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.

Querying analytics data

When the user wants analytics data (trends, funnels, retention, paths, sessions, LLM traces, web analytics, errors, logs, etc.) and the existing insight schemas don't fit the request:
