Authors Great Expectations (GX Core) ExpectationSuites, builds ValidationDefinitions and Checkpoints, runs validation against tabular batches, and parses the JSON result for CI gating. Use when the user works with Great Expectations on Pandas, SQL, or Spark data.
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
# great-expectations ## Overview GX Core is the modern Python library for programmatic data validation workflows. The shape is: **DataSource → DataAsset → BatchDefinition → ExpectationSuite → ValidationDefinition → Checkpoint** ([gx-overview][1]). This skill covers authoring expectations, running them via a ValidationDefinition or Checkpoint, parsing the JSON result, and gating CI on it. [1]: https://docs.greatexpectations.io/docs/core/introduction/gx_overview ## When to use - The repo imports `great_expectations` (Python). - The user asks about `ExpectColumn*`, `ExpectationSuite`, `Checkpoint`, Data Docs, or `gx.get_context()`. - A pipeline needs row-level / column-level assertions on Pandas, SQL, or Spark data with a programmatic interface (rather than a YAML-only config like Soda). - A CI workflow needs to gate a run on a validation result and surface failures in Data Docs or Slack. ## Authoring expectations The four key objects to compose ([gx-overview][1]): 1. **DataSource** - represents a connection to a data store (Pandas / SQL / Spark / files). 2. **DataAsset** - a collection of records inside a DataSource (e.g. a …

How to install
mdr add testland/qa/great-expectations@sha256:ebc5ef6384041a65The line at the top of this page pins the label git:20260706.d9cec5f, 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.
