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

With no annotations provided, the description carries full burden. It only mentions the output format (list with IDs) but does not disclose behavioral traits such as authentication needs, rate limits, caching, or error handling. It also does not explicitly state that the operation is read-only.

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 bilingual, which increases length unnecessarily. It is front-loaded with Italian then English, making it redundant. The content is adequate but could be more concise by using only one language.

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 search tool with 4 parameters and no output schema, the description gives minimal context: it lists sites and output ID format. It lacks information on error scenarios, pagination, ordering, or how to interpret results. The connection to 'fetch' is mentioned but not explained.

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% with each parameter having a description. The tool description adds minimal value beyond confirming the sites and output ID structure. It does not elaborate on parameter behavior or constraints beyond what the schema provides.

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 it searches articles/operational notes from two specific websites and returns results with IDs for use with 'fetch'. It's specific about the resource and verb. However, it does not explicitly differentiate from sibling tools like 'capabilities' or 'match_use_case', leaving room for ambiguity.

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 a usage pattern (search then pass ID to fetch), but does not provide explicit when-to-use or alternatives. No exclusions or guidance on when not to use this tool compared to siblings.

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