DF8400: Command Already Registered

Message

Command "{id}" is already registered

Cause

ctx.commands.register(command) was called with an id that another command already owns. Command ids are unique per hub context.

Fix

• Pick a different command id (namespace under your tool: my-tool:reload, my-tool:open-settings, …).
• To replace, call ctx.commands.unregister(id) first.

Source

• packages/hub/src/node/host-commands.ts — DevframeCommandsHost.register() throws when commands.has(command.id).
