v1.17.16Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
With no annotations, the description carries the whole behavioral burden. It does disclose the return payload shape at a high level ('category tabs with ids') and, by implication, that this is a read. It says nothing about scope, pagination, or completeness of the tab list, but for a zero-parameter read, the risk is low enough that a 3 fits.
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 sentences with no filler. The returned resource is front-loaded and the endpoint chaining hint follows, so every clause earns its place.
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 zero-parameter tool with no output schema, the description carries the explanation of return values and does so in outline ('category tabs with ids'). It does not describe the structure of a tab or whether ids are stable, but an agent has enough to call it and hand the ids downstream.
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?
There are zero parameters, so the baseline is 4 and there is nothing for the description to disambiguate. The only semantic detail needed is the output shape, which it briefly provides.
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 gives a specific verb and resource: it 'Returns the brand channel's category tabs with ids.' That is clearly different from a product search, but it never distinguishes itself from the nearby shein_categories / shein_trending_categories siblings, so an agent must still infer which category tool to open. The noun phrase 'SHEIN brand channel categories' also reads more like a brands list than the category tabs it actually returns.
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 states a concrete downstream use: the returned ids are 'usable with /shein/category/goods and /shein/products/search', which tells the agent this is the id-acquisition step before those calls. There is no explicit 'use this instead of X' exclusion against the other shein category tools, so it stops short of full routing guidance.
Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.
