Single tool with critical definition gaps. Tool name 'enforce_tenant_isolation' lacks action verb clarity (enforce is vague, does it create, validate, or apply isolation?). Description is present (94 chars) but generic and lacks WHEN/WHY guidance. Input schema visible but parameters lack descriptions entirely, tenant_id and execution_payload have no guidance on format, constraints, or expected values. Output schema undocumented; response structure inferred from code only. No error handling guidance. Tool appears to be a security/validation function but this is not explicit in the definition.

• Add descriptions to all input parameters. Example: 'tenant_id (string, required): Enterprise tenant identifier (UUID or domain name). Used to scope isolation boundaries and generate tenant_scope_token.' and 'execution_payload (object, optional): Container for user_prompt (string), session_variables (object with key-value pairs), and cross_tenant_token (string or null). If omitted, defaults to empty payload.'
• Document the output schema explicitly. Example: 'Returns object with fields: sandbox_status (string: SECURE_TENANT_ISOLATED or QUARANTINED_LEAK_DETECTED), tenant_id (string), tenant_scope_token (string, 16-char hex), cross_tenant_leak_detected (boolean), quarantined_variables (array of strings), isolated_memory_frame_ready (boolean).'
• Rename tool to 'validate_tenant_isolation' or 'check_tenant_boundary' to clarify that it validates/checks rather than enforces/applies. Update description to: 'Validates that an execution payload respects tenant isolation boundaries. Detects cross-tenant credential leakage and returns isolation status. Use this before executing untrusted agent code in a multi-tenant environment.'
• Add error handling guidance to description. Example: 'If cross_tenant_leak_detected is true, the payload contains forbidden variables (shared_*, root_admin, tenant_global). Quarantine the execution and ask the user to review session_variables. Do not proceed with execution.'
• Remove hardcoded example values from default execution_payload. Instead, document the expected structure in the parameter description and let callers provide actual payloads. Or use null as the default and document what happens when null is passed.
