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

Annotations already declare readOnlyHint=true and openWorldHint=true, covering the safety profile. The description adds nothing behavioral beyond that, and its second sentence enumerates response fields, which the existing output schema already carries. No auth, rate-limit, or format-completeness context is provided.

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?

Two short sentences, front-loaded with the purpose, so it reads efficiently. However, the second sentence duplicates output-schema content and consumes space that could have documented the required url parameter.

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?

An output schema exists, so return-value detail is not required from the description, making that sentence redundant. The real gap is the unexplained required url parameter, which is the one thing an agent needs in order to invoke the tool successfully.

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?

There is one required parameter (url) with 0% schema description coverage, and the description never mentions it. For a URL-scraping tool, the agent gets no guidance on what URL form is expected, so the description fails to compensate for the schema gap.

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 resource (ICC rankings) and its source (Cricinfo), which is clear enough for an agent to distinguish it from stats/records/scores siblings. It does not explicitly name any sibling or scope boundary, but the resource itself is unambiguous.

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?

No when-to-use guidance, no alternatives named, and no hint about how it differs from cricinfo_records, cricinfo_stats, or cricinfo_team. The agent must infer usage entirely from the name.

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