I work at AWS, we got access to Claude Code very recently, most people are using Kiro and that seems to be the defacto standard.

I have not heard of any nor run into any token budgets.

There is generally a lot of team-wide usage of CLAUDE.md/AGENTS.md, team-specific skills, oncall skills, etc.

Not as much org-wide, although my org has an MCP server built for helping with oncall.
