AnthropicSkillanthropics/claude-plugins-official/plugins/math-olympiad/skills/math-olympiad/SKILL.md
1. Strip thinking before verifying — a verifier that sees the reasoning is biased toward agreement. Fresh context, cleaned proof only. 2. "Does this prove RH?" — if your theorem's specialization to ζ is a famous open problem, you have a gap. Most reliable red flag. 3. Short proof → extract the general lemma — try 2×2 counterexamples. If general form is false, find what's special about THIS instance. 4. Same gap twice → step back — the case split…
AnthropicSkillanthropics/claude-plugins-official/plugins/mcp-server-dev/skills/build-mcp-app/SKILL.md
This skill should be used when the user wants to build an "MCP app", add "interactive UI" or "widgets" to an MCP server, "render components in chat", build "MCP UI resources", make a tool that shows a "form", "picker", "dashboard" or "confirmation dialog" inline in the conversation, or mentions "apps SDK" in the context of MCP. Use AFTER the build-mcp-server skill has settled the deployment model, or when the user already knows they want UI widgets.
AnthropicSkillanthropics/claude-plugins-official/plugins/mcp-server-dev/skills/build-mcpb/SKILL.md
This skill should be used when the user wants to "package an MCP server", "bundle an MCP", "make an MCPB", "ship a local MCP server", "distribute a local MCP", discusses ".mcpb files", mentions bundling a Node or Python runtime with their MCP server, or needs an MCP server that interacts with the local filesystem, desktop apps, or OS and must be installable without the user having Node/Python set up.

It is the entry point for MCP server development — it interrogates the user about their use case, determines the right deployment model (remote HTTP, MCPB, local stdio), picks a tool-design pattern, and hands off to specialized skills.
AnthropicSkillanthropics/claude-plugins-official/plugins/playground/skills/playground/SKILL.md

Provides comprehensive guidance for integrating Model Context Protocol servers into Claude Code plugins for external tool and service integration.
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.
