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 nothing further: no note on pagination, coverage (all matches vs. upcoming), or the format of the required URL, so it contributes little 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, front-loaded sentence with no padding, which is structurally clean. However it is under-specified rather than genuinely concise, leaving the core requirement unstated.

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 described, and the read-only annotation covers safety. The critical gap is the undocumented required 'url' input, which is the only thing an agent needs to supply correctly and is nowhere explained.

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 0% and the sole required parameter 'url' is a bare string with no description. The description mentions 'venue' but never explains that a Cricinfo venue page URL is expected or what such a URL looks like, so it fails to compensate for the coverage 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?

The phrase 'venue fixtures and results' identifies the resource (matches at a venue) but supplies no verb and does not distinguish it from sibling tools like cricinfo_venue, cricinfo_grounds, or cricinfo_team_schedule. An agent can guess it lists matches tied to a venue, but the exact operation (list fixtures/results for a given venue URL) is only inferred.

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 mention of prerequisites, and no reference to alternatives such as cricinfo_venue or cricinfo_scores. The agent is left to 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.
