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

Annotations only cover safety hints (readOnlyHint=false, destructiveHint=false, idempotentHint=false, openWorldHint=false). The description adds real behavioral context beyond that: the link is temporary, PDF download/saving requires ordinary login, and the PDF is not auto-saved. It stops short of stating link expiry or how long '临时' lasts.

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?

Front-loaded with what is created, then the conditional behavior, then the platform handoff note. Four short sentences, each carrying distinct information, with no filler.

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 2-parameter tool with a nested object, no output schema, and annotations covering only safety, the description supplies the mode logic and the login/PDF caveats an agent needs. Only the lifetime of the 'temporary' link is left unspecified, which is minor.

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%, so baseline is 3, but the description meaningfully adds semantics for `record`: supplying it yields direct result viewing, omitting it routes to the quiz. That is information the schema alone does not convey; `testId` gains nothing beyond its existing description.

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?

States a concrete verb+resource: creating a temporary branded web entry (带16暗影品牌的临时网页入口), and clarifies the two modes it can serve (view a finished result vs. start the quiz). It references score_assessment as the source of the record, linking it into a workflow, but never explicitly contrasts itself with siblings like get_report_pdf or save_completed_result.

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?

Gives an explicit conditional rule: pass the record from score_assessment to open straight into the result view, omit it to enter the quiz, and notes the fixed-Key platform handoff case. This is clear when-to-use guidance, though it does not state when another tool (e.g., get_report_pdf) would be preferable.

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