From One Factory to a Two-Story Harness: How a Dev Pipeline Grew in Under a Year
The author describes building a multi-agent development factory that evolved into a system of nearly ten parallel pipelines with a two-layer harness – top-level control and local gates per factory. Key principles: ratchet (failures become permanent fixes), sensor-first (invariants as detectors before rules), and measurability (rules must change behavior). The system is not tied to Cursor; it uses open standards like Skills, AGENTS.md, and MCP.
