# $ccc-plan-exec — Plan Cheap, Execute Capable Plan-exec splits work into two phases on two models. A **cheap, fast model drafts the plan** — the step list, the loop body, the structure. Then a **capable model (Opus/Fable) executes each step**. You write a *loop*, not a one-shot prompt: the structure is decided once, cheaply, then run N times against the expensive reasoner only where reasoning earns its cost. **CC Commander** · Plan-Exec Mode · [Docs](https://commanderplugin.com) > Plan-exec is the canonical workflow-first doctrine (`commander/cowork-plugin/rules/workflow-first.md`) applied to *cost*: **let the cheap model decide the shape, let the capable model do the thinking.** Motto: "Pay for Fable on the thinking, not the typing." --- ## Write loops, not prompts A **prompt** is a one-shot: "do this whole thing." A **loop** is a structure plus a body that repeats: "for each item, do the body." The loop body is small, predictable, and capable-model-worthy. The structure around it — the item list, the order, the guards — is boring scaffolding a cheap model nails for cents. | | One-shot prompt | Loop (plan-exec) | |---|---|---| | Who plans | Capable model (wasteful) | Cheap/fast model | | Who executes | Capable model | Capable model, per step | | Cost shape | Pay expensive for scaffolding + thinking | Pay cheap for scaffolding, expensive only for thinking | | Failure mode | Whole run dies, re-pay everything | One step retries, rest survives | | Verifiability | Monolit
