TDQS

A4.8/5.0

Behavior5/5

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

Annotations only declare readOnly and openWorld; the description adds real behavioral constraints: pagination must echo the complete next_page_token verbatim, returned note_url must be preserved with xsec_token query params, and the tool deliberately rejects max_items. These are the kind of latent failure modes an agent would otherwise get wrong.

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?

Front-loaded with the core purpose, then alternatives, then pitfalls; every sentence is actionable. The pagination/URL-preservation warnings are stated at length and partially duplicate the page_token schema description, which costs some tightness.

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

Completeness5/5

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

An output schema exists, so return values need not be explained, and the description still covers the highest-risk output handling (note_url preservation). For a 5-parameter read-only search with full schema coverage, nothing an agent needs in order to call it correctly is missing.

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?

Schema coverage is 100%, so baseline would be 3, but the description adds value the schema cannot: it corrects the parameter name (publish_time_range, not publish_time), warns that max_items is not accepted, and reinforces the token-passing contract. It does not cover sort_type beyond what the enum already documents.

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

Purpose5/5

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

States a specific verb and resource ('search Xiaohongshu notes') plus the covered scope (regular, image, video notes), and explicitly names siblings it is not (xhs_search_images, detail tools, comment tools). An agent can distinguish it from every other search tool in the sibling list without opening a schema.

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

Usage Guidelines5/5

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

Gives explicit routing rules: use xhs_search_images for a single image, detail tools when a note_url/note_id is already known, URL/ID tools for comments/replies/speech-to-text. It also states concrete when-to-use conditions for note_type values (image for 图文, video for 视频).

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