What are Skills?

Skills are markdown files that give AI agents specialized knowledge and workflows for specific tasks. When you add these to your project, your agent can recognize when you're working on a task and apply the right frameworks and best practices.

🚀 Active Skills

• GitHub OS: Set up GitHub as your project's Operating System - execution layer integrated with docs as knowledge layer, optimized for LLM workflows.
• Playwright Extension Testing: Gold-standard E2E for MV3/WXT extensions.
• Peer LLMs: Inter-LLM collaboration workflows — enables delegation, review, and execution across LLM providers.
  • Codex CLI: Delegates coding tasks to Codex CLI for batch refactoring, code generation, multi-file changes.
  • OpenCode CLI: Delegates coding tasks to OpenCode CLI with streaming JSON output and session reuse.
  • Plan Review: Reviews technical plans via a coding agent with iterative refinement.
  • Plan Execute: Executes finalized plans by delegating to a coding agent with Claude/codex orchestrator.
• Lesson Decision Records: Systematic recording of AI mistakes and learnings using ADR-inspired format.
• Context Hub Get API Docs: Fetch current API documentation for third-party libraries and SDKs via chub CLI.

Installation

Option 1: CLI Install (Recommended)

Use npx skills to install skills directly:

# Install all skills
npx skills add ZenStudioLab/skills

# Install specific skills
npx skills add ZenStudioLab/skills --skill lesson-decision-records
npx skills add ZenStudioLab/skills --skill get-api-docs

# List available skills
npx skills add ZenStudioLab/skills --list

This automatically installs to your .agents/skills/ directory.

Option 2: Clone and Copy

Clone the entire repo and copy the skills folder:

git clone https://github.com/ZenStudioLab/skills.git
cp -r skills/skills/* .agents/skills/

Option 3: Git Submodule

Add as a submodule for easy updates:

git submodule add https://github.com/ZenStudioLab/skills.git .agents/zenstudiolab-skills

Then reference skills from .agents/zenstudiolab-skills/skills/.

🛠️ Usage

Integrated via skills.sh.

Once installed, just ask your agent to help with tasks:

"Set up GitHub OS for this repository" → Uses GitHub OS skill

"Help me set up Playwright E2E testing for my MV3 extension" → Uses Playwright Extension Testing skill

"Delegate this refactoring to Codex CLI" → Uses Peer LLMs skill (Codex integration)

"/plan-review ./plans/my-feature.md" → Uses Peer LLMs skill (plan-review, defaults to codex)

"/plan-execute ./plans/my-feature.md" → Uses Peer LLMs skill (plan-execute, defaults to codex)

"/plan-review opencode ./plans/my-feature.md" → Uses Peer LLMs skill (plan-review, overrides to opencode)

"/plan-execute opencode ./plans/my-feature.md" → Uses Peer LLMs skill (plan-execute, overrides to opencode)

"Create a Lesson Decision Record for a recent bug" → Uses Lesson Decision Records skill

"Get the latest OpenAI API documentation" → Uses Context Hub Get API Docs skill
