signals-scout-experiments

Signals scout for PostHog A/B experiments. Watches running experiments for validity threats — sample ratio mismatch, contamination, exposure stalls, mid-run flag mutations — and lifecycle drift.

Compatibility

PostHog Signals agent (Claude sandbox). Read-only analytics + signal_scout_internal:write (scratchpad) + signal_scout_report:write (report channel), plus the experiments, feature-flag, and analytics tools in the MCP tools section.
