What's Wrong?

When running /ultraplan from the project root in CLI, the remote plan agent consistently resolves to the wrong workspace. The plan files and project context never reach the agent, so it operates blind.

What Should Happen?

Plan agent should inherit the current project workspace and have access to all plan files and context. Or require a github repo creation and provide that to the remote agent.

This is especially frustrating since Claude Code itself recommends /ultraplan as a workflow. Shouldn't require manual workarounds for a suggested feature.

Steps to Reproduce

• Launch Claude Code CLI in a project root (where .claude/ exists)
• Run /ultraplan
• Plan agent spawns but has no access to plan files or project context
• Always routes to the same incorrect workspace (deterministic, not intermittent)
