Akka empirically tested a spec-driven AI porting workflow across 65 open-source projects, finding that structured specifications significantly improved first-pass implementation quality. While 57 projects saw gains in code size or performance, the study revealed that using Opus saved ~40% tokens compared to Sonnet but doubled the time, indicating diminishing returns on increased computational effort.

    • Structured specifications (declarations, evidence, typed behaviors) significantly improve first-pass AI implementation quality; lack of cross-component context is the main bottleneck.
    • Opus saves ~40% tokens compared to Sonnet but doubles execution time; increasing workload settings does not yield sustained efficiency gains.
    • 57 out of 65 projects showed improvements in code size or runtime performance, though extreme outliers like Dify's 143,333x speedup require careful interpretation due to workload differences.
