Credentials and Identity Boundaries
If your application uses NexoToken model API access, consult the current main platform documentation for credential setup, authorization scope, and revocation. Do not infer endpoint paths or authentication fields. Keep credentials in a server-side secret manager, separated by environment, and inject them at runtime. Never place them in client bundles, browser storage, source control, error responses, or analytics logs. Authenticate your application’s user independently of the model request, and derive the user and tenant from a verified session rather than caller-supplied fields. If the current design requires a browser to hold a credential, pause release and move the call behind a controlled server-side service. If exposure is suspected, revoke and replace the credential, then review relevant records before resuming traffic.
Authorization and Tool Scope
Enforce authorization in application code before every model call and every tool execution. Check the authenticated user, tenant, resource ownership, and requested action; do not treat model output, prompt text, or a front-end role claim as permission. Allow only the tools needed for the current workflow, and validate their arguments with explicit types, size limits, ownership checks, and permitted operation scopes. For a hypothetical invoice-reading tool, the server should select the tenant from the verified session, not from a tenant identifier generated by the model. If ownership is missing or ambiguous, fail closed: deny the operation, return a safe error, and record the reason without sensitive payloads. Recheck authorization at execution time in case the underlying resource or session state has changed.
Prompt Injection and Data Minimization
Treat user messages, retrieved documents, and tool results as untrusted input, including text that asks the application to ignore policy, reveal secrets, or invoke additional tools. Keep trusted instructions distinct from quoted or retrieved content, but do not rely on prompt wording as the enforcement boundary; application code must still authorize each action. Before sending context, remove credentials, personal data, and fields that are unnecessary for the task. Inspect generated or tool-derived content before displaying or acting on it, and prevent sensitive values from entering user-facing output or logs. For a hypothetical test, place an instruction to disclose hidden policy inside a retrieved document. Define the expected outcome in advance: no secret is disclosed and no unauthorized tool runs. Run the check yourself, record the actual result, and revise the boundary if it fails.
Release Checks and Audit
Build a checklist around your own threat scenarios and run it in an isolated environment before release. Include attempts to read another tenant’s data, pass unauthorized tool arguments, forge identity fields, and inject instructions through retrieved content. For every case, record the expected decision and the observed application behavior; do not describe a check as passed until you have run it. If any case bypasses server-side authorization, exposes a secret, or leaves sensitive material in logs, block release, fix the control, and repeat the affected checks. Consult current main platform documentation when interpreting NexoToken account platform usage history and credits. Compare only records whose available fields can actually be matched to your application logs; a credits change alone does not prove that a request succeeded or that your application enforced authorization correctly.
