get_overview

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

Annotations declare readOnlyHint=true and destructiveHint=false, indicating a safe read operation. However, the description adds no behavioral context: it neither explains what an 'overview' entails nor reveals what the return value contains. It relies entirely on annotations and the tool name, providing no extra information about expected behavior.

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 short phrase, 'Обзор API СамОтправил', which is concise with no filler. However, it is little more than a restatement of the tool name and lacks any informational substance. While it is brief, the brevity sacrifices clarity, making it only partially successful in earning its place.

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?

There is no output schema, so the description carries the burden of explaining what the tool returns. It simply says 'overview' without detailing whether the agent will receive a list of endpoints, a prose summary, or metadata. Given the tool is likely simple, the description is still incomplete because it does not clarify the content or format of the result, nor its role in conjunction with the many sibling tools.

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 has zero parameters, so the baseline score is 4. The description does not need to elaborate on parameter meanings because there are none. The input schema confirms an empty properties object, and the description adds no parameter-related semantics, which is acceptable given the absence of parameters.

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 'Обзор API СамОтправил' translates to 'Overview of the SamOtpravil API'. It names the resource (API) and a generic action (overview), but does not specify what the overview contains or how it differs from sibling tools like list_endpoints or get_endpoint. The purpose is somewhat clear but lacks the specificity needed to distinguish it from other API-related tools.

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?

The description gives no guidance on when to use this tool versus alternatives. It does not mention any prerequisites, intended use cases, or exclusions. With over 60 sibling tools, the lack of usage guidance leaves the agent uncertain about when get_overview is the appropriate choice compared to list_endpoints or get_endpoint.

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