[DOCS] Remote Control docs missing `@`-file autocomplete coverage

Documentation Type

Missing documentation (feature not documented)

Documentation Location

https://code.claude.com/docs/en/remote-control

Section/Topic

Remote Control capabilities when using claude.ai/code or the Claude mobile app

Current Documentation

The Remote Control page currently says:

With Remote Control you can: Use your full local environment remotely: your filesystem, MCP servers, tools, and project configuration all stay available Work from both surfaces at once: the conversation stays in sync across all connected devices, so you can send messages from your terminal, browser, and phone interchangeably

Later, the page says:

Use Remote Control when you're in the middle of local work and want to keep going from another device.

No documentation on this page currently explains that Remote Control clients can query @-file autocomplete suggestions from the connected local session.

What's Wrong or Missing?

Changelog v2.1.113 added this user-facing behavior:

Remote Control clients can now query @-file autocomplete suggestions

The current Remote Control documentation does not mention this capability anywhere.

That leaves users without documentation for:

A. Remote @-mention discovery

The docs do not say that typing @ from a Remote Control client can request file autocomplete suggestions from the local project.

B. How this relates to existing @ file mentions

The docs already describe @ as the trigger for file path autocomplete in interactive sessions, but the Remote Control page does not connect that behavior to browser/mobile Remote Control clients.

Suggested Improvement

Add a short subsection to https://code.claude.com/docs/en/remote-control, near the capability overview or connection workflow, such as:

Use @ file autocomplete from Remote Control

Explain that when a Remote Control session is connected, typing @ in claude.ai/code or the Claude mobile app can query file autocomplete suggestions from the connected local session.

The new text should also:

• link to https://code.claude.com/docs/en/interactive-mode for the general @ file mention behavior
• clarify that suggestions come from the local session/project available through Remote Control
• note this as part of the browser/mobile Remote Control experience, not just terminal-local interaction

Impact

Medium - Makes feature difficult to understand
