Summary by cubic

Turns the HN monitor into an agentic radar that scans Front Page, Show HN, and New, ranks stories by agent-infra relevance, and posts a compact Slack header with a rich threaded digest. Adds Slack @mention, Telegram, and relay Q&A that hydrates live HN details and top comments.

• New Features

  • Multi-feed scan with agent-infra relevance scoring and deduped feed provenance.
  • Slack-first digest: compact header + threaded body with category, points/comments, source, and “why it matters”.
  • Q&A: reply to Slack thread mentions, Telegram, and relay DMs; hydrates story details and top HN comments before answering.
  • Deterministic evals: HTTP fixtures for HN feeds/items; npm run evals:hn and npm run test:hn.
  • Read-only live preview: npm run preview:hn (fetches + formats, no model/memory/delivery).
  • Resilient delivery: pending-thread recovery, improved memory records, and LLM fallback.
  • Persona updates: clearer system prompt; Slack app_mention trigger; configurable LOOKBACK_HOURS and MAX_STORIES.

• Migration

  • Configure SLACK_CHANNEL and/or TELEGRAM_CHAT. Optional: tune TOPICS; new LOOKBACK_HOURS (default 24) and MAX_STORIES (default 8).
  • Inner loop: npm run test:hn, npm run evals:hn, npm run preview:hn.
  • Mac mini gate: deploy with SANDBOX_PROVIDER=local and LOCAL_SANDBOX_URL (Tailscale Funnel); trigger via agentworkforce trigger hn-monitor and tail logs.
