compare_players

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

No annotations are provided, so the description carries full burden. It states the tool compares players but does not disclose what the comparison entails (e.g., which statistics, side effects, or data scope). The behavior is minimally described.

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 description is a single front-loaded sentence, which is concise. However, it is too brief and could be expanded without losing conciseness. It earns its place but lacks completeness.

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?

Given the tool has 3 parameters and an output schema, the description is incomplete. It does not explain what the output represents, the scope of comparison, or any limits. The existing output schema reduces the need to describe return values, but the description still lacks essential context.

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 must compensate. It adds that player1 and player2 accept names or IDs, which is helpful, but it does not explain the optional 'season' parameter or any format constraints. The description adds marginal value over 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 description clearly states it compares two players side by side, which is a specific verb and resource. It distinguishes from sibling tools like get_player_stats or get_player_info, which focus on single players. However, it could be more precise about what attributes are compared.

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 mentions it accepts names or IDs, giving basic input guidance. However, it provides no context on when to use this tool versus alternatives (e.g., when to use get_player_stats instead), no exclusions, and no prerequisites.

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