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
# Runtime — Agent Instructions
## HTTP API Patterns
### Sending messages
The single HTTP send endpoint is `POST /v1/messages`. Key behaviors:
- **Queue if busy**: When the conversation is processing, messages are queued and processed when the current agent turn completes. No 409 rejections. Under the `interrupt-on-send` flag this is replaced by interrupt-and-replace for a user's own send: see below.
- **Fire-and-forget**: Returns `202 { accepted: true }` immediately. The client observes progress via SSE (`GET /v1/events`).
- **Hub publishing**: All agent events are published to `assistantEventHub`, making them observable via SSE.
Do NOT add new send endpoints. All message ingress should go through `POST /v1/messages` (HTTP).

How to install
mdr add vellum-ai/vellum-assistant/assistant/src/runtime/AGENTS.md@sha256:a0b66c32407d4eb6The line at the top of this page pins the label git:20261020.e743e21, 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.
