Annotations already declare readOnlyHint, idempotentHint, openWorldHint and destructiveHint=false, covering the safety profile. The description adds only that results preserve full fields and paging metadata, which is light return-format context rather than rich behavioral disclosure; with annotations carrying the safety burden a 3 is appropriate.
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?
A single front-loaded sentence with no filler. It is efficient, though its brevity is partly the reason other dimensions are thin.
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?
An output schema exists, so return values need not be spelled out. For a search tool with two undocumented parameters, however, the description is minimal – it omits search behavior, filtering scope, and how results relate to get_user_info.
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% for both parameters. The description's mention of 'paging metadata' faintly gestures at the page parameter but gives no syntax, defaults, or limits, and says nothing about the query parameter's semantics or matching behavior, so it does not compensate for the coverage gap.
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 names a specific verb and resource ('Искать пользователей Kwork' / search Kwork users), so the basic purpose is clear. However, it does not differentiate from the sibling get_user_info, which also concerns users, leaving the agent to infer the boundary between searching and fetching a specific user.
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?
There is no when-to-use or when-not-to-use guidance, and no mention of alternatives such as get_user_info. The agent gets a purpose statement but no routing context for choosing this tool over its siblings.
Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.
