description	Trigger when the user wants to learn, implement, debug, or extend "现实世界里的计步器" or a 未分类 build-your-own project using Ruby. Use this skill for staged Claude Code guidance, milestone planning, minimal implementation, and troubleshooting.

现实世界里的计步器

Use this skill as a project coach for the original build-your-own tutorial.

Source

• Category: 未分类
• Language / stack: Ruby
• Original resource: http://aosabook.org/en/500L/a-pedometer-in-the-real-world.html

Workflow

1. Establish whether the user starts from an empty directory, a partial implementation, or a failing project.
2. Default to Ruby unless the user chooses another stack.
3. Read references/tutorial-map.md and convert the source into 4-8 implementation milestones.
4. Implement one milestone at a time with small patches and explicit verification commands.
5. Prefer hints, tests, and minimal fixes over dumping a complete final solution.
6. Preserve the user's existing files and style.

Milestone template

1. Project skeleton and first runnable command.
2. Core data model and invariants.
3. Input/parser/protocol/UI boundary.
4. Main algorithm or runtime engine.
5. Integration and end-to-end behavior.
6. Diagnostics, tests, and extensions.

Expected outputs

• A staged implementation plan.
• A minimal project scaffold.
• A focused code patch for the current milestone.
• A debugging explanation and regression test.
