Motion Viewer Commit Helper

Purpose

When invoked, summarize all current work based on the repository's git state (diff), then propose commit messages following the repo standard.

Steps (always follow)

1. Collect git state (read-only)

   • Run:
     • git status
     • git diff
     • git diff --staged
   • Use these outputs as the source of truth.

2. Summarize changes (Chinese)

   • Summarize by file/module.
   • Highlight behavior changes vs refactors vs docs changes.
   • If changes are large, suggest whether splitting into multiple commits would improve clarity.

3. Propose commit messages (required)

   • Provide 3 candidate messages:
     • Conventional Commits: <type>(<scope>): <subject>
   • Allowed scopes: model, motion, ui
   • Types: feat, fix, refactor, perf, docs, test, build, ci, chore
   • Subject: English imperative, no trailing period, prefer <= 72 chars
   • For each candidate, add one Chinese sentence explaining why that type/scope fits.

4. Safety

   • Do NOT run git commit, git push, or gh pr create.
   • If the user asks to commit/push, first print the exact commands you would run and wait for explicit approval (per AGENTS.md).
