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

The annotations declare readOnlyHint=false, destructiveHint=false and openWorldHint=false, so the agent already knows this is a non-destructive, closed-domain operation. The description adds only 'RETURNS: 逐条回复草稿', which usefully discloses the output artifact given there is no output schema, but says nothing about how the draft is produced, whether it invents citations, or what it does with unaddressed comments.

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 pipe-delimited structure front-loads purpose, then WHEN, then ALIASES, then RETURNS, with no filler sentences. The alias list is long but serves retrieval matching rather than padding.

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?

This is a two-parameter generation tool with no output schema, and the definition covers purpose, trigger condition, and the nature of the returned artifact. There is no nested structure, enum, or destructive behavior that requires further disclosure for an agent to call it correctly.

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 parameters carry descriptions (原文, 审稿意见), so the schema already carries the load. The tool description adds no meaning about input format, expected length, or how the two inputs are combined, which is the correct baseline-3 case when the schema is fully documented.

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 title and first clause state a specific verb+resource: drafting point-by-point responses to reviewer comments. An agent can distinguish this from nearby siblings such as deep_peer_review (evaluation) or cover_letter (submission letter) based on the stated output. It stops short of naming a sibling explicitly, so 4 rather than 5.

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 'USE WHEN: the user has reviewer comments and needs point-by-point replies' clause gives a clear triggering condition with both the input situation and the desired artifact. There are no explicit exclusions or alternative-tool routing, which keeps it below 5.

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