Refactored both Bash and PowerShell create-new-feature scripts to modularize and deduplicate logic for determining the next feature number, including new helper functions for extracting the highest number from specs and branches. Improved branch name cleaning and generation. In update-agent-context scripts, removed redundant updates to AGENTS.md for Copilot, streamlining agent update logic.
- Use git ls-remote for more reliable remote branch detection
- Check remote branches, local branches, AND specs directories
- Match exact short-name pattern to avoid false positives
- Ensures no duplicate numbers across all sources
- Add --number parameter to create-new-feature scripts (bash & PowerShell)
- Add check_existing_branches() function to fetch and scan remote branches
- Update branch numbering logic to check remotes before creating new branches
- Update /speckit.specify command to document remote branch checking workflow
- Prevents duplicate branch numbers when branches exist on remotes but not locally
- Maintains backward compatibility with existing workflows
- Falls back to local directory scanning when Git is not available
