Agent Skills: copilot-cli-agent-customization
**WORKFLOW SKILL** — Create, update, review, fix, or debug Copilot CLI customization files (`copilot-instructions.md`, `AGENTS.md`, `*.instructions.md`, `*.agent.md`, `SKILL.md`, hook JSON, `plugin.json`, and plugin command files). USE FOR: authoring terminal-first customization workflows; troubleshooting why CLI instructions, skills, agents, hooks, or plugins are ignored; configuring `applyTo` and `excludeAgent`; defining CLI tool restrictions; creating custom agents or command packs; packaging reusable CLI customizations. DO NOT USE FOR: general coding questions; non-customization runtime debugging; Copilot in VS Code customization (use `copilot-vscode-agent-customization` instead); MCP server configuration; VS Code prompt files or extension development. INVOKES: file system tools, ask-questions tool, subagents for codebase exploration. FOR SINGLE OPERATIONS: For quick YAML or JSON fixes, or for creating one known file from a clear pattern, edit directly instead of loading the full skill.

- diataxisCreate and evaluate documentation using the Diátaxis framework. Use when writing, organizing, or auditing documentation to ensure it serves distinct user needs through four systematic categories (Tutorials, How-to Guides, Reference, Explanation). Ideal for diagnosing documentation problems, separating mixed content, and ensuring each piece serves a single, clear purpose.
- hook-developmentThis skill should be used when the user asks to "create a hook", "add a PreToolUse/PostToolUse/Stop hook", "validate tool use", "implement prompt-based hooks", "use ${CLAUDE_PLUGIN_ROOT}", "set up event-driven automation", "block dangerous commands", or mentions hook events (PreToolUse, PostToolUse, Stop, SubagentStop, SessionStart, SessionEnd, UserPromptSubmit, PreCompact, Notification). Provides comprehensive guidance for creating and implementing Claude Code plugin hooks with focus on advanced prompt-based hooks API.
- sf-apex>
- filesystem-contextThis skill should be used when agent work needs file-backed context: durable scratchpads, tool-output offloading, just-in-time discovery, cross-agent handoff files, filesystem memory, or cleanup policies for context stored outside the prompt.
- pinme-authUse when a PinMe project (Worker TypeScript) needs to integrate user authentication — creating email/password users, verifying id_tokens, querying user info, or listing users via Identity Platform auth proxy APIs.
- onchainkitBuild onchain applications with React components and TypeScript utilities from Coinbase's OnchainKit. Use when users want to create crypto wallets, swap tokens, mint NFTs, build payments, display blockchain identities, or develop any onchain app functionality. Supports wallet connection, transaction building, token operations, identity management, and complete onchain app development workflows.
