name	anthropic-api
description	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).

Anthropic API Reference — Router

This skill is auto-updated daily. A pipeline reads the upstream docs and rewrites the per-surface files below. Section structure is stable; content drifts to track upstream.

Dispatch table

Surface file	Read when the user asks about…
SKILL-messages.md	POST /v1/messages, request/response shape, tool_use / tool_result content blocks, streaming (stream: true), system prompts, count_tokens, message batches; also legacy /v1/complete (text completions)
SKILL-admin.md	admin API — organizations, workspaces, API keys, invites, usage reports, cost reports
SKILL-compliance.md	data residency, audit logs, retention policies, compliance API endpoints
SKILL-beta.md	features gated behind anthropic-beta header, beta endpoints, opt-in feature flags
SKILL-models.md	model IDs (claude-opus-4-7, claude-sonnet-4-6, claude-haiku-4-5-20251001, …), context window sizes, deprecation dates, model card / capabilities

Out of scope for this skill (intentionally excluded by docsPathFilter): the auto-generated per-language SDK reference under platform.claude.com/docs/en/api/{cli,csharp,go,java,php,python,ruby,terraform,typescript}/ (~1100 pages). Use your IDE's type-defs from @anthropic-ai/sdk (npm) or anthropic (PyPI) for those — they ship the authoritative signatures and stay in sync with the SDK release you're using.

Auto-correction rules

Rule file	Triggers on edits to
rules/messages-api.md	code calling client.messages.create, POST /v1/messages, or constructing tool_use / tool_result content blocks
