v2026.2.6-4

🖼️ Canvas Panel

Let your agent push images, diagrams, and rich content directly to your browser with the new canvas feature:

• Floating panel — Drag anywhere, dock to edges, or pop out to a separate window
• Local images without base64 — The /_canvas/ proxy serves images from your gateway's canvas directory
• All commands supported — present, hide, navigate, eval, and snapshot
• Multi-tab sync — Canvas state syncs across browser tabs automatically
• Works everywhere — Dev server, npm package, and Docker all include the canvas proxy

Enable it in Settings → Canvas Node, then agents can push content with:

nodes action=invoke node=<id> invokeCommand=canvas.present invokeParamsJson='{"url":"/_canvas/image.png"}'

📚 Documentation Site

New VitePress-powered documentation at maudecode.github.io/cove:

• Getting started guides — Installation, configuration, deployment
• Canvas setup — Step-by-step instructions for gateway and Cove
• Agent reference — Complete skill doc for using canvas from agents
• Auto-deployed — Updates on every push to docs/

🐳 Improved Docker Container

The Docker image now uses nginx with a proper canvas proxy:

• Smaller and faster — nginx serves static files efficiently
• Canvas proxy built-in — Configure with GATEWAY_HOST and GATEWAY_PORT env vars
• Rootless and secure — Runs as non-root with read-only filesystem
