Thought Decomposition Specification

Data artifactCognitionCognition & Memoryarc:ThoughtDecompositionSpec

A design artifact defining what constitutes one thought for a problem class (e.g., one arithmetic operation, one narrative plan, one crossword word), fixing tree granularity.

Responsibility. Defines the intermediate-thought unit that shapes generation and evaluation.

Also known as: Thought granularity definition, Thought decomposition strategy

Design guidance

MUST place thought boundaries at natural breakpoints where genuinely distinct candidates exist and meaningful evaluation is possible.
SHOULD keep search tree depth manageable (typically under six levels).
SHOULD be validated on small problem samples before full implementation, since decomposition errors are expensive to correct later.

Classification

Patterns: Operation-level decompositionPlan-level decompositionWord-candidate decomposition
Risks mitigated: Intractable search spaces from too-fine thoughtsLoss of exploration from too-coarse thoughts
