user_pay_forecast_get

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

No annotations are provided, so the description carries the full burden, yet it discloses only the raw endpoint and a category tag. It says nothing about authentication scope (the user_id parameter is documented as an admin acting on behalf of a user, which implies privilege requirements), rate limits, or what a 'forecast' actually returns.

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?

It is short, but that brevity reflects under-specification rather than efficiency: it is a dump of endpoint, tag, and spec metadata with no front-loaded statement of what the tool does for the caller. Nothing here is wasted, but almost nothing useful is present.

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?

With no annotations and no output schema, the description is the only source of behavioral context, and it omits the forecast's return shape, the admin-impersonation implications of user_id, and any usage boundaries. For a payment-forecast endpoint reachable through several sibling tools, this is insufficient.

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 100% and all three parameters (limit, offset, user_id) carry their own Russian descriptions and defaults, so the schema already does the heavy lifting. The description adds no parameter meaning beyond the route, making the baseline 3 appropriate.

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 pairs the HTTP route 'GET /user/pay/forecast' with the Russian label 'Прогноз оплаты' (payment forecast), which conveys a specific resource and read operation. However it does nothing to distinguish itself from close siblings such as user_pay_get, admin_user_pay_get, or user_autopayment_get, so the agent cannot route on purpose alone.

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 prerequisite conditions, and no named alternative. The only implicit hint is the GET verb plus the 'Платежи' tag, which is not enough to tell an agent when this forecast should be preferred over user_pay_get.

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