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:

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.

Parse n and topic from the user message.
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.
Send results as N individual messages in the required 3-line format.
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.
