gitMessageGenerator

AI-powered git commit messages via Chutes.ai, OpenCode Zen, or OpenCode Go — one click in Source Control.

Requires an API key. This extension does not provide free access — you must bring your own key from one of the supported providers. Usage, billing, and data handling are between you and the respective provider. This extension never stores, logs, or transmits your API keys except directly to the provider's API endpoint.

Stage your changes, hit the sparkle button, get a well-crafted commit message. Supports Conventional Commits, imperative style, or your own custom format.

Providers

Pick one via gitMessageGenerator.provider. Change anytime.

All three use Bearer auth. Zen and Go share the same API key.

Quick Start

1. Install the extension (see Installation)
2. Pick a provider in settings: chutes, opencode-zen, or opencode-go
3. Set your API key in settings:
   • Chutes: gitMessageGenerator.chutesApiKey (keys start with cpk_)
   • OpenCode: gitMessageGenerator.opencodeZenKey (get one at opencode.ai/auth)
4. Pick a model — required: Ctrl+Shift+P → gitMessageGenerator: Select Model → search and select
5. Stage changes with git add
6. Click the sparkle in the Source Control panel title bar

Features

• Three providers — Chutes.ai, OpenCode Zen, OpenCode Go — switch anytime
• Live model browser — searchable quick pick, per-provider model lists fetched in real-time
• Auto-fallback — if your model is unavailable, picks the next active one (configurable)
• Commit style selector — built-in Conventional Commits and imperative, or define unlimited custom styles
• Custom styles — named presets at global or workspace level for per-project defaults
• Settings auto-migration — copies legacy settings to new prefix on first activation
• Smart context — branch name, recent commits, staged diffs with file statuses
• Lock file filtering — skips package-lock.json, yarn.lock, and 15+ others
• Binary detection — handles binary files in diffs gracefully
• Regeneration — click again while text is in the input box for a new message
• Multi-repo support — prompts you to pick a repo in multi-root workspaces
• Cancellable progress — cancel anytime from the SCM panel
• Zero dependencies — uses Node.js built-ins only

Settings

All settings use the gitMessageGenerator prefix.

Commit styles

Built-in

Use Ctrl+Shift+P → gitMessageGenerator: Select Commit Style to switch, or set commitStyle directly.

Custom styles

Define your own in settings. Works at global or workspace scope for per-project defaults.

{
  "gitMessageGenerator.customStyles": {
    "jira": "You are a commit message generator. Prefix every commit with the JIRA ticket from the branch name. Format: ABC-123: description",
    "minimal": "Generate a single-line commit message in imperative mood. Max 50 characters. No prefixes, no explanation."
  }
}

Then set gitMessageGenerator.commitStyle to jira or minimal. Custom styles appear in the style picker.

Per-project example (.vscode/settings.json):

{
  "gitMessageGenerator.commitStyle": "jira",
  "gitMessageGenerator.customStyles": {
    "jira": "Prefix every commit with the JIRA ticket from the branch name. Format: ABC-123: description"
  }
}

The customPrompt setting overrides all style settings if set — use it for quick one-off overrides.

Commands

How it works

Stage changes → Click sparkle → Extension gathers git context
                                       │
                                       ▼
                              Sends to provider API
                              (Chutes / Zen / Go)
                                       │
                                       ▼
                              Cleans LLM response
                              (strips markdown, quotes)
                                       │
                                       ▼
                              Writes to commit input box
                                       │
                                       ▼
                              You review and commit

Context gathered per request:

• Current branch name
• Last 5 commit messages
• Staged file list with statuses (added/modified/deleted/renamed)
• Per-file diffs (lock files excluded, binaries detected, large diffs truncated at 4000 chars)

Auto-fallback: If the configured model returns "not found", the extension queries the provider for active models, picks the first available one, retries, and saves the new model. Disable via autoFallback: false.

Regeneration: If there's already text in the input box when you generate, the model is instructed to produce a completely different message.
