get_menu_item_options

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

Annotations already declare readOnly, idempotent, non-destructive, openWorld, so the safety profile is covered. The description adds useful scope info (single item, one level of nesting) but doesn't note rate limits, caching, or freshness of price data. Adequate but not rich.

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?

One tight sentence, front-loaded with the verb and immediately enumerating return content. Every phrase earns its place with no filler.

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?

Covers what the tool returns, which is helpful given no output schema, but omits parameter meaning and any usage context. For a 3-param read tool with zero schema descriptions, more is expected.

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?

Schema description coverage is 0% – only patterns and an enum are documented structurally, not the meaning of store_id/item_id/fulfillment_type. The description says nothing about parameters, so the agent gets no semantic help for any of the three. Below the baseline because no parameter info appears at all in the description.

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?

Clear verb (read) and resource (menu item options) with an explicit enumeration of what's returned: price, customization groups, min/max constraints, one nested options level. Distinguished from get_restaurant_menu by focusing on a single item's options rather than the whole menu.

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?

No guidance on when to use this versus get_restaurant_menu or when to prefer it over browsing the menu. An agent must infer that it should call this after picking a specific item. No prerequisites (e.g., store/item must exist first) are stated.

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