SPARC Architecture + Implementation Run Phases 2 and 3 of the SPARC methodology: design algorithms with pseudocode, then establish architecture with module boundaries and API contracts. When to use After the Specification phase is complete and its gate has been passed. This skill covers both the Pseudocode and Architecture phases as they are tightly coupled — algorithm design informs module boundaries and vice versa. Steps 1. Retrieve specification — call with namespace and query for the feature's spec. Extract requirements, acceptance criteria, constraints, and edge cases. 2. Retrieve phase…
