Skills Collection

Agent skills are the open standard for packaging specialized knowledge into portable folders. A skill is just a SKILL.md plus optional scripts, references, and assets — installable in Claude Code, OpenCode, Gemini CLI, Codex, Cursor, and 40+ other agents. One skill, every tool.

This collection is a curated catalog, not a registry. The skills.sh marketplace has thousands of unaudited skills; ~26% of them carry security issues ranging from prompt injection to credential exfiltration. Discovery is no longer the bottleneck — judgment is. Every skill here has been reviewed against the open standard and tagged with what we checked, which models reviewed it, and when. That review is transparency, not a trust seal: repos change silently, so we ship instructions on every page for you to verify the skill with your own models before installing.

What's in the collection

The open standard

Skills conform to agentskills.io, the open format originally developed by Anthropic and now adopted by ~40 products. Every skill is a folder with a SKILL.md:

my-skill/
├── SKILL.md          # Required: frontmatter + instructions
├── scripts/          # Optional: executable code
├── references/       # Optional: documentation
└── assets/           # Optional: templates, resources

SKILL.md frontmatter has six fields (name, description, license, compatibility, metadata, allowed-tools) and the body is loaded only on skill activation — agents use progressive disclosure so installing 20 skills doesn't cost 20 instruction sets upfront. The same skill file runs unmodified in Claude Code, OpenCode, Codex, and Gemini CLI.

Install it once, run it anywhere

npx skills add <github-org>/<repo>

How to read a skill page

Every skill page follows the same template so you can compare them at a glance:

1. Overview — what it does, who maintains it, adoption signal
2. When to use / when not — the realistic job
3. How it works — the SKILL.md anatomy, scripts, progressive disclosure
4. Install tabs — npx skills add, Claude Code, OpenCode, Codex
5. Full SKILL.md — copyable source after the vetting gate passes
6. "Verify it yourself" — the condensed red-flag checklist + a copyable review prompt you can paste into your own model
7. Review transparency — what we checked, which models, when
8. Source + credits + license — where it came from, what you can do with it
