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

Annotations already declare readOnlyHint, idempotentHint, and destructiveHint, so safety is covered. The description adds value by disclosing that results come from public catalog data and include source links and credits, but it does not explain pagination behavior, result shape, or any other runtime traits.

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?

Two concise, front-loaded sentences with no filler. The scope ('Search published flour facts') is stated first, followed by the useful return-behavior line about public data, source links, and credits.

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 low-complexity search tool with no required parameters, the schema covers inputs and annotations cover safety. The description covers the return value at a high level, which is important because there is no output schema. A small gap remains: the exact structure of the catalog results is not described.

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 three parameters (q, limit, offset) are already fully documented in the input schema. The description does not add new parameter-level meaning beyond what the schema provides, so baseline 3 is 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?

The description clearly states a specific verb and resource: search published flour facts. It also distinguishes itself from siblings by noting it returns 'public catalog data with source links and credits,' which separates it from get_flour and the other search tools.

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 is given on when to use this tool versus alternatives like get_flour, search_ingredients, or search_pizzas. The word 'Search' implies usage, but there is no explicit when/when-not or reference to a sibling that fetches a single flour.

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