Multi-agent coordination patterns for delegating work between specialized agents, managing agent roles, and orchestrating workflows across multiple AI agents.
This skill should be used when the user asks to "find past conversations", "recall what was done", "search history", "look up previous work", "how did we handle X", "what was that implementation", "find similar code", "search session", "analyze conversation history", "recover file", "restore previous version", or mentions terms like "earlier", "before", "previously", "last time", "history", "past work".
Build and maintain effective CLAUDE.md files that improve Claude Code efficiency. Use when creating a new CLAUDE.md file, auditing/improving an existing one, setting up progressive disclosure with agent documentation, or optimizing context window usage for Claude Code projects.
Expert guide for claude-agent-sdk development questions - tools, subagents, permissions, hooks, sessions, MCP integration, and best practices.
Implement real-time data streaming with Server-Sent Events (SSE), WebSockets, and ReadableStream APIs. Master backpressure handling, reconnection strategies, and LLM streaming for 2025+ real-time applications.
This skill should be used when the user asks about "deploying", "production", "Agent Engine", "Vertex AI", "Cloud Run", "GKE", "Kubernetes", "hosting", "scaling", "guardrails", "safety", "content filtering", "input validation", "output validation", "authentication", "OAuth", "API keys", "credentials", "security plugins", "testing agents", "evaluation", "evals", "benchmarks", "tracing", "Cloud Trace", "logging", "observability", "AgentOps", "LangSmith", "user simulation", or needs guidance on deploying ADK agents to production environments, implementing safety measures, access control, secure authentication, testing, debugging, monitoring, or evaluating ADK agent quality.
Create and manage Claude Code skills following Anthropic best practices. Use when creating new skills, modifying skill-rules.json, understanding trigger patterns, working with hooks, debugging skill activation, or implementing progressive disclosure. Covers skill structure, YAML frontmatter, trigger types (keywords, intent patterns, file paths, content patterns), enforcement levels (block, suggest, warn), hook mechanisms (UserPromptSubmit, PreToolUse), session tracking, and the 500-line rule.
Centralized AI-readable documentation repository with 245+ frameworks and tools. Use to find documentation, add new sources, or update existing docs. Located at ~/github/llm-code-docs.
Upgrades external Claude Skills to factory spec - analyzes existing skill folders and generates missing files, restructures docs, validates compliance
Guide for creating Claude Code slash commands. Use when the user wants to create a new slash command, update an existing slash command, or asks about slash command syntax, frontmatter options, or best practices.
Automates updating googleai_dart when Google AI OpenAPI spec changes. Fetches latest spec, compares against current, generates changelogs and prioritized implementation plans. Use for: (1) Checking for API updates, (2) Generating implementation plans for spec changes, (3) Creating new models/endpoints from spec, (4) Syncing local spec with upstream. Triggers: "update api", "sync openapi", "new endpoints", "api changes", "check for updates", "update spec", "api version", "fetch spec", "compare spec", "what changed in the api", "implementation plan".
Activates when user needs help with performance optimization, profiling, or improving code efficiency. Triggers on "optimize performance", "make this faster", "reduce memory", "profile this", "performance issues", "slow code", "improve speed", or efficiency-related questions.
Prompt engineering guidance for Claude (Anthropic) model. Use when crafting prompts for Claude to leverage XML-style tags, long-context capabilities, extended thinking, and strong instruction following.
Guide for creating effective skills. This skill should be used when users want to create a new skill (or update an existing skill) that extends Claude's capabilities with specialized knowledge, workflows, or tool integrations.
Unified virtual filesystem framework for LLM agents. Provides access to files, memory, RAG, plugins, and snapshots through a single interface. Use this skill when the user requests file operations, memory storage, semantic search, plugin execution, or state management tasks.
Multi-agent orchestration system using Claude Code's native background agents (2.0.64+) for true parallel collaboration. Enables shared context, sync barriers between phases, and coordinator oversight. Use for complex tasks benefiting from parallel execution (epics, large refactors, multi-phase features). Do NOT use for simple tasks or sequential workflows - the coordination overhead isn't justified.
Create effective Claude Code sub-agents for project-level workflows. Use PROACTIVELY when creating new sub-agents, improving existing agents, understanding YAML frontmatter structure (name, description, tools, model, color), designing agent activation strategies with CLAUDE.md integration, writing effective descriptions with PROACTIVELY/MUST BE USED/<example> patterns, or troubleshooting agent activation issues (~25% activation rate problem).
Generate project-level AGENTS.md guides that capture conventions, workflows, and required follow-up tasks. Use when a repository needs clear agent onboarding covering structure, tooling, testing, task flow, README expectations, and conventional commit summaries.
