Use when a change touches dbt semantic models, metrics, saved queries, or other semantic-layer YAML -- especially when an existing metric's expression, aggregation, filters, or dimensions are modified.
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
## Purpose Changes to the semantic layer directly impact dashboards and business reporting. A silent drift in a metric definition destroys trust. Review every semantic-layer change for mathematical soundness and backwards compatibility before approval. ## When to Use - A PR modifies metric or semantic model YAML - A metric's `expr`, aggregation, or filters are changing - New dimensions or entities are being added to an existing semantic model ## Inputs - The semantic-layer diff (semantic models, metrics, saved queries) - The underlying model's grain and entity keys ## Workflow 1. **Enumerate what changed:** ```bash git diff origin/main...HEAD -- '*.yml' '*.yaml' dbt ls --resource-type metric dbt ls --resource-type semantic_model ``` 2. **Identify the change type:** - **Addition** — safe (adding a new metric or dimension). - **Deprecation** — requires communication (removing a metric). - **Modification** — high risk (changing the SQL expression, aggregation, or filters of an existing metric). 3. **Evaluate mathematical soundness:** - Are we averaging an average? - Are we summing a distinct count? …

How to install
mdr add yeaight7/agent-powerups/semantic-layer-change-review@sha256:528c27fd2435a2fbThe line at the top of this page pins the label git:20260605.f27d14b, 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.
