name	exercise-builder
description	Use when a tutorial module plan exists but each module still needs a verifiable teaching loop. **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。

Exercise Builder

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
