retrieve_vip

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

Annotations already declare readOnlyHint, idempotentHint, openWorldHint and destructiveHint=false, so the safety profile is covered. The description adds the HTTP route and that results are scoped to 'your account', plus that attribute values are returned, but says nothing about error behavior when the IP is unknown or what happens with foreign IPs.

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?

Two short sentences, front-loaded with the identifying verb and resource. The verb phrase is repeated in the endpoint bracket and the trailing sentence ('Get attributes values...') is grammatically awkward, but nothing is bloated.

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?

With no annotations gap and full schema coverage, the main remaining burden is describing the return shape, which the description only vaguely gestures at ('Get attributes values'). It also fails to distinguish this single-item getter from retrieve_vip_list, leaving an agent to infer the split.

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?

Schema description coverage is 100%, with both 'ip' and 'x-trace-id' documented in the schema itself. The description's 'by ip' merely restates the required parameter and adds no format, validation, or addressing semantics beyond what the schema provides - the baseline 3.

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?

States a specific verb and resource ("Get specific VIP by ip"), which is clearer than a bare name and distinguishes it from the list variant by the 'by ip' qualifier. It does not, however, explicitly name retrieve_vip_list as the sibling it is not.

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?

Usage is only implied: 'by ip' suggests it is for fetching a single known VIP rather than enumerating vips. There is no explicit when-to-use, no prerequisite note, and no mention of retrieve_vip_list as the alternative for browsing.

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