+
+## Description
+
+We want to expand the CLI tool's capabilities to scan project dependencies for known vulnerabilities.
+
+## Goal
+
+Add a new CLI command `securelens audit <path>` that scans package descriptors (such as `requirements.txt` or `package.json`) and runs checks against the Open Source Vulnerability (OSV.dev) database API.
+
+## Requirements
+
+1. Parse common package files to extract dependency names and versions.
+2. Submit query requests to the OSV API (`https://api.osv.dev/v1/query`).
+3. Format the results in a clear CLI table using `rich` showing packages, affected versions, and severity.
