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

The annotations already declare readOnlyHint=true and openWorldHint=false, so the safety profile is covered. The description adds that the response includes a price and a free re-download indicator — useful, since there is no output schema — but the fragment '무료. [무료]' adds no information and muddies an otherwise billing-relevant disclosure.

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?

One substantive sentence is followed by '무료. [무료]', a duplicated dangling fragment that consumes attention without adding meaning. The useful information is front-loaded, but the trailing noise is real waste in a two-sentence description.

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?

With no output schema and a billing-related purpose, the description should say more about the return shape (currency, or what the price field represents) and about whether calling this incurs any cost. It covers the headline purpose but leaves the practical answer shape underspecified.

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 100% and both document_id and version are documented in the schema, so the baseline of 3 applies. The description adds nothing about what 'version' means in a pricing context (for example, whether re-quoting a previously downloaded version is the free case).

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 first sentence names a specific action and object: it checks the price of a DOCX download of the current content plus free re-download eligibility. That is more than a restatement of the name, but it never distinguishes itself from the sibling document_download (which performs the actual download) or from tts_quote, the other quoting tool.

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 statement of when to call this versus document_download, and no prerequisite or ordering guidance (for example, 'call before downloading to obtain a price'). The implied workflow must be inferred entirely by the agent.

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