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

No annotations are provided, so the description carries the full behavioral burden. It hints at the data returned but says nothing about read-only safety, authentication/team identifier requirements, or result scope, leaving real gaps for a tool with zero annotation coverage.

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?

One compact sentence lists the payload contents with no filler, and the most identifying content (results, fixtures) comes first. It is a fragment rather than a structured sentence, but nothing is wasted.

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 helpfully enumerates what comes back, which covers the return-value gap. However, for a required-parameter tool with no annotations and 0% schema coverage, the omission of parameter format and usage context leaves it only adequate.

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 0% and the single 'team' parameter is undocumented. The phrase "a club's" weakly implies the argument is a club, but the description never states whether it expects a name, abbreviation, or FPL team ID, so it does not compensate for the coverage gap.

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 names a specific resource and enumerates the concrete content returned (results, goals for/against, clean sheets, fixtures, top players), which separates it from siblings like get_fixtures or compare_players. It lacks an explicit verb and is a noun fragment, so it is clear but not maximally sharp.

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?

There is no when-to-use guidance and no alternatives named. An agent cannot tell from the text whether to call this instead of get_fixtures for a club, or how it relates to get_my_team.

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