vk_groups_get_members

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

With no annotations, the description should disclose required permissions, pagination behavior, and other traits. It does not; it only states the basic result. Important details like the need for an access token with group scope or the fact that sorting options depend on user role are omitted.

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 sentence, very concise and front-loaded. No extraneous information, but slightly too minimal given the tool's complexity.

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 6 parameters, no output schema, and no annotations, the description is too brief. It does not explain how to combine parameters (e.g., filter with sort) or what the response format looks like, leaving gaps for an agent.

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%, so the baseline is 3. The description adds no extra meaning beyond the schema; it does not explain parameter usage or provide examples.

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 'Returns a list of community members' uses a specific verb ('returns') and resource ('community members'), clearly distinguishing it from sibling tools like vk_groups_get (which returns groups) and vk_friends_get (which returns friends).

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 explicit guidance on when to use this tool versus alternatives is provided. The context suggests it is for fetching group members, but there is no mention of prerequisites (e.g., authentication) or when to prefer it over other member-related tools like vk_groups_get_invited_users.

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