What's Wrong?

It seems the latest version of Claude Code "broke" agents a bit.
If you have personal agents called 'openai' (openai.md) and 'google' (google.md) in /Users/user/.claude/agents, they no longer show up with @agent-...

The rest of the agents seem fine, so it seems something specific to these?

What's strange is that it does see the file as a "+..." under the new output, but not as a "*..."

What Should Happen?

Agents should get called

Steps to Reproduce

Create an agent 'openai.md' in /Users/user/.claude/agents and then launch claude cli and try to use it with @openai or @agent-openai -- it will not find it. It will find the file for the agent instead...
