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 usefully discloses the content scope (squad announcements plus series metadata and roster) but says nothing about auth, freshness, or pagination behavior beyond what annotations provide.

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 tight sentence that front-loads the verb and resource with no filler. Efficient, though slightly dense in its trailing enumeration of payload fields.

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. However, for a tool whose only input is a 0%-documented url, the description should clarify what URL is expected; the hint about a 'team profile' only partially closes that gap.

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% for the single 'url' parameter. The description implicitly tells the agent the url refers to a 'selected team profile', which is real value beyond the bare string type, but it does not specify the URL format or where to obtain it.

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?

States a specific verb ('Returns') and resource ('recent squad announcements'), and enumerates the payload (series metadata and player roster). It does not explicitly distinguish itself from siblings like cricinfo_team or cricinfo_series, so it stops short of a 5.

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?

The phrase 'selected team profile' implies the tool operates on a team page, but there is no explicit when-to-use guidance, no prerequisites, and no routing to alternatives such as cricinfo_team or cricinfo_series. An agent gets context but no decision rule.

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