Slash command autocomplete intermittently missing in Desktop with remote-control

Description

When using claude remote-control to connect Claude Desktop to a remote Claude Code instance, the slash command (/) autocomplete dropdown menu intermittently fails to appear in some conversations while working correctly in others.

Environment

• Claude Code version: 2.1.81
• Connection method: claude remote-control → Claude Desktop app
• OS (remote): Ubuntu 24.04 (Docker container)
• OS (local): Windows (Claude Desktop)

Steps to Reproduce

1. Start claude remote-control on a remote machine
2. Connect via Claude Desktop app
3. Open a new conversation and type / in the input field
4. Slash command autocomplete dropdown appears correctly
5. Open another new conversation and type /
6. Slash command autocomplete dropdown does NOT appear

Expected Behavior

The slash command autocomplete dropdown should consistently appear in all conversations when typing /.

Actual Behavior

• Some conversations show the autocomplete dropdown normally (with all registered skills: update-config, debug, simplify, batch, loop, schedule, claude-api, changelog, memory-update, readme-project, train-analyze, train-evaluate, etc.)
• Other conversations in the same Desktop app, connected to the same remote instance, do not show the dropdown at all

Screenshots

Working session ("Initial project setup and configuration"):

• Slash command dropdown appears with full skill list

Non-working session ("Debug skill availability issue in Claude..."):

• No dropdown appears when typing /

Both sessions are connected to the same remote machine (ksm-MS-7E01).

Notes

• Skills themselves work fine when invoked programmatically (via the Skill tool) even in sessions where the autocomplete UI is missing
• The issue appears to be a Desktop UI-side problem, not a server-side skill loading issue
• No --disable-slash-commands flag is set
• All plugins are properly enabled in settings.json
