What is querying-posthog-data?

Required reading before writing any HogQL/SQL or calling execute-sql against PostHog. Use whenever the user wants to search, find, or do complex aggregations PostHog entities (insights, dashboards, cohorts, feature flags, experiments, surveys, hog flows, data warehouse, persons, etc.) and query analytics data (trends, funnels, retention, lifecycle, paths, stickiness, web analytics, error tracking, logs, sessions, LLM traces). Also the first stop for a governed business number (MRR, activation, revenue): check the semantic layer (canonical metrics in system.information_schema.metrics) for an approved definition before deriving from raw events. Covers HogQL syntax differences from ClickHouse SQL, system table schemas (system.*), available functions, query examples, and the schema-discovery workflow.

Querying data in PostHog

The guidelines contain the same instructions as posthog:execute-sql. If you've already read posthog:execute-sql, you don't need to read them again.

When to use this skill

Finding a specific PostHog entity

When the user wants to find a specific entity created in PostHog (insights, dashboards, cohorts, feature flags, experiments, surveys, hog flows, data warehouse items, etc.), or when a list/search tool returns too many results to narrow down:

  1. Read the appropriate schema reference under Data Schema to understand the entity's table and columns.
  2. Use posthog:execute-sql to query the system table and find the matching entity (typically returning its ID).
  3. Use the dedicated read tool for that entity type (e.g. posthog:insight-get, posthog:dashboard-get) to retrieve the full entity by ID.

Don't try to reconstruct the entity from SQL — execute-sql is for discovery, the read tool is for retrieval.
