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

# Gateway — Agent Instructions

## Public API / Webhook Ingress

All inbound HTTP endpoints — APIs, webhooks, OAuth callbacks, or any route that receives requests from the internet — **MUST** be routed through the **gateway** (`gateway/`). Never add ingresses, routes, or listeners directly to the daemon runtime (`assistant/`).

Concretely:

- Define new routes in the gateway and have the gateway forward requests to the assistant over the internal HTTP transport.
- The gateway's public URL is controlled by the **public ingress URL** setting. All externally-facing URLs you generate or advertise (callback URLs, webhook registration URLs, etc.) must be derived from this setting — never hardcode a hostname or port.
- The daemon should remain unreachable from the public internet. It only receives traffic from the gateway over the internal network.

How to install

The exact contents, by fingerprint
mdr add vellum-ai/vellum-assistant/gateway/AGENTS.md@sha256:730e8a9c7c6d3715

The line at the top of this page pins the label git:20260930.08b7375, 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.
