session_click

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

No annotations are provided, so the description carries the transparency burden. It discloses the return behavior ('Возвращает текст ПОСЛЕ клика') and the session_start requirement, but does not cover side effects, waiting behavior, or failure modes. It is adequate but not rich.

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 compact, front-loaded with the main action, and every clause adds value: target methods, return behavior, and prerequisite. No wasted words.

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 simple click tool, the description covers the core essentials: what to click, how to specify the target, what is returned, and the session prerequisite. An output schema exists, so return-value details are not required in the text. It could be stronger with explicit alternatives to browser_click, but remains sufficient.

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 coverage is 0%, so the description must compensate. It meaningfully explains selector with a concrete CSS example and clarifies target_text as link text. However, max_chars is not mentioned in the description, though its title and default provide some inherent meaning.

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 clearly states the action: 'Клик на живой странице сессии' (click on a live session page), specifies two targeting modes (CSS selector or link text), and notes it returns text after the click. This separates it from generic browser tools like browser_click by anchoring it to the session context.

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 a clear prerequisite ('Требует session_start') and explains how to choose between selector and target_text. It does not explicitly name alternatives or exclusions, but the session-specific framing and requirement provide enough contextual guidance.

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