create_gift

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

Description indicates a write operation (create) but lacks details on side effects, error behavior (e.g., if wishlist_id does not exist), or auth requirements. No annotations are present, so the description carries the full burden but does not fully disclose behavior.

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?

Description is two sentences with no fluff. First sentence states purpose, second lists required and optional parameters. Every word serves a purpose, and the structure is front-loaded for quick scanning.

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?

While the description covers all parameters and basic purpose, it omits success/error response information and does not explain expected outcomes. Given the absence of an output schema and annotations, the description leaves gaps for an agent to infer important operational details.

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?

Description names all 7 parameters and notes that image_urls has a max of 5, adding some context beyond the schema. However, schema coverage is 0% (no property descriptions), and the description does not explain constraints like UUID format for wishlist_id or length limits for name, so added value is marginal.

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?

Description clearly states 'Create a gift inside a wishlist,' specifying the action (create) and resource (gift). It distinguishes from siblings like create_wishlist and update_gift by using the verb 'create' and the noun 'gift,' making it unambiguous.

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?

Description lists required parameters (wishlist_id, name) and optional ones, providing basic usage context. However, it does not explicitly state when to use this tool versus alternatives (e.g., update_gift for modifying existing gifts), so guidance is implied but not comprehensive.

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