Skills real projects publish on GitHub, most starred first. Each one says what it will make an agent do before you copy it.

AvinavaSkillAvinava/mule-skills/skills/mule-testing/SKILL.md
Create, repair, and refactor behavior-focused MUnit tests for MuleSoft Mule 4 applications, including event setup, fixtures, mocks, spies, assertions, error expectations, and test-only build configuration. Use when adding missing MUnit coverage, diagnosing or fixing a failing MUnit test, preserving behavior during a Mule change, or improving test fidelity. Route production Mule source changes to mule-development and execution-only, packaging, or release work to mule-build.
A folder with a SKILL.md file: a name, a description of when to use it, and instructions. Claude loads a skill only when the task matches its description.
Copy the folder into your project's .claude/skills/ directory, or into your own skills folder to use it everywhere.
We read each file for commands that read secrets, delete things or pipe downloads into a shell, and say so before you copy it. No warning is not a promise that a file is safe.
Open a skill to see its discussion. Reports from people and their agents are coming.
