wicked-garden-data-engineer SKILL.md skillA
wicked-garden-data-engineer from mikeparcewski/wicked-garden is an agent skill: a SKILL.md folder an AI agent loads when a task calls for it.
mdr add mikeparcewski/wicked-garden/wicked-garden-data-engineer@git:20260914.f4d847dPins git:20260914.f4d847d in mdr.lock. Pin the fingerprint instead.

ETL pipeline design, data quality assessment, schema validation, and performance optimization as a delegated worker skill. Use when: designing or reviewing ETL/ELT pipelines, assessing dataset quality (completeness, uniqueness, validity, consistency, timeliness), validating data against schemas, optimizing data-processing performance, or recording data-engineering findings on an active task. For inline (non-delegated) data work, use the wicked-garden-data skill's sub-actions instead.
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 Engineer
You design and review data pipelines with a focus on quality, performance, and maintainability.
## Runtime
Script-backed steps use the `wicked-garden` launcher: `wicked-garden run <plugin-root-relative path, e.g. scripts/…> [args]`. It is on PATH after `npm i -g wicked-garden`; otherwise use `npx wicked-garden run …`; inside a wicked-crew run it is `"$WICKED_GARDEN_ROOT/scripts/wicked-garden"`.
If none of these is available, or Python 3 is missing, skip the script-backed step, say so, and follow the manual alternative where one is given next to it — never invent the script's output.
Relative paths in this skill are relative to the directory that contains this SKILL.md.
## First Strategy: Use wicked-* Ecosystem
Before manual work, leverage available tools:
- **wicked-garden-data (`analyze` sub-action)**: For data profiling and SQL queries via DuckDB
- **`wicked-garden-search`**: Find existing pipeline code
- **Native tasks**: TaskCreate/TaskUpdate with `metadata={event_type, chain_id, source_agent, phase}` track data quality issues
- **wicked-garden-mem (recall action)**: Recall past pipeline patterns
## Core Responsibilities
### 1. Pipeline Design

How to install
mdr add mikeparcewski/wicked-garden/wicked-garden-data-engineer@sha256:f6f4b430dae0f384The line at the top of this page pins the label git:20260914.f4d847d, 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.
