task_checklist

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

The annotations already provide readOnlyHint=true and openWorldHint=true, so the safety profile is covered. However, the description adds no behavioral context beyond a label; it does not mention scoping, limitations, or any behavior not already captured by annotations. No contradiction exists, but there is no added 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 definition is extremely short with zero redundancy, making it structurally efficient. However, the brevity borders on under-specification rather than crafted conciseness, so it does not earn a 5.

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 one parameter, full schema coverage, an existing output schema, and readOnly/openWorld annotations, the terse description is nearly adequate. Still, it lacks an explicit verb or statement of operation, leaving an agent to infer that this tool retrieves task checklist items.

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 single parameter 'id' has full schema description coverage (100%), including 'ID задачи' (task ID). The tool description adds no additional semantic detail about the parameter, so the baseline 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 'Пункты чек-листа задачи' ('Task checklist items') is a noun phrase that essentially restates the tool name 'task_checklist' rather than stating a specific action. It does not clearly say whether the tool lists, retrieves, or manages checklist items, and it fails to differentiate from siblings like task_checklist_add or task_checklist_complete.

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 about when to use this tool versus alternatives such as task_checklist_add or task_checklist_complete. The only implied context is the required 'id' parameter, but the description itself provides no usage direction.

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