[seefs001]

#1633

Summary by CodeRabbit

• New Features
  • Added support for a URL Context tool in Gemini, allowing requests to include URLs as context to improve response relevance.
  • Automatically integrates with existing tool handling; no action required if unused.
  • Backwards-compatible: behavior remains unchanged when no URL context is provided.

Walkthrough

Adds URLContext support to Gemini tools: a new URLContext field on GeminiChatTool and relay logic to parse urlContext from requests and append the corresponding tool to the Gemini tools list alongside existing GoogleSearch and CodeExecution handling.

Changes

Cohort / File(s)	Summary
Gemini DTOs dto/gemini.go	Added public field URLContext any \json:"urlContext,omitempty"`toGeminiChatTool` to allow optional URL context serialization.
Gemini Relay Tool Handling relay/channel/gemini/relay-gemini.go	Extended tool parsing to recognize urlContext in textRequest.Tools and append a GeminiChatTool with URLContext set, mirroring existing GoogleSearch and CodeExecution integration paths.

Poem

I nibbled the docs, ears perked with delight,
A new URLContext hops into sight—
Tools in a basket, three carrots abreast,
Gemini’s relay now handles the rest.
Tap-tap my paws: ship it, don’t delay—
More links to chew on today! 🥕
