Imza

Imza is a terminal coding agent that provides plan, build, and review modes for software development.

Imza is a terminal coding agent built to keep developers directly involved in codebase changes through explicit plan, build, and review modes. It operates as a native C++ application with a small memory footprint and terminal user interface. The agent investigates repositories, designs changes in Markdown spec documents, streams diffs in real time, and supports sandboxed Lua tool execution to minimize context overhead. It includes Model Context Protocol support, bring-your-own-model capabilities for OpenAI-compatible and Anthropic endpoints, and headless execution for CI scripts. Developers can use path and skill attachments, sidechats, and permission controls to manage file and shell access.
