data-engineer

data-engineer is a skill for Claude Code, Codex from Adelie-Squad/solosquad. It costs 37 tokens per session (539 once invoked), scanned A, original, MIT.

A data engineering skill for collecting, storing, transforming, and checking data. It covers data from external websites or APIs, data pipelines, and warehouses such as BigQuery; a warehouse is a system built for storing data for later use.

In plain words
What is it for?
Use it to define data schemas, ingest and store raw data, build ETL or ELT pipelines, design warehouses, monitor data quality, and plan safe backfills or replays.
Why use it?
It helps prevent unreliable data caused by missing values, duplicates, broken schemas, or failed reprocessing. It also keeps collection and storage work together so data does not get lost between teams.

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-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 3d 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.

담당 범위 (구 data-collector)

  • 외부 데이터 수집 (scrape / API ingestion)
  • 데이터 schema 정의
  • raw data 저장

담당 범위 (구 data-engineer)

  • ETL / ELT 파이프라인
  • warehouse 설계 (dbt, BigQuery, etc.)
  • 데이터 quality 모니터링
  • backfill / replay 처리

담당하지 않는 것

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.
