pl_player_season_stats

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

With no annotations, the description must disclose behavior. It only states the purpose and return type, omitting whether it is read-only, any side effects, or authentication needs. The agent cannot infer safety or side effects.

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 minimal, comprising two sentences that front-load the purpose. No extraneous information, though it could benefit from parameter clarification without sacrificing conciseness.

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 no output schema and no annotations, the description is too brief. It lacks details on parameter meanings, constraints, and the exact structure of the returned data, forcing the agent to rely on external knowledge.

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 three parameters (cid, pid, sid) have no descriptions in the schema (0% coverage). The description does not explain what they stand for, leaving the agent to guess that cid is competition, pid is player, sid is season.

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 returns a player's stats for one season and mentions the return structure including Opta metrics. It is specific but does not explicitly differentiate from similar tools like pl_player_comp_stats.

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 guidance is provided on when to use this tool versus alternatives such as pl_player_info or pl_player_comp_stats. The agent does not know prerequisites or exclusions.

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