There was a problem hiding this comment.
I'm thinking the bugzilla attachment link to the script (i.e. https://bug1952830.bmoattachments.org/attachment.cgi?id=9623008) could also be passed by the caller as an additional parameter instead of asking the agent to locate it.

This agent has the same browser / MCP setup as the autowebcompat-repro agent.
I'm going to move the browser installation and MCP servers into a shared directory in a separate PR.
The agent has 3 tasks:
DiagnosisPlan
Creates a plan for diagnosis, picks the browser channel to install, locates the Puppeteer script if available, records url and STR.
ReproScript (If Puppeteer script exists and passes in Chrome/ fails in Firefox this step is skipped)
If the script doesn't exist or doesn't work as expected, it tries to reproduce the bug again and create the script.
Diagnosis
Does root-cause diagnosis, creates minimal testcase.
I've added reproduction and puppeteer script creation mainly so we could use it for opt-in diagnosis on bugzilla bugs that don't have prior runs of the repro agent. But we can certainly make it diagnosis only and run the repro agent first when diagnosis is requested.
Also when sites change and previously created puppeteer script does not work, this agent would create it's own revised version of the script and have one more attempt to reproduce the bug, so it might be good to keep ReproScript anyway.
