Systematically explore and test a web application to find bugs, UX issues, and other problems. Use when asked to "dogfood", "QA", "exploratory test", "find issues", "bug hunt", "test this app/site/platform", or review the quality of a web application. Produces a structured report with full reproduction evidence -- step-by-step screenshots, repro videos, and detailed repro steps for every issue -- so findings can be handed directly to the responsible teams.
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
# Dogfood
Systematically explore a web application, find issues, and produce a report with full reproduction evidence for every finding.
## Setup
Only the **Target URL** is required. Everything else has sensible defaults -- use them unless the user explicitly provides an override.
| Parameter | Default | Example override |
|-----------|---------|-----------------|
| **Target URL** | _(required)_ | `vercel.com`, `http://localhost:3000` |
| **Session name** | Slugified domain (e.g., `vercel.com` -> `vercel-com`) | `--session my-session` |
| **Output directory** | `./dogfood-output/` | `Output directory: /tmp/qa` |
| **Scope** | Full app | `Focus on the billing page` |
| **Authentication** | None | `Sign in to user@example.com` |
If the user says something like "dogfood vercel.com", start immediately with defaults. Do not ask clarifying questions unless authentication is mentioned but credentials are missing.
Always use `agent-browser` directly -- never `npx agent-browser`. The direct binary uses the fast Rust client. `npx` routes through Node.js and is significantly slower.
## Workflow
```
1. Initialize Set up session, output dirs, report file

The line at the top of this page pins the label git:20260514.9ab716b, 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.
