ChainWeaver v0.0.1

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

What's Changed

• feat: ChainWeaver v0.1.0 — deterministic MCP tool-chain orchestration by @Copilot in #1

New Contributors

• @Copilot made their first contribution in #1
