as a second annectdote, at amazon last summer things swapped from nobody using llms to almost everyone using them in ~2months after a fantastic tech talk and a bunch of agent scripts being put together

said scripts are kinda available in kiro now, see https://github.com/ghuntley/amazon-kiro.kiro-agent-source-co... - specifically the specs, requirements, design, and exec tasks scripts

that plus serena mcp to replace all of gemini cli's agent tools actually gets it to work pretty well.

maybe google's choice of a super monorepo is worse for agentic dev than amazon's billions of tiny highly patterned packages?

I would think this is reasonable. My general understanding at Amazon is that things are expected to work via API boundaries (not quite the case at Google).
