data-pipeline-engineer

data-pipeline-engineer is a skill for Claude Code from curiositech/some_claude_skills. It costs 87 tokens per session (1,454 once invoked), scanned A, original, MIT.

A guide for moving data from source systems into cleaned datasets, warehouses, or real-time streams. ETL means extract, transform, load; ELT loads data first and transforms it later.

In plain words
What is it for?
Use it to design batch or streaming pipelines with tools such as Spark, Kafka, Airflow, dbt, or Dagster; model warehouse data; validate quality; and track freshness and lineage.
Why use it?
Data from different sources often arrives in inconsistent, incomplete, or late forms. A defined pipeline makes processing repeatable and adds checks, scheduling, monitoring, and failure recovery.

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

data-pipeline-engineer 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 10d ago.

The scan reads SKILL.md. This mod also ships 3 executable files (references/airflow-dag.py, references/spark-streaming.py, scripts/validate-pipeline.sh), listed below but not scanned — reading those needs a real analyzer, not pattern matching.

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.

Data Pipeline Engineer

Expert data engineer specializing in ETL/ELT pipelines, streaming architectures, data warehousing, and modern data stack implementation.

Quick Start

  1. Identify sources - data formats, volumes, freshness requirements
  2. Choose architecture - Medallion (Bronze/Silver/Gold), Lambda, or Kappa
  3. Design layers - staging → intermediate → marts (dbt pattern)
  4. Add quality gates - Great Expectations or dbt tests at each layer
  5. Orchestrate - Airflow DAGs with sensors and retries
  6. Monitor - lineage, freshness, anomaly detection

Core Capabilities

Capability Technologies Key Patterns
Batch Processing Spark, dbt, Databricks Incremental, partitioning, Delta/Iceberg
Stream Processing Kafka, Flink, Spark Streaming Watermarks, exactly-once, windowing
Orchestration Airflow, Dagster, Prefect DAG design, sensors, task groups
Data Modeling dbt, SQL Kimball, Data Vault, SCD
Data Quality Great Expectations, dbt tests Validation suites, freshness

Architecture Patterns

Medallion Architecture (Recommended)

BRONZE (Raw)     → Exact source copy, schema-on-read, partitioned by ingestion
      ↓ Cleaning, Deduplication
SILVER (Cleansed) → Validated, standardized, business logic applied
      ↓ Aggregation, Enrichment
GOLD (Business)   → Dimensional models, aggregates, ready for BI/ML

Lambda vs Kappa

  • Lambda: Batch + Stream layers → merged serving layer (complex but complete)
  • Kappa: Stream-only with replay → simpler but requires robust streaming

Reference Examples

What this file has done since we first saw it

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.
