Problem Statement

When using Remote Control from the Claude mobile app (iOS/Android), there is no way to execute slash commands like /compact, /clear, or /context. The mobile interface only supports natural language chat input.

This is a significant limitation for long-running Remote Control sessions:

1. Start a Claude Code session on desktop, enable Remote Control
2. Step away and continue monitoring/directing from mobile
3. Context window fills up during a long task
4. Cannot run /compact from mobile — forced to either wait for auto-compact (which produces lower quality summaries) or physically return to the desktop

Manual /compact with custom preservation instructions consistently produces better results than auto-compact. Losing access to this from mobile defeats a key part of the Remote Control value proposition.

Proposed Solution

Allow slash commands to be entered in the Remote Control mobile/web chat input. At minimum:

• /compact [instructions] — Manual context compaction with custom instructions
• /context — View current context usage
• /clear — Start fresh conversation

Possible implementations:

1. Recognize / prefix in the mobile chat input as slash commands (simplest)
2. A dedicated command menu button in the mobile UI
3. Quick actions via swipe or long-press for common commands
