## Description

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.

# 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
2. Authenticate  Sign in if needed, save state
3. Orient        Navigate to starting point, take initial snapshot
4. Explore       Systematically visit pages and test features
5. Document      Screenshot + record each issue as found
6. Wrap up       Update summary counts, close session
```

### 1. Initialize

```bash
mkdir -p {OUTPUT_DIR}/screenshots {OUTPUT_DIR}/videos
```

Copy the report template into the output directory and fill in the header fields:

```bash
cp {SKILL_DIR}/templates/dogfood-report-template.md {OUTPUT_DIR}/report.md
```

Start a named session:

```bash
agent-browser --session {SESSION} open {TARGET_URL}
agent-browser --session {SESSION} wait --load domcontentloaded
```

### 2. Authenticate

If the app requires login:
