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

No annotations are provided, so the description carries the full disclosure burden, yet it says nothing about scope (all projects vs. filtered), pagination, ordering, or authorization requirements. Only the verb "получить" implies a read-only operation, and an output schema exists to cover the return shape, but the behavioral profile remains largely undisclosed.

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 short sentence with no filler and the resource front-loaded. It is efficiently sized for a zero-parameter tool, though its brevity edges toward under-specification rather than genuine economy.

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-param read tool with an output schema, the description covers the bare essentials of what is returned. It still omits the one thing an agent most needs here — how this differs from the many sibling project-listing tools — leaving a clear gap.

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, so there is nothing for the description to clarify beyond the schema. Baseline 4 applies for a parameterless tool.

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 clear verb and resource ("Получить проекты пользователя" = get the user's projects), which is unambiguous on its own. However, it does not distinguish itself from near-identical siblings such as get_user_project (singular), get_user_project_by_domain, or get_user_keywords_projects, so an agent cannot tell from the text why it should pick this list tool over those.

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 guidance on when to use this versus get_user_project or get_user_project_by_domain, nor any prerequisite or scoping note. The agent must infer from the names alone that this returns the full list of projects.

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