logicprobe-datamodel SKILL.md skillA
logicprobe-datamodel from amethystluna/logicprobe is an agent skill: a SKILL.md folder an AI agent loads when a task calls for it.
mdr add amethystluna/logicprobe/logicprobe-datamodel@git:20261018.c165e70Pins git:20261018.c165e70 in mdr.lock. Pin the fingerprint instead.

Use when reviewing design docs, specs, plans or migrations claiming entities, fields, constraints, relationships, data invariants, or before/after data-model equivalence: schema changes, migration logic, or data guarantees ('all records must have X', 'no orphan rows', 'ids unique') want executable data-model verification (migration coverage, copy consistency, rollback symmetry, DD1-DD4 regression). State machines and protocols: logicprobe; diagrams: logicprobe-uml.
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
# Logic Probe Data
> **Successor: `dsh-model-everything`.** Its counterpart skill is `model-everything-datamodel`, over `model_datamodel_verify`. Load that one when both plugins are installed; this skill stays accurate for `logicprobe_datamodel_verify`.
An unverified data model fails later. Model the schema and the migration, run them, and it becomes clear. Check every data claim before you act on it.
## 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`

How to install
mdr add amethystluna/logicprobe/logicprobe-datamodel@sha256:fa95e247b840e727The line at the top of this page pins the label git:20261018.c165e70, 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.
