vk_groups_get_callback_confirmation_code

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

No annotations are provided, so the description carries the full burden. It states 'Access level: read' and 'Returns...' which implies a safe, read-only operation. However, it lacks details on rate limits, prerequisites, or response format. The description is adequate but not rich.

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 concise at two sentences, but includes redundant tags (tool name, VK method) that are evident from context. It is front-loaded with the key action. Could be slightly tighter, but overall efficient.

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 one parameter and no output schema, the description is complete enough. It states the purpose, access level, and references the official API method. It does not explain return value structure, but for a simple confirmation code, the description suffices.

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?

There is one parameter (group_id), and the schema covers it 100% with a description. The tool description adds no extra parameter information beyond the schema, meeting the baseline expectation for a simple parameter.

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 tool returns the Callback API confirmation code for a community. It explicitly distinguishes from sibling tools like vk_groups_get_callback_servers and vk_groups_get_callback_settings by specifying the unique output. The reference to the VK API method further clarifies its purpose.

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 does not provide explicit guidance on when to use this tool versus alternatives. It implies usage when needing a confirmation code, but no exclusions or context are given. Among many sibling tools, this is a gap.

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