vk_photos_get_albums_count

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

While 'Access level: read' is stated, no annotations exist, so description should disclose more. It does not explain behavior for missing parameters, whether both IDs can be omitted, or the function of need_system.

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?

Description is short but includes redundant information (VK API method, tool name, section). Could be streamlined without losing clarity.

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?

No output schema, yet description fails to mention return type (likely integer). Lacks details on parameter constraints or behavior, 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 coverage is 67%, so baseline is 3. Description does not add meaning beyond schema; need_system remains undocumented. No additional parameter context provided.

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?

Description clearly states it returns the number of photo albums for a user or community, distinct from other VK photo tools that list albums. The verb 'Returns' and resource 'number of photo albums' are specific and unambiguous.

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 guidance on when to use this tool over alternatives like vk_photos_get_albums, or which parameters to use. Does not specify that user_id and group_id are optional or how they interact.

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