[BUG] Slash command does not expand @/file references when placed in command body or description

[jwadow]

Problem (one or two sentences)

Slash commands fail to attach or expand @/file references when they are included in the command description or body. The files remain as plain text instead of being included in the context.

Context (who is affected and when)

Affects all Roo Code users who rely on slash commands to include multiple files or documentation snippets via @/ mentions. This occurs when running custom commands from .roo/commands/ that reference project files.

Reproduction steps

Create a file .roo/commands/attachfiles.md with the following content:

---
description: "Load docs files"
---

@/ARCHITECTURE.md  @/README.md  @/TODO.md  
Did you receive my files and their contents?

Write /attachfiles in Roo Code input.

Expected result

The @/ARCHITECTURE.md (and other) reference should expand into an attached file or inline content (like when manually typing @/ARCHITECTURE.md in chat). The file’s contents should be included in the context for the model.

Actual result

The model responds "Roo said: Yes, I received the files and their contents. Task completed." — but in reality, the model never receives any file contents.

Variations tried (optional)

• Placing @/ARCHITECTURE.md in frontmatter (description) → not expanded.
• Moving @/ARCHITECTURE.md to the command body → still not expanded.

Thank you for taking the time to write this up. Closing this issue since slash commands have never supported attaching files via @/file references, and this isn’t a planned feature at the moment. As a workaround, you can add the files directly to the rules folder so they’re included automatically.
