What Is an Agent Skill?

An agent skill is a portable package of expertise your AI assistant can load on demand. Instead of re-explaining your standards in every prompt, a skill gives the agent a structured workflow it follows the same way every time — whether that's reviewing a pull request, designing a pricing model, or preparing an ISO 27001 audit.

Every skill in this library follows the same simple anatomy:

skill-name/
├── SKILL.md          # The playbook — workflows, rules, decision frameworks
├── scripts/          # Python CLI tools (stdlib-only, no pip installs)
├── references/       # Curated domain knowledge the agent can consult
└── assets/           # Ready-to-use templates for your team

No API keys, no external services, no dependencies between skills. Copy a folder — or install a plugin — and it works.

  • Install Add the marketplace to Claude Code, or run one sync script for Codex, Gemini CLI, Cursor, and 9 more tools.
  • Invoke Call a slash command like /cs:deal-review, or just mention the skill in a prompt — the agent loads the playbook.
  • Ship The agent works through the skill's checklists and tools, producing consistent, reviewable output every time.

Why Teams Use This Library

  • Zero dependencies

    Every Python tool uses the standard library only. No pip installs, no API keys, no configuration. Works anywhere Python runs.

  • Security first

    A built-in security auditor scans any skill for malicious code, data exfiltration, and prompt injection before you install it.

  • One-command install

    A plugin marketplace for Claude Code, sync scripts for Codex, Gemini, Hermes, and Vibe, and a converter for seven more tools.

  • Self-contained

    Each skill is independent — no cross-dependencies, no conflicts. Install one or all; they work in isolation.

  • Multi-platform

    Native support for 13 AI coding tools. Write once, convert to any tool's format automatically.

  • Production-grade

    Structured workflows with validation checkpoints — not generic advice. Each skill covers an end-to-end process with named deliverables.
