Claude Code skills for Analytics & Data engineers working with dbt and Snowflake

Altimate Data Skills is a collection of Claude Code skills that encode the workflows and best practices of experienced analytics engineers. These skills transform Claude from a code generator into a capable data engineering assistant.

Key Results

• 53% accuracy on ADE-bench (43 real-world dbt tasks)
• 3x improvement on model creation tasks vs baseline
• 84% pass rate on Snowflake query optimization (62 TPC-H queries, 1TB dataset)
• 3.6x better performance gains vs baseline (16.8% avg improvement vs 4.7%)
• Skills that teach Claude how to work, not just what to write

Snowflake Skills

Skill	Purpose	Key Behaviors
finding-expensive-queries	Cost analysis	Find and rank queries by cost/time/data scanned
optimizing-query-by-id	Performance tuning	Optimize using query ID from history
optimizing-query-text	Performance tuning	Profile query → Identify bottlenecks → Apply patterns

altimate-code Delegation

Skill	Purpose	Key Behaviors
altimate-code	Hand off data tasks to altimate-code	Verify install → Invoke altimate-code run --yolo non-interactively → Read output file → Summarize for user

Use this skill when a task needs altimate-code's wired-up warehouse tools, column lineage, multi-step data exploration, or its 100+ specialized data tools.

Requires altimate-code: npm install -g altimate-code (Node 20+). Docs: docs.altimate.sh · Source: AltimateAI/altimate-code. The skill will detect a missing install and surface the exact command to the user.
