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

No annotations are provided, so the description carries the full behavioral burden, and it discloses almost nothing beyond the purpose sentence: no indication of whether this mutates state, requires permissions, or how results are returned. For an unannotated tool the agent is left to assume it is a safe read.

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 short clauses with the purpose front-loaded and the parameter enumeration second; nothing is padded. The value list is dense but useful rather than wasteful.

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-optional-parameter checklist tool, the description supplies the purpose, the trigger moment, and the valid category set, with no output schema needed to explain returns. The remaining gap is the multi-select encoding into a string parameter, which is a minor but real omission.

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 0% and the single 'categories' property has no type-level detail, so the description is the only source of meaning — it names the six allowable values (food, cosmetic, electric, toy, medical, general) and notes multi-select. It does not explain how to encode multiple values into the string type (delimiter, array, etc.), and the empty default (0 required) is unaddressed.

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 specific verb+resource in context: a compliance checklist run before a group-buy listing goes live (開團上架前合規清單). This is clearly distinguishable from sibling calculators and lookup tools. It stops short of explicitly differentiating from check_ad_claims or check_tax_registration, which are also compliance checks.

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?

The phrasing '上架前' (before listing) implies the usage moment — pre-publication compliance review — which is enough to infer when to call it. However, it names no alternatives and gives no explicit when-not guidance relative to the overlapping compliance siblings.

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