Troubleshooting
What to do when your agent cannot reach the Designless app, finds no brand, or the Agent-Native Canvas never opens.
Ask the Designless Agent
/designless My last request did not work. Tell me what went wrong and how to fix it.
If the agent cannot answer, find the message you see below.
"The Designless desktop app isn't reachable" or "Not authenticated"
Open the Designless app and sign in, then reconnect the server (in Claude Code, from the /mcp panel) or start a new session.
The plugin connects through the app, so the app needs to stay open and signed in.
"No brands found"
Run /designless and ask for a new brand to get started.
"Capsule not published"
Run /designless and ask to publish; the agent walks you through the quality gate.
The canvas never opens, or you installed the plugin on its own
The canvas renders in the Designless app, which is a separate install. Sign in at designless.app, or create an account, and download the app from the user menu; it is not offered on the signed-out page. Open the app and sign in there, then run /designless again.
macOS asks to install developer tools
Adding a marketplace from a terminal makes Claude Code and Codex fetch it with git. On a Mac without Apple's command line developer tools, macOS asks to install them first; install from the Designless app instead, which needs neither.
Still stuck
You can ask a more specific follow-up or contact support@designless.io. Include what you have already tried so the team can continue from that point.
