Plandex
Overview
A terminal-based AI coding agent designed for complex, large-scale tasks. Plandex coordinates multi-step plans across your entire codebase, handling everything from architectural refactors to new feature implementation autonomously.
Plandex is a terminal-based agent built for big, multi-step tasks that exceed what a single prompt can handle. It maintains a persistent plan and a sandboxed change set so you can review, refine, and apply work incrementally without polluting your working tree. Its diff-review sandbox and long-horizon planning make it well suited to migrations and deep technical-debt cleanup.
