Description
Adds agent-agnostic guidance for this repo (AGENTS.md convention) plus a frontend skill for UI work.
AGENTS.md - a router pointing into .agents/ (task guides + personas), loaded on demand.
.agents/skills/heimdall-ui.md - the single source of truth for UI-only changes to the web app (web/): scope (what's in/out), repo orientation, local dev loop, the lint/type-check/build gate, real-browser verification, and accessibility/failure-handling rules. Includes a guard that the skill only acts on a requested change, not a standing "go find work" instruction.
.agents/personas/frontend-reviewer.md - a mindset profile to adopt for UI work.
Browser MCP handling
UI verification uses the chrome-devtools MCP. The guide never hardcodes the install command - it directs the agent to fetch the current per-client command from the official docs (ChromeDevTools/chrome-devtools-mcp) and register it per-user (try the official CLI first, fall back to writing the client's MCP config). Nothing MCP-specific is committed to the repo.
Notes
Vendor-neutral by design: knowledge lives in .agents/ (any agent/human reads it);
heimdall-ui skill in action (chrome-devtool-mcp allows the agent to access a chrome instance and run tools varying from taking screenshots to performance monitoring - 30+ tools)
