Other agents

To use these skills with another agent (like AntiGravity or Gemini CLI):

1. Ingest: The agent reads the skills directory.
2. Activate: Each skill contains a SKILL.md defining when and how it should be used.
3. Execute: The agent follows the structured workflows and patterns defined in the skill files.

🛠️ Contributing

1. Create a new directory in skills/.
2. Add a SKILL.md with the required frontmatter.
3. Include any necessary scripts or resources.
