claude-whetstone

Run one "turn of the crank" on a target skill, prompt, or piece of guidance. Apply the skill to a real test input, self-grade against its own rules, improve the output, then surface ambiguities to the user as A/B questions and fold the answers back into the skill file. The skill is the durable artifact; the chat is exhaust. Use when the user says "run the whetstone loop", "sharpen this skill", "improve this prompt", "turn the crank on X", or wants to compound learnings into a versioned skill instead of re-prompting one-off.
