⚡ Search Sweep

// scripts/searchSweep.js
// Delete, like, repost, or reply to every post an X search returns, e.g. from:you @someone
// Paste in DevTools console on x.com/search?q=...
// by nichxbt
//
// The use case that built it: "I replied to @someone 400 times over two years and I want
// every one of those replies gone." X gives you no bulk tool for that, but its search does
// find them: from:you @someone. This sweeps that result set and applies the action you pick.
//
//   https://x.com/search?q=from%3Ayou%20%40someone&src=typed_query&f=live
//
// Actions: delete (your own posts only), like, repost, reply. Delete is exclusive: a post
// you are about to remove is not one you also want to like.
//
// Two things about X search that this script works around, and you should know about:
//   1. Search returns a slice, not the whole set. One pass never finds everything.
//      CONFIG.passes re-runs the query and sweeps again until a pass finds nothing new.
//   2. The search index lags deletions by minutes. A post you just deleted can still be
//      listed. Every id is remembered, so a later pass skips it instead of erroring.
// Use &f=live (the Latest tab). Top ranking hides most of your older replies.
//
// AI replies from the console: x.com's Content-Security-Policy only lets the page reach a
// short list of hosts, and https://api.x.ai is on it. So provider 'xai' (Grok) works from
// the console with your xAI key. For OpenAI/Anthropic/OpenRouter/Ollama install the
// XActions browser extension (extension/) and set provider 'bridge'.
//
// A floating panel appears when you paste. Everything below can be changed there.
// Dry run is ON by default. Read one pass of the log, then turn it off.
//
// DELETION IS PERMANENT. Export your posts first with scripts/backupAccount.js.
