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

Annotations already declare readOnlyHint=true and openWorldHint=false, so the safety profile is covered and the bar is lower. The description adds that results are scoped to specific platform builds (Apple Silicon, Intel, Windows), which is useful content disclosure, but says nothing about freshness, caching, or whether a version number accompanies the links.

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 well-formed sentence with the resource and platform scope front-loaded and no filler. It could have been split to add usage guidance, but nothing present is wasted.

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 simple read-only lookup with one optional enum parameter and no output schema, the definition is close to sufficient. It still leaves the return shape ambiguous — whether the response is a version string, a list of URLs, or both — which an agent needs to know to present results.

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% and the single 'language' parameter is documented with its enum and French default, so the schema carries the meaning. The description adds nothing about the parameter, which is acceptable at full coverage but leaves it at baseline.

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 names the resource (Ricuicui version) and the payload (download pages for Mac Apple Silicon, Intel, and Windows), so the agent knows exactly what comes back. It is clear enough to separate this from my_account and read_documentation, though the verb is implied rather than stated.

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?

There is no guidance on when to call this versus the sibling tools, and no mention of prerequisites or typical phrasing of a user request that should trigger it. The agent must infer usage purely from the resource name.

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