Problem

Currently, the WebChat and Control UI do not support slash commands autocomplete. When users type / in the chat input, there is no dropdown or popup showing available commands.

Current Behavior

• Discord/Telegram: Native commands with autocomplete work well
• WebChat/Control UI: Users must type commands manually without any suggestions

Expected Behavior

When typing / in WebChat/Control UI:

1. Show a dropdown list of available commands
2. Filter the list as user types
3. Allow selecting a command from the list

Why This Matters

• Improves user experience, especially for new users who don't know all commands
• Makes WebChat/Control UI more competitive with native apps like Discord
• Reduces typing errors in command names

Possible Implementation

• Add a command dropdown component to the Vite + Lit Control UI
• Fetch available commands from Gateway (similar to how Discord does it)
• Could start with basic commands: /help, /status, /model, etc.

Environment

• OpenClaw version: 2026.3.2
• Platform: WSL2 on Windows
• Access: WebChat/Control UI at http://127.0.0.1:18789/
