CreatorSkills for Developers
Skills are plain SKILL.md / .mdc files — drop them where your tool reads system prompts.
Manual install
Skills download as either a single SKILL.md file or a ZIP containing multiple .md files. Place them where your tool expects system prompt files.
Place the skill file in your Claude skills directory:
~/.claude/skills/my-skill/SKILL.mdOr reference it directly in your project configuration.
Download the .mdc file and place it in your project rules directory:
.cursor/rules/my-skill.mdcCursor picks up rules automatically from this directory.
The SKILL.md Format
Skills are plain markdown files with structured instructions. No proprietary format — they work anywhere that accepts system prompts. Single-file skills are just SKILL.md. Multi-file skills ship as a ZIP:
skills/my-skill/
├── SKILL.md # Main skill instructions
├── README.md # Setup guide & tips
├── EXAMPLE.md # Worked examples
└── TEMPLATES.md # Optional templatesSKILL.mdThe core system prompt. This is what gets loaded into your AI tool.
README.mdSetup instructions, configuration options, and usage tips.
