posthog-analyst

Analyze pi agentic conversations, errors, and misalignments using PostHog MCP. Queries $ai_generation, $ai_span, $ai_trace events, segments by model, detects failure patterns, cross-references the wiki's model-adaptive harness research, and generates model-specific recommendations filed to the wiki. Use this skill when the user wants to analyze agent performance, understand where the harness breaks per model, audit LLM errors or tool failures, improve model profiles based on real data, or run a postmortem on agentic sessions.
