patchmill

Patchmill is an agent-driven software factory for turning product work into reviewed, landed changes without hiding the engineering judgment between idea and production.

It connects an issue host, repository policy, git worktrees, and configurable agent skills so teams can triage issues, plan work, implement in isolation, review results, collect evidence, and land changes with clear handoffs.
