Agents that run software need a context graph of the app: every resource, what it connects to, the repository that deploys it and the team that owns it. How we built one on Durable Objects, keep it fresh across every provider without polling AWS, decide what counts as a change, and delete from it safely.

Aleksandr Diamond and Boris Tane Cloudflare Durable Objects run in V8 isolates with a hard 128 MB limit. Ours idled at ~140 MB and was reset ~300 times a day. 130 MB of zod schemas were built at module load, most of them by code that was never called. How we profiled the production bundle, the two fixes, and the numbers, 218 MB to 82 MB and resets to zero.
