Delegate a big or high-stakes job to a fleet of parallel subagents, orchestrated deterministically; runs unattended and reports back.
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
A workflow is a short JS/TS script you author that runs in a sandbox and fans work
out across many short-lived **leaf agents**, orchestrated deterministically. Launch
one with `run_workflow` (inline `script` OR saved `name`, exactly one). It returns a
`runId` immediately; the run is asynchronous and you are notified in this
conversation when it completes — **do NOT poll**.
Reach for one when a job is too big, too parallel, or too important for one inline
pass. That is more than batch/map-reduce over many items — it also covers exhaustively
sweeping or auditing a large surface, researching across many sources and synthesizing,
and generating several independent attempts to judge or adversarially verify before
trusting the result. For a single task or a quick lookup, do it inline.
## The script model
These are the load-bearing invariants. Get them wrong and the run misbehaves silently.
### Scripts are SYNCHRONOUS — never `await`
Host functions block and return their result directly. Write straight-line code.
```js
const r = agent("Summarize this thread."); // r is the result, right here
```
Do **not** write `await agent(...)`, and do **not** make the script `async`. An

How to install
mdr add vellum-ai/vellum-assistant/workflows@sha256:5570cd8aee85b5fbThe line at the top of this page pins the label git:20260622.69c562a, 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.
