Show HN: PlateSpinner – A Kanban board that orchestrates AI coding agents

PlateSpinner is a local web app that manages AI coding agents through a kanban board. You point it at a project directory, describe what you want, and it spawns headless Claude Code / Codex / Gemini sessions to generate tasks, plan implementations, and write code.

The workflow is: Propose → Plan → Execute. Generation and planning run in read-only mode. Execution gets full write access, creates branches, commits changes, and captures diffs for review. There's also an "autoclicker" mode where an AI judge continuously decides what to do next, propose, plan, or execute, so you can just watch.

Built with React + Express + WebSocket. It doesn't call any cloud APIs directly — it shells out to the CLI tools the same way you would from a terminal.
