Pull request overview
Adds three new narrowly scoped, browser-focused investigation agents to the repository’s agent catalog to support runtime evidence-based workflows (performance diagnosis, regression triage, and accessibility runtime testing), and updates the agents README so they appear in the published list.
Changes:
- Added
Frontend Performance Investigatoragent for DevTools-driven performance investigations (CWV/Lighthouse/trace-based analysis). - Added
DevTools Regression Investigatoragent for reproducing browser regressions and collecting console/network evidence. - Added
Accessibility Runtime Testeragent for keyboard/focus/runtime accessibility validation, plus regenerateddocs/README.agents.mdto include all three.

Pull Request Checklist
npm startand verified thatREADME.mdis up to date.stagedbranch for this pull request.Description
Adds three new specialized browser-focused agents for runtime investigation workflows:
frontend-performance-investigator.agent.mddevtools-regression-investigator.agent.mdaccessibility-runtime-tester.agent.mdThese agents are intentionally narrower than existing general browser/testing/debug agents and focus on evidence-backed runtime analysis with Chrome DevTools MCP-
style workflows.
Summary of each agent:
Frontend Performance Investigator: runtime web-performance diagnosis for Core Web Vitals, Lighthouse regressions, layout shifts, long tasks, and slow networkpaths.
DevTools Regression Investigator: browser regression reproduction and triage for broken user flows, with console/network evidence and likely root-causenarrowing.
Accessibility Runtime Tester: runtime accessibility validation for keyboard flows, focus management, dialog behavior, form errors, and browser-observed WCAGissues.
This also regenerates
docs/README.agents.mdso the new agents appear in the catalog.Type of Contribution
Additional Notes
These are not intended to be generic browser testers.
The goal is to add more focused runtime investigation agents in areas that are valuable to users and explicitly in scope for the repository:
I tried to keep overlap low by making each agent centered on a distinct investigation workflow rather than a general-purpose testing persona.
