google-gemini/gemini-cli
This system is a comprehensive command-line interface and agent framework designed for AI-assisted software development. It provides a modular architecture for managing extensions, skills, and MCP servers, while offering a rich interactive UI for chat, code review, and browser automation. The core engine handles model routing, policy enforcement, and secure sandboxing across Linux, macOS, and Windows, enabling safe execution of tools and subagents. Additionally, it includes infrastructure for automated issue triage, performance monitoring, and SDK integration for embedding agent capabilities into other applications.

About this page
- The description of this project is derived from its own commit history, not from its README.
- The score is its highest published measurement, taken on 19 July 2026 at a pinned commit. It is not a live figure and does not change until the project is measured again.
- Measured at commit acae7124bd — the exact code this score is about.
- Scored under rubric rubric-2026.08.17. Score the same commit under that rubric and you get the same number.
