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

With no annotations, the description carries the full burden, and it does disclose one genuinely useful behavioral fact: that the response includes a data-refresh timestamp, hinting at staleness. However, it says nothing about whether the call is read-only (implied, but not stated), authentication requirements, or caching/refresh cadence.

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 sentence that front-loads the primary value (current/next gameweek) and appends the supporting fields. No filler, no redundancy, nothing to trim.

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?

No output schema exists, so the description must sketch the return shape, and it does so adequately by enumerating the three returned items. For a zero-parameter read-only status tool this is nearly sufficient; only the exact format/types of those fields remain unspecified.

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 tool takes zero parameters, which is the baseline-4 case; there is no parameter syntax or semantics left to explain. The description correctly implies the call needs no arguments.

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 the specific resource and its three components (current/next gameweek, next deadline, last refresh), so an agent can predict the payload. It stops short of a 5 because there is no explicit verb and no direct differentiation from siblings, though the siblings' names are distinct enough that overlap is unlikely.

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 or when-not-to-use guidance, and no sibling is referenced as an alternative. Usage is only inferable from the name and the content list; the description never states the condition under which an agent should call this rather than, say, team_summary or get_my_team.

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