Competitor Price Tracker AI Agent

What this agent does

Pricing changes are exactly the kind of competitive signal that matters a lot and gets noticed late, because nobody's job is to refresh five pricing pages every week. This agent checks your named competitors' pricing pages on a schedule, diffs them against the last known version, and alerts you the moment something changes.

1. pricing-page-snapshotter — fetches each configured competitor's pricing page and extracts the structured pricing data (tiers, prices, included features).
2. price-diff-alerter — compares the new snapshot against the last saved one, and if anything changed (a price moved, a tier was added/removed, a feature shifted tiers), writes a plain-language summary of exactly what changed and sends it to your configured channel.

Every run saves the snapshot regardless of whether a change was found, building a full pricing-history archive per competitor over time.

Requirements

• Runs entirely on free, built-in fetch/browse tools — no paid price-monitoring or scraping API required.
• Works on Claude AI (Claude Code, or claude.ai with code execution) and on Zo Computer natively.
• Some pricing pages render prices via JavaScript — for those, the package includes notes on using a browser-capable fetch rather than a plain HTTP request.

Setup

1. Unzip the package into your workspace, keeping the folder structure intact.
2. Edit config/tracked-competitors.md with each competitor's pricing page URL and a name label.
3. Run the starter prompt in starter-prompts.md to take the first snapshot of all tracked pages (this always reports "baseline saved", not a change).
4. Schedule automation-prompt.md weekly — pricing rarely changes more often than that, and daily checks mostly just burn requests.
