Checklist
Testing
Point an independent agent at the skill and give it a realistic prompt that does not name the tool, then confirm it (a) discovers your new guide by following the skill's own links and (b) gives accurate guidance.
In Cursor/Claude Code: install the skill (tools/install --target --domain performance) or point the agent at this repo, then ask a triggering prompt and watch which files it opens.
Triggering prompts to use:
"MetaMask Mobile feels janky on a low-end Android device. I want to watch live FPS/CPU/RAM while I reproduce the jank, without adding code. What tool and workflow?"
"How do I profile a release build of MetaMask Mobile on-device for performance?"
Pass criteria: it reaches references/js-flashlight.md by following links (not by keyword-searching), and returns the flashlight measure → Auto Detect → Start Measuring → live vitals flow.
