Summary

Running /ultrareview <PR> from the Claude mobile app via Remote Control returns:

/ultrareview isn't available over Remote Control.

No fallback, no suggestion to run from desktop, no documentation warning.

Reproduction

  1. Connect Claude mobile app via Remote Control (/remote-control)
  2. Send /ultrareview 2 from mobile
  3. Hard error: '/ultrareview isn't available over Remote Control.'

Impact

Remote Control is explicitly designed for mobile-driven workflows. Excluding a major skill from it with no fallback or explanation defeats the purpose. Particularly painful when Desktop compact is broken (forces RC use) and you want to kick off a review while away from desk.

Expected behavior

Either: (a) allow ultrareview to queue/run from RC with a notification when done, or (b) at minimum respond with 'Run this from your desktop terminal: /ultrareview 2' instead of a hard block.

Environment

  • Claude Code v2.1.111
  • Claude iOS mobile app via Remote Control

extent analysis

TL;DR

Modify the Remote Control handling to either allow /ultrareview to run with notification or provide a fallback message suggesting desktop usage.

Guidance

  • Investigate the Remote Control configuration in Claude Code v2.1.111 to see if there's an option to enable or whitelist /ultrareview commands.
  • Consider adding a conditional check in the Remote Control code to detect /ultrareview commands and respond with a message suggesting the user run it from their desktop terminal instead.
  • Review the documentation for any existing parameters or flags that could be used to allow /ultrareview to queue or run from Remote Control with a notification when done.
  • Check if there are any open issues or feature requests related to enhancing Remote Control capabilities in Claude Code.

Example

No specific code snippet can be provided without more context on the Claude Code architecture, but a potential approach could involve modifying the command handler to include a conditional check for /ultrareview and respond accordingly.

Notes

The solution may require changes to the Claude Code base or the Remote Control implementation, and may involve trade-offs between security, usability, and functionality. The exact implementation details will depend on the underlying architecture and design of the Claude system.

Recommendation

Apply a workaround by modifying the Remote Control handling to provide a fallback message suggesting desktop usage, as this seems to be a more immediate and feasible solution given the current constraints.
