From 3d8c4f8542e86924a56f76f0a5061d92c363152f Mon Sep 17 00:00:00 2001 From: Aleksandar Grbic Date: Sun, 27 Sep 2026 11:17:46 +0200 Subject: [PATCH 1/3] feat(research): SearXNG-first search with result routing + Hacker News and Stack Exchange readers - web_search: up to 5 phrasings per call (round-robin merged, deduplicated), recency 'week', topic-aware 'already read' flags, and every result names its reader (reddit_thread / hn_thread / se_question / web_fetch) - web_fetch: with a topic, Reddit/HN/SE URLs are read by their site tool, and ordinary pages are logged in notes//sources.md and not re-read - site plugins gain a 'direct' transport for public JSON APIs (no browser): pacing + 429/5xx backoff, host allowlist, https only - Hacker News plugin (Algolia API): hn_search, hn_thread (whole tree in one request) - Stack Exchange plugin (API v2.3): se_search (any site), se_question (question + answers, accepted first, code kept); honours the API backoff, reports low quota, optional TSFORGE_STACKEXCHANGE_KEY - a 'Finding and reading sources' playbook for research sessions - docs: integrations/research-sources, web-tools, flags, where-to-change --- apps/docs/astro.config.mjs | 1 +
