## What it is
Import Linter is a command-line tool that checks and enforces constraints on imports between Python modules, helping teams maintain clean architectural boundaries. It also includes a browser-based UI for exploring a package's architecture.

## Use cases
- enforce layered architecture rules in a python codebase
- prevent circular imports between modules
- lint python package dependencies between modules
- visualize the import graph of a python package
- forbid imports from higher layers to lower layers
- check that contracts between packages are respected in CI

## When to choose
- you want to codify and enforce architectural rules for a Python codebase
- you need CI checks that fail when forbidden imports are introduced
- you want to explore or document module dependency structure

## When to avoid
- you need general-purpose style linting (use ruff or flake8)
- your project is not written in Python
- you need runtime dependency analysis rather than static import checking

## Facets
- artifact type: cli-tool
- maturity: active
- function: linter, static-site-generator
- domain: developer-tools
- platform: cli, python, cross-platform
- tags: import-linting, architecture-constraints, dependency-rules, code-quality, architecture, python
