Terminal (CLI) coding agent
A coding agent that runs in the shell, not an IDE (Claude Code, Codex CLI, Aider, Gemini CLI), working on the whole repo and running commands.
Terminal agents skip the editor: you describe a task and the agent reads files, edits them and runs tests in your shell. They compose with existing tooling and CI, and are the surface where automation dominates — 79% of Claude Code sessions are the agent doing the task rather than assisting. Stack Overflow 2025 found 40.8% of developers using off-the-shelf agents used Claude Code.
