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 only the word 'snapshot,' which loosely hints at point-in-time data but does not explain freshness, pagination, or what the directory contains, so it contributes little beyond the structured fields.

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?

It is a single five-word fragment with no waste, which is structurally clean, but it is under-specified rather than genuinely concise. Brevity here comes at the cost of information an agent needs.

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, but the description still omits the undocumented limit parameter, any usage context, and any distinction from the venue tools. For a directory-listing tool this leaves meaningful gaps.

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 parameter (limit) with 0% schema description coverage, and the description says nothing about it — not its default, maximum, or what happens when it is omitted. With a non-empty schema and zero coverage, the description was required to compensate and does not.

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 'ground directory snapshot' conveys a resource (cricket grounds) and collection semantics (directory/list), which is more than a bare restatement of the name. However, it names no verb, states no scope or filtering behavior, and gives no hint of how it differs from the close sibling cricinfo_venue or cricinfo_venue_matches.

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 prerequisites, and no mention of any alternative. An agent cannot tell from this text whether to call cricinfo_grounds or cricinfo_venue for a given task, so it must guess from names alone.

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