data-model-verification SKILL.md skillA
data-model-verification from lazyisefficient/agentic-os is an agent skill: a SKILL.md folder an AI agent loads when a task calls for it.
mdr add lazyisefficient/agentic-os/data-model-verification@git:20260716.7c29779Pins git:20260716.7c29779 in mdr.lock. Pin the fingerprint instead.

Adversarially verifies DATA_MODEL.md property rows against cited Source files. Use after data-model-documenter when DATA_MODEL.md changed — inventories each property in added/changed catalog sections and classifies VERIFIED / REFUTED / UNVERIFIABLE. Triggers on "verify DATA_MODEL", "check catalog against source", "data model verification".
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 Model Verification
Gate node **`G-data-verify`** ([gate-dag.md](../../references/gate-dag.md)). Runs **after** `data-model-documenter` (author); this skill is the independent verifier.
## Scope
Verify only **added or changed** `###` catalog sections in `DATA_MODEL.md` (from diff or explicit section list). For each section:
1. Read **Source** path(s) from the section metadata table
2. Inventory every row in the section **Properties** table (assign IDs `P1`, `P2`, …)
3. Verify each property **as named** in the catalog — not a paraphrase
Skip: unchanged sections, changelog-only edits, template example sections marked for removal.
## Tier 0 extractors (preferred when Source matches)
When **Source** is a JSON Schema file (`.json` with `"properties"` or `$schema`), run deterministic extractors **before** manual quote verification:
```sh
PROJ="${CLAUDE_PROJECT_DIR:-.}"
EDM="$PROJ/scripts/extract-data-model"
bash "$EDM/json-schema.sh" path/to/schema.json > /tmp/shape.json
bash "$EDM/verify-data-model-section.sh" \
--extracted /tmp/shape.json \
--catalog "$PROJ/DATA_MODEL.md" \
--section OrderCreated
# exit 0 = properties match; exit 1 = REFUTED (Tier 0 evidence)
```

How to install
mdr add lazyisefficient/agentic-os/data-model-verification@sha256:034fd273b9f04767The line at the top of this page pins the label git:20260716.7c29779, 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.
