type:review
A model-selection cost policy for Claude Code — route bulk, mechanical work to cheaper/faster models and reserve frontier models for judgment and review. Covers the cost/quality tradeoff, a decision matrix, how to switch models per task and per subagent, and orchestration patterns that minimize total cost to a correct result. Use when deciding which model to run or how to control spend.

From the source SKILL.md

The core idea: match the model to the marginal value of its judgment. Frontier models are worth their cost where a better decision changes the outcome. For high-volume mechanical work whose correctness is easy to check, a cheaper, faster model gets you the same result for a fraction of the cost.

What this skill does

Cost Controller is a community-contributed Claude Code skill in the agents-skills-meta sub-category. It ships as a SKILL.md file that Claude Code auto-discovers under ~/.claude/skills/cost-controller/ and loads when your prompt matches the skill's trigger.

When to invoke it: Use when deciding which model to run or how to control spend.
