JB Chrome MCP

Private skill for using Chrome DevTools MCP through mcporter against the user's existing Chrome session.

This skill defines JB-specific rules, bootstrap, safety, and recovery workflow only. For the full upstream tool catalog and exact arguments, read references/chrome-devtools-mcp-tool-reference.md instead of duplicating it here.

Hard rule: reattach to the existing Chrome profile only. Do not silently switch to isolated Chrome, Playwright, Puppeteer, the Codex in-app browser, AppleScript, osascript, GUI scripting, or macOS open for browser control unless the user explicitly asks for an isolated/new browser.

Screenshot/live UI bugs require this existing-Chrome path. curl, source inspection, Worker smoke tests, or local Playwright are supporting proof only; do not treat them as equivalent when the user showed a rendered browser problem or the page may depend on login/profile state.
