What problem does it solve?
Aggregate traffic totals hide segment-level problems: one acquisition channel can collapse, UTM tagging can silently reclassify paid traffic into Direct, or a landing page's bounce rate can step up, all while the site's overall numbers look normal. This Skill continuously scouts PostHog web analytics data to surface exactly those segment-vs-aggregate divergences and authors actionable reports.
Core Features & Use Cases
- Channel divergence detection: Scores each
$channel_type against four seasonality-aligned windows (7/14/21/28 days back) using a median/MAD robust z-score, so a channel stepping away from its own baseline is caught while totals hold.
- Attribution breakage detection: Identifies paired opposite moves (e.g., Paid Search down while Unknown/Direct rises) and falling tagged-session share, pointing to UTM stripping or referrer propagation failures.
- Site-health monitoring: Watches per-host, ID-normalized entry paths for bounce-rate steps and traffic cliffs, plus 404/not-found event spikes with feeder-path attribution.
- Report authoring and dedupe: Authors or edits inbox reports end-to-end via the report channel, with scratchpad memory (
pattern:, noise:, dedupe:, report: keys) so recurring cadences and known issues are never re-filed.
- Use Case: A marketing team's consent banner starts stripping UTM parameters. The scout notices Paid Search sessions dropping while Direct rises by a matching amount, confirms tagged share fell, and files a P2 report naming the cause, the fix, and a success criterion.
Quick Start
Ask the agent to run a web analytics scout pass over the last 24 hours of PostHog sessions and report any channel, landing page, or 404 diverging from its own baseline.
