[Bug] Custom Slash Commands Intermittently Not Loading in Powershell

[nCubed]

Bug Description Custom slash commands are intermittently not loading; mostly not loading while using the Claude Code PowerShell version. For example, all of my custom commands in my home directory are able to be used, but none of the project commands. The custom commands had stopped working until I re-ran the claude installer. On the same machine with WSL/Ubuntu, all custom slash commands are available - both personal commands and project commands.

The current duplicate #7283 is purely *nix based. This is a PowerShell report. As mentioned in the bug, same machine the WSL/Ubuntu claude instance has no issues resolving slash commands.

Further, this issue is reporting the slash commands are mostly working with the personal commands; whereas the project level commands are no longer available.

What's odd is this was a fresh dev machine install and the PowerShell version worked w/o issue, and then just stopped. After a Claude .ps1 reinstall, the personal commands were available again, but project commands remained absent.
