📄 Description

Add middleware to support the Anthropic Messages API format at /v1/messages.
This enables tools like Claude Code to work with Ollama models through the Anthropic API interface.

Features:

  • Request/response transformation between Anthropic and internal formats
  • Streaming support with SSE events (message_start, content_block_delta, etc.)
  • Tool calling support (tool_use and tool_result content blocks)
  • Thinking/extended thinking block support
  • Image content block support (base64)
  • System prompt handling
  • Multi-turn conversation support
  • Proper stop_reason mapping (end_turn, max_tokens, tool_use)
  • Error responses in Anthropic format

New files:

  • anthropic/anthropic.go: Types and transformation functions
  • middleware/anthropic.go: Request/response middleware
