Generate Commit Message

Analyze the current staged changes, recent commit style, and project context to craft a commit message that accurately describes what was done and why.

Steps

1. Gather context

``bash git status --short git diff --staged --stat git diff --staged --name-only git log --oneline -10 ``

1. Read key changed files (optional but helpful)

• For new files: read them to understand their purpose
• For significant modifications: read the diff or the file

1. Load project context

``bash ls -1 .context/ | sort ` Read the most recent .context/` files, up to 6, to understand recent work and decisions.

1. Analyze and synthesize

• Group changes into logical themes (e.g., "dev workflow", "new feature", "refactor", "bugfix")
• Identify the primary change that defines the commit
• Note secondary changes that support it
• Check if there are any "hidden" fixes (e.g., proxy bug, HMR preamble) that aren't obvious from filenames

1. Draft the message

• Use Conventional Commits format: type(scope?): subject
• type: feat, fix, refactor, docs, test, chore, build
• Keep subject line under 72 characters
• Add a blank line, then bullet points for significant details
• Each bullet should answer what and why, not just what
• Reference context files or decisions when relevant (e.g., "per golang-react-islands-spec")

1. Present to user

Show the full message in a code block. Ask: > "Does this look right? Say 'commit' to stage it, or tell me what to change."

Rules

• Do NOT commit automatically — always wait for explicit user confirmation.
• If there are unrelated changes mixed together, warn the user and suggest splitting.
• Match the style of recent commits (check git log --oneline).
• If .context/ exists, use it — it contains the "why" behind the changes. If it does not exist, create it.
• For delete operations, mention what was removed and why.
• For new files, mention their purpose, not just their names.
• Keep bullet points parallel in structure (start with verb, same tense).

Example Output

feat: add CategoryPills island, Button component, and dev workflow fixes
 
- Replace inline vanilla JS category fetch with React CategoryPills island
  hydrated on expense add/edit forms
- Add reusable Button.tsx component with 6 variants (primary, secondary,
  neutral, ghost, danger, pill)
- Add templates/partials/button.html Go partial kept in sync with Button.tsx
- Convert all template buttons to use the shared partial
- Makefile: `make dev` now starts both Go and Vite servers in one command
- Fix Vite dev proxy to bypass Vite internals via `bypass()` function
- Add React Refresh preamble to DevClient for HMR support
- Fix AssetHelper.ScriptTag to match manifest entries by Name or Src path
