# /ultracook (retired)

`/ultracook` is retired as a top-level skill. Its mechanics — decompose, wave-fan curds, harvest, wire, post-merge review, plate — now live inside `/cook`'s single pathway, dispatched via `/cook --auto`, each phase still running as a fresh, isolated sub-agent context blind to the prior phase's reasoning. See [`../cook/SKILL.md`](../cook/SKILL.md)'s `## Fan pathway` section.

## Redirect

Any `/ultracook <spec> [flags]` invocation resolves to `/cook <spec> [flags]`. Carry `--open-pr`, `--resume <slug>`, and `--auto` forward verbatim — their semantics are unchanged, just hosted inside `/cook` now.

## What did not move

- `skills/ultracook/references/` remains as compatibility material for `/cook`'s fan pathway; executable runtime now ships only in `cook.pyz`, and no `ultracook.pyz` bundle is published.
- The manifest path stays `.cheese/ultracook/<slug>/manifest.yaml` for continuity — the identity of the skill that reads/writes it changed, not the path; its shape is `references/manifest-schema.json`, and each curd's dispatch prompt is `references/curd-prompt.md`, both read by `/cook`'s fan pathway.
- `src/easy_cheese/shared/fanout/mode.py` remains a decomposer/fanout internal — `/cook`'s fan pathway calls it directly rather than through this retired skill.
- The retained scripts/references still do source-code I/O under `/cook`'s ownership — that follows [`code-intelligence-routing.md`](../cheese/references/code-intelligence-routing.md) same as everywhere else.

If you are here because muscle memory typed `/ultracook`, run `/cook` with the same arguments.
