The Cube maps six cognitive frameworks to the six faces of a Rubik's cube. A problem is placed at the core. The cube rotates through geometric combinations:
- 6 Faces (individual framework analysis)
- 12 Edges (adjacent-pair cross-analysis)
- 3 Axes (opposite-pair dialectics)
- 8 Corners (triple-framework triangulation)
= 30 total analysis points, followed by grand synthesis.
Front (F): Inversion Back (B): First Principles
Left (L): Steelmanning Right (R): Second-Order Thinking
Up (U): Pre-Mortem Down (D): Boundary Conditions
Each stack is a complete Rubik's cube with 6 domain-specific frameworks, unique edge/axis/corner names, and the same 30-position rotation protocol.

When modifying skills:
- Each skill file must remain self-contained (all instructions in one file)
- Every analysis point must have a clear self-prompt for Claude to follow
- Maintain cube geometry consistently (faces, edges, axes, corners map to real positions)
- Position numbers (1-30) must stay sequential and match the output format
- Key Insight tags are required after every analysis position
- Phase transition markers are required between phases
- Cross-references between positions should be used when later rotations connect to earlier ones
- Edge rotation descriptors must explain both methodologies for non-practitioner scaffolding
Feedback is saved to .cube/feedback/ via the /cube-feedback skill. This data stays local. Users can opt to share it via GitHub issues.
