changed, and ac_verified: report only meaningful transitions. Say "currently running with" because routes can escalate.
   • attention_required: surface immediately and follow the verified menu.
   • Synapse queued/delivering is not application; applied/completed is runtime-proven and may contain a bounded AC reply.

   Phrase the English canonical guidance naturally in the user's current conversation language.

   Do not paste the full raw tool output unless the user asks for raw status. Do not add speculative ETA unless the tool provides one.

   Synapse intent refinement: For additive user intent during a live run, reload deferred schemas with tool discovery query: "+ouroboros session signal", call ouroboros_session_signal_targets with the observed execution_id, and semantically match the user's meaning to ac_content and current activity. Never ask the user for internal IDs. Use the selected exact target with ouroboros_session_signal(mode="redirect", fallback_mode="after_turn", contract_effect="additive", source="user"), copying the exact execution, scope, attempt, and contract-version guards plus a stable idempotency key. Use mode="inform" for a read-only AC question or assurance request, omit fallback_mode entirely in that mode, and relay the bounded completed reply. Ask only when multiple candidates remain genuinely tied. Distinguish durable queued from runtime-proven applied/completed, never change the approved Seed contract, and render delivery state in the user's conversation language.

   For attention_required, use at most one short-lived read-only verifier. Without a verifier primitive, surface the evidence and do not ACT. Otherwise VERIFY → DECIDE from recommended_host_actions → LOG selected with ouroboros_record_conductor_decision → ACT only a menu-listed registered tool → LOG completed, failed, or declined. Run-mode specification changes require explicit user approval and a shared successor contract; never inject them into one live AC.

7. Use ouroboros_ac_tree_hud only for manual drill-down or anomaly checks.

   Do not call full tree HUD in the normal polling loop.

   Use these targeted calls:

   # Explicit short HUD, useful for a one-off check
   Tool: ouroboros_ac_tree_hud
   Arguments:
     session_id: <session_id>
     cursor: <cursor>
     view: "summary"
   
   # Lowest-token one-line HUD
   Tool: ouroboros_ac_tree_hud
   Arguments:
     session_id: <session_id>
     cursor: <cursor>
     view: "compact"
   
   # Full tree only when user asks "show details", progress looks stuck,
   # or debugging requires seeing the task/subtask structure.
   Tool: ouroboros_ac_tree_hud
   Arguments:
     session_id: <session_id>
     cursor: <cursor>
     view: "tree"
     max_nodes: 30

   Treat unchanged cursor=<cursor> from explicit compact/summary views as a no-op. Do not explain it to the user unless they explicitly asked for heartbeat messages.

8. Fetch final result with ouroboros_job_result:

   Tool: ouroboros_job_result
   Arguments:
     job_id: <job_id>

9. Present the execution results to the user:

   • Show success/failure status
   • Show session ID (for later status checks)
   • Show execution summary

10. Post-execution QA (automatic): ouroboros_start_execute_seed automatically runs QA after successful execution. The QA verdict is included in the final job result text. To skip: pass skip_qa: true to the tool.

Present QA verdict with next step:

• PASS: Next: ooo evaluate <session_id> for formal 3-stage verification
• REVISE: Show differences/suggestions, then Next: Fix the issues above, then ooo run to retry -- or ooo unstuck if blocked
• FAIL/ESCALATE: Next: Review failures above, then ooo run to retry -- or ooo unstuck if blocked

Fallback (No MCP Server)

If the MCP server is not available, inform the user:

Ouroboros MCP server is not configured.
To enable full execution mode, run: /ouroboros:setup

Without MCP, you can still:
- Use /ouroboros:interview for requirement clarification
- Use /ouroboros:seed to generate specifications
- Manually implement the seed specification
