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

Annotations already declare readOnlyHint=true and openWorldHint=true, so the safety profile is covered. The description usefully narrows the target to 'the public match page' and states the content mix (ball-by-ball plus pre-commentary), but says nothing about pagination, freshness/live-update behavior, or the limit parameter's effect on results.

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, front-loaded sentence with no filler. It is efficient, though at this length it leaves no room for the usage and parameter detail the schema coverage gap demands.

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 values need not be explained, and annotations cover the safety profile. However, for a tool with 0% parameter documentation and a required URL whose source is unspecified, the description is thin on how to construct a valid call.

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%, so the description must carry the burden for both parameters. It partially compensates for 'url' by implying it is a public match page URL, but gives no format guidance, and the 'limit' parameter is not mentioned at all.

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 a specific verb ('Returns') and a precise resource ('latest ball-by-ball entries and editorial pre-commentary embedded in the public match page'), which cleanly separates it from generic siblings like cricinfo_match or cricinfo_scores. It stops short of explicitly naming a sibling to differentiate against, but the resource scope is unmistakable.

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 when-to-use or when-not-to-use guidance. It does not say how to obtain the required match-page URL, whether the match must be live, or how this differs from cricinfo_match/cricinfo_scores when an agent wants match content. Usage is only implied by the resource name.

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