[FEATURE]: Auto-trim tool names in experimental_repairToolCall #24924
Description
Feature hasn't been suggested before.
- I have verified this feature I'm about to request hasn't been suggested before.
Describe the enhancement you want to request
Problem:
Some models (e.g., kimi-k2.5) occasionally generate tool calls with leading/trailing whitespace in the tool name (e.g., ' bash' instead of 'bash'). This causes the SDK to throw "Model tried to call unavailable tool ' bash'" errors, even though the tool exists.
Current Behavior:
The experimental_repairToolCall callback only handles case mismatches (e.g., 'Bash' → 'bash'), but not whitespace issues.
Proposed Solution:
Automatically trim whitespace from tool names before validation, or provide a built-in repair mechanism similar to case-insensitive matching.

This issue might be a duplicate of an existing issue. Please check:
' bash'instead of'bash'), causing tool call failures. That issue also references the same model and identical symptom.If your feature request adds something beyond what's already tracked in #4279, please clarify the distinction there or here so maintainers can decide whether to merge or keep them separate.
