Get Products

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

With no annotations provided, the description bears full responsibility for behavioral disclosure. It mentions optional limit and sort but fails to explain default behavior (e.g., returns all products if no limit), pagination, or any side effects. The description adds limited context beyond the schema.

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?

The description is a single, well-structured sentence that delivers the core purpose immediately. It is appropriately sized with no extraneous words, earning every word's 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?

Given the absence of an output schema and the tool's role as a general catalog fetcher among 27 siblings, the description is incomplete. It lacks details on default behavior, output format, and when to choose this over more specific tools. More context is needed for an agent to use it reliably.

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 schema has 0% description coverage, so the description must compensate. It adds that the sort parameter sorts 'by id', which is not in the schema, and mentions 'limit'. However, it does not explain the limit meaning (number of products) or default values, which weakens the contribution.

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 clearly states it fetches the product catalog from fakestoreapi.com, with optional limit and sort. It uses a specific verb 'Fetches' and resource 'product catalog', making the purpose clear. However, it does not explicitly differentiate from sibling tools like getProductsByCategory or searchProducts.

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 description provides minimal guidance on when to use this tool versus siblings. It does not mention scenarios where alternatives like getProductById or getProductsByCategory would be more appropriate. No when-not-to-use or prerequisites are stated.

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