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

Annotations already declare readOnlyHint, idempotentHint, destructiveHint=false, and openWorldHint=false, covering the safety profile. The description adds useful behavioral context: the menu is official and stored, includes SAR prices and nearest branch, and includes an explicit anti-hallucination instruction. It still lacks freshness, pagination, and auth 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 front-loaded with the core action and result, then adds examples and a useful constraint. The bilingual duplication is somewhat redundant but not excessive, and every part contributes to understanding or safety.

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?

There is no output schema, so the description must describe return values, which it does reasonably: items, categories, SAR prices, and nearest branch page. Parameters are fully covered by the schema, and annotations cover safety. Minor gaps remain around pagination behavior and whether results are cached or live.

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 100%, so all four parameters are already documented in the schema. The description does not add parameter-level syntax or behavior beyond what the schema provides, making the baseline score of 3 appropriate.

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?

States a specific verb (get) and resource (restaurant brand's stored official menu) with scope details: items, categories, SAR prices, and nearest branch page. However, it does not explicitly differentiate itself from siblings like search_restaurants or compare_prices, so sibling disambiguation is left to inference.

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 implies the tool is for retrieving a menu and an ordering branch, but gives no when-to-use guidance, no prerequisites, and no alternatives such as search_restaurants for discovery or compare_prices for price comparison. The only guidance is a negative instruction not to invent items.

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