## Overview

#### Purpose
This is a Python package centered on `dev_tools.project_context`, likely intended to expose project-context functionality for developer tooling. The repository is small and organized as a distributable source package rather than an application service.

#### Entry Points and Packaging
- Package root: `src/dev_tools/__init__.py`
- Feature package: `src/dev_tools/project_context/__init__.py`
- Command-line boundary: `src/dev_tools/project_context/cli.py`
- Distribution, dependencies, and potential console-script registration are defined in `pyproject.toml`.

The CLI module is the primary executable-facing entry point; consumers may also import the package API directly.

#### Core Component: Project Context Feature
`src/dev_tools/project_context/` is the architecture-defining subsystem:
- `src/dev_tools/project_context/cli.py` contains command-line orchestration.
- `src/dev_tools/project_context/__init__.py` establishes the import/package boundary.
- `src/dev_tools/project_context/README.md` provides feature-local documentation.

The feature is isolated under its own namespace, allowing it to evolve independently from other future `dev_tools` capabilities.

#### Primary Control Flow
The expected control path is:
1. A user or automation invokes the project-context CLI.
2. `src/dev_tools/project_context/cli.py` parses and handles the invocation.
3. The CLI calls project-context package behavior and emits results through the command-line interface.
4. Python consumers can bypass the CLI and access exported behavior through `src/dev_tools/project_context/__init__.py`.

The main boundary is between shell-facing argument/output handling in `cli.py` and reusable package-level functionality.

#### Validation Boundary
Behavior is validated through:
- `tests/test_project_context.py`

This test module is the primary executable specification for project-context behavior and should be updated alongside CLI or package-contract changes.

#### Runtime, Delivery, and Infrastructure
- Runtime: Python, with source-layout packaging under `src/`.
- Build/package configuration: `pyproject.toml`.
- CI validates tests and binary builds through `.github/workflows/tests.yml` and `.github/workflows/build-binaries.yml`.
- No database, web runtime, cloud infrastructure, or external service integration is evidenced by the provided tree.

#### Change Planning Implications
Changes to command behavior should trace across `src/dev_tools/project_context/cli.py`, the package exports in `src/dev_tools/project_context/__init__.py`, and `tests/test_project_context.py`. Packaging or executable-distribution changes additionally affect `pyproject.toml` and the binary build workflow.
