Best Agentic CLI Coding Tools in the UK

Forge Code is a terminal-based AI pair-programmer and software-engineering agent that lets you interact with your entire codebase using natural language commands. It runs directly in your shell, integrating seamlessly with any IDE or existing workflow; you don’t need to switch editors or abandon your regular tools. Forge Code understands project files, Git history, dependencies, and environment context, so once it loads your project, it comprehends the codebase structure and can respond to prompts without repeated explanations. It offers a multi-agent architecture: a “Forge Agent” for implementing changes and real code execution, and a “Muse Agent” for planning, analyzing, and reviewing code without altering files. You can use Forge with your preferred AI provider or self-hosted LLMs, giving full control over where your code goes and how the model is run.

TypeUI is an open source command-line interface designed for agentic design, enabling developers to apply a consistent and structured design system across AI-generated code by generating and managing standardized files. It acts as a design layer for AI coding tools, ensuring that interfaces produced by different agents follow the same visual rules for typography, color, spacing, and component styling, regardless of the underlying model or provider. It addresses a key challenge in AI-assisted development, where outputs from tools like Claude Code, Cursor, Codex, or Gemini can vary significantly in style by introducing a portable design blueprint that enforces uniformity across projects. Through a simple CLI workflow, users can generate design systems by answering guided prompts, pull pre-built “design skills” from a registry, or update existing configurations without rebuilding them from scratch.
