README

Sandboxed Issue Triage Agent

This demo app shows how to use AI SDK 7 `HarnessAgent` with Vercel Sandbox to investigate third-party reproduction repositories without running unknown code on a maintainer laptop.

The app accepts:

A public GitHub repository URL
An issue report
An optional failing command
A harness adapter choice

It creates a harness-backed session in Vercel Sandbox, streams the investigation, and returns a maintainer-ready reproduction report.

The default form values point at this public repro repository:

https://github.com/vercel-labs/harness-triage-repro-bugs
Default issue: https://github.com/vercel-labs/harness-triage-repro-bugs/issues/2
Alternate issue: https://github.com/vercel-labs/harness-triage-repro-bugs/issues/1

Why this demo exists

The point is not that an agent can read a repository. A developer can already do that locally. The point is that a product can safely investigate unknown code on behalf of a team, while keeping the harness swappable.

Run locally

pnpm install
pnpm dev

Open `http://localhost:3000`.

You will need AI SDK 7 canary harness packages, Vercel Sandbox credentials, and Vercel AI Gateway credentials available to your local environment. The demo intentionally routes harness model access through AI Gateway, not provider-specific API keys.

For local development:

vercel link
vercel env pull .env.local

Required environment:

VERCEL_OIDC_TOKEN=...

Optional overrides:

AI_GATEWAY_API_KEY=...
AI_GATEWAY_BASE_URL=https://ai-gateway.vercel.sh

`lib/harness-agent.ts` passes Gateway auth into every harness adapter. It uses `AI_GATEWAY_API_KEY` when present and falls back to `VERCEL_OIDC_TOKEN` for local Vercel-authenticated development.

The package names follow the current HarnessAgent canary proposal:
