First Added:May 6, 2026 Updated: May 17, 2026

A living research document tracking good sources of agent skills to draw from. Covers Claude Code, Gemini CLI, and cross-ecosystem skill/prompt repositories.

Maintenance: Review quarterly. Update “last checked” dates when vetting a source. Remove dead or low-quality links.

Blurb

The SKILL.md format is an open standard for teaching thinking AI models specific, repeatable skills. A growing ecosystem of community repositories, marketplaces, and cross-agent collections makes skills portable across Claude Code, Gemini CLI, Cursor, Codex, and others.

Cross-Ecosystem Inspiration

Not SKILL.md format, but good sources for ideas — patterns that adapt directly.

Evaluation Criteria

When vetting a new source:

  1. Format compliance — Is it SKILL.md format, or requires adaptation?
  2. Cross-agent portability — Works only in Claude Code, or also Gemini CLI / Cursor / Hermes?
  3. Maintenance signal — Last commit date, open issues, star trajectory.
  4. Domain fit — DevSecOps, PKM, automation — relevant to Kamenik Solutions or personal use?
  5. Quality bar — Are skills self-contained with a clear trigger description in frontmatter?
