docs: Claude Code v2.1.211 - /config behaves differently on web and desktop vs mobile

[claude-yolo]

Night shift report

WHY THIS MATTERS: The docs previously implied /config key=value works everywhere, but it doesn't — on claude.ai/code and in the Desktop Code tab, /config opens the Settings UI instead of setting values, and any text after the command (including key=value pairs) is silently ignored. Only the mobile app via Remote Control actually accepts key=value. This correction matters because users who try /config theme=dark in a cloud session or Desktop will wonder why nothing happened. The fix also adds guidance: use environment variables or committed settings files to configure cloud sessions instead.

HIGHLIGHTS:

• /config on web (claude.ai/code): opens Settings → Claude Code; key=value arguments are ignored — use env vars or settings files in the repo instead
• /config in Desktop Code tab: same — opens Settings → Claude Code, text after command is ignored; only the picker form was unavailable before, now the key=value form is also clarified as a no-op
• /config on mobile (Remote Control): still works as before — pass key=value to set a setting, or run with no argument to list settable keys
• /commands.md: minor wording fix — "Remote Control" clarified as "Claude mobile app via Remote Control"
• Bulk of other file changes (60+ support files): CDN image signature URL rotation — pure noise, no content change
