logicprobe-datamodel skillA
logicprobe-datamodel is agent-read markdown (skill) from amethystluna/logicprobe: Use when reviewing design documents, architecture specs, technical proposals, schema changes, data contracts, or refactoring plans that make claims about entities, fields, constraints, relationships, data invariants, migration coverage, or before/after data-model equivalence. When the document contains schema changes, data migration logic, or data-behavioral assertions ('all records must have X', 'target count equals source count', 'no orphan rows', 'migration is non-breaking'), escalate into da.
Indexed from public GitHub and served as immutable, content-addressed versions. Install it pinned to an exact SHA-256 with the mdr CLI, and every file is verified against the hash recorded here before it reaches your agent. The deterministic audit below grades the latest version, and the same file always earns the same grade.
What the file says
# Logic Probe Data
Documents are not truth — data models are. Verify every verifiable data claim before accepting or acting on a design.
## Methodology
### Phase 1: Enumerate Data Claims
Read the document fully. Extract every verifiable data-model claim:
- Entity/table/collection names and fields
- Field types, nullability, defaults, unique constraints
- Relationships / foreign keys / referential integrity
- Data invariants ("always", "never", "must", "guaranteed")
- Migration claims ("rename field", "drop column", "backfill", "non-breaking")
- Copy/migration mappings ("source.a → target.x")
### Phase 2: Verify Against the Model or Codebase
For each claim, run the relevant verification:
- **Entity/field names**: compare against actual schema, API contract, or code types
- **Constraints**: check declared `required`, `unique`, `nullable`, `min/max`, `enum`
- **Relationships**: check target entity/field exists and `onDelete` is coherent
- **Migration**: build BEFORE/AFTER DataModelV1 and check migration coverage
### Phase 2 Trigger: Escalate to Data Model Verification?
Escalate immediately if the document contains ANY of:

How to install
mdr add amethystluna/logicprobe/logicprobe-datamodel@git:20260826.bdfabbbmdr add amethystluna/logicprobe/logicprobe-datamodel@sha256:556870dabec55a71Pin to a label to follow the author's releases, or to a sha256 to freeze the exact bytes forever. Either way the resolved hash is written to mdr.lock, and mdr install reproduces it on any machine.
