Maintenance, license and trust

  • The repository was last updated about 10 months ago. That is recent enough to be usable, but agent tooling moves fast, so check the instructions against your agent's current version.
  • Our last check on 2026-10-21 found the source still online.
  • It is released under GPL-3.0, a copyleft license: you can use it, but modified versions you distribute must carry the same license.
  • Its trust signals score 94/100, with 1 caution from licensing, adoption, age or documentation. These come from repository metadata, not a code audit — read the skill file before letting an agent act on it.

Safety scan

Usage

  1. Installation

    • Clone this repository into your project's root directory
    • Ensure the .cursor/rules directory structure is maintained
  2. Rule Application

    • Rules are automatically applied based on file patterns (globs)
    • Rules in higher-level directories (e.g., security/) take precedence
    • Each rule file (.mdc) contains metadata for scope and priority
  3. Development Workflow

    • Follow the patterns and examples in each rule file
    • Use the provided validation rules for code quality
    • Implement security considerations as specified

Contributing

  1. Adding New Rules

    • Place rules in appropriate category directory
    • Use .mdc extension for rule files
    • Include proper metadata (description, globs, priority)
    • Provide clear examples and anti-patterns
  2. Modifying Rules

    • Maintain backward compatibility
    • Update dependencies appropriately
    • Document changes in commit messages

File Format

Each .mdc file follows this structure:

---
description: Brief description of the rule's purpose
globs: ["pattern/to/match/*.{ts,js}"]
priority: numeric_priority
dependencies: ["other.mdc"]
