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

No annotations are provided, so the description bears full responsibility. It states the tool returns results with IDs, implying a read-only operation, but omits details like result ordering, pagination, latency, or any side effects. It does not contradict any annotations.

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 extremely concise: two short sentences that cover the purpose, scope, and linkage to a sibling tool. Bilingual but no wasted words. Front-loaded with actionable information.

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?

Given the lack of output schema, the description sufficiently explains that the result list contains IDs for use with 'fetch'. It covers what is searched and how to proceed. Could mention result fields briefly, but acceptable for a search tool.

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?

All parameters are documented in the input schema with descriptions and enums, so the description adds little parameter-level meaning. The mention of returning IDs provides some output context but does not enhance parameter semantics beyond 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?

The description clearly states it searches operational notes from two specific sites (csidia.com and splidia.com) with their domains. It uses a specific verb ('cerca' / 'searches') and resource ('articoli' / 'operational notes'), and explicitly ties results to the sibling tool 'fetch', distinguishing it from other 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?

The description indicates that returned results can be passed to 'fetch', establishing a clear workflow. However, it does not explicitly mention when not to use this tool or provide alternatives beyond fetch.

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