In detail / 03 · RADAR

Turn one piece of research into a standing watch.

Say what to watch, how often to check, and what change is worth an alert. When something changes, you get the time, the change and the evidence; when nothing does, the scan record is still there — quiet is not the same as idle.

  1. A task in one sentenceDescribe the question to watch; the agent drafts a name and schedule for you to confirm. Example tasks can be used as-is.
  2. Schedules with reasonsHow often to check follows the nature of the task: weekly in earnings season, per filing cycle for 13F — the reasoning is stated.
  3. Hits carry evidenceWhen a watch fires you get the full trace: when it changed, what changed, and where the material is.
  4. No change, still recorded“Scanned, nothing changed” is also a result — every run is on record, so nothing silently stops.
  5. You decide what to watchA company, a theme, or conditions you write yourself — up to 20 tasks.
