Individual skill
evaluate
Use when the user wants proof that finished work meets its acceptance criteria, not just that tests pass: 'verify it is actually done', 'check it against the spec', 'evaluate the run'. Runs mechanical checks, a semantic review per criterion, and multi-model consensus when uncertain. With execution.auto_evolve on (the default), a rejected result with a Seed continues into a Ralph fix loop; pass auto_evolve: false to verify only.

# /ouroboros:evaluate
Evaluate an execution session with the three-stage verification pipeline.
```
/ouroboros:evaluate <session_id> [artifact]
```
## Stage authority
1. **Mechanical** (lint, build, test, static analysis, coverage; no model cost): the only stage that can grant approval. At least one configured check must run and all must pass.
2. **Semantic** (AC compliance, goal alignment, drift): advisory. Can withhold approval and give feedback; cannot grant it.
3. **Consensus** (multi-model, only on uncertainty or request): advisory. A rejection withholds approval; an approval cannot grant it or lift a Stage 2 block.
