Build reusable dimension / lookup tables for a star schema — country/region, timezone, currency, date, plan/product, and other descriptive attributes — on either PostHog data-warehouse views (HogQL) or an external dbt project. Use when the user wants to model dimension tables, lookup tables, a star schema, conformed dimensions, or wants to enrich events/revenue/usage with country, region, timezone, plan, or currency attributes without repeating JOINs. Covers sourcing the dimension data (upload, warehouse source, or derive from events), shaping it into an aliased one-row-per-entity view (optionally materialized on a slow schedule since dimensions change rarely), and attaching it to facts via a saved or person join so its columns read as native fields. Key rule: for currency use the built-in convertCurrency() instead of a hand-rolled rate table. Read modeling-warehouse-foundations first; dimensions here are reused by the revenue, conversion, activation, and product-usage modeling skills.

From the source SKILL.md

Dimensions are the descriptive tables (dim_country, dim_plan, dim_date) that fact tables join to for slicing. This skill builds them once, cleanly, so every other model reuses them instead of re-deriving lookups. Read modeling-warehouse-foundations first (joins + convertCurrency() live there). Catalog of common dimensions: [references/dimension-catalog.md](references/dimension-catalog.md); recipes in [references/posthog/](references/posthog/) and [references/dbt/](references/dbt/).

What this skill does

Modeling Dimension Tables is a community-contributed Claude Code skill in the product-misc sub-category. It ships as a SKILL.md file that Claude Code auto-discovers under ~/.claude/skills/modeling-dimension-tables/ and loads when your prompt matches the skill's trigger.
