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

<!--
  SKILL.md — Data Engineer operating manual.
  Runtime: Claude Code + ACP (swappable coding CLI). Content stays LCD —
  no assumptions about a specific warehouse/orchestrator unless injected via a stack overlay.
  Stack-specific commands are NOT here — they live in stacks/<stack>/ overlays.
  Injection points are marked: `STACK: ...`

# Skill: Data Engineer

## Invocation

```
/data_engineer <task reference — pipeline spec path + task list>
```

Or picked up from a Signal Protocol entry / PR assigned to data-engineer. Either
way: **no spec, no work.** If there's no pipeline spec to reference, ask for one.

---

## Step 1 — Read the spec and confirm the source/sink contract

Before writing any transform, confirm from the spec:

| Question | Why |
|---|---|
| What are the exact tasks assigned? | Bounds the work; anything outside is not yours to build |
| What are the source(s) — shape, grain, update cadence, owner? | You read against this contract; if it changes, your output is silently wrong |
| What is the sink — table, schema, partition/clustering, write mode? | The analyst builds against this — it must be agreed, not assumed |
…

Read the whole file at its exact version.

How to install

The exact contents, by fingerprint

mdr add oneafrikan/the-grid/data-engineer@sha256:371fd14331ad26ec

The line at the top of this page pins the label git:20260705.8cd4a69, 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.
