run_alibaba_product

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

With no annotations, the description carries the full burden. It usefully discloses the output contents and the cost model ('Flat 5 points per successful run'), which is genuine behavioral context. However, it omits auth/permission requirements, rate limits, and error behavior for a paid external-API call.

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 tightly packed sentences with no filler; the core purpose and content list are front-loaded, and the cost note is appended without bloat.

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, the description correctly enumerates the returned fields so the agent knows what it gets back, and it covers the single required input. It is nearly complete for a one-parameter detail tool, missing only usage routing to the search sibling.

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 is a single parameter with 100% schema description coverage, so the baseline is 3. The description restates that the product can be an ID or URL, matching the schema without adding syntax or format detail beyond it.

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 and resource ('Get full Alibaba product details') and enumerates the returned content (price tiers, MOQ, attributes, variants, supplier). The 'by ID or URL' phrasing implicitly distinguishes it from the search sibling, but it never names run_alibaba_product_search, so the differentiation is inferable rather than explicit.

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?

Usage is implied: requiring an ID or URL suggests this is a detail-fetch step that follows a search, but no alternative is named and no when-to-use or when-not-to-use guidance is given. The agent must infer that run_alibaba_product_search is the upstream tool.

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