Overview
Concrete tool for performing comprehensive consistency checks across the entire Transformers repository, validating model registration, test coverage, documentation, and auto-class mappings.
Description
The check_repo.py utility (1333 lines) is the most comprehensive repository integrity checker. It uses AST parsing, introspection, and file-system scanning to verify: (1) all models are in their module's __init__, (2) all models appear in the main __init__, (3) all models have corresponding test files, (4) all public objects are documented, (5) all models are registered in at least one auto class, (6) auto mappings have no typos and are importable, and (7) the deprecated model list is current. It maintains extensive allow-lists for known exceptions (private models, models not in auto mappings, etc.). Has no auto-fix mode.
Usage
Run via make check-repo as the primary repository consistency gate. Ensures new models are fully integrated across all library layers (init, auto classes, tests, docs).
