Create, review, and run typed TypeScript agents and workflows with Rig. Use when writing Rig programs, generating runnable rig markdown fences, defining agent schemas and prompt intents, or configuring Rig engines and addons.
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
# rig
Minimal TypeScript harness for typed agents in sandboxed workflows and runnable `rig` markdown fences.
Use this file for construction defaults. Load only the focused reference named by the task; do not read every reference preemptively.
## Canonical program
```ts
import { agent, p, s } from "rig";
// Agent role: review the current diff and return prioritized findings.
const reviewDiff = agent({
model: "small",
instructions: p`Review ${p.bash("git diff -- .")} and return only the declared output.`,
output: s.object({
summary: s.string,
risk: s.enum("low", "medium", "high"),
findings: s.array(s.object({
file: s.path,
line: s.optional(s.int),
message: s.string,
})),
}),
});
export default reviewDiff;
```
## Construction rules
1. Import current APIs from `"rig"` once and define agents with `agent({ ... })` or workflows with `workflow({ ... })`.
2. Add a `// Agent role: ...` comment above each `agent()` and a `// Workflow role: ...` comment above each `workflow()`.
3. Omit `input`/`output` when free-form strings suffice; otherwise use explicit `s.*` schemas.

How to install
mdr add githubnext/rig/rig@sha256:f7c036c6c20496c6The line at the top of this page pins the label git:20261010.2be15ee, 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.
