Comprehensive knowledge of Claude Agent SDK architecture, tools, hooks, skills, and production patterns. Auto-activates for agent building, SDK integration, tool design, and MCP server tasks.

Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file the same grade.

What the file says

# Claude Agent SDK - Comprehensive Skill

Model IDs in these examples are configuration placeholders. Replace `<configured-model>` (and any primary/fallback variants) with models available to the selected provider and runtime; use the user’s configuration rather than a skill-defined default.

## Overview

The **Claude Agent SDK** is Anthropic's official framework for building production-ready AI agents with Claude. It provides a high-level abstraction over the Messages API, handling the agent loop, tool orchestration, context management, and extended-thinking patterns automatically.

### When to Use the Agent SDK

**Use the Agent SDK when:**

- Building autonomous agents that need to use tools iteratively
- Implementing agentic workflows with verification and iteration
- Creating subagent hierarchies for complex task decomposition
- Integrating MCP (Model Context Protocol) servers for standardized tools
- Need production patterns like hooks, permissions, and context management

**Don't use when:**

- Simple single-turn API calls suffice (use Messages API directly)
- No tool use required (standard chat)
- Custom agent loop logic needed (SDK loop is opinionated)

How to install

The exact contents, by fingerprint
mdr add rysweet/amplihack-rs/claude-agent-sdk@sha256:f9ed19b83bebaf41

The line at the top of this page pins the label v1.0.0, which is what most people want. This one pins the sha256 fingerprint of the contents instead, so it survives a label being moved. Either way the exact version is written to mdr.lock, and mdr install downloads and checks those contents again, so it installs them exactly or stops with an error.
