Runtime

Hot reload

Re-applying config changes to a running agent in place, without restarting the process.

also known as: live reload

In depth

Edit a YAML file, save, the next agent turn uses the new config. No process restart, no re-imports, no rebuilt session state. On Digitorn hot reload runs in around 200ms, which is the difference between iterating on a prompt fluidly and batching changes because the loop is too slow. The single biggest productivity win of declarative agents.
