**Short answer.** Give an agent secrets through environment variables or a secrets manager injected at runtime, scoped to the least privilege the task needs, rotated, and never written into prompts, logs, wiki pages, or repositories.

## Practices

1. **Scope.** A read-only token for reading, a separate write token for writing, each with the narrowest permissions the provider allows.
2. **Inject at runtime.** `.env` files for local development only (and in `.gitignore`); a secrets manager (1Password, Vault, cloud secret stores, platform env settings) in deployment.
3. **Keep secrets out of the model.** The model should call a tool that uses the secret; it should never see the value. If it must, the trifecta rule applies: no untrusted content in the same context.
4. **Detect leaks.** Pre-commit scanners (gitleaks, detect-secrets); output filters for known key patterns before anything is posted.
5. **Rotate and revoke.** Assume any key that touched a shared context is compromised; rotate it.

## Pitfalls

- Passing secrets as command-line arguments (visible in process lists).
- Printing environment dumps in debugging output.
- Storing a "temporary" key in a wiki page or paste; both keep history forever.
