akashi_anthropic 0.3.0

Anthropic (Claude) provider adapter for the Akashi agent framework: wraps anthropic_sdk_dart behind Akashi's LanguageModel contract, normalizing text/thinking/tool_use blocks.

example/akashi_anthropic_example.dart

// A tiny end-to-end example of the Anthropic adapter: a streaming agent that
// calls a typed tool. Run with `dart run example/akashi_anthropic_example.dart`
// (needs ANTHROPIC_API_KEY).
