sis_statuses

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

No annotations are supplied, so the description carries the full disclosure burden. It does not state that the call is read-only, whether results are cached or live, whether an empty response signals 'nothing pending', or what the payload looks like — all critical for a zero-parameter status tool whose main risk is misinterpretation of the result.

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?

A single short sentence with no filler, and the subject matter is front-loaded. The slash-delimited list is telegraphic and slightly hard to parse, but nothing is wasted.

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?

With no output schema and no annotations, the description is the only source of information about what comes back, and it says nothing about return shape or semantics. For a status-aggregation tool, the agent is left unable to interpret the response or know whether the three topics are returned together.

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?

The tool takes no parameters, so there is nothing for the description to disambiguate. The baseline for a zero-parameter schema applies, with no deduction warranted.

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 names a verb (取/fetch) and lists three subject areas: leaving-school check, student-source confirmation, and work-hour declaration. However, 'status hints' (状态提示) never says what a hint actually is, so the scope overlaps ambiguously with siblings such as sis_evals_pending and sis_other_applications, and no sibling is distinguished.

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?

There is no guidance on when to call this tool instead of the many adjacent status tools (sis_evals_pending, sis_registration, sis_other_applications, portal_cards). No triggers, prerequisites, or exclusions are given; the agent must guess from the three nouns.

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