Single tool 'nbox_get' has a clear verb-noun name and reasonable description (95 chars), but critical gaps undermine quality. The input schema is visible with 5 parameters, all typed as strings with descriptions. However, the output schema is completely undocumented, no return type, structure, or field definitions are visible in the source. This violates the baseline that 100% of A+ tools have documented return types. The tool accepts optional scope disambiguators (vrf, site, group) but lacks enum constraints or validation guidance. No error handling documentation exists, the tool provides no recovery guidance for invalid references or ambiguous lookups. The description mentions 'optional scope disambiguators' but does not explain when or why to use them, or what happens if multiple matches exist. READ_ONLY risk classification is correct but tool annotations (readOnlyHint) are not present in the schema.

• Document the complete output schema with all fields, types, and examples. E.g., 'Returns: {object_type: string, name: string, slug: string, details: object}'. This is required for LLM planning.
• Add error handling guidance to the description: 'If reference is ambiguous, returns error with available matches. If not found, suggests similar objects by name.'
• Clarify the 'kind' parameter with an enum of valid values (device, prefix, ip-address, etc.) and explain what each returns.
• Explain when to use scope disambiguators: 'Use vrf/site/group to narrow results when reference matches multiple objects. If omitted, returns error if ambiguous.'
• Add readOnlyHint annotation to the schema to signal to agents that this tool is safe to call without side effects.
