-Trixie WebAssembly plugin for VTube Studio
+This repository contains the independently versioned VTube Studio integration
+for Trixie. It produces a WebAssembly plugin package consumed by the Trixie
+server; it is not part of the Trixie server source tree.
+
+## Boundary
+
+The plugin may only use capabilities explicitly exposed by the versioned
+Trixie plugin host API. It must not open arbitrary network connections, access
+the filesystem, execute processes, read secrets, or evaluate user-provided
+code. VTube Studio-specific behavior belongs here; installation, validation,
+permissions, secret approval, lifecycle, limits, and isolation belong to the
+Trixie server.
+
+The initial scaffold is intentionally inert. The local VTube Studio WebSocket
+connection, user approval/token flow, and action schemas will be added only
+after the host contract and security review are complete.
+
+## Development
+
+Work on `dev`. Build the current scaffold with:
+
+```text
+rustup target add wasm32-unknown-unknown
+cargo build --target wasm32-unknown-unknown --release
+```
+
+Do not place Twitch credentials, VTube Studio tokens, or generated plugin
+packages in this repository. See the Trixie plan and server plugin contract
+documentation for the integration boundary.
