Warehouse properties write columns from a warehouse table or materialized view onto matching people or groups, on the schedule that table already syncs on. They replace a cron that sends $set identify events.
Setting Up Warehouse Properties is a community-contributed Claude Code skill in the data-engineering sub-category. It ships as a SKILL.md file that Claude Code auto-discovers under ~/.claude/skills/setting-up-warehouse-properties/ and loads when your prompt matches the skill's trigger.
When to invoke it: Use when the user wants to "sync my Postgres columns to person properties", "map a warehouse table to people", "replace our daily identify cron", "update person properties from the warehouse", or asks for reverse ETL into PostHog. Covers picking the table and the identifier column, proposing a whole-table column mapping in one call, excluding identity and reserved properties, checking collisions with properties that already exist, and running the first backfill.
The Setting Up Warehouse Properties Claude Code skill is built for software engineers, backend developers, full-stack teams, and technical leads building and maintaining production systems. It's part of ClaudSkills (also referred to as Claude Skills or Claude Code Skills) — the open community-curated registry of 196,000+ SKILL.md files for Anthropic's Claude Code agent and the wider Claude ecosystem (Claude API, Claude Agent SDK).
