eager-tools-anthropic

Anthropic adapter for eager tool calling — wraps anthropic.AsyncMessageStream and dispatches each tool the instant its block seals, overlapping tool execution with ongoing LLM generation.

For the mechanism and runtime contract, see the top-level METHOD.md.

Status

Alpha / scaffold. Public API shape is locked; implementation bodies arrive in Move 3 (CloudThinker port). See NEXT.md.

Install (once published)

pip install eager-tools-anthropic

Usage

import anthropic
from eager_tools_anthropic import AnthropicEagerStream

client = anthropic.AsyncAnthropic()

async with client.messages.stream(
    model="claude-opus-4-6",
    tools=[...],
    messages=[...],
) as source:
    runner = AnthropicEagerStream(source, tools=my_tools)

    async for event in runner.events():
        print(event.kind, event.tool_call)

    async for call, result in runner.results():
        print(call.name, "→", result)
