The only private key that my agents have access to are temporary AWS access keys to a dev environment with decently locked down permissions.

I let it troubleshoot my web code using a temporary JWT in a dev environment using headless chrome and Puppeteer in a Docker container.

Everything else is in AWS Secrets Manager inaccessible by the IAM role the agent has access to.

I don’t store the temporary AWS keys in a file anywhere. They are in environment variables. All AWS SDKs and the CLI look in the environment variables by default.

I sure as hell don’t store API keys anywhere on my local computer.
