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

Annotations already declare readOnlyHint=true, idempotentHint=true and destructiveHint=false, so the safety profile is covered. The description adds the useful disclosure that results carry source and official website URLs, but says nothing about pagination behavior despite page/page_size parameters.

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?

Three short sentences, front-loaded with the core action and match semantics, with no filler. It stays tight even though it omits needed detail.

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 no output schema, the description usefully sketches the return shape (source and official website URLs), which is a real contribution. However, for a paginated search tool it omits how results are paged or ordered, leaving a meaningful gap.

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% across 4 parameters, so the description must compensate. It loosely maps 'keyword' to query and mentions category, but leaves page and page_size (including the default of 10 and the max of 20) completely unexplained, so an agent cannot infer result-windowing behavior.

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 and resource ('Search published AI tools') and clarifies the match surface (name, description, tags), which tells an agent what a keyword hit means. It does not differentiate from get_tool, the sibling that presumably fetches a single tool, so it stops short of a 5.

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 one actionable routing hint — 'Use list_categories for valid category values' — but never says when to prefer this over get_tool or when not to use filtering. Usage is implied by the description rather than stated.

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