Implement production applications with Anthropic Claude models -- Messages API, tool use, prompt caching, adaptive thinking, vision, computer use, and the Claude Agent SDK. Use when coding directly against Anthropic APIs, Claude via AWS Bedrock, or Claude via GCP Vertex AI rather than a higher-level framework.
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
# Anthropic Claude > WHEN: Writing implementation code against Anthropic Claude models directly via the Messages API, or via Amazon Bedrock / GCP Vertex AI, or via the Claude Agent SDK. ## When to Use - Calling Claude models directly with the Anthropic Messages API - Deploying Claude on AWS Bedrock or GCP Vertex AI - Building tool-using Claude agents with the Claude Agent SDK - Adding prompt caching, adaptive thinking, or vision to a Claude app - Migrating from another LLM provider to Claude and preserving behavior ## Decision Tree ``` Need Claude in production? +- Direct Anthropic API? | - Use anthropic SDK (python or typescript) +- AWS-hosted workload? | - Use Claude on Amazon Bedrock via boto3 / AWS SDK +- GCP-hosted workload? | - Use Claude on Vertex AI via google-cloud-aiplatform +- Agentic loop with tools, files, shell? | - Use Claude Agent SDK +- Framework already chosen (LangChain, MAF, LangGraph)? - Use the provider adapter rather than raw SDK ``` ## Core Rules 1. Always send a `system` prompt separately from the `messages` array -- Claude separates system instruction from the turn history. …

How to install
mdr add jnpiyush/agentx/anthropic-claude@sha256:155c4d27de4408f4The 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.
