[BUG] Plan output in terminal shows only headers, not full content

What's Wrong?

When Claude creates a plan file, the terminal output sometimes shows only the section headers (skeleton), but the actual plan file contains the complete content.

This is sporadic behavior - it doesn't happen every time. My CLAUDE.md instructions tell Claude to use XML tags for structuring plans. This may be relevant to reproducing the issue, as the XML content appears to be stripped from the terminal display.

Terminal shows only headers with no content:

Plan saved to: ~/.claude/plans/example-plan.md
Plan: Implement Feature X

Context

Requirements

Implementation Steps

Files to Modify

Verification

However, opening the actual file reveals the complete plan with full content under each section (XML-structured content in my case).

What Should Happen?

Terminal output should show the actual plan content, or at least indicate that content exists under each header.

Steps to Reproduce

1. Add instructions to CLAUDE.md telling Claude to use XML tags for structuring plans
2. Start Claude Code in plan mode
3. Have Claude create a plan
4. Observe the terminal output - sometimes only headers are shown while the file has full content

Additional Information

This is confusing because users see an apparently empty plan in the terminal, making it look like the plan generation failed or produced no useful output. Users have to manually open the file to see the actual plan.
