Fix handling of nil MediaType in image content processing

This PR addresses a bug where the code was dereferencing potentially nil MediaType pointers in the Anthropic, Bedrock, and Cohere providers. The fix adds null checks before accessing the MediaType field, preventing potential nil pointer dereference panics.

Additionally, the PR removes the unused coalesceString helper function and updates the OpenAI provider to directly use the Content field without unnecessary coalescing.

Summary by CodeRabbit

  • Bug Fixes
    • Improved handling of optional image media types to prevent potential errors when processing image content from various providers.
  • Refactor
    • Updated the structure of assistant message content in requests sent to the OpenAI API.
  • Chores
    • Removed an unused utility function related to string handling.

Walkthrough

This update refactors how image content structs are initialized across several provider implementations, ensuring that the MediaType field is only set when non-nil. Additionally, it removes the coalesceString utility function and changes how the assistant message content is assigned in the OpenAI provider.

Changes

File(s) Change Summary
core/providers/anthropic.go
core/providers/bedrock.go
core/providers/cohere.go
Refactored struct initialization to set MediaType only if non-nil, preventing potential nil pointer dereference.
core/providers/openai.go Changed assistant message content assignment to use the full msg.Content instead of extracting a string.
core/providers/utils.go Removed the coalesceString utility function.

Poem

In fields of code where structs reside,
A rabbit hops with careful pride—
"Set fields with care, nils beware!"
No pointer traps or bugs to snare.
With every hop, the code grows bright,
Safe and sound, it runs just right! 🐇✨

Learning: In core/providers/anthropic.go, the content field in formattedMessages is always of type []interface{} because it's explicitly constructed that way upstream in the prepareAnthropicChatRequest function. Defensive type casting for multiple types is not needed since the type is guaranteed by the construction logic.

Conditional assignment prevents a panic and keeps downstream logic intact.

338-343: Nil-safe media-type handling LGTM.

Matches Bedrock/Cohere fixes and removes panic risk.
