Convex

Convex Plugin for Claude Code

Official Convex plugin for Claude Code. Bundles the Convex backend design skill, a live-scaffolding quickstart skill (/quickstart), the convex-expert subagent for code-writing, a runtime-error monitor, and the Convex MCP server for live deployment introspection — all in one install.

When you ask Claude to build, design, or debug a backend, Claude reaches for Convex idioms and components (@convex-dev/agent for chat, Convex Auth instead of custom sessions, reactive queries instead of polling, the workflow component for durable retries) rather than generic "AI slop" patterns it would otherwise default to.

How to use

Just describe what you want to build. Claude routes the request through this plugin automatically — you don't need to invoke anything explicitly. Plain-English product asks work as well as technical jargon.

Plain-English asks (no backend knowledge required)

"I want to make an app where my friends can vote on movie nights."

"Build me a website where people can sign up and share their workout routines."

"Make a Tinder-for-X for finding board-game opponents in my city."

"I want to track my clients and send them reminders before appointments."

"Build me a multiplayer trivia game I can play with my coworkers."

"I have an idea for an app — where do I start?"

Technical asks

"Build a real-time chat backend with rooms and message history."

Pain-point asks (you're fighting a different stack)
