Clean, profile, validate, reshape, and document messy tabular, text, JSON, and relational data through an evidence-first, reproducible workflow. Use when preparing data for analysis, reporting, modeling, ingestion, migration, or matching, including AI-suggested repair, entity-match review, score calibration limits, and reversible repair ledgers. Do not use for statistical modeling, dashboard design, or operating a named data platform; route those tasks to data-scientist, data-engineering, or…
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 cleaning Treat cleaning as a controlled transformation of an observed dataset, not cosmetic editing. Preserve raw input, state the target use and grain, make every lossy decision explicit, and prove that the cleaned output satisfies a contract. When a model proposes data transformations, load [the AI boundary workflow](references/ai-repair-review.md) and use [the companion record](templates/ai-repair-ledger.csv). ## Route by task | Need | Read next | |---|---| | End-to-end method, scope, and stopping rules | `references/methodology.md` | | Choose a library or platform | `references/tool-selection.md` | | Missingness, duplicates, types, ranges, categories, dates, joins | `references/operations.md` | | Text, identifiers, Unicode, and entity resolution | `references/text-and-entity.md` | | Schemas, contracts, validation, drift, scale | `references/validation-and-scale.md` | | CLI, OpenRefine, monitoring, and interactive remediation | `references/cli-and-interactive-tools.md` | | Source claims and version-sensitive caveats | `references/sources.md` | …

How to install
mdr add magnus919/agent-skills/data-cleaning@sha256:2782fc15db1fa68aThe line at the top of this page pins the label git:20260914.9917fb4, 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.
