anthropic-docs

Router skill for Anthropic's news + research feeds — auto-refreshed daily from anthropic.com/news and anthropic.com/research. Use when the user asks about TIME-SENSITIVE Anthropic content: model launches ("did Claude X just release?"), product announcements, partnership news, region launches, new research papers, recent policy positions, or "what's new from Anthropic?" / "what did Anthropic just announce?" / "any recent research on X?" Skip: deep technical reference (use the other 7 skills — claude-code, anthropic-api, etc.); historical news older than ~30 items (link out to anthropic.com instead); detailed paper content (the digest carries title + summary + URL — Claude WebFetches the paper for depth on demand).

Router skill for Claude Cowork — the enterprise multi-cloud surface and Office agents. Cowork covers Claude for Work deployed on third- party clouds (Amazon Bedrock, Microsoft Foundry, LLM gateways), enterprise SSO, telemetry, the M365 connector, and policy controls. Office agents covers Claude in Excel and Slack-style office integrations. Use when the user asks about: deploying Claude for Work on Bedrock or Microsoft Foundry, integrating an LLM gateway, configuring enterprise SSO, enabling telemetry / audit logs, connecting M365, applying enterprise policies, Claude in Excel, or Slack-style office agent integrations. Skip: raw API on Bedrock / Vertex (use anthropic-platform-features), user-facing connectors directory (use claude-connectors), Claude Code CLI in enterprise contexts (use claude-code).

Router skill for Claude Connectors (the user-facing MCP integration surface on claude.com), Claude Desktop extensions (MCPB packaging), MCP Apps for Claude Desktop with their visual + interaction design guidelines, the directory of pre-built integrations (GitHub, Google Workspace, Microsoft 365, Slack, …), the user-facing Agent Skills surface, and the user-facing Plugins surface. Use when the user asks about: enabling a connector in the Claude app, building a custom connector, packaging a Desktop extension (MCPB), MCP Apps visual / interaction design rules, submitting to the connectors directory, OAuth + token handling for connectors, the GitHub / Google / Microsoft / Slack connector integrations, authoring user-installable Skills, or installing plugins via the Claude app. Skip: low-level MCP protocol spec (use mcp-spec), MCP servers run by Claude Code CLI (use claude-code), MCP connector exposed by the API (use anthropic-platform-features → SKILL-agents-and-tools).

Router skill for Claude Code (the CLI tool itself). Contains intent hints and a dispatch table that maps a user's question to the surface-specific deep-reference file Claude should Read next. Use when the user asks about Claude Code internals: editing .claude/settings.json or settings.local.json, authoring or debugging hooks (PreToolUse, PostToolUse, Stop, SubagentStop, Notification, UserPromptSubmit, PreCompact, SessionStart, SessionEnd, etc.), writing slash commands or agents, configuring MCP servers in .mcp.json, building plugins or marketplaces, setting ANTHROPIC_* / CLAUDE_* env vars, troubleshooting permission modes, understanding the ~/.claude/ directory layout, or asking "what does <feature> in Claude Code do". Skip: questions about the Anthropic Messages API (use anthropic-api), the Claude Agent SDK (use claude-agent-sdk), the MCP protocol spec (use mcp-spec), or general shell / git / programming topics not specific to Claude Code internals.

Router skill for Anthropic platform-side features that sit above the raw Messages API: Agent Skills format (the spec for `.skill` packages used by platform-managed agents), MCP connectors hosted by Anthropic, tool use (computer use, code execution, bash tool, define-your-own tools), build-with-claude features (extended thinking, message batches, citations, Amazon Bedrock, Google Vertex, embeddings, fast mode, context editing), manage-claude operations (workload identity federation, billing, identity), and the Managed Agents product. Use when the user asks about: writing an Agent Skill `.skill` package, Anthropic's hosted MCP connector, MCP Tunnels (connecting private-network MCP servers without opening inbound ports), the computer-use tool, the code_execution tool, bash tool, extended thinking, message batches, prompt caching strategy at the platform level, citations, deploying via Bedrock or Vertex, embeddings models, fast-mode behavior, context editing strategies, WIF setup, billing / cost reports, identit

Router skill for the Anthropic Messages API and adjacent surfaces (admin endpoints, compliance, beta features, models catalog) hosted under platform.claude.com/docs/en/api/. Use when the user asks about: POST /v1/messages, tool_use / tool_result blocks, count_tokens, message batches, streaming responses, prompt caching, prompt cache TTL / breakpoints, system prompts, anthropic-beta headers, the admin API (organizations / workspaces / API keys / invites), compliance endpoints (data residency, audit logs, retention), beta-only features behind a beta header, or the models catalog (model IDs, deprecation dates, context window sizes). Skip: questions about Claude Code (use claude-code skill), the Claude Agent SDK (use claude-agent-sdk), platform features beyond the raw API such as Agent Skills format or tool-use guides (use anthropic-platform-features), MCP connector docs (claude-connectors), or per-language auto-generated SDK reference (use anthropic-sdk's TypeScript / Python types directly via your IDE).

Router skill for the Claude Agent SDK — Anthropic's libraries for building autonomous AI agents that wrap the Claude Code CLI runtime. Ships in TypeScript (`@anthropic-ai/claude-agent-sdk` on npm) and Python (`claude-agent-sdk` on PyPI). Covers `query()` / `ClaudeSDKClient`, hooks (PreToolUse / PostToolUse / Stop / etc.), subagents, MCP servers (stdio / HTTP / SSE / SDK in-process), permission modes, the sandbox (Docker / Kubernetes), structured outputs (JSON Schema validation), session capture / resume / fork, and session storage adapters (`SessionStore`, `InMemorySessionStore`, S3/Redis/Postgres). Use when the user asks about: importing `@anthropic-ai/claude-agent-sdk` in TypeScript or `from claude_agent_sdk import ...` in Python, writing an agent that uses `query()` or `ClaudeSDKClient`, registering hooks via the SDK (`hooks: { PreToolUse: [...] }` / `hooks={"PreToolUse": [...]}`), defining MCP servers in SDK options, configuring `permissionMode` / `permission_mode`, building subagents with `AgentDefiniti

Router skill for the Model Context Protocol (MCP) open spec, covering the protocol itself (JSON-RPC framing, capabilities, lifecycle), the client and server roles, the transport layers (stdio / streamable HTTP / SSE), and the core primitives (tools, resources, prompts, sampling, roots, completion). Use when the user asks about: writing an MCP server (in any language), writing an MCP client, the JSON-RPC protocol framing, the initialize handshake, capability negotiation, the stdio transport, the streamable HTTP transport, the SSE transport, defining a tool / resource / prompt, sampling, roots, or completion. Includes the TypeScript SDK (`@modelcontextprotocol/sdk`) and Python SDK (`mcp`). Skip: Anthropic's hosted MCP connector (use anthropic-platform-features), the user-facing Claude Connectors directory (use claude-connectors), Claude Code's `.mcp.json` config (use claude-code → SKILL-mcp).

Template starter for an Agent Skill — replace this entire description with one that names the concrete intent triggers ("Use when the user asks about X, Y, Z") and lists negative-intent Skip clauses. The platform's skill matcher reads this field — write it for matching, not for marketing. Stay under 1024 chars.

Template example showing the SKILL.md structure — replace this description with one that names YOUR skill's concrete trigger condition ("Triggers when the user asks how to X, Y, Z"). Keep it ≤200 characters for best intent-matching.
