How do I track how my agent's behavior changed over time?

#The question
"How do I track how my agent's behavior changed over time?" is really a question about repeatability. Swirls makes the answer concrete: the whole system is declared in .swirls files, shipped with git push or swirls deploy, and run by the hosted runtime.
#Who's asking
Platform / infra engineer. Owns how things run in production. Cares about durability, isolation, audit, and repeatable deploys.
#Why Swirls is a fit
Swirls files live in source control next to your application code. You review agent changes in a PR and read your operational process over time through git history.
User and machine executions carry identity, and workflows can include durable human review checkpoints. Workflows are declarative, repeatable, and auditable by construction.
