# Anthropic Skills
Two skills from [anthropics/skills](https://github.com/anthropics/skills). Read the one the task needs and follow it.
| Skill | Use when | Read |
| --- | --- | --- |
| `skill-creator` | Creating or improving a skill, running evals and benchmarks for it, or optimizing its description. | [skill-creator/SKILL.md](skill-creator/SKILL.md) |
| `mcp-builder` | Building or reviewing an MCP server and its tools. | [mcp-builder/SKILL.md](mcp-builder/SKILL.md) |
Both skills end with an "In Space" section. Repository and operator instructions (`AGENTS.md`) take precedence. Superpowers' `writing-skills` covers writing a skill test-first; `skill-creator` adds the evaluation, benchmark and description-tuning loop.
Source and licenses: [UPSTREAM.md](UPSTREAM.md).
