How to use CTHINK and CREUSE: bank a chain of thought
CTHINK stores a reasoning trace as a reusable step graph; CREUSE fetches the matching plan for a new query at a fraction of the token cost.
The expensive part of a hard answer is the reasoning. CTHINK stores that reasoning's shape; CREUSE replays it for the next question with the same structure.
> CTHINK "amortize 12000 over 24mo at 6%" "step1: rate/12 ... step2: ... step3: payment="
OK
> CREUSE "amortize 8000 over 36mo at 5%"
"reasoning plan matched - substitute: principal=8000, n=36, apr=5 ..."The first solve pays full reasoning tokens; every structural sibling after pays only a recomposition.
