…I rejection Anthropic's API returns a `caller` field in `tool_use` response blocks but rejects this field when sent back in subsequent requests. This filters `tool_use` blocks to only include accepted fields: `type`, `id`, `name`, and `input`. 🤖 Generated with [Claude Code](https://claude.com/claude-code) Co-Authored-By: Claude <noreply@anthropic.com>

Summary by cubic
Strip unsupported fields from tool_use blocks before sending to Anthropic to prevent validation errors and multi-step agent failures. Only type, id, name, and input are kept; caller is removed.
