Apache-2.0
An official Chrome DevTools for agents skill for problems with cookies, sessions and sign-in.
What the skill teaches
An official Chrome DevTools for agents skill for problems with cookies, sessions and sign-in. Using the Chrome DevTools MCP server, the agent reads Cookie and Set-Cookie headers from network requests, which is how it sees HttpOnly cookies that page scripts cannot reach, and reads other cookies from the page itself. The skill covers unexpected 401 and 403 responses, login redirects, sessions that expire early, SameSite, third-party and partitioned cookie warnings, and whether a site's cookie banner actually respects the visitor's consent choice.
Capabilities
- Inspect Cookie and Set-Cookie headers on requests
- Diagnose 401/403 errors and login redirects
- Check SameSite and third-party cookie warnings
- Test whether a cookie banner honours consent
