Browser Agent Debug Checklist use cases
Use this when an AI agent cannot see the browser, loses login state, fails CDP connection, or gets blocked by captcha.
Scope and privacy
The checker runs locally in this browser and does not upload the pasted input. Remove secrets before pasting. Results are static evidence from the supplied text, not proof of live server behavior, security, compatibility, or approval.
Verification workflow
- Use a redacted, minimal failing example.
- Fix definite syntax or metadata errors first.
- Test the real endpoint with official inspectors and representative tasks.
- Add a regression test before publishing.
