generate_cart_link

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

No annotations are provided, so the description must carry the behavioral disclosure burden. It explains the outcome (the user can open the link and go directly to checkout) but does not disclose potential side effects, authentication requirements, link expiration, or handling of invalid products. It adds some context beyond the bare function but lacks important behavioral details.

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 two sentences, front-loaded with the primary action and then adding the purpose. Every sentence adds value with no redundant wording. It is concise and well-structured.

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 simple one-parameter tool without an output schema, the description adequately explains the purpose and the expected user-facing outcome (link to checkout). It implies the return is a shareable link. However, it does not specify the exact response format or error behavior, and with no annotations, a bit more detail would have been useful. Still, the coverage is reasonably complete for the tool's complexity.

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 description coverage is 100%, so the parameter 'items' and its nested properties are fully documented. The description only loosely refers to 'pre-selected products' but adds no detail beyond the schema. Baseline 3 is appropriate when the schema handles parameter semantics.

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 the tool's function: 'Generate a shareable link to The Bag Kenya with pre-selected products.' It uses a specific verb ('generate') and distinguishes itself from all sibling tools, which focus on browsing, searching, and product info. No other sibling creates a cart link.

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 a clear use case: 'This is the best way to help someone buy items.' This indicates when to use the tool, though it does not explicitly mention alternatives or when not to use it. Since no sibling tool fulfills this function, the implied guidance is adequate.

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