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

Annotations already declare readOnlyHint=true and openWorldHint=true, so safety and network scope are covered. The phrase 'selectable entities' adds some useful context that this is a catalog/discovery endpoint rather than a data payload, but nothing is said about caching, pagination, or how the entities relate to downstream tools.

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 sentence with no padding, front-loaded with the resource name. It is efficient, though arguably under-specified rather than truly concise.

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 there are no parameters to document. Still, for a catalog tool whose entire value is telling an agent what it can select and for what, the description omits how the entities connect to sibling tools like cricinfo_records.

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?

The tool takes zero parameters and the schema coverage is 100%, so there is nothing for the description to compensate for. Baseline 4 applies: no parameter semantics are needed.

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 the resource ('Cricinfo records catalog') and characterizes it as holding 'selectable entities', which implies a discovery/index role. However, it never states a clear verb or what an agent actually gets back, and it does not distinguish itself from the sibling cricinfo_records tool, which likely holds the actual record data.

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 guidance is provided. It does not say whether this should be called before cricinfo_records, whether the entities are inputs to another tool, or when an agent should skip it. The word 'selectable' hints at a lookup-first flow but leaves the routing to inference.

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