ooo evolve - Evolutionary Loop
Description
Start, monitor, or rewind an evolutionary development loop. The loop iteratively
refines the ontology and acceptance criteria across generations until convergence.
Flow
Gen 1: Interview → Seed(O₁) → Execute → Evaluate
Gen 2: Wonder → Reflect → Seed(O₂) → Execute → Evaluate
Gen 3: Wonder → Reflect → Seed(O₃) → Execute → Evaluate
...until ontology converges (similarity ≥ 0.95) or max 30 generations
Usage
Start a new evolutionary loop
ooo evolve "build a task management CLI"
Fast mode (ontology-only, no execution)
ooo evolve "build a task management CLI" --no-execute
Check lineage status
ooo evolve --status <lineage_id>
Rewind to a previous generation
ooo evolve --rewind <lineage_id> <generation_number>
Instructions
Load MCP Tools (Required before Path A/B decision)
The Ouroboros MCP tools are often registered as deferred tools that must be explicitly loaded before use. You MUST perform this step before deciding between Path A and Path B.
- Use the active runtime's tool-discovery capability to find and load the evolve MCP tools:
tool discovery query: "+ouroboros evolve"
- The tools will typically be named with prefix
mcp__plugin_ouroboros_ouroboros__ (e.g., ouroboros_evolve_step, ouroboros_interview, ouroboros_generate_seed). After runtime tool discovery returns, the tools become callable.
- If the tools are callable — already exposed, or loaded by discovery — proceed to Path A. An empty discovery result for already-exposed tools is expected, not a failure. Proceed to Path B 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 ouroboros_* 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 ouroboros_* MCP tool
while its schema is not loaded in the current turn, the runtime rejects the
call with "Invalid tool parameters" before it ever reaches the server.
Therefore: immediately before EVERY ouroboros_* MCP call in this skill, re-run
the tool-discovery load query for the specific MCP tool or documented tool family
you are about to call. Use "+ouroboros evolve" for ouroboros_evolve_step,
ouroboros_lineage_status, and the evolve flow's documented tool family;
use "+ouroboros interview" before ouroboros_interview, "+ouroboros seed"
before ouroboros_generate_seed, and "+ouroboros lateral" before
ouroboros_lateral_think. If a 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 / Path B instead of retrying the failing call.
Path A: MCP Available (loaded via runtime tool discovery above)
Starting a new evolutionary loop:
- Parse the user's input as
initial_context
- Run the interview: call
ouroboros_interview with initial_context
- Complete the interview (3+ rounds until ambiguity ≤ 0.2)
- Generate seed: call
ouroboros_generate_seed with the session_id
- Call
ouroboros_evolve_step with:
lineage_id: new unique ID (e.g., lin_<seed_id>)
seed_content: the generated seed YAML
execute: true (default) for full Execute→Evaluate pipeline,
false for fast ontology-only evolution (no seed execution)
- Check the
action in the response:
continue → Call ouroboros_evolve_step again with just lineage_id
converged → Evolution complete! Display final ontology
stagnated → Ontology unchanged for 3+ gens. Consider ouroboros_lateral_think
exhausted → Max 30 generations reached. Display best result
failed → Check error, possibly retry
- Repeat step 6 until action ≠
continue
- When the loop terminates, display a result summary with next step:
converged: 📍 Next: Ontology converged! Run ooo evaluate for formal verification
stagnated: 📍 Next: ooo unstuck to break through, then ooo evolve --status <lineage_id> to resume
exhausted: 📍 Next: ooo evaluate to check best result — or ooo unstuck to try a new approach
failed: 📍 Next: Check the error above. ooo status to inspect session, or ooo unstuck if blocked
Checking status:
- Call
ouroboros_lineage_status with the lineage_id
- Display: generation count, ontology evolution, convergence progress
Rewinding:
- Call
ouroboros_evolve_step with:
lineage_id: the lineage to continue from a rewind point
seed_content: the seed YAML from the target generation
(Future: dedicated ouroboros_evolve_rewind tool)
Path B: Plugin-only (no MCP tools available)
If MCP tools are not available, explain the evolutionary loop concept and
suggest installing the Ouroboros MCP server. See Getting Started for install options, then run:
ouroboros mcp serve
Then add to your runtime's MCP configuration (e.g., ~/.claude/mcp.json for Claude Code).
Key Concepts
- Wonder: "What do we still not know?" - examines evaluation results
to identify ontological gaps and hidden assumptions
- Reflect: "How should the ontology evolve?" - proposes specific
mutations to fields, acceptance criteria, and constraints
- Convergence: Loop stops when ontology similarity ≥ 0.95 between
consecutive generations, or after 30 generations max
- Rewind: Each generation is a snapshot. You can rewind to any
generation and branch evolution from there
- evolve_step: Runs exactly ONE generation per call. Designed for
Ralph integration — state is fully reconstructed from events between calls
- execute flag:
true (default) runs full Execute→Evaluate each generation.
false skips execution for fast ontology exploration. Previous generation's
execution output is fed into Wonder/Reflect for informed evolution
- QA verdict: Each generation's response includes a QA Verdict section
(when
execute=true and skip_qa is not set). Use the QA score to track
quality progression across generations. Pass skip_qa: true to disable
