/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/easycheese/shared/fanout/mode.py and src/easycheese/shared/fanout/curd_block.py remain decomposer/fanout internals — /cook's fan pathway calls them 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.
