Spike: AI-guided Git exercises

[braboj]

Summary

Evaluate how to build portable AI skills that deliver guided Git exercises (setup, task, verification) inside any AI chat — Claude CLI, Claude web, ChatGPT.

The AI is the tutor, not the sandbox. The learner uses real Git in a real terminal. The AI sets up the repo state, presents the task, gives hints, and verifies the result.

Deliverables

• Core skill prompt (skill.md) — exercise runner logic for both CLI (full automation) and web chats (guided mode)
• 3 starter exercises: first-commit, branching-basics, merge-conflict
• Validate portability across Claude CLI, Claude web, ChatGPT
• Publish as a public repo

Key decisions

1. Exercise state verification in web-only chats (learner pastes output)
2. Exercise sequencing — strict vs. free-form
3. Where exercises live — standalone repo or inside tutorial-git
