Turn your photos and shopping order screenshots into a structured, searchable JSON wardrobe database with AI vision and automated linting.
Review a database schema, queries, or migration for the mistakes that get expensive in production — bad table design, missing or wrong indexes, slow and N+1 queries, SQL injection, and migrations that lock or break prod. Engine-aware (PostgreSQL, MySQL, SQLite, SQL Server), it runs an ordered review and returns a PASS/REVIEW/BLOCK verdict with prioritized fixes. Schema mistakes are the most expensive kind — this catches them before they ship.
Plan, review, and execute safe database migrations with automatic rollback plans, backfill strategies, and zero-downtime sequencing.

Clean messy tabular data with a profile-first workflow, audit logs, and reproducible pandas scripts.
Produces a Redis caching design — cacheability assessment, invalidation strategy, TTL and jitter design, and stampede protection for given data patterns. Use when the user says "design our caching layer", "fix cache invalidation", "prevent a thundering herd", "pick a Redis data structure", or "set our cache TTL strategy". Do not use when the request is database schema or index design, not caching.
Audit local dbt SQL and YAML for missing model tests, source freshness and test gaps, likely-key coverage, missing model descriptions, SELECT *, and raw table references. Get severity-ranked findings plus starter tests YAML for model/key gaps without running dbt or querying a warehouse.
Each skill on this page is a SKILL.md file built for data engineering work and confirmed to run in Grok. Install one into ~/.grok/skills/, start a new session, and Grok follows the workflow the creator encoded instead of improvising from a short prompt.
Listings are ranked by installs, upvotes and reviews, so what surfaces first is what other Grok users actually keep. Free and paid skills compete on the same page, and every listing shows its security scan result before you download anything.
