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

With no annotations, the description carries the full disclosure burden, and it only states the data scope ('back to 2016-17'). It says nothing about read-only nature, behavior for an unknown/ambiguous player, or the granularity of the returned totals.

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 tight sentence with the scope qualifier parenthetical, zero filler, and the key information 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?

There is no output schema, so the description must convey what comes back, and it does at a high level (season-by-season totals linked across seasons). However, it omits the parameter format and the shape/granularity of the returned season records, leaving gaps for a tool whose schema gives no help.

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 'player' parameter has no description. The description never clarifies whether 'player' is a name, an FPL element ID, or something else, so the parameter's actual format is undocumented in both schema and text.

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 the resource (a player's FPL totals) and the precise scope (every season loaded, back to 2016-17), which is more specific than the bare name suggests. It does not explicitly distinguish itself from the sibling get_player, though the 'every season / across seasons' scope implies the difference.

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?

No when-to-use guidance and no alternatives named. An agent is left to infer that this is the historical companion to get_player rather than being told so.

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