Use at the ingestion edge, to enforce field types, nullability and value bounds against a declared contract and catch silent vendor schema drift such as a renamed field or a price arriving as a string.
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
## When to Use Use this skill at the ingestion edges of quantitative market data pipelines, feature stores, and execution algorithms. Market data vendors frequently introduce silent schema changes (renaming `ask_sz` to `ask_volume`, sending string prices instead of floats, or spiking null values during market volatility). This module validates incoming records against explicit `SchemaContract` definitions, quarantining corrupt payloads to a Dead Letter Queue (DLQ) before they corrupt feature stores or trading models. ## When NOT to Use - **As a statistical or distributional data-quality monitor.** This engine answers "does this record match the declared structure?", not "does this value look wrong relative to recent history?". Stale-but-well-formed quotes, frozen prices, latency degradation, and duplicate ticks all pass a schema contract cleanly — use `data-quality-monitoring-dashboard` for those dimensions. - **As a cross-vendor reconciler.** Validating vendor A and vendor B against the same contract does not establish that they agree; see `multi-source-price-reconciliation-tie-breaking` and `cross-vendor-timestamp-precision-reconciliation`. …

How to install
mdr add himanshuj16/algo-trading-skills/data-pipeline-schema-contract-testing@sha256:b683195428bb86d2The line at the top of this page pins the label v1.0.0, 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.
