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

Annotations already declare readOnlyHint=true and openWorldHint=true, covering the safety profile. The description adds that no params are needed and names the endpoint path, which is minor added context, but does not disclose return format, caching, or auth requirements.

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 short clauses, but the opening sentence is essentially restated in the second clause ('handicap and strokes-gained overview' appears twice), making it redundant rather than fully front-loaded.

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?

For a zero-param read tool with annotations covering safety, the description is minimally adequate. However, with no output schema present, the description could say more about what the overview returns (format, fields, pagination) to help an agent decide whether to call it.

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?

Zero parameters, so the baseline is 4. The description correctly notes 'no params', confirming the schema's empty object. No parameters exist whose semantics could be clarified further.

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 resource and scope: 'Golf handicap and strokes-gained overview'. The verb is implied rather than explicit, but the resource and domain are clear enough. It is distinguishable from siblings like get_golf_club_stats or get_golf_summary, though it doesn't explicitly contrast with them.

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?

Implies usage by describing the content (handicap and strokes-gained) and noting 'no params', but offers no explicit when-to-use or when-to-prefer-an-alternative guidance despite multiple golf-related siblings like get_golf_club_stats, get_golf_shot_data, and get_golf_summary.

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