Directory Structure

The tool expects the following directory structure in your git repository:

your-repo/
├── agentrules/
│   ├── shared/             # Shared rules for all assistants
│   ├── cursor/             # Cursor-specific rules
│   ├── windsurf/           # Windsurf-specific rules
│   ├── claude-code/        # Claude Code-specific rules
│   ├── chatgpt-codex/      # ChatGPT Codex-specific rules
│   └── review-guidelines/  # Review guidelines (optional)

Generated Files

The tool generates the following files in your repository root:

• .cursor/rules/*.gen.mdc - Cursor rules files (with YAML frontmatter)
• .cursor/BUGBOT.md - Cursor Bugbot review guidelines (from review-guidelines/, as-is)
• .windsurfrules - Windsurf rules file
• CLAUDE.md - Claude Code rules file
• AGENTS.md - ChatGPT Codex rules file (includes ## Review guidelines section if present)

How It Works

1. Finds the git repository root from the current working directory
2. Reads markdown files from agentrules/ subdirectories
3. Generates formatted output files for each AI assistant:
   • Cursor: adds YAML frontmatter if not present
   • Windsurf/Claude/Codex: strips YAML frontmatter and first headings
4. If review-guidelines/ exists:
   • Appends processed content to AGENTS.md under ## Review guidelines
   • Generates .cursor/BUGBOT.md with raw content (no processing)
