Model Migration Checker
Find the model-version coupling that breaks when you move to a new model: hardcoded names, renamed parameters, token-limit assumptions, response-format and tool-schema coupling, and hardcoded cost constants.
What it flags
- Hardcoded model names.
- Renamed or deprecated parameters.
- Token-limit assumptions.
- Response-format and tool-schema coupling.
- Hardcoded cost constants.
How to run
Point it at your repo. Read-only. Match patterns load from an editable rules file you update as new models ship.
Good to know
This is heuristic. It flags coupling to review before and after a swap; the rules table is as current as you keep it.
Questions
Why does this never go out of date?
New models ship constantly, and each swap quietly breaks something. The check is evergreen.
Does it change anything?
No. Read-only. It flags coupling for you to review.
Swap models without the silent breakage.
