# Inputs Safety allows you to scan your Python dependencies in a few different ways: ### Scanning your current environment Safety can scan your current environment for all packages that are currently installed. This type of scan will ensure that all downstream (recursive) package installations are audited and checked for security vulnerabilities. `safety check --key ` ### Scanning a requirements.txt file `safety check -r --key ` ### Piping requirements into Safety You can pipe your requirements.txt content directly into Safety via the `--stdin` argument. For example: `cat requirements.txt | safety check --key --stdin` --- # Agent Instructions: Querying This Documentation If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.
