Users can save settings without field validation. The save appears successful even when it does not persist. There is no present format validation for each settings form field.

Example: users can "successfully" save a single special character as an api key.

Steps to Reproduce

  1. Settings -> LLM
  2. Save invalid setting
  3. Save appears successful

Actual Behavior

  1. Settings -> LLM
  2. Save "-" as api key
  3. Save appears successful

Expected Behavior

  1. Settings -> LLM
  2. Enter "." as base url
  3. Render validation error "Url must be X chars"
  4. User must enter correct url format
  5. User is able to save

Contributor guide

Research direction
Add input validation for settings form fields. Identify where the settings are saved and enforce format checks (e.g., URL format for base URL, length for API key).
