eager-tools-core 0.3.0

Provider-agnostic core for eager tool calling — seal detector + async executor pool.

eager-tools-core

Provider-agnostic core for eager tool calling — dispatches each tool the moment its block finishes streaming, overlapping tool execution with LLM generation on the wall clock.

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

For execution plan + OSS strategy, see ROADMAP.md and NEXT.md.

Status

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

Install (once published)

pip install eager-tools-core

Public API

from eager_tools import (
    SealDetector,         # streaming chunk → SealEvent state machine
    ExecutorPool,         # async dispatcher for sealed tool calls
    ToolCall, SealEvent,  # data carriers
    Tool,                 # protocol every user tool implements
    ObservabilityHook,    # opt-in trace emitter (OTel / Langfuse / LangSmith)
    NonIdempotentToolError,
)

Adapter contract

Each provider-specific adapter (anthropic, openai, langgraph, claude-agent) consumes SealDetector + ExecutorPool and emits normalized chunks into the detector. Adapters are separate packages — see packages/eager-tools-<provider>/.
