Generate a data dictionary documenting entities, fields, and business rules. Use when the user says "data dictionary", "document the data model", "what fields are in this table", "data definitions", "field descriptions", "CRUD matrix", "entity relationship", "data catalogue", "what data does this system store" - even if they don't explicitly say "data dictionary".
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
## Reference Files - `references/data-dictionary-template.md` - Template table with all standard columns (field name, description, data type, format, valid values, source, owner, business rules, nullable, example). Read this in Step 3 when documenting individual entities. ## Overview Based on the **BABOK Guide v3 (IIBA)** - Data Dictionary technique, which defines a data dictionary as a structured repository of data element definitions that eliminates ambiguity about what data means, where it comes from, and who owns it. Also draws on **Business Analysis Techniques** by James Cadle for Entity-Relationship Diagrams, CRUD Matrix, and Data Dictionary best practices. The key insight: a data dictionary is not a database schema dump. It is a business-facing document that defines what each data element means in business terms, who is the authoritative source, and what rules govern its values. ## Workflow ### Step 1: Identify data sources and scope ``` SYSTEM(S): [which systems are in scope] PURPOSE: [why this data dictionary is being created - new build, migration, integration, audit] AUDIENCE: [who will use this - developers, testers, business users, auditors] …

How to install
mdr add qa-aman/claude-skills/data-dictionary@sha256:1cdb8df9bc55e317The line at the top of this page pins the label git:20260323.771ca1c, 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.
