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

Annotations declare readOnlyHint=true and openWorldHint=true, so the safety profile is covered. The description adds nothing beyond that: it doesn't state that the input must be a Cricinfo venue URL (not a name or ID), what a 'profile' contains, or any failure mode for unknown URLs.

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 short fragment with zero padding and the resource front-loaded. It is terse to the point of under-specification, but there is no wasted text.

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. Still, for a URL-driven lookup tool sitting among near-identical cricinfo siblings, the definition omits the one thing an agent must know: which URL/identifier to supply and why to choose this over cricinfo_grounds or cricinfo_venue_matches.

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 parameter is a bare 'url' string. The description never explains that this is a Cricinfo venue URL or what form it takes, so the agent must guess the identifier type. With one undocumented param this is a real gap, not a baseline-3 case.

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?

Names the resource (Cricinfo cricket-ground profile), which tells the agent this returns venue information. However, it is a noun phrase with no verb, and it does not distinguish itself from close siblings like cricinfo_grounds (list of grounds?) or cricinfo_venue_matches (matches at a venue). The reader cannot tell whether this is a single-venue lookup or a listing.

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, when-not-to-use, or alternative routing is given, despite three closely related cricinfo venue/ground tools. The agent is left to infer whether to call this, cricinfo_grounds, or cricinfo_venue_matches.

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