+# CLAUDE.md
+
+This file provides guidance to Claude Code (claude.ai/code) when working with code in this repository.
+
+## Project Overview
+
+This is a Python implementation of the Pipeline pattern, distributed as `thecodecrate-pipeline`. The package allows composing sequential stages into reusable, immutable pipelines for processing data. It's inspired by the PHP League Pipeline package.
+
+## Development Commands
+
+### Environment Setup
+```bash
+# The project uses uv for dependency management
+# Dependencies are managed in pyproject.toml under [dependency-groups]
+uv sync
+```
+
+### Testing
+```bash
+# Run all tests
+pytest
+
+# Run tests with coverage
+pytest --cov
+
+# Run a specific test file
+pytest tests/test_pipeline.py
+
+# Run a specific test function
+pytest tests/test_pipeline.py::test_function_name
+```
+
+### Code Quality
+```bash
+# Format code with ruff
+ruff format .
+
+# Lint with ruff
+ruff check .
+
+# Fix auto-fixable linting issues
+ruff check --fix .
+
+# Format with black (line length: 79)
+black .
+
+# Type checking is configured with strict mode in pyrightconfig.json
+# Type check manually: pyright (if installed)
+```
+
+### Documentation
+```bash
+# Build documentation locally
+mkdocs serve
+
+# Documentation is built with mkdocs-material and auto-generates API docs
+# from docstrings using mkdocstrings-python
+```
+
+### Version Management
+```bash
+# Bump version (uses bumpver)
+bumpver update --patch   # 1.26.0 -> 1.26.1
+bumpver update --minor   # 1.26.0 -> 1.27.0
+bumpver update --major   # 1.26.0 -> 2.0.0
+
+# Note: bumpver automatically commits and tags, but does NOT push
+```
+
+## Architecture
+
+### Core Concepts
+
+The codebase implements a pipeline pattern with three main abstractions:
+
+1. **Stage**: A callable unit that transforms input to output (`StageInterface[T_in, T_out]`)
+2. **Pipeline**: An immutable chain of stages (`PipelineInterface[T_in, T_out]`)
+3. **Processor**: Controls how stages are executed (`ProcessorInterface[T_in, T_out]`)
+
+### Directory Structure

+```
+
+### Key Design Patterns
+
+**Immutability**: Pipelines use copy-on-write semantics. The `pipe()` method creates a new pipeline instance with the added stage, preserving the original pipeline.
+
+**Traits System**: The codebase uses a trait-like pattern with mixins:
+- `Clonable`: Provides shallow cloning capability
+- `ActAsFactory`: Enables objects to act as factories for creating instances
+
+**Interface Segregation**: Each core concept has an interface (`*Interface`) and implementation, enabling custom implementations while maintaining type safety.
+
+**Async-First**: All processing is async (`async def process(...)`). The processor handles both sync and async callables transparently using `inspect.isawaitable()`.
+
+### Type System
+
+The codebase uses generic type variables for type safety:
+- `T_in`: Input type to a stage or pipeline
+- `T_out`: Output type from a stage or pipeline (defaults to `T_in`)
+
+Stages can transform types:
+```python
+Pipeline[int, str]  # Takes int, returns str
+StageInterface[int, int]  # Takes int, returns int
+```
+
+### Processing Flow
+
+1. A Pipeline is created with stages (either via `.pipe()` or declaratively)
+2. When `.process(payload)` is called, the pipeline:
+   - Instantiates stages if needed (converts classes to instances)
+   - Delegates to the processor's `.process()` method
+   - The processor iterates through stages, passing output to next stage
+3. Processors can customize execution (e.g., ChainedProcessor for error handling)
+
+### Stream Processing
+
+Pipelines support processing `AsyncIterator` streams, allowing real-time data transformation where each stage can yield results consumed immediately by the next stage.
+
+### PipelineFactory
+
+Because pipelines are immutable, `PipelineFactory` provides mutable stage collection during composition. It builds the final immutable pipeline via `.build()`.
+
+## Testing Notes
+
+- Test files use stub classes in `tests/stubs/` for consistent test fixtures
+- Tests are async-aware (configured via `pytest.ini` with `pytest-asyncio`)
+- Mock stages implement `StageInterface` for type safety
+
+## Python Version
+
+Requires Python 3.13+ (specified in pyproject.toml).
+
+## Package Distribution
+
+Built with `hatchling`. The wheel includes both `thecodecrate_pipeline` (public API) and `_api` packages (internal). The public package re-exports symbols from `_lib`.

-## Architecture
-
-All code is located in the `src/_api` directory and follows the Static-Plugin Design (SPD) pattern. This architectural approach ensures:
-
-- Clear separation of concerns through static plugins
-- Full static analysis capabilities
-- Predictable code execution paths
-- Zero runtime overhead
-
-The project utilizes class composition rather than dynamic plugins, making the codebase easier to maintain and debug while preserving extensibility.
