What's Wrong?

When I ask Claude Code to read out the full tool schema for the Skill Tool, it does this (i cut off my actual skills)
<img width="911" height="447" alt="Image" src="https://github.com/user-attachments/assets/02234a8a-8802-45c0-b1b3-17e85964237e" />

But doing the same for the Task tool does this:

Funny enough this actually makes a lot of sense as to why custom subagents are never invoked proactively by Claude.

What Should Happen?

Task Tool shouldn't ignore .claude/agents in its schema

Steps to Reproduce

1. Add a custom subagent to .claude/agents
2. Add a custom skill to .claude/skills
3. Open a Claude Code chat and ask it to list out the full tool schemas for Task tool and Skill tool
4. >Task Tool will ignore custom subagents, but Skill
