Create Wiki Grid

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

Annotations include openWorldHint=false and destructiveHint=false but no readOnlyHint, so the description's added statement 'This changes structured data' provides a useful mutation warning. However, it does not elaborate on permissions, whether the operation is reversible, or how it affects the host page, leaving only partial behavioral transparency.

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 extremely concise: two short sentences, front-loaded with the action and resource. The second sentence adds a behavioral warning without redundancy, making every word useful.

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?

Given the output schema exists and the parameter schema is fully described, the description does not need to restate those details. However, for a creation tool, it is thin on context such as page requirements ('on a page' is vague), how page_id/slug selection works, or what the resulting grid looks like. It is adequate but not complete.

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?

All three parameters (slug, title, page_id) already have descriptive text in the input schema, giving 100% schema coverage. The description adds no parameter-level meaning beyond what the schema provides, so the baseline score of 3 is 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 states a specific action ('Create') and a specific resource ('a Yandex Wiki dynamic table resource on a page'), which clearly distinguishes it from sibling tools like grid_update, grid_delete, and grid_get. The title reinforces the same clear intent.

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 phrasing 'Create a Yandex Wiki dynamic table resource' implies the tool is for creating a new grid, but it does not explicitly say when to prefer this over alternatives such as grid_add_rows or grid_update. It also does not mention prerequisites like the need for an existing page.

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