Compatibility is declared by the source manifest. End-to-end runtime verification is coming, see below.
We're building live execution health for every listing: tool-call success rate, median latency, uptime, and last-checked timestamps, measured, not self-reported. It isn't live yet, so we don't show numbers we can't stand behind.

Setup
Before first use, install dependencies:
npm install --prefix skills/browserStart Chrome
./skills/browser/scripts/start.js # Fresh profile
./skills/browser/scripts/start.js --profile # Copy your profile (cookies, logins)Start Chrome on :9222 with remote debugging.
Navigate
./skills/browser/scripts/nav.js https://example.com
./skills/browser/scripts/nav.js https://example.com --newNavigate current tab or open new tab.
Evaluate JavaScript
./skills/browser/scripts/eval.js 'document.title'
./skills/browser/scripts/eval.js 'document.querySelectorAll("a").length'Execute JavaScript in active tab (async context).
IMPORTANT: The code must be a single expression or use IIFE for multiple statements:
- Single expression:
'document.title' - Multiple statements:
'(() => { const x = 1; return x + 1; })()' - Avoid newlines in the code string - keep it on one line
Screenshot
./skills/browser/scripts/screenshot.jsScreenshot current viewport, returns temp file path.
Pick Elements
./skills/browser/scripts/pick.js "Click the submit button"Interactive element picker. Click to select, Cmd/Ctrl+Click for multi-select, Enter to finish.
Workflow
- Start Chrome with
start.js --profileto mirror your authenticated state. - Drive navigation via
nav.js https://target.appor open secondary tabs with--new. - Inspect the DOM using
eval.jsfor quick counts, attribute checks, or extracting JSON payloads. - Capture artifacts with
screenshot.jsfor visual proof orpick.jswhen you need precise selectors or text snapshots.
Usage Notes
- Start Chrome first before using other tools
- The
--profileflag syncs your actual Chrome profile so you're logged in everywhere - JavaScript evaluation runs in an async context in the page
- Pick tool allows you to visually select DOM elements by clicking on them
