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

Annotations already declare readOnly, idempotent, non-destructive and closed-world, so the safety profile is settled. The description adds value beyond that by disclosing the return shape (titles, summaries, URLs) in the absence of an output schema, though it says nothing about result ordering or total counts.

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?

Front-loaded with the verb and resource, then the topic list, then the return shape, then the no-query behavior — a sensible order. The topic enumeration ('plating technique, garnishes, sauces, plate types, knife skills...') is long and partly redundant with the schema's example values, but it does convey scope.

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?

With only two optional parameters, no nested objects and rich annotations, the description covers nearly everything an agent needs to call it and interpret results. The notable omission is the default result count of 5, which lives only in the schema.

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 coverage is 100%, so the baseline is 3, but the description adds meaning the schema lacks — that omitting the query returns every guide, which tells the agent the parameter is genuinely optional and what the empty case does. The limit parameter is left entirely to the schema.

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 (find) and resource (plating guides, board guides, holiday hubs, free tools) and enumerates covered topics, which makes it distinguishable from the calculator/recipe siblings. It does not explicitly contrast with search_recipes or get_recipe, so an agent must infer that this searches editorial guides rather than recipes.

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?

Gives clear usage context: use it for topic-based discovery of guides and tools, and it explains the no-query fallback ('lists every guide'), which is a real usage decision point. It names no alternatives or exclusions, so there is nothing steering the agent away from a wrong sibling choice.

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