| name | thinkies-decompose |
| description | Break a whole into parts at its natural joints |
Follow these steps:
1. State the whole
State what is being examined.
2. Identify part-whole relations
For things: components, members, portions, materials, phases, qualities, places. For tasks and problems: subgoals, cases, constraints, epistemic status (know / assume / verify / ask). Select only the relations that fit.
3. Find the natural joints
Find where boundaries already exist. A cut sits at a joint when the interface stays small, the parts change for independent reasons, and properties change abruptly at the line.
4. Verify coverage and connections
Do the parts account for the whole — no gaps, no overlaps? How do parts relate to each other?
5. Recurse
Recurse into parts that are still too complex, naming the relation type at each level — part-of does not compose across types. Set up todos and call the thinkies-decompose skill on those parts as well.
6. Stop at simple
Stop when a part can be acted on or verified directly, or when further cutting grows the interfaces more than it shrinks the parts.
