Works with: Claude Code · OpenAI Codex · Gemini CLI · OpenClaw · Hermes Agent[^hermes] · Mistral Vibe[^vibe] · Cursor · Aider · Windsurf · Kilo Code · OpenCode · Augment · Antigravity

[^hermes]: Hermes Agent is BYO-sync tier: the repo ships a pre-generated .hermes/skills/claude-skills/ tree (305 skills across 12 domains as of v2.7.3), but you run python scripts/sync-hermes-skills.py once locally to install into ~/.hermes/skills/. Uses the same agentskills.io SKILL.md standard — no format conversion. [^vibe]: Mistral Vibe is also BYO-sync tier: the repo ships a pre-generated .vibe/skills/claude-skills/ tree (306 skills across 14 domains), run ./scripts/vibe-install.sh once locally to install into ~/.vibe/skills/. Same agentskills.io SKILL.md standard — no format conversion. Docs: https://docs.mistral.ai/mistral-vibe/agents-skills.

5,200+ GitHub stars — the most comprehensive open-source Claude Code skills & agent plugins library.

What Are Claude Code Skills & Agent Plugins?

Claude Code skills (also called agent skills or coding agent plugins) are modular instruction packages that give AI coding agents domain expertise they don't have out of the box. Each skill includes:

• SKILL.md — structured instructions, workflows, and decision frameworks
• Python tools — ~402 CLI scripts (all stdlib-only, zero pip installs)
• Reference docs — templates, checklists, and domain-specific knowledge

One repo, twelve platforms. Works natively as Claude Code plugins, Codex agent skills, Gemini CLI skills, Hermes Agent skills, Mistral Vibe skills, and converts to 7 more tools via scripts/convert.sh. All ~402 Python tools run anywhere Python runs.

Skills vs Agents vs Personas

| | Skills | Agents | Personas | |---|---|---|---| | Purpose | How to execute a task | What task to do | Who is thinking | | Scope | Single domain | Single domain | Cross-domain | | Voice | Neutral | Professional | Personality-driven | | Example | "Follow these steps for SEO" | "Run a security audit" | "Think like a startup CTO" |

All three work together. See Orchestration for how to combine them.

Multi-Tool Support (New)

Convert all 156 skills to 7 AI coding tools with a single script:

| Tool | Format | Install | |------|--------|---------| | Cursor | .mdc rules | ./scripts/install.sh --tool cursor --target . | | Aider | CONVENTIONS.md | ./scripts/install.sh --tool aider --target . | | Kilo Code | .kilocode/rules/ | ./scripts/install.sh --tool kilocode --target . | | Windsurf | .windsurf/skills/ | ./scripts/install.sh --tool windsurf --target . | | OpenCode | .opencode/skills/ | ./scripts/install.sh --tool opencode --target . | | Augment | .augment/rules/ | ./scripts/install.sh --tool augment --target . | | Antigravity | ~/.gemini/antigravity/skills/ | ./scripts/install.sh --tool antigravity | | Hermes Agent | ~/.hermes/skills/ | python scripts/sync-hermes-skills.py --verbose | | Mistral Vibe | ~/.vibe/skills/ | ./scripts/vibe-install.sh |

How it works:

# 1. Convert all skills to all tools (takes ~15 seconds)
./scripts/convert.sh --tool all

# 2. Install into your project (with confirmation)
./scripts/install.sh --tool cursor --target /path/to/project

# Or use --force to skip confirmation:
./scripts/install.sh --tool aider --target . --force

# 3. Verify
find .cursor/rules -name "*.mdc" | wc -l  # Should show 156

Each tool gets:

• ✅ All 156 skills converted to native format
• ✅ Per-tool README with install/verify/update steps
• ✅ Support for scripts, references, templates where applicable
• ✅ Zero manual conversion work

Run ./scripts/convert.sh --tool all to generate tool-specific outputs locally.
