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

The description adds little beyond annotations. Annotations indicate non-read-only and non-destructive, but the description does not clarify whether areas are added incrementally or replace existing ones. The dryRun and idempotencyKey parameters are defined in the schema but not explained in the description, reducing 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 a single concise sentence with no wasted words. It is front-loaded with the sandbox indicator. However, it could include more detail without becoming verbose.

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 tool with 4 parameters, no output schema, and a sandbox context, the description is incomplete. It does not explain the behavior (e.g., whether areas are appended or replaced), the expected format of areas (references an external file), or any return value. Annotations and schema partially compensate, but the description leaves significant gaps.

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%, so the baseline is 3. The description does not add meaning beyond what the schema provides; it merely states the tool's purpose without elaborating on parameter usage or constraints.

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 tool loads delivery areas for a tariff in a sandbox environment. The verb 'загружает' (loads) and resource 'области доставки для тарифа' (delivery areas for tariff) are specific. It distinguishes from sibling tools like delivery_add_sorting_center or delivery_add_terminals_sandbox by focusing on areas.

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?

No guidance is provided on when to use this tool versus alternatives such as delivery_add_tariff_sandbox_v2 or delivery_add_terminals_sandbox. No conditions, prerequisites, or exclusions are mentioned.

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