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

Annotations already declare readOnlyHint=true and openWorldHint=false, so safety and scope are largely covered. The description adds that the search is confined to the AgentReady Tools catalog, which is useful context beyond annotations, but says nothing about result caps, ranking, or pagination 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?

A single front-loaded sentence with no wasted words. It is efficient, though the extreme brevity leaves little room for the usage and return-shape context an agent would benefit from.

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 well-documented parameters and annotations covering the read-only profile, the definition is minimally sufficient. However, there is no output schema, so the description should indicate what a search returns (tool entries matching on name, description, slug, or category) or how many; that gap keeps it at adequate rather than complete.

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 both parameters are fully documented in the schema. The description's 'keyword and optional category' only paraphrases those fields and adds no syntax, matching behavior, or format detail beyond them, making the baseline 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 ('Search') and resource ('the AgentReady Tools catalog') plus the matching basis (keyword, optional category). It is clearly a query tool, distinguishable in spirit from get_tool and list_categories, but it never names those siblings or explains the boundary explicitly.

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?

Usage is only implied: an agent can infer this is for discovery across the catalog versus fetching one tool or enumerating categories. There is no explicit when-to-use statement, no when-not-to-use, and no routing to get_tool or list_categories.

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