description: Never launch parent or Task/subagent work in Fast mode

alwaysApply: true

---

# No Fast mode

Canonical policy: `~/.cursor/rules/no-fast-mode.mdc`. Follow that file. Restated here so workspace agents cannot miss it.

Never use Fast effort/mode for any model family — parent session or any Task/subagent (nested, Multitask, background, review ladders, explore, cloud).

Forbidden slugs (non-exhaustive): `*-fast*`, `composer-2.5-fast`, `grok-4.5-fast*`, `grok-4.6-fast*`, `cursor-grok-4.6-*-fast`, GPT Fast, Claude Fast.

- Substitute non-Fast Medium (or the required non-Fast family). Default Task model: `cursor-grok-4.6-medium`; if the host rejects medium, use the closest available non-Fast Grok 4.6 slug. Never fall back to Fast. Do not remap RFL GPT/Claude/OpenCode (or visual Gemini) work to Grok Medium.

+ Substitute non-Fast High (or the required non-Fast family). Default Task model: `cursor-grok-4.6-high`; if the host rejects High, use the closest available **non-Fast, non-XHigh** Grok 4.6 slug. Never fall back to Fast or Extra High. Do not remap RFL GPT/Claude/OpenCode (or visual Gemini) work to Grok High.

```

❌ BAD — Task model: composer-2.5-fast or grok-4.6-fast*

- ✅ GOOD — Task model: cursor-grok-4.6-medium (or closest non-Fast Grok 4.6 if medium rejected)

+ ✅ GOOD — Task model: cursor-grok-4.6-high (or closest non-Fast, non-XHigh Grok 4.6 if High rejected)

```

The user may change model family. Fast stays forbidden unless they explicitly say Fast.
