Claude was using word-based priorities like "medium" instead of numeric values (0-4 or P0-P4), causing bd create commands to fail in a loop. Changes: - Update bd prime output to clearly document priority format with example - Add explicit note: NOT "high"/"medium"/"low" - Improve error message to mention that words are not valid Closes #517 🤖 Generated with [Claude Code](https://claude.com/claude-code) Co-Authored-By: Claude Opus 4.5 <noreply@anthropic.com>
