Quand l'utiliser : You have an app and want Figma-style 'who's here' indicators without running a socket server.
Prérequis
Skill copied into your project's .claude folder — git clone https://github.com/PolarCoding85/convex-agent-skillz and copy .claude/ to your project root
Déroulement
Describe the feature
Using the Convex skillz — add presence to the documents page. Show cursors and usernames.✓ Copié
→ Claude implements with Convex's presence pattern (mutation + reactive query), not a custom WebSocket
Handle disconnection
What about cleanup when users close the tab?✓ Copié
→ Specific stale-presence cleanup strategy aligned with Convex conventions
Résultat : Working presence with proper cleanup.
Pièges
Custom presence pattern that fights Convex's reactivity — Skill steers you toward the idiomatic version; don't override without a reason
