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 adds almost nothing beyond that: it does not explain what a 'rolling summary' contains, how fresh it is, or that it requires an externally supplied Cricinfo URL. With an output schema present, return-shape detail is not required, but the content hint is too thin to count as added behavioral context.

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?

One short sentence with no padding, so nothing is wasted, but the sentence is too sparse to earn its place as the tool's only guidance. Front-loading is fine; the problem is under-specification rather than verbosity.

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 single-parameter, URL-driven read tool with an output schema, the description should at minimum say what the URL points to and where to obtain it. Neither is present, and no light is shed on what 'rolling summary' covers, leaving a gap the structured fields do not fill.

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% for the single required 'url' parameter, so the schema gives the agent nothing beyond the name and type. The description does not compensate: it never states that the value must be a Cricinfo team URL, nor where such a URL comes from (e.g., cricinfo_teams).

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 phrase 'Cricinfo team profile and rolling summary' names the resource (a team profile) and hints at content (a rolling summary), but there is no verb and no differentiation from siblings like cricinfo_teams, cricinfo_squads, or cricinfo_team_schedule. An agent cannot tell from the text alone why it would pick this over the teams list.

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 guidance, no prerequisite, and no mention of an alternative. With siblings such as cricinfo_teams and cricinfo_squads in the same family, the absence of any routing hint leaves selection entirely to inference.

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