AI-assisted commit message generation

[jordanpartridge]

Overview

Use local LLM (Ollama) or cloud AI to generate commit messages from diffs.

Commands

commit ai

commit ai                       # Generate message from staged diff
commit ai --model llama3       # Use specific model
commit ai --style conventional # Enforce conventional commits
commit ai --verbose            # Include reasoning

commit suggest

commit suggest                  # Show 3 message options
commit suggest --pick 2        # Use option 2

Implementation

Local LLM (Ollama)

// Use Ollama for privacy/speed
$response = Http::post('http://localhost:11434/api/generate', [
    'model' => 'llama3',
    'prompt' => $this->buildPrompt($diff),
]);

Prompt Template

Analyze this git diff and generate a conventional commit message.

Rules:
- Use format: type(scope): description
- Types: feat, fix, docs, refactor, test, chore
- Keep description under 50 chars
- Focus on WHY not WHAT

Diff:
{diff}

Commit message:

Fallback

• If Ollama not running, offer cloud option
• Cache common patterns for speed

Configuration

commit config --ai-model llama3
commit config --ai-provider ollama
commit config --ai-style conventional
