Skill Base

Open-source skills for AI agents.

skill-base is a reusable library of structured skills that work across Codex, Claude, and other agent runtimes. Skills are grouped by domain, written in a consistent format, and designed so teams can copy them directly into their own projects.

Why This Repository

  • Build reliable agent workflows with reusable, reviewable skill files.
  • Keep skill outputs predictable with a shared contract.
  • Help teams quickly skim, copy, and compose domain-specific skills.

Quick Start

Option 1: Copy one skill

cp skills/engineering/code-review-checklist.md /path/to/your-project/skills/

Option 2: Copy a full domain

cp -R skills/security /path/to/your-project/skills/

Option 3: Clone and curate

git clone https://github.com/danhdox/skill-base.git

Use With Any Agent

You can invoke these skills with:

  • Codex-style workflows
  • Claude-style workflows
  • Internal agent frameworks and prompt runners
  • Manual human-in-the-loop review flows
