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

Annotations already declare readOnlyHint=true, idempotentHint=true, destructiveHint=false and openWorldHint=false, so the safety profile is fully covered by structured data. The description contributes one real behavioral fact beyond that — the result is limited to workspaces accessible to the current user — but says nothing about ordering, pagination, or the shape/size of the returned list.

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 sentence with no filler; the resource and its scope are front-loaded. Nothing in it is redundant with the structured fields.

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?

For a zero-parameter read-only list tool with full annotation coverage and no output schema, the description covers what is returned and to whom it is scoped, which is the essential information. It could still note whether the list can be empty or what fields each entry contains, but nothing critical for correct invocation is missing.

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?

The tool takes zero parameters and the schema is empty with additionalProperties=false, so there is nothing for the description to explain. Per the rubric a parameterless tool gets a baseline of 4.

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 states a specific verb ("Возвращает список") and resource ("рабочих пространств (workspaces)"), plus a scope qualifier ("доступных текущему пользователю"). It is clear enough to act on, but it does not name or differentiate itself from adjacent siblings such as get_workspace_details or get_workspace_roles, and the title ("Список аккаунтов") uses different vocabulary (accounts vs. workspaces) that could cause mild confusion.

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 guidance, no prerequisites, and no mention of alternatives such as get_workspace_details for a single workspace. The usage is only inferable from the tool name and the scoping phrase, with nothing explicit in the text.

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