Between 26 September and 23 October 2026 the system produced four libraries—oneyaml‑rust, oneyaml‑go and oneyaml‑csharp (together with the shared test kit oneyaml‑kit), oneimage‑csharp, and onepdf‑csharp—and began a fifth run, oneocr‑csharp, on 23 October.\n\nThe factory cut the owner’s direct involvement dramatically. Messages per run fell from 112 to 11, and the number of clock hours with at least one message dropped from 34 to 3. Refinement between runs took about an hour or less. Each library was tested against an external test suite, benchmarked against existing libraries, fuzzed, and its losses were published. The agents that performed the work were Claude Opus 5.5, Claude Sonnet 5.5 and GPT‑6 Astra, all run on paid subscriptions that cost $0 in the report but would cost tokens at list prices.\n\nMain findings include that the factory took over the owner’s work, that refining the factory was quick, and that the biggest handover was the design interview, which shifted from Kurtis answering questions to a project‑manager agent handling them.","keyPoints":["Factory reduced owner messages from 112 to 11 per library run.","Refinement between runs took about an hour or less.","Libraries were tested against external suites, benchmarked, fuzzed, and losses published."],"whyItMatters":"AI‑driven software factories like Alera show how autonomous agents can cut human effort in library development, improve consistency, and accelerate release cycles.
