HN Digest

Command format

Interpret a user message that starts with hn as a request for a Hacker News front-page digest.

Supported forms:

• hn → default 5 posts

• hn <n> → n posts

• hn <topic> → filter/boost by topic

• hn <n> <topic> → both

• If the user asks for “more” after already seeing some (e.g. “show me top 10–15 since we already did top 10”), treat it as an offset request and use --offset (e.g. offset 10, count 10).

Topics:

• tech (default)

• health

• hacking

• life / lifehacks

Output requirements

• Do not send any extra commentary/preamble/epilogue.

• Send results as individual messages.

• Each post message must be exactly:

  • first line: the post title
  • second line: <age> · <commentCount> comments (age like 45m ago, 6h ago, 3d ago)
  • third line: the Hacker News comments link (https://news.ycombinator.com/item?id=...)

• After the post messages, send one final message that is the generated image.

  • If the chat provider requires non-empty text for media, use a minimal caption ..

• Hard exclude crypto.

Procedure

1. Parse n and topic from the user message.

2. Fetch + rank items:

   • Run node skills/hn-digest/scripts/hn.mjs --count <n> --offset <offset> --topic <topic> --format json.
   • Default offset is 0 unless the user explicitly asks for “more/next” after a previous batch.

3. Send results as N individual messages in the required 3-line format.

4. Then generate a delightful mood image via Nano Banana, inspired by the posts you just sent:

   • Use skills/hn-digest/scripts/mood_prompt.mjs to build a prompt from the JSON items.
   • Add 3–4 subtle Easter eggs derived from the post themes (no text/logos; keep it fun).
   • Generate and attach the image by running:
     • skills/hn-digest/scripts/generate_mood_nano_banana.sh ./tmp/hn-mood/hn-mood.png <topic> <n> <offset>
   • Send the generated image as one additional message.

If fetching/ranking fails or returns 0 items:

• Use https://news.ycombinator.com/ in the browser tool, pick N non-crypto items by judgment, and send them in the same 3-line format.

• Still generate a mood image (general “HN tech deep dives” vibe) with a banana Easter egg.
