What does CodeQL CLI provide?

• A. A standalone tool to analyze code and generate a CodeQL database
• B. A cloud-based hosting service
• C. A textual code linter
• D. A diagnostic tool for runtime errors

Answer: (A)

CodeQL CLI is a standalone command-line tool that analyzes code and builds a CodeQL database. It takes your source code and, through static analysis, creates a semantic snapshot of the project (including code structure, control flow, and data flow) stored in a CodeQL database. Once you have that database, you can run CodeQL queries to detect security issues, quality problems, or custom patterns across the codebase. This workflow is designed for local use or integration into CI pipelines, and it isn’t a cloud hosting service by itself. It isn’t a textual linter, which would focus on style or simple patterns, nor a runtime diagnostic tool that observes a live application. The strength of the CLI lies in enabling deep, language-aware analysis through building the database and then querying it.
