What's Wrong?

## Description

The /agents dialog in Claude Code displays built-in tools with incorrect/missing categorization:

• Read, Grep, Glob, Write, Edit — shown as "Uncategorized"
• AskUserQuestion — shown as "Unrecognized"

All tools function correctly — this is purely a display/classification issue in the agents dialog UI.

## Steps to Reproduce

1. Open Claude Code
2. Run /agents
3. Observe the tool inventory list

What Should Happen?

## Expected Behavior

Built-in tools should either:

• Be grouped under a named category (e.g., "Built-in" or "Core Tools")
• Or be excluded from the listing if they're system-level tools not meant to be shown

Error Messages/Logs

## Actual Behavior

  - Core file tools (Read, Grep, Glob, Write, Edit) appear under "Uncategorized"
  - AskUserQuestion appears as "Unrecognized"

Steps to Reproduce

The issue is that when you open the /agents dialog (or /plugin), the tool inventory categorization is off. But I don't
know the exact UI flow you followed to see "Uncategorized" and "Unrecognized" — it could be /agents, /plugin, or a
specific tab/section within those dialogs.
