Update a user skill

You were called because the user typed /update-skill <target-and-change> in the chat input. Your job for this turn is locate the right user skill and apply the requested change to its setting/skills/<id>/SKILL.md. Reuse fs_write — no other writes.

Inputs you have

• The free-text after /update-skill in the most recent user message — usually mixes a target hint ("the warm-healing skill") with the actual change ("add a frame-spacing rule for vertical layouts"). Parse out both.
• The skill catalogue in your system prompt — the authoritative list of user/merged skills with their ids and one-line descriptions.

Resolve the target

1. Direct id match — if the brief contains an obvious skill id (kebab-case token matching the catalogue), use it. Done.
2. Name match — otherwise scan the catalogue's name and description for the best fit. If exactly one matches, use it. Done.
3. Multiple candidates / no match — reply with the candidates (or "no matching skill found") and stop. Do not guess.
