Discover and Install

Search by name to install, update, or remove plugins. The bundled plugin list remains available offline, while installation and version checks require a network connection.

Plugin Updates

Bundled plugin updates preserve same-name plugins that you installed yourself and keep disabled plugins disabled. If an update fails, the previous plugin configuration is restored.

Included Plugins

Better Sidebar: side conversations, files, Git, local terminal, and previews.
GenUI: interactive interfaces, Mermaid, and Three.js rendering.
Skin Center: theme preview, apply, and restore.
Hindsight: opt-in long-term memory for selected projects.
Skills/MCP Manager: Skill controls and MCP connection management.

Permission Notice

Third-party plugins have the same Host permissions as the desktop app. Package signatures, permission manifests, and process-level sandboxing are not currently available. GitHub sources that require prepare, allowBuilds, or other install scripts need package-by-package review.
