Description

I have nearly identical config files set up for claude 3.7 and 4.0 but 4.0 gives a vscode popup saying 'File exceeds context lenght'. 3.7 works fine. This happens on two computers (both macOS and vscode).

To reproduce

1. save config.yaml:

- name: Claude 4.0 Sonnet no context
  provider: anthropic
  model: claude-sonnet-4-20250514
  apiKey: same_key1
- name: Claude 4.0 Sonnet with context
  provider: anthropic
  model: claude-sonnet-4-20250514
  apiKey: same_key1
  defaultCompletionOptions:
   contextLength: 100000
- name: Claude 3.7 Sonnet
  provider: anthropic
  model: claude-3-7-sonnet-latest
  apiKey: same_key1

2. Select Claude 4.0 Sonnet no context or Claude 4.0 Sonnet with context in 'Select Model' dropdown.
3. Add any file (as small as bytes)
4. Get popup

Log output

No console logs are generated by this action.
