seriea_competitions

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

The description adds 'Auth: none needed' and specifies the return structure, which goes beyond the readOnlyHint and idempotentHint annotations. It does not contradict any annotations. It lacks details on pagination or regional coverage, but these are not critical for a simple listing endpoint.

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 concise and front-loaded with the tool's purpose, followed by a clear return format and an auth note. Every sentence earns its place with no filler 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 endpoint, the description provides the essential return contract and auth status. It does not explain that the locale parameter affects label language, but the schema covers that. Overall it is sufficient for an agent to understand the tool's output and 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?

The single optional locale parameter is fully described in the schema with 'Label language' and a default value, so the description does not need to elaborate. The tool description adds no additional semantic context beyond what the schema already provides.

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 identifies the tool as returning all Lega Serie A competitions (Serie A, Coppa Italia, Super Cup, Primavera) with their SDP competitionId. This specific verb+resource scope distinguishes it from sibling tools for other leagues and from related Serie A tools like seriea_seasons or seriea_standings.

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 explicit guidance is provided on when to use this tool versus alternatives. While the description implies listing competitions, it does not mention exclusions, alternatives, or prerequisites. Sibling tools such as seriea_competition or seriea_seasons are not referenced, leaving the agent to infer the intended use case.

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