From Coding Assistants to Agentic IDEs

The difference between a coding assistant and an agentic IDE is not just a matter of capability — it’s architectural. A coding assistant responds to prompts. An agentic system operates in a closed loop: it reads the current state of the codebase, plans a sequence of changes, executes them, and verifies the result before reporting completion. That loop is what makes the tooling genuinely useful for non-trivial work.

Agentic CLIs

Most of the conversation around agentic AI focuses on graphical IDEs, but the CLI tools are worth understanding separately. They integrate more naturally into existing scripts and automation pipelines, and in some cases offer capabilities the GUI tools don’t.

The main options currently available:

Claude Code (Anthropic) works with the Claude Sonnet and Opus model families. It handles multi-file reasoning well and tends to produce more explanation alongside its changes, which is useful when the reasoning behind a decision ...
