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 posts
• hn → filter/boost by topic
• hn → 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: · 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 --offset --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
• 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.
