Build or debug stateful applications that specifically use Cloudflare's `agents` package, including Agent classes, routing, callable methods, synchronized state, scheduling, AIChatAgent, durable execution, or Agents SDK client hooks. Do not trigger for generic AI-agent design, the OpenAI Agents SDK, or ordinary Durable Object work that does not use the Cloudflare Agents SDK.
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
# Cloudflare Agents SDK Use current Cloudflare documentation and the installed `agents` package as the contract. APIs in this SDK evolve quickly; do not trust remembered signatures or examples without checking the relevant version. ## Inspect first 1. Read the project's package version, Wrangler configuration, Agent exports, routing entrypoint, and generated binding types. 2. Retrieve the current docs for the feature being changed. 3. Inspect installed exports and `.d.ts` files before adding casts or adapters. 4. Identify the Agent instance name and who is authorized to select it. Instance naming is a state-partition and access-control decision, not just a URL detail. Agents require Durable Objects. Verify the exact class export, binding, and lifecycle declaration used by the target environment. Do not copy a migration or configuration example without checking the current lifecycle model. ## Preserve the runtime contract - Treat persisted Agent state, connection state, scheduled work, and client UI state as separate surfaces. - Validate client-originated state and callable methods at the server boundary; a callable method is not authorization by itself. …

How to install
mdr add swyxio/skills/agents-sdk@sha256:839e8d950f0c6e0aThe line at the top of this page pins the label git:20260820.cd23820, 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.
