Google Docs bulk comment poster

Post N anchored Google Docs comments from a JSON plan. Each comment is attached to a unique substring of doc body text, optionally with @-mentions of collaborators. Uses the user's already-logged-in browser session via the chrome-cdp skill.

Break-even is around 5 comments — for fewer, type them directly in the doc.

Prerequisites

1. chrome-cdp skill installed; the wrapper auto-discovers cdp.mjs (or set $CDP_BIN).
2. Chrome / Brave / Edge running with remote debugging enabled.
3. Google Doc tab open in that browser, logged in, with comment permission on the doc.
4. Node.js 22+ (uses built-in WebSocket / Unix-socket APIs).

Usage

# 1. find the doc tab
