plandex

Why we included this project

Plandex is a terminal-based coding agent built for the kind of work that breaks simpler assistants: multi-step tasks that touch dozens of files. It keeps a 2M-token context window and uses tree-sitter project maps to index very large directories, so it can hold a big codebase in view without losing the thread. Changes land in a cumulative diff review sandbox first, where you can inspect, roll back, and debug before anything reaches your real files. You can dial autonomy up or down, let it run build and test commands and fix failures on its own, and mix models from Anthropic, OpenAI, Google, and open-source providers. There's also a project-aware chat mode for exploring a codebase and working through ideas before you commit to an implementation.
