Daily Brief

A short, dated, source-linked digest — not a feed.

Topics: {{topics}} Horizon: {{horizon}}

Procedure

1. One search per source, not one per topic. A generic search.web on a topic returns the same three aggregator posts every day. Query sources separately: Hacker News, GitHub Trending, Hugging Face Papers, arXiv, TechCrunch, Reuters, and the primary sites of whoever is central to the topic.

2. Date-gate hard. Anything outside {{horizon}} is dropped, however good it is — then report how many you dropped. "14 results, 9 outside the window" tells the reader whether the topic is quiet or whether the search was bad, and those call for different responses.

3. Rank by consequence, not recency. A three-hour-old release note that changes someone's plans outranks a one-hour-old opinion piece about it. Recency is the filter; it is not the sort.

4. Three bullets per topic, maximum. A brief that takes ten minutes to read is not a brief, and it will not be read tomorrow.

5. Say what did not happen. When a topic was quiet, write one line saying so. An empty section reads as a broken tool; "no movement on the ruling, day 4" is information, and is usually why the reader asked.

6. Carry the thread. memory.save the running state per topic where it is available, so tomorrow can open with what changed instead of restating the world.

7. Publish with artifact.deploy if available, and return the link alongside the text.

Output

Per topic: a heading, up to three bullets, each carrying a date and a link to the primary source. Then the dropped-result count, and the link if you published one.

Notes

• Cite what the aggregator linked to, never the aggregator. "Hacker News says" is not a source.
• Dates on everything. A brief whose reader cannot tell whether a claim is a day or a year old is worse than no brief.
• International sources only. This pack targets the global surface — the sources above, plus a topic's own primaries. Region-specific aggregators are deliberately out of scope; adding them would quietly change what the pack is for.
