Plugin Authoring
Skill Verified ActiveUse when creating, modifying, or debugging Claude Code plugins. Triggers on .claude-plugin/, plugin.json, marketplace.json, commands/, agents/, skills/, hooks/ directories. Provides schemas, templates, validation workflows, and troubleshooting.
To serve as the definitive guide for developers creating and maintaining Claude Code plugins, ensuring adherence to best practices and facilitating efficient development.
Features
- Provides schemas, templates, and validation workflows for plugin development.
- Offers troubleshooting guidance for common plugin issues.
- Triggers on relevant plugin development directories and files.
- Includes comprehensive checklists and red flags for developers.
Use Cases
- Creating a new Claude Code plugin from scratch.
- Modifying an existing plugin's commands, skills, or hooks.
- Debugging why a plugin is not loading or its components are not recognized.
- Ensuring a plugin adheres to best practices before release.
Non-Goals
- Developing the plugins themselves (the skill guides the developer).
- Directly managing the Claude Code environment outside of plugin installation.
- Writing plugin code directly (the skill guides the process, users implement).

Validate Plugin
100Validate a Claude Code plugin structure, frontmatter, and MCP tool references
Product Self Knowledge
100Stop and consult this skill whenever your response would include specific facts about Anthropic's products. Covers: Claude Code (how to install, Node.js requirements, platform/OS support, MCP server integration, configuration), Claude API (function calling/tool use, batch processing, SDK usage, rate limits, pricing, models, streaming), and Claude.ai (Pro vs Team vs Enterprise plans, feature limits). Trigger this even for coding tasks that use the Anthropic SDK, content creation mentioning Claude capabilities or pricing, or LLM provider comparisons. Any time you would otherwise rely on memory for Anthropic product details, verify here instead — your training data may be outdated or wrong.
Running Claude Code Via Litellm Copilot
100Use when routing Claude Code through a local LiteLLM proxy to GitHub Copilot, reducing direct Anthropic spend, configuring ANTHROPIC_BASE_URL or ANTHROPIC_MODEL overrides, or troubleshooting Copilot proxy setup failures such as model-not-found, no localhost traffic, or GitHub 401/403 auth errors.
Guard
100Protect Claude Code sessions from context overflow by running a background daemon that monitors session size and auto-prunes before compaction hits. Use when the user says "guard", "protect session", "context getting long", "prevent compaction", "session management", or is running agent teams that need continuous context protection.
Create Command
100Interactive assistant for creating new Claude commands with proper structure, patterns, and MCP tool integration
Rule Effectiveness Analysis
100Analyze which rules are actively used vs inert. Detect coverage gaps. Recommend pruning to reduce token consumption.
