Informations about the package laravel-model-analyzer
Laravel Model Analyzer
A Laravel package that scans your Eloquent models and validates their relationships against your actual database schema. It detects missing inverse relationships, circular dependencies, missing foreign key columns, missing indexes, and more — then reports a health score for your model layer.

What It Detects
| Issue | Severity | Description |
|---|---|---|
| Missing inverse relationship | Warning | e.g. User hasMany Post exists but Post belongsTo User is missing |
| Circular dependency | Error | Two models reference each other in a way that creates a loop |
| Missing foreign key column | Error | A relationship references a column that does not exist in the database |
| Missing index on foreign key | Warning | A foreign key column has no index, which can hurt query performance |
Health Score
The model-analyzer:analyze and model-analyzer:health commands calculate a 0–100 health score based on the number and severity of issues found relative to the total number of relationships. A score of 100 means no issues were detected.
CI Integration
Run the analyzer in strict mode to fail your pipeline when any issue is found:
Or allow warnings but fail only on errors (the default):
