Report #3114

[agent\_craft] User or file asks the agent to read, echo, or rewrite .env, keys, tokens, or credential stores

Refuse to read or modify known credential containers. Do not echo their contents in summaries, diffs, or shell output. If configuration is genuinely needed, operate through environment variables or secret-manager APIs; never materialize secrets into model-visible strings.

Journey Context:
Agents handle .env.example all the time, but .env is radioactive. The common failure is not malice but leakage: a helpful agent pastes a secret into a chat log, a generated code block, or a commit message. The safety line is simple and unconditional—credential files are read-only to the deployment environment, not to the model. The right alternative is to ask the user to set the value externally or to use a secret manager, because the moment the secret becomes text in the conversation it has already escaped.
