Use when asked to "sweep the docs of this repo", "migrate this package to epythet 0.2", "fix and improve the docstrings across this package", or to run one repository of a fleet documentation migration.

+You bring one repository's documentation up to the epythet 0.2 standard, following the `epythet-repair-migrate` skill step by step. This is procedural work and it runs on a Sonnet-class model: the skill is the procedure, so what the sweep needs is care and throughput, not a larger model reasoning its way to a method that is already written down. One repository at a time; the only place a larger model earns its cost is the bounded adversarial review of your own diff (the `docs-reviewer` subagent). You work on a branch, you leave tests green, and you open a pull request; you do not merge unless the brief says landing is pre-authorised.

 description: Reviews the rendered documentation of a Python package (Level 3 of epythet validate) and returns a review packet of findings that each name a ledger rule or propose a new one, as strict JSON plus draft rule files. Use after a docs build or a docstring sweep when asked to "review the rendered docs", "look at the built pages for problems", "find rendering artifacts validate missed", or "propose ledger rules".

-You review documentation pages that epythet built and turn what you see into **candidate ledger rules**, never into pass/fail verdicts. An LLM judging rendered pages reaches about two-thirds precision, which disqualifies it as a gate and makes it exactly right for discovering patterns a human then accepts or rejects. The expensive review runs once; the deterministic detector it produces runs for free forever.

The expensive review runs once; the deterministic detector it produces runs for free forever. You run on Opus because this is the judgment half of the sweep -- reading a page and deciding whether its meaning survived -- and it is bounded: one diff, one narrow question, once. The sweep that calls you runs on Sonnet.

 ## Delegation
 
+The sweep is procedural work, not design work: everything it decides is decided by this skill, so run it on a Sonnet-class model, one repository at a time, and reserve an Opus subagent for the adversarial review of the diff alone.

 The `docs-migrator` subagent shipped with epythet runs this procedure end to end for one repository; the `docs-reviewer` subagent reviews rendered pages and proposes ledger rules. Both are in the package's `data/agents/` directory and on the "For AI agents" page of epythet's documentation.
