seriea_seasons

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

Annotations already declare readOnlyHint, openWorldHint, and idempotentHint, covering the safety profile. The description adds useful behavioral context beyond annotations: 'The Serie A competition id is baked in', 'Auth: none needed', and the exact return shape including the seasonName format. This gives the agent extra confidence and practical knowledge without conflicting with annotations.

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 compact and front-loaded, immediately stating the resource and scope. The return format is condensed into a single line, and the auth note is minimal. Every sentence adds value and there is no fluff or redundancy.

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?

For a simple read-only listing tool with one optional parameter and no output schema, the description is complete. It covers what is returned, how to use the result, that no auth is needed, and how the competition ID is embedded. No important information is missing for the agent to invoke and use the tool correctly.

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 input schema already documents 'locale' as 'Label language' with a default of 'en-GB', and schema coverage is 100%. The tool description does not add any additional meaning about the parameter—it never mentions locale or how it affects the output. With full schema coverage, baseline 3 is appropriate.

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 what the tool does: returns all 41 Serie A seasons with seasonId and seasonName. It explicitly positions itself as the starting point for getting a seasonId before drilling into standings/teams/players/matches, which distinguishes it from sibling tools like seriea_standings and seriea_season. The scope is precise and the verb is implied by 'All 41 Serie A seasons'.

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 provides clear usage context: 'start here to get a seasonId, then drill into standings/teams/players/matches'. It tells the agent when to use this tool and what to do next. It does not explicitly state when not to use it or mention alternatives like seriea_season, but the 'start here' guidance is clear enough for a simple listing tool.

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