Show HN: enveil – hide your .env secrets from prAIng eyes

[dead]

This doesn’t really fix that it can echo the secrets and read the logs. `enveil run — printenv`

Alternative, and more robust approach is to give the agent surrogate credentials and replace them on the way out in a proxy. If proxy runs in an environment to which agent has no access to, the real secrets are not available to it directly; it can only make requests to scoped hosts with those.

I’ve built this in Airut and so far seems to handle all the common cases (GitHub, Anthropic / Google API keys, and even AWS, which requires slightly more work due to the request signing approach). Described in more detail here: https://github.com/airutorg/airut/blob/main/doc/network-sand...

Sometimes I need to give Claude Code access to a secret to do something. (e.g. Use the OpenAI API to generate an image to use in the application.) Obviously I rotate those often. But what is interesting is what happens if I forget to provide it the secret. It will just grep the logs and try to find a working secret from other projects/past sessions (at least in --dangerously-skip-permissions mode.)
