example-skills — Agent Skill Profile

What it actually does

One plugin bundling twelve Anthropic reference skills at once, including `skill-creator`, `mcp-builder`, `webapp-testing`, `frontend-design`, `canvas-design`, `theme-factory`, and `brand-guidelines`.
`skill-creator` specifically runs Anthropic's eval workflow — a with-skill-vs-without-skill benchmark across isolated subagent runs, plus a blind A/B between two versions of a skill.

When to use it — and when not to

Use it when

You want Anthropic's own reference implementations for building, testing, or evaluating skills, or for frontend/design/MCP work.
You specifically want `skill-creator`'s eval workflow to check whether a skill you wrote actually helps.

Not for

You only want one of the twelve — the plugin route installs all twelve together (though nothing stops copying a single skill's folder into `~/.claude/skills/` by hand).

The caveat that matters

It's a twelve-skill grab-bag, not twelve independent listings — evaluate it as one bundle, not by any single sub-skill's name.

Agent compatibility

Claude Code

Confirmed means the skill’s own source or vendor states it works with that agent. Portable means it only reaches that agent through the shared SKILL.md format and a directory convention — real, but a weaker claim. An agent with no entry here isn’t known to be unsupported; it simply isn’t documented either way, so nothing is claimed. Full model on Agent Skills Compatibility.

Evidence and provenance

Maintained by Anthropic (official). Primary source: anthropics/skills, last checked against this page’s claims on August 16, 2026. This page summarizes and analyzes that source — it isn’t a copy of its SKILL.md or README, and installation happens at the source, not here.
