Wire ETL, ingestion, cron, and queue jobs with idempotency, atomic writes, data contracts, and dead-letters. Use for "build a pipeline", "sync X into Y", "cron double-counts", "dedupe", "backfill", or "the numbers are wrong after a retry".
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 Pipeline Correctness **Degree of freedom: MIXED.** Layering and window design `[HIGH freedom]`; idempotency, atomic writes, overlap lock, and the DoD `[LOW freedom — run exactly]`. ## How to reason 1. **Observe** — job, retry path, write targets, schedule 2. **Interpret** — at-least-once vs atomic vs contract vs overlap 3. **Classify** — upsert / window-recompute / quarantine / lock / watermark 4. **Severity** — retry double-count outranks a missing metric ## Worked example > **Observe:** nightly `refresh_order_stats` does `count = count + 1`; cron overlapped twice; dashboard totals jumped. > **Interpret:** at-least-once delivery + non-idempotent delta. > **Classify:** recompute-and-replace the day window; `pg_try_advisory_lock`; persist a watermark. > **Verify:** re-run the same window → identical rows; overlap skipped; `pipeline_runs` recorded. ## Self-critique before reporting - **Idempotent** — same-window re-run proven identical, not assumed - **Atomic** — mid-fail leaves no half-written batch - **Locked** — the scheduled job has an overlap guard - **Right owner** — schema/constraints → `audit-db-schema`; post-hoc corruption hunt → `plan-data-integrity` …

How to install
mdr add kensaurus/cursor-kenji/data-pipeline@sha256:2e627ca1074cf9b0The line at the top of this page pins the label git:20260923.68c095e, 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.
