What are Agent Skills? Agent Skills are a lightweight, open format (agentskills.io) for giving AI agents specialized capabilities. Each skill is a folder with a SKILL.md file containing instructions, plus optional scripts, references, and test suites.
Which platforms support Agent Skills? Claude Code, Claude CLI, Claude Projects, Claude API, OpenAI Codex, Gemini CLI, Cursor, OpenClaw, GitHub Copilot, Hermes Agent, OpenCode, Amp, Junie, and any SKILL.md-compatible agent.
Why are skills nested under categories?
gh skill and the agentskills.io specification discover skills at skills/*/SKILL.md and skills/{scope}/*/SKILL.md — category folders map to the {scope} position, so gh skill install, gh skill publish, and the agentskills.io CLI all resolve nested skills natively. Categories keep a 40-skill library browsable.
How do I install a skill?
Via GitHub CLI: gh skill install JPeetz/agent-skills [skill-name]. Or manually: copy the skill directory to your agent's skills folder. Common paths: ~/.agents/skills/ (cross-client), ~/.claude/skills/ (Claude Code), .codex/skills/ (Codex), .cursor/skills/ (Cursor), ~/.openclaw/workspace/skills/ (OpenClaw).
How often are new skills added? New skills ship every Tuesday and Thursday. Each skill is researched, scored, improved, and validated before publication.
What domains do these skills cover? Business strategy (app discovery, market analysis), development (app scaffolding, API design-first, GraphQL API development), Frontend/Design (design-to-code, accessibility compliance), DevOps/SRE (CI/CD pipeline generation, infrastructure-as-code guardian, production engineering workflows, SRE runbooks, Kubernetes operations, observability engineering), Git workflow automation (commits, PRs, changelogs, releases), code quality (AI-powered code review covering security, architecture, performance), data (data analysis and visualization, dbt analytics engineering, database schema design), compliance and privacy (GDPR, CCPA, HIPAA, EU AI Act, cross-border transfers), QA and testing (Playwright E2E testing, browser automation), security (supply chain scanner, agentic security scanner, SBOM, dependency scanning, provenance verification), content and documents (PDF/DOCX/XLSX/PPTX processing, technical documentation), marketing (ad campaign generation).
How can I submit a skill? Open an issue or PR. See CONTRIBUTING.md. Skills are reviewed against our quality framework before merging.
Are skills tested? Every skill includes an eval suite (evals/evals.json) with test cases, should-trigger/not-trigger scenarios, and verifiable assertions. Skills are validated against the agentskills.io specification.
- SKILL.md validation (frontmatter, body limits, description quality)
- Eval suite (min 5 test cases per skill)
- Corrections log (real failures documented)
- Self-contained scripts (PEP 723 inline dependencies)
- Platform notes when behavior differs across agents
- Changelog per skill
- MIT license
This repository is maintained autonomously by Skill Foundry — an AI department of AgentForge. Skills are discovered, evaluated, improved, and published on a twice-weekly cadence. Quality beats volume. Every run leaves the repo better than before.
