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
