ChainWeaver v0.0.1 — Initial Release

Deterministic orchestration layer for MCP-based agents. No LLM calls between steps — all data passing is structured and schema-validated via Pydantic.

Core Features

  • Tool — schema-validated callable wrapping Pydantic input/output models
  • Flow / FlowStep — ordered, deterministic step sequences with input mapping (context keys + literal constants)
  • FlowRegistry — in-memory registry with register, get, list, and intent-based matching
  • FlowExecutor — sequential runner with full error recording in ExecutionResult
  • Typed exceptions — ToolNotFoundError, FlowNotFoundError, FlowAlreadyExistsError, SchemaValidationError, InputMappingError, FlowExecutionError
  • Logging — library-safe NullHandler pattern; step-level log_step_start / log_step_end / log_step_error helpers; DEBUG-level context key collision warnings
  • PEP 561 — py.typed marker included

Test Suite

32 tests covering: successful execution, error wrapping, schema validation, input mapping (including empty passthrough), empty flows, Tool.run() isolation, and missing tool/flow handling.

Requirements

  • Python >= 3.10
  • pydantic >= 2.0
