AI coding agent for VS Code, powered by the Dropstone engine. Dropstone reads, writes, and refactors code in your workspace, runs commands, and explains what it did — with every file change shown as a reviewable diff.
- Agent modes — Build, Plan, Accept All, and Discovery, switchable per message.
- Model + effort control — pick the model and how hard it should think.
- Diff review — edits and writes render as inline diffs before you accept them.
- Permission prompts — tool calls that touch your machine ask first.
- Images — attach or paste screenshots straight into the composer.
- Slash commands —
/for built-ins plus any commands your workspace defines. - Chat history — resume, rename, or delete past sessions.

The engine downloads automatically on first use and keeps itself up to date.
