I would define a watchlist before collection, then let the Agent gather broadly and rank with a consistent rule. Include your actual buyer segments, closest competitors, and the pricing, key capabilities, channels and positioning that affect a purchase decision. A homepage wording tweak matters only if it changes the promise or target buyer; even a price or feature announcement needs confirmation of launch status, region and applicable plan.
Keep an evidence log with competitor, before/after, first-seen date, original URL or screenshot, scope, confidence, likely impact and an owner for follow-up. Select three to five verified changes for the report. Each should answer: what changed, where is the evidence, which customer or decision could it affect, and what should we check or do next? Put unverified claims in a separate “to verify” section. If nothing material happened, say so rather than inventing five highlights.
A prompt for your Buda Agent: “Check this competitor watchlist weekly. Collect dated changes with primary links, rank by customer impact, action needed and evidence strength. Give me at most five important items with before/after and a proposed next check. Put uncertain or cosmetic changes in an appendix; do not infer a launch from marketing copy alone.” Is pricing, product capability or sales positioning most important for your team? The Chinese discussion covers the same rubric.
