- Create .claude/skills/FLOWCHART_MODIFICATIONS.md with patterns for:
- Adding checkpoint nodes (variables, edges, Mermaid content)
- Conditional skipping with skipIf and excludeSkipFromPaths
- Understanding path enumeration and grid dimension stability
- Working problem evolution
- Debugging tips and modification checklist
- Add reference in CLAUDE.md under Flowchart Walker System section
This captures lessons learned from the fraction flowchart sprint where we
split CALCULATE into separate inputs and added conditional whole number skipping.
