Git installed and configured
API key for your chosen LLM provider (OpenAI, Claude, or Gemini)

Run the command git-mew: Setup Model to configure your AI provider

Customizing Rules

Git Mew allows you to customize how AI generates content by creating rule files in a .gitmew folder in your repository root.

Customizing Commit Message Rules

Create a file: .gitmew/systemprompt.generate-commit.md
Define your custom commit message rules in this file. The AI will use these instructions instead of the default prompt.

Customizing Code Review Rules

You can customize the code review process at two levels:

Custom System Prompt: To completely replace the default review instructions, create .gitmew/systemprompt.review-merge.md. This file gives you full control over the AI's persona, structure, and output format.
Custom Review Rules: To add specific, project-level rules on top of the default system prompt, create .gitmew/code-review-rule.md. This is useful for defining project-specific conventions, style guides, or areas to check.

Example structure:

your-project/
├── .gitmew/
│   ├── systemprompt.generate-commit.md  # Custom rules for commit messages
│   ├── systemprompt.review-merge.md     # (Optional) Overrides default review prompt
│   └── code-review-rule.md              # (Optional) Adds specific rules to the review
├── src/
└── ...
