GitLab Duo CLI (experimental)

GitLab Duo for your command line. An AI-powered CLI tool that brings GitLab Duo Chat (Agentic) to your terminal.

The GitLab Duo CLI can help you:

• Understand your codebase structure, cross-file functionality, and individual code snippets.
• Build, modify, refactor, and modernize code.
• Troubleshoot errors and fix code issues.
• Automate CI/CD configuration, troubleshoot pipeline errors, and optimize pipelines.
• Perform multi-step development tasks autonomously.

This tool is experimental and some features might not work as expected.
