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

Annotations already declare readOnlyHint=true and openWorldHint=true, so the safety and reach profile is covered. The description adds only that the content is a public page and includes 'pre-commentary', which is modest behavioral context beyond the structured fields; no rate limits, auth needs, or freshness semantics are mentioned.

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?

Two sentences, zero padding, with the core capability (ball-by-ball + pre-commentary) front-loaded before the disambiguation routing. Every clause earns its place.

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?

With an output schema present, annotations covering safety, and full schema coverage on both params, the description carries only the disambiguation burden it needs to. It is nearly complete, missing only a note on freshness or live-vs-completed match applicability.

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 100%, so both parameters (url and limit) are already documented in the schema. The description restates the input as a 'public cricket match page' but adds no format, canonicalization, or limit semantics beyond what the schema provides, so baseline 3 applies.

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 states a specific verb ('Fetch') and a precise resource ('ball-by-ball entries and editorial pre-commentary') scoped to 'a public cricket match page'. It also names the two sibling tools it must not be confused with, so an agent can distinguish it without opening any schema.

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?

It explicitly routes the agent to alternatives ('Use cricinfo_match for match details or cricinfo_news for cricket stories'), which is clear context for when to pick another tool. It stops short of an explicit positive trigger for this tool (e.g. 'use this when you need live over-by-over text'), leaving that to inference.

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