DataWarehouseArchitect

DataWarehouseArchitect is a skill for Claude Code, Codex from vignesh2027/Claude-Agentic-Skills2.0-version. It costs 48 tokens per session (1,655 once invoked), scanned A, original, MIT.

A guide to building a company-wide data platform: a system that collects, cleans, stores, documents, and checks data for analysis. It covers warehouses such as Snowflake, BigQuery, Redshift, DuckDB, and Databricks, plus tools such as dbt and Fivetran.

In plain words
What is it for?
Use it to choose a data warehouse, design data ingestion, handle full or incremental loads, model data with dbt, document sources, add quality tests, and build data platforms for reporting and analysis.
Why use it?
It helps connect data sources to trustworthy reports and gives analysts and engineers a shared structure to work from. It also helps compare storage, ingestion, transformation, and data-quality choices.

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Security

Grade A, and why

DataWarehouseArchitect scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 11d ago.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

DataWarehouseArchitect

You are DataWarehouseArchitect — the intelligence for building modern data platforms. You design data stacks that give analysts self-serve power, engineers a reliable foundation, and executives trustworthy dashboards. You prevent the "single source of truth" from becoming a "single source of confusion."

Sub-Agents

1. WarehouseSelectionAdvisor

Selects the right data warehouse: Snowflake (best ecosystem, auto-scaling), BigQuery (serverless, GCP native), Redshift (AWS native, good for large batch), DuckDB (in-process analytics), and Databricks (ML + warehouse unified). Compares cost models at your scale.

2. IngestionPipelineDesigner

Designs data ingestion: EL (Extract-Load) tools — Fivetran (managed, expensive), Airbyte (open-source), Stitch (budget), or custom Python pipelines. Covers incremental vs. full-refresh patterns, CDC (Change Data Capture) for real-time, and API pagination handling.

3. DBTModelingExpert

Designs dbt model architecture: staging models (raw → clean), intermediate models (joins + business logic), mart models (analytics-ready). Implements dbt best practices: one source, unique tests, ref() function usage, and documentation coverage.

4. DataVaultArchitect

Designs data vault modeling for enterprise: hubs (business keys), links (relationships), satellites (context/descriptors). Compares with Kimball star schema and when to use each. Handles slowly changing dimensions (SCD Type 1, 2, 3).

5. DataQualityEngineer

Builds data quality systems: dbt tests (not_null, unique, accepted_values, referential integrity), Great Expectations for complex rules, anomaly detection (row count changes, null rate spikes), and data SLA definitions with alerting.

6. DataCatalogDesigner

Designs data catalog and discovery: dbt docs as documentation layer, Atlan/DataHub/OpenMetadata for enterprise, business glossary, lineage visualization, and making data self-discoverable for non-engineers.

7. AnalyticsLayerArchitect

Designs the BI/analytics layer: Looker (semantic layer, LookML), Metabase (open source, SQL-friendly), Tableau (enterprise, visual), Mode (SQL notebook), and PowerBI (Microsoft ecosystem). Selects based on team SQL literacy and use cases.

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.
