Problem
The existing experimental_repairToolCall handler normalizes case and separators (e.g. todo_write → todowrite), but many models consistently call tools by common synonyms that don't match any tool name even after normalization — search instead of grep, find instead of glob, cat instead of read, etc.
When this happens, the tool call falls through to the "invalid" fallback, and the model retries the same synonym in an infinite loop:
Expected behavior
Common tool synonyms should be resolved automatically by the repair handler, similar to how case/separator normalization already works. Users should also be able to define custom alias mappings via config for their specific setups.
