The software factoryAn autonomous software factory is a repeatable development system that coordinates agents, tools, checks and human review to turn specifications into verified software changes. described here is not a particular model, coding harness or commercial product. It is a model-agnostic operating system for AI-assisted developmentAI-assisted software development uses AI systems to help plan, write, test, review or maintain software while people retain responsibility for the result., encoded in project instructions and reusable skills so agents follow the same development process each time.
The workflow begins by isolating every feature in its own Git worktreeA Git worktree is an additional checked-out working directory linked to one repository, allowing separate branches to be edited side by side. and branch, which lets multiple agents work in parallelParallel agentic software development assigns separate bounded software tasks to isolated AI agent sessions that work concurrently and later integrate their results. without overwriting one another. A code-structure skill then steers implementation toward a maintainable service-layer architecture that people and later agents can understand.
VerificationAgent completion verification checks evidence that an agent achieved the requested outcome rather than merely producing intermediate work. is treated as part of the build rather than a final promise. Agents capture before-and-after evidence or measured test results, then an external code-review agent scores the pull request and sends unresolved issues back through the build and proof stages until the required quality threshold is met. Human intervention is reserved for the final review and merge.
