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

Annotations already declare readOnlyHint=true and destructiveHint=false, and the description merely restates this as "Read-only", which adds no new information. It omits useful behavior such as ordering, default limit, or how many results are returned, and the disclaimer sentence is a compliance note rather than behavioral disclosure.

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?

Three short sentences with the core purpose front-loaded and no padding. The middle disclaimer sentence is the only marginally expendable element.

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 no output schema, the description does well to indicate the return content (hit/miss outcomes), but it leaves default paging, ordering, and result volume unspecified for a list tool. Adequate but with clear 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?

Schema description coverage is 50%: the sport enum has a clarifying note while limit (1-30) is undocumented. The description adds no parameter meaning at all, so it fails to compensate for the coverage gap as required for a low-coverage schema.

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 and resource: returns recently settled tip outcomes (hit/miss). The parenthetical clarifies the return content, which is genuinely differentiating. It does not explicitly contrast with siblings like list_today_tips, 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?

"For track-record questions" implies a use case but gives no explicit when-to-use versus list_today_tips or get_match_tip, and no exclusions. Usage context is only implied.

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