Our review
Manages reusable, parameterized prompts (skills) for AI agents through a command-line interface.
Strengths
- Enables structured prompts with metadata and arguments
- Automatic validation of SKILL.md file format
- Ability to schedule recurring tasks using these skills
- Searches local and global skill directories
Limitations
- Requires installation of the codegeass tool
- Only works with agents that support the skill format (e.g., Claude Code)
- Limited documentation on advanced argument formats
When you need standardized, reusable prompts for common tasks like code review.
For ad-hoc interactions or highly specific prompts that don't benefit from reusability.
