[^hermes]: Hermes Agent is BYO-sync tier: the repo ships a pre-generated .hermes/skills/claude-skills/ tree, 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, run ./scripts/vibe-install.sh once locally to install into ~/.vibe/skills/. Same agentskills.io SKILL.md standard — no format conversion. Docs: .
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 — 807 CLI scripts (all stdlib-only, zero pip installs)
Reference docs — 917 templates, checklists, and domain-specific knowledge files
One repo, thirteen platforms. Works natively as Claude Code plugins, Codex agent skills, Gemini CLI skills, Hermes Agent skills, Mistral Vibe skills, and converts to more tools via scripts/convert.sh. All 807 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.
Quick Install
Windows users: clone with git clone -c core.symlinks=true (Developer Mode enabled) — otherwise the .gemini//.codex//.vibe//.hermes/ mirror trees check out as 1-line pointer text files instead of skills — and set PYTHONUTF8=1 so tools that print Unicode don't crash on legacy-codepage consoles. Details: INSTALLATION.md → Windows Notes.

Personas
Pre-configured agent identities with curated skill loadouts, workflows, and distinct communication styles. Personas go beyond "use these skills" — they define how an agent thinks, prioritizes, and communicates.
| Persona | Domain | Best For |
|---|---|---|
| Startup CTO | Engineering + Strategy | Architecture decisions, tech stack selection, team building, technical due diligence |
| Growth Marketer | Marketing + Growth | Content-led growth, launch strategy, channel optimization, bootstrapped marketing |
| Solo Founder | Cross-domain | One-person startups, side projects, MVP building, wearing all hats |
Usage:
# Claude Code
cp agents/personas/startup-cto.md ~/.claude/agents/
# Any tool
./scripts/convert.sh --tool cursor # Converts personas tooSee agents/personas/ for details. Create your own with TEMPLATE.md.
Orchestration
A lightweight protocol for coordinating personas, skills, and agents on work that crosses domain boundaries. No framework required.
Four patterns:
| Pattern | What | When |
|---|---|---|
| Solo Sprint | Switch personas across project phases | Side projects, MVPs, solo founders |
| Domain Deep-Dive | One persona + multiple stacked skills | Architecture reviews, compliance audits |
| Multi-Agent Handoff | Personas review each other's output | High-stakes decisions, launch readiness |
| Skill Chain | Sequential skills, no persona needed | Content pipelines, repeatable checklists |
Example: 6-week product launch
Week 1-2: startup-cto + aws-solution-architect + senior-frontend → Build
Week 3-4: growth-marketer + launch-strategy + copywriting + seo-audit → Prepare
Week 5-6: solo-founder + email-sequence + analytics-tracking → Ship and iterateSee orchestration/ORCHESTRATION.md for the full protocol and examples.

FAQ
How do I install Claude Code plugins? Add the marketplace with /plugin marketplace add alirezarezvani/claude-skills, then install any skill bundle with /plugin install @claude-code-skills.
Do these skills work with OpenAI Codex / Cursor / Windsurf / Aider / Mistral Vibe? Yes. Skills work natively with 13 tools: Claude Code, OpenAI Codex, Gemini CLI, OpenClaw, Hermes Agent, Mistral Vibe, Cursor, Aider, Windsurf, Kilo Code, OpenCode, Augment, and Antigravity. Hermes Agent and Mistral Vibe both use the same agentskills.io SKILL.md standard — run python scripts/sync-hermes-skills.py or ./scripts/vibe-install.sh to install. For other tools run ./scripts/convert.sh --tool all then ./scripts/install.sh --tool . See Multi-Tool Integrations for details.
Will updating break my installation? No. We follow semantic versioning and maintain backward compatibility within patch releases. Existing script arguments, plugin source paths, and SKILL.md structures are never changed in patch versions. See the CHANGELOG for details on each release.
Are the Python tools dependency-free? Yes. All 807 Python tools use the standard library only — zero pip installs required. Every skill's CLI entry point is verified to run with --help (most skills ship one script per tool; a few, like the vendored engineering/skillopt-sleep engine, ship a multi-module package behind a single python -m entry point). A few tools — engineering/book-to-skill's document extractors — can optionally use third-party parsers for higher-fidelity output, but every format falls back to a standard-library parser and nothing is installed implicitly.
How do I create my own Claude Code skill? Each skill is a folder with a SKILL.md (frontmatter + instructions), optional scripts/, references/, and assets/. See the Skills & Agents Factory for a step-by-step guide.
