About awesome-agent-skills
heilcheng/awesome-agent-skills
A curated list of skills, tools, tutorials, and capabilities for AI coding agents (Claude, Codex, Antigravity, Copilot, VS Code)
Organizes skills as lazy-loaded instruction files (`SKILL.md`) that AI agents browse, request, and execute on-demand—reducing memory overhead while supporting multiple agent platforms (Claude, Copilot, Codex, Gemini). Aggregates official skill collections from Anthropic, OpenAI, and HuggingFace alongside community-maintained repositories covering document processing, development tools, and domain-specific capabilities. Skills work across agents and delivery mechanisms including CLI installers, MCP, and package managers.
