The 5-operation limit was overly conservative and unnecessary. Analysis showed:
- Workflow is cloned before modifications (no original mutation)
- All operations validated before any are applied (true atomicity)
- First error causes immediate return (no partial state possible)
- Two-pass processing handles dependencies correctly
Changes:
- Remove hard-coded 5-operation limit check from workflow-diff-engine.ts
- Update tool descriptions and documentation to reflect unlimited operations
- Add tests verifying 50 and 100+ operations work successfully
- Add example showing 26 operations in single request
The system already ensures complete transactional integrity regardless of
operation count. Bottleneck is workflow size, not operation count.
