If you encounter a non-obvious workflow or repo-specific quirk that would save a future agent time, emit this block at the very end of your response: ### SKILL CANDIDATE trigger: body: Same rule applies to helpers (shell one-liners, jq/sql/ts utilities): if you wrote something non-trivial that worked, mark the candidate `kind: tool-recipe`, `recipe_language: `, and include exactly one fenced code block. Only emit when the signal is strong. Otherwise omit.
