Audit Python dependency declarations for unused, missing, and transitive imports before release

Use Deptry when an agent needs to verify that a Python project's declared dependencies still match the imports the code actually uses. The agent scans the codebase, flags unused direct dependencies, missing declarations, and transitive imports that only work by accident, then turns the findings into cleanup commits or release blockers.

Prerequisites

Python plus Deptry configured against the target repository

Installation

Use the upstream install or setup path that matches your environment:

• uv add --dev deptry
• pip install deptry

Requirements and caveats from upstream:

• 
• deptry is a command line tool to check for issues with dependencies in a Python project, such as unused or missing
• using Poetry, pip, PDM, uv,

Basic usage or getting-started notes:

• To add deptry to your project, run one of the following commands:

• shell

• poetry add --dev deptry
