Nexus Chat v1.1.1 — Anthropic Tool Support
What's New
Anthropic Tool Use
Web search and Skills are now fully functional when using the Anthropic API provider. Previously, these agentic features were only available with LiteLLM and OpenAI.
Under the hood, the main process now handles the full translation between OpenAI's tool format (used by the renderer) and Anthropic's native format:
- Tool definitions are converted from function.parameters → input_schema
- Assistant messages with tool calls are converted to Anthropic tool_use content blocks
- Tool results are grouped into Anthropic tool_result user messages
- Anthropic's tool_use stop reason is normalized back to the OpenAI shape so the agentic loop works identically across all providers
No configuration changes are needed — web search and Skills work as-is when Anthropic is selected as your provider.
