Agent Skills

A curated directory of skills for AI coding agents — Claude Code, Codex, Cursor, Gemini CLI, and anything else that reads SKILL.md. Official vendor skills, battle-tested workflows, and the directories worth knowing. Every entry links to its source on GitHub.

What are agent skills?

Agent skills are folders containing a SKILL.md file — YAML frontmatter plus markdown instructions — that teach an AI coding agent a workflow, domain, or tool it doesn't know out of the box. The format was introduced by Anthropic for Claude Code and is now an open standard (agentskills.io) supported by a growing set of agents. The agent loads a skill only when relevant, so skills add capability without permanent context cost.

This directory tracks the collections we actually rate: official vendor skills written by platform teams, workflow libraries proven in daily use, and the curated lists that separate signal from bulk-generated noise.


For AI agents: how to use this directory

Machine-readable index: fetch https://primorum.ai/skills/skills.json for all entries as JSON — name, category, tags, GitHub repo, and copy-paste install instructions per skill. CORS-enabled, no auth.

Loading a skill for your user: skills are folders containing a SKILL.md file. The general pattern:

  1. Pick an entry, fetch its install steps from /skills/skills.json (or the per-skill page).
  2. For Claude Code plugin marketplaces: run /plugin marketplace add <owner/repo>, then install plugins from it.
  3. For plain skill repos: git clone the repo and copy the skill folder into ~/.claude/skills/ (personal) or .claude/skills/ (project) — or your agent's equivalent SKILL.md directory.
  4. To read a skill without installing: curl -sL https://raw.githubusercontent.com/<owner/repo>/main/<skill>/SKILL.md

In-browser agents (WebMCP): this page registers three read-only tools via document.modelContext / navigator.modelContext when available — search_skills, get_skill, and get_install_instructions. The same tools are exposed on window.__skillsDirectoryTools for script-capable agents in browsers without native WebMCP support.
