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

No annotations are provided, so the description carries the full burden. It usefully discloses that the content is Chinese and is first-hand industry investigation notes from an 'information gap' perspective, which helps interpretation, but it omits behavioral traits such as return size, truncation, or behavior on a missing/ambiguous title.

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?

Two compact sentences with the purpose front-loaded and no padding. The second sentence about content nature earns its place as interpretation context, though slightly ornamental.

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?

For a single-parameter read tool with no output schema and no annotations, the description covers the essentials (what is read, in what language, from what kind of source). It stops short of noting return shape or failure behavior, leaving minor gaps that a reader tool could reasonably fill.

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 description coverage is 100%, so the schema already documents the title parameter fully, including fuzzy matching and the list_articles lookup hint. The description adds no parameter-level syntax or format detail beyond that, making the baseline 3 appropriate.

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 description states a specific verb (读取/read) and resource (研究文章全文/full text of a research article), and the '全文' scope distinguishes it from list_articles, which only surfaces titles. It is clear enough that an agent would not confuse it with the sibling listing tool, though it does not name siblings explicitly.

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?

It gives an implied usage context ('供 Agent 引用分析' – for agent citation/analysis) and the schema hints that list_articles is the way to find titles, but there is no explicit when-to-use/when-not guidance or routing to alternatives among ask_edge, read_signal_board, etc. Usage must be inferred.

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