VS Code Agent Kanban is a new extension that brings structured task management to AI-assisted development workflows. The tool addresses a common pain point: context rot in AI coding agents where conversations and decisions disappear when chat sessions are cleared or context limits are reached. Built as a VS Code extension, it provides a Kanban board and markdown-based task system that integrates directly with GitHub Copilot Chat.

The extension uses simple markdown files stored in a .agentkanban/ folder as the source of truth for each task. Each file contains YAML frontmatter tracking the task's state and a conversation log with [user] and [agent] markers. This approach makes task history permanent, searchable, and version-control friendly. The system works with existing AI tools rather than replacing them, contributing a @kanban chat participant that opens task files and injects context into standard Copilot sessions.

Key features include a plan/todo/implement workflow where developers can guide AI agents through structured phases, a visual Kanban board for task tracking, and GitOps-friendly design that preserves decision history. The extension is available now on the VS Code Marketplace and works with GitHub Copilot's native agent mode, keeping existing workflows intact while adding memory and structure to AI development sessions.
