.env files

Blocked by the sandbox on purpose — describe them in the instructions file instead.

What is .env files?

.env files are blocked at the sandbox layer on purpose. The agent gets a written description of what's available; the values stay in the environment, outside the transcript.

.env files + Watchfire

  • .env files are blocked at the sandbox layer — the agent literally cannot read them.
  • This is intentional: it stops credentials from leaking into transcripts the agent might paste back into chat output.
  • Describe what's in .env via .watchfire/secrets/instructions.md; the agent gets the description, the runtime gets the values, the transcript stays clean.
