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
mkdir -p {OUTPUT_DIR}/screenshots {OUTPUT_DIR}/videos
Copy the report template into the output directory and fill in the header
fields:
cp {SKILL_DIR}/templates/dogfood-report-template.md {OUTPUT_DIR}/report.md
Start a named session:
agent-browser --session {SESSION} open {TARGET_URL}
agent-browser --session {SESSION} wait --load networkidle
2. Authenticate
If the app requires login:
agent-browser --session {SESSION} snapshot -i
agent-browser --session {SESSION} fill @e1 "{EMAIL}"
agent-browser --session {SESSION} fill @e2 "{PASSWORD}"
agent-browser --session {SESSION} click @e3
agent-browser --session {SESSION} wait --load networkidle
For OTP/email codes: ask the user, wait for their response, then enter the code.
After successful login, save state for potential reuse:
agent-browser --session {SESSION} state save {OUTPUT_DIR}/auth-state.json
3. Orient
Take an initial annotated screenshot and snapshot to understand the app
structure:
agent-browser --session {SESSION} screenshot --annotate {OUTPUT_DIR}/screenshots/initial.png
agent-browser --session {SESSION} snapshot -i
Identify the main navigation elements and map out the sections to visit.
4. Explore
Read references/issue-taxonomy.md for the full
list of what to look for and the exploration checklist.
Strategy -- work through the app systematically:
- Start from the main navigation. Visit each top-level section.
- Within each section, test interactive elements: click buttons, fill forms,
open dropdowns/modals.
- Check edge cases: empty states, error handling, boundary inputs.
- Try realistic end-to-end workflows (create, edit, delete flows).
- Check the browser console for errors periodically.
At each page:
agent-browser --session {SESSION} snapshot -i
agent-browser --session {SESSION} screenshot --annotate {OUTPUT_DIR}/screenshots/{page-name}.png
agent-browser --session {SESSION} errors
agent-browser --session {SESSION} console
Use your judgment on how deep to go. Spend more time on core features and less
on peripheral pages. If you find a cluster of issues in one area, investigate
deeper.
5. Document Issues (Repro-First)
Steps 4 and 5 happen together -- explore and document in a single pass. When you
find an issue, stop exploring and document it immediately before moving on. Do
not explore the whole app first and document later.
Every issue must be reproducible. When you find something wrong, do not just
note it -- prove it with evidence. The goal is that someone reading the report
can see exactly what happened and replay it.
Choose the right level of evidence for the issue:
Interactive / behavioral issues (functional, ux, console errors on action)
These require user interaction to reproduce -- use full repro with video and
step-by-step screenshots:
- Start a repro video before reproducing:
agent-browser --session {SESSION} record start {OUTPUT_DIR}/videos/issue-{NNN}-repro.webm
- Walk through the steps at human pace. Pause 1-2 seconds between actions
so the video is watchable. Take a screenshot at each step:
agent-browser --session {SESSION} screenshot {OUTPUT_DIR}/screenshots/issue-{NNN}-step-1.png
sleep 1
sleep 1
agent-browser --session {SESSION} screenshot {OUTPUT_DIR}/screenshots/issue-{NNN}-step-2.png
sleep 1
- Capture the broken state. Pause so the viewer can see it, then take an
annotated screenshot:
sleep 2
agent-browser --session {SESSION} screenshot --annotate {OUTPUT_DIR}/screenshots/issue-{NNN}-result.png
- Stop the video:
agent-browser --session {SESSION} record stop
- Write numbered repro steps in the report, each referencing its screenshot.
Static / visible-on-load issues (typos, placeholder text, clipped text, misalignment, console errors on load)
These are visible without interaction -- a single annotated screenshot is
sufficient. No video, no multi-step repro:
agent-browser --session {SESSION} screenshot --annotate {OUTPUT_DIR}/screenshots/issue-{NNN}.png
Write a brief description and reference the screenshot in the report. Set
Repro Video to N/A.
For all issues:
-
Append to the report immediately. Do not batch issues for later. Write
each one as you find it so nothing is lost if the session is interrupted.
-
Increment the issue counter (ISSUE-001, ISSUE-002, ...).
6. Wrap Up
Aim to find 5-10 well-documented issues, then wrap up. Depth of evidence
matters more than total count -- 5 issues with full repro beats 20 with vague
descriptions.
After exploring:
- Re-read the report and update the summary severity counts so they match the
actual issues. Every
### ISSUE- block must be reflected in the totals.
- Close the session:
agent-browser --session {SESSION} close
- Tell the user the report is ready and summarize findings: total issues,
breakdown by severity, and the most critical items.
Guidance
- Repro is everything. Every issue needs proof -- but match the evidence to
the issue. Interactive bugs need video and step-by-step screenshots. Static
bugs (typos, placeholder text, visual glitches visible on load) only need a
single annotated screenshot.
- Verify reproducibility before collecting evidence. Before recording video
or taking screenshots, verify the issue is reproducible with at least one
retry. If it can't be reproduced consistently, it's not a valid issue.
- Don't record video for static issues. A typo or clipped text doesn't
benefit from a video. Save video for issues that involve user interaction,
timing, or state changes.
- For interactive issues, screenshot each step. Capture the before, the
action, and the after -- so someone can see the full sequence.
- Write repro steps that map to screenshots. Each numbered step in the
report should reference its corresponding screenshot. A reader should be able
to follow the steps visually without touching a browser.
- Use the right snapshot command.
snapshot -i — for finding clickable/fillable elements (buttons, inputs,
links)
snapshot (no flag) — for reading page content (text, headings, data lists)
- Be thorough but use judgment. You are not following a test script -- you
are exploring like a real user would. If something feels off, investigate.
- Write findings incrementally. Append each issue to the report as you
discover it. If the session is interrupted, findings are preserved. Never
batch all issues for the end.
- Never delete output files. Do not
rm screenshots, videos, or the report
mid-session. Do not close the session and restart. Work forward, not backward.
- Never read the target app's source code. You are testing as a user, not
auditing code. Do not read HTML, JS, or config files of the app under test.
All findings must come from what you observe in the browser.
- Check the console. Many issues are invisible in the UI but show up as JS
errors or failed requests.
- Test like a user, not a robot. Try common workflows end-to-end. Click
things a real user would click. Enter realistic data.
- Type like a human. When filling form fields during video recording, use
type instead of fill -- it types character-by-character. Use fill only
outside of video recording when speed matters.
- Pace repro videos for humans. Add
sleep 1 between actions and sleep 2
before the final result screenshot. Videos should be watchable at 1x speed --
a human reviewing the report needs to see what happened, not a blur of instant
state changes.
- Be efficient with commands. Batch multiple
agent-browser commands in a
single shell call when they are independent (e.g.,
agent-browser ... screenshot ... && agent-browser ... console). Use
agent-browser --session {SESSION} scroll down 300 for scrolling -- do not
use key or evaluate to scroll.
