Use this agent when the user asks to "create an agent", "generate an agent", "build a new agent", "make me an agent that...", or describes agent functionality they need. Trigger when user wants to create autonomous agents for plugins. <example> Context: User wants to create a code review agent user: "Create an agent that reviews code for quality issues" assistant: "I'll use the agent-creator agent to generate the agent configuration." <commentary> User requesting new agent creation, trigger agent-creator to generate it. </commentary> </example> <example> Context: User describes needed functionality user: "I need an agent that generates unit tests for my code" assistant: "I'll use the agent-creator agent to create a test generation agent." <commentary> User describes agent need, trigger agent-creator to build it. </commentary> </example> <example> Context: User wants to add agent to plugin user: "Add an agent to my plugin that validates configurations" assistant: "I'll use the agent-creator agent to generate a configuration validator agent." <commentary> Plugin development with agent addition, trigger agent-creator. </commentary> </example>

Use this agent when the user asks to "validate my plugin", "check plugin structure", "verify plugin is correct", "validate plugin.json", "check plugin files", or mentions plugin validation. Also trigger proactively after user creates or modifies plugin components. <example> Context: User finished creating a new plugin user: "I've created my first plugin with commands and hooks" assistant: "Great! Let me validate the plugin structure." <commentary> Plugin created, proactively validate to catch issues early. </commentary> assistant: "I'll use the plugin-validator agent to check the plugin." </example> <example> Context: User explicitly requests validation user: "Validate my plugin before I publish it" assistant: "I'll use the plugin-validator agent to perform comprehensive validation." <commentary> Explicit validation request triggers the agent. </commentary> </example> <example> Context: User modified plugin.json user: "I've updated the plugin manifest" assistant: "Let me validate the changes." <commentary> Manifest modified, validate to ensure correctness. </commentary> assistant: "I'll use the plugin-validator agent to check the manifest." </example>

Use this agent when the user has created or modified a skill and needs quality review, asks to "review my skill", "check skill quality", "audit skill compliance", or wants to ensure skill follows official Anthropic specifications and best practices. Trigger proactively after skill creation or before commits/PRs. <example> Context: User just created a new skill user: "I've created a PDF processing skill" assistant: "I'll use the skill-reviewer agent to audit the skill for compliance and effectiveness." <commentary> Skill created, proactively trigger skill-reviewer to ensure it follows official requirements. </commentary> </example> <example> Context: User requests skill review before commit user: "Before I commit this skill, can you make sure it follows all the requirements?" assistant: "I'll audit the skill to ensure it meets official requirements and best practices." <commentary> Pre-commit validation request triggers comprehensive audit. </commentary> </example> <example> Context: User suspects skill has triggering issues user: "This skill doesn't seem to be triggering correctly. Can you check if there are any issues?" assistant: "I'll perform a comprehensive audit to identify any compliance or effectiveness issues." <commentary> Agent helps diagnose skill problems through systematic review. </commentary> </example>

This skill should be used when the user asks to "create an agent", "add an agent", "write a subagent", "agent frontmatter", "when to use description", "agent examples", "agent tools", "agent colors", "autonomous agent", or needs guidance on agent structure, system prompts, triggering conditions, or agent development best practices for Claude Code plugins.

This skill should be used when the user asks to "create a slash command", "add a command", "write a custom command", "define command arguments", "use command frontmatter", "organize commands", "create command with file references", "interactive command", "use AskUserQuestion in command", or needs guidance on slash command structure, YAML frontmatter fields, dynamic arguments, bash execution in commands, user interaction patterns, or command development best practices for Claude Code.

This 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.

This skill should be used when the user asks to "add MCP server", "integrate MCP", "configure MCP in plugin", "use .mcp.json", "set up Model Context Protocol", "connect external service", mentions "${CLAUDE_PLUGIN_ROOT} with MCP", or discusses MCP server types (SSE, stdio, HTTP, WebSocket). Provides comprehensive guidance for integrating Model Context Protocol servers into Claude Code plugins for external tool and service integration.

This skill should be used when the user asks about "plugin settings", "store plugin configuration", "user-configurable plugin", ".local.md files", "plugin state files", "read YAML frontmatter", "per-project plugin settings", or wants to make plugin behavior configurable. Documents the .claude/plugin-name.local.md pattern for storing plugin-specific configuration with YAML frontmatter and markdown content.

This skill should be used when the user asks to "create a plugin", "scaffold a plugin", "understand plugin structure", "organize plugin components", "set up plugin.json", "use ${CLAUDE_PLUGIN_ROOT}", "add commands/agents/skills/hooks", "configure auto-discovery", or needs guidance on plugin directory layout, manifest configuration, component organization, file naming conventions, or Claude Code plugin architecture best practices.

This skill should be used when the user wants to "create a skill", "add a skill to plugin", "write a new skill", "improve skill description", "organize skill content", or needs guidance on skill structure, progressive disclosure, or skill development best practices for Claude Code plugins.
