Fast-capture entrypoint for turning a workflow just performed in this conversation into a skill. Reads back over the recent turns, drafts a lite SKILL.md (trigger description + steps + edge cases), and confirms with the user before writing anything. Hands off to skill-creator for the full interview/eval/benchmark loop only when the pattern warrants that investment. Use when the user says "skillify this," "capture this pattern," "turn this into a skill," "make this repeatable," or similar — this is the terse trigger for a two-minute capture, not the heavyweight skill-creator interview.
