Create OlaOla Shadow Cart

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

No annotations are provided, so the description bears the full burden. It states that the cookie stays internal to the MCP process and the cart is anonymous, which discloses key behavioral traits. However, it does not mention side effects or idempotency.

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 concise: a single sentence followed by a clause. It is front-loaded with the purpose and immediately provides usage guidance. Every word is necessary.

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 single parameter, no output schema, and no annotations, the description is fairly complete. It covers purpose, usage context, and a behavioral note. It could elaborate on return value or conflicts with existing carts, but is adequate for a creation tool.

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 description does not explain the 'seedUrl' parameter beyond what the schema provides (format: uri). With 0% schema description coverage, the description should compensate but fails to add meaning to the parameter.

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 'Create an anonymous OlaOla planning/simulation cart,' which is a specific verb+resource combination. It distinguishes from sibling tools like olaola_add_to_shadow_cart, olaola_read_shadow_cart, and olaola_add_to_account_cart by emphasizing anonymity and creation.

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 explicitly advises to use only when the user wants a shadow cart or credentials are unavailable, providing clear context. It does not explicitly mention alternatives or when not to use, but the 'only when' phrasing offers sufficient guidance.

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