vk_groups_get_callback_servers

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

No annotations exist, so the description must disclose behavioral traits, but it does not. It fails to mention that this is likely a read-only operation, any required permissions, return format, or side effects. The agent has no behavioral context.

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?

While extremely short, the description is under-specified rather than concise. It front-loads a technical identifier but wastes the opportunity to provide substance. Every sentence should earn its place; this single phrase adds negligible value.

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 no annotations, no output schema, and minimal parameter info, the description is wholly incomplete. An agent cannot determine what the tool returns or how to use it correctly. It fails to compensate for the lack of structured metadata.

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 0%, and the description adds no meaning to parameters. For example, server_ids is not explained (e.g., optional filter to get specific servers). The agent cannot infer parameter purpose from this description.

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 'groups.getCallbackServers' is a tautology, restating the tool name without explaining what the tool does. It does not specify the verb or resource (e.g., 'retrieve callback servers for a group'). This provides minimal help to an AI agent.

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?

No usage guidelines are provided. The description does not indicate when to use this tool versus sibling tools like vk_groups_get_callback_settings or vk_groups_get_callback_confirmation_code. An agent cannot differentiate based on this description.

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