data-pipelines from darknecrocities/skillbuilder is an agent skill: a SKILL.md folder an AI agent loads when a task calls for it.
mdr add darknecrocities/skillbuilder/data-pipelines@git:20261029.b0bed3fPins git:20261029.b0bed3f in mdr.lock. Pin the fingerprint instead.

Data pipeline engineering, streaming ETL with backpressure, Apache Arrow memory structures, DuckDB in-process analytics, schema validation, and dead-letter queues (DLQ).
Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file the same grade.
What the file says
# Data Pipelines, Streaming Ingest & Embedded Analytics (`/data-pipelines`) > **Philosophy**: *Unbounded in-memory aggregation is an architectural failure. Stream large datasets with backpressure. Validate schemas at every record boundary. Enforce idempotency on batch runs. Route poisoned records to Dead-Letter Queues (DLQ) without crashing the pipeline.* This skill establishes defensive engineering standards for data pipelines, batch ETL, and embedded analytical workloads using **DuckDB**, **Apache Arrow**, **Polars**, and **Pandas**. --- ## 1. Quick Navigation & Progressive Disclosure | Resource Type | Document | Description | | :--- | :--- | :--- | | **Reference** | [references/streaming-etl-and-arrow.md](references/streaming-etl-and-arrow.md) | Columnar memory, zero-copy RecordBatches, bounded queue backpressure. | | **Reference** | [references/duckdb-and-dlq-patterns.md](references/duckdb-and-dlq-patterns.md) | Vectorized in-process analytics, Parquet queries, DLQ quarantine schemas. | | **Utility** | [scripts/verify_pipeline_integrity.py](scripts/verify_pipeline_integrity.py) | Scans pipeline code for unbounded reads, missing DLQ handling, and unindexed joins. | --- …

How to install
mdr add darknecrocities/skillbuilder/data-pipelines@sha256:a8d6fee8736aef50The line at the top of this page pins the label git:20261029.b0bed3f, which is what most people want. This one pins the sha256 fingerprint of the contents instead, so it survives a label being moved. Either way the exact version is written to mdr.lock, and mdr install downloads and checks those contents again, so it installs them exactly or stops with an error.
