I paid that bill once — a nine-year experiment in splitting a platform across twelve separately-owned teams — and here is what it taught me about why the agent count is a cost you pay, not a capability you gain. multi-agent-systems ai-orchestration agentic-ai context-engineering distributed-systems system-design https://francescocolamonici.it/en/blog/a-boundary-you-dont-enforce-is-just-a-wish https://francescocolamonici.it/en/blog/a-boundary-you-dont-enforce-is-just-a-wish Tue, 11 Aug 2026 00:00:00 GMT I opened my own repo and found that the rule meant to police my architecture enforced nothing. Here is how I turned it into a fitness function that fails the build when any code — human or AI — crosses a line it shouldn't. architecture-fitness-functions module-boundaries evolutionary-architecture ai-assisted-development system-design https://francescocolamonici.it/en/blog/decisions-you-dont-write-down-become-debt https://francescocolamonici.it/en/blog/decisions-you-dont-write-down-become-debt Tue, 04 Aug 2026 00:00:00 GMT In 2016, on my first architecture assignment, a mentor told me documentation was a deliverable as important as the code. Here is why the architectural decisions you don't write down always come back as debt. software-architecture decision-records technical-debt system-design
