Remove Player From Market

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 clarifies that this cancels a listing, but does not state whether the action is reversible, whether the player returns to the squad, what permissions are required, or what happens if the player is not listed.

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?

The single sentence is front-loaded and efficient, with no wasted wording. Its brevity is appropriate structurally, though it leaves important behavioral and parameter details unspecified.

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?

This is a mutation tool with no annotations, no output schema, and no parameter descriptions, so the description needs to do more. It gives the core action but omits permissions, side effects, error cases, and the role of league_id, leaving an agent under-informed for safe invocation.

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%, so the description should compensate for both parameters. It implies that a player ID identifies the listed player, but it does not explain player_id or league_id, nor does it clarify when league_id should be supplied.

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 states a specific verb and resource: taking a listed player off the transfer market, with parenthetical clarification that this cancels the listing. This clearly distinguishes it from siblings like list_player_for_sale, sell_player_to_kickbase, and withdraw_offer.

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?

The description implies the tool is used when the manager wants to cancel their own active listing. However, it does not explicitly say when to use this versus related actions such as sell_player_to_kickbase or what to do if the player is not currently listed.

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