transfers

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

No annotations are supplied, so the description carries the full behavioral burden. It does not state that this is a read-only list, whether results are paginated, whether a player/team is required, or what transfer types are covered; only scope is disclosed.

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?

It is a single short fragment with no wasted words, but it is under-specified rather than well-structured. It lacks a verb and any front-loaded operational detail.

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 or annotations, the description should have covered return shape, pagination, filter requirements, or transfer types. It only says transfers by player or team, leaving the agent without enough context to call it confidently.

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 100%, so the schema already explains the team and player ID parameters. The description adds that these are filter dimensions but does not clarify whether both are optional, how they combine, or what IDs mean beyond the schema.

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 fragment names the resource (transfers) and the two filtering dimensions, but it omits a verb such as list or retrieve and does not distinguish itself from sibling stats/events tools. An agent can infer it returns transfer records, but only weakly.

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 guidance on when to use this instead of player_stats, team_stats, or search tools, no prerequisites, and no note on whether both filters can be combined. It only implies that results can be filtered by player or team.

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