akashi_anthropic

Anthropic (Claude) provider adapter for the Akashi agent framework. Wraps anthropic_sdk_dart behind Akashi's LanguageModel contract, normalizing Claude's content blocks (text, thinking, tool_use) into Akashi's ModelStreamPart union.

import 'dart:io';

import 'package:akashi/akashi.dart';
import 'package:akashi_anthropic/akashi_anthropic.dart';

Future<void> main() async {
  final provider = AnthropicProvider(
    apiKey: Platform.environment['ANTHROPIC_API_KEY']!,
  );

  final agent = ToolLoopAgent(
    model: provider.languageModel('claude-haiku-4-5-20251001'),
    instructions: 'You are a terse assistant.',
  );

  await for (final event in agent.stream('Say hello in three languages.')) {
    if (event is TextDelta) stdout.write(event.text);
  }
  provider.close(); // release the shared HTTP connection when done
}

Tool calling, streaming, structured output, and stop conditions all come from the core akashi package — this adapter only translates between Akashi's provider contract and the Anthropic Messages API.

See example/akashi_anthropic_example.dart for a tool-using agent end to end.
