SDLC assumed human pace. Agents flip it: implement is cheap, review/deploy floods.
Cloudflare ADLC: Workflows + agent CI + traces — short-lived creds / Trust Ratchet so the harness holds the keys.

I am rather proud of my React Advanced 2024 talk, "Expo Prebuild, Demystified", though I think few people have seen it.
I promise you you'll learn something new about Prebuild and Templates, even as an experienced Expo dev. Just look at these nice slides!

LLM routers seem like a fascinating pattern to me.
- Lets you separate concerns into different prompts
- Makes your system more testable
Really interesting for agents/workflows with several discreet concerns, like searching, handling git, and file editing.
