TDQS

A4.3/5.0

Behavior4/5

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

Annotations already declare readOnlyHint=true and openWorldHint=true, so the safety profile is covered. The description adds a non-obvious data-quality caveat that images and videos come only from search results and may be incomplete, which is behavior an agent cannot infer from annotations. It does not discuss result volume, truncation, or rate limits, keeping it below a 5.

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 action, then routing guidance, then the caveat — a sensible order with no filler sentences. The semicolon-chained single sentence is dense and slightly run-on, which costs a point against a cleaner multi-clause structure.

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

Completeness4/5

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 unnecessary, and the description covers routing plus a media-completeness caveat. For a simple three-parameter read-only search this is nearly complete; only result-count or pagination-end behavior is unaddressed, which is minor.

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

Parameters3/5

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

Schema description coverage is 100%, so keyword, sort_type, and page_token are already fully documented including the 'pass the previous next_page_token back unchanged' rule. The description only restates that pagination tokens and sorting are supported, adding no meaning beyond the schema. Baseline 3 applies.

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 ('按搜索词搜索百度贴吧公开帖子') plus scope (public posts only) and mentions pagination/sorting support. It also names the sibling that covers the adjacent case ('baidu_tieba_search_posts_in_forum'), so an agent can distinguish it from baidu_tieba_search_general, get_post_detail_by_url, and the in-forum search without opening any 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?

Explicitly routes three alternatives: use general search when you need post ordering from aggregate search, use the detail tool for a specific post link, and use baidu_tieba_search_posts_in_forum when a forum must be scoped. The alternatives are named by role rather than exact tool id in two cases, but the mapping to the sibling list is unambiguous.

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