What it tells the agent
Full source on GitHub ↗Its description: Use when a tutorial module plan exists but each module still needs a verifiable teaching loop.
--- name: exercise-builder description: "Use when a tutorial module plan exists but each module still needs a verifiable teaching loop." --- # Exercise Builder ## Triggers & routing - **Trigger**: exercises, practice, verification checklist, 教程练习, 可验证作业. - **Use when**: tutorial 的 C2,已有 `outline/module_plan.yml`,需要为每个模块补齐 exercise / expected output / verification steps。 - **Skip if**: 还没有 module plan。 - **Network**: none. - **Guardrail**: 练习必须可验证,不能只给开放式思考题。 Adds the minimal deterministic exercise contract to each planned tutorial module. ## Input - `outline/module_plan.yml` ## Output - updated `outline/module_plan.yml` ## Contract Each module must end up with at least one `exercise` containing: - `prompt` - `expected_output` - `verification_steps` ## Script boundary `scripts/run.py` should: - load the current module plan - fill missing exercises deterministically - write the plan back in place Keep exercise phrasing logic in shared tutorial tooling rather than hardcoding it repeatedly in the skill script. ## Acceptance - every module has `exercises` - every exercise includes `expected_output` - every exercise includes `verification_steps` ## Non-goals - source coverage auditing - prose tutorial writing
