TDQS

B3.3/5.0

Behavior3/5

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

Annotations already declare readOnlyHint, idempotentHint, destructiveHint=false and openWorldHint, so the safety profile is covered. The description adds only 'via pinned API client' (a version/consistency note) and 'full standard' (completeness), which is modest extra context. It does not mention rate limits, caching, or payload size.

Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

Conciseness4/5

Is the description appropriately sized, front-loaded, and free of redundancy?

A single front-loaded sentence that states the action and the payload. The trailing 'через pinned API client' is slightly incidental but does carry a consistency guarantee, so little is wasted.

Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

Completeness3/5

Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

An output schema exists, so return-value explanation is not required, and the empty parameter set means there is little else to document. However, the description never says what 'exchangeInfo' contains or when an agent should call it, which is a gap for a zero-arg, open-world metadata tool.

Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

Parameters4/5

Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

The tool takes zero parameters, so there is nothing for the description to disambiguate and the baseline of 4 applies. Schema description coverage is 100% and the object is empty with additionalProperties false, leaving no parameter ambiguity.

Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

Purpose4/5

Does the description clearly state what the tool does and how it differs from similar tools?

States a clear verb ('Получить') and resource ('полный стандартный exchangeInfo response'), so an agent knows it fetches the full exchange metadata payload. The term 'exchangeInfo' is domain jargon borrowed from the underlying API, but the Kwork title corroborates the resource. No sibling overlaps with exchange metadata, so differentiation is implicit rather than stated.

Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

Usage Guidelines2/5

Does the description explain when to use this tool, when not to, or what alternatives exist?

The description gives no when-to-use or when-not-to-use guidance, no indication of freshness/caching semantics, and no mention of how it relates to other tools. An agent must infer from the name alone that this is the metadata source for ticker/symbol data.

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