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

Annotations already declare readOnlyHint=true, idempotentHint=true, destructiveHint=false, and openWorldHint=false, so the safety profile is covered. The description adds useful context about linked golfers and returned fields, but it does not explain how the limit parameter affects result behavior or pagination.

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 front-loaded sentence with no filler. It efficiently combines the usage trigger and the returned data categories.

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?

The description covers purpose and returned fields, and annotations cover safety for this simple read-only tool. However, with no output schema and no parameter description coverage, the missing explanation of 'limit' leaves a meaningful gap in how to control result size.

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 single optional parameter 'limit' has 0% schema description coverage and is not mentioned in the description at all. The description's word 'recent' loosely implies a bounded result set, but it does not explain the default of 5, maximum of 20, or what the limit controls.

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 use case and resource: linked golfer asking about golf rounds or handicap. It also enumerates returned fields like course, holes, strokes, to par, putts, and handicap, though it does not explicitly contrast with sibling tools such as recent_sessions or progress.

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?

Gives a clear trigger: use when a linked golfer asks about their rounds or handicap. It does not name alternatives or exclusions, but the context is sufficient for an agent to know when this tool applies.

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