approve_sender_id

Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?

No annotations are provided, so the description bears full responsibility. It discloses the auth requirement (X-API-VASKEY) and the mutation action. However, it lacks details on side effects, rate limits, or error states, which would improve transparency.

Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

Is the description appropriately sized, front-loaded, and free of redundancy?

The description is a single, focused sentence. It front-loads the HTTP method and endpoint, then immediately conveys the core purpose. Every word is necessary and no extraneous information is present.

Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

Given the tool has nested objects and no output schema, the description is too sparse. It does not explain the return format, error handling, or the full scope of which sender IDs can be approved/rejected. Admin requirements are mentioned but not expanded.

Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

The schema already describes most parameters (type, senderids) with good coverage (67%). The description adds value by specifying that type must be 6 and that X-API-VASKEY is required, which ties into the headers parameter. This additional context enhances understanding.

Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

Does the description clearly state what the tool does and how it differs from similar tools?

The description clearly states the verb 'Approve or reject' and the resource 'Sender IDs', and notes it's for admin use. This distinguishes it from sibling tools like 'create_sender_id' and 'list_sender_ids'. However, the endpoint path 'sms/status' could cause confusion as it doesn't match the tool name.

Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

Does the description explain when to use this tool, when not to, or what alternatives exist?

The description implies usage for approving/rejecting sender IDs and requires admin privileges. It does not explicitly state when not to use this tool or provide alternative suggestions, leaving usage context somewhat vague.

Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.
