get_leagues_by_country_id

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

No annotations are provided, so the description must carry behavioral disclosure. It only states 'get all leagues' without mentioning pagination, sorting, includes, or performance implications. The agent is left unaware of important behaviors like pagination.

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 very short but lacks structure and detail. While concise, it sacrifices completeness. Critical information about pagination and includes is omitted.

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?

With 8 parameters, no output schema, and no annotations, the description is incomplete. It fails to indicate return format, page limits, or how includes work. Sibling tools suggest complex usage, but the description offers no help.

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 has 100% coverage, but the description adds no meaning beyond the schema. It does not explain relationships between parameters (e.g., required country_id vs optional pagination) or provide usage context.

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 the action ('get all leagues') and the scope ('in a specific country'). It effectively distinguishes from siblings like get_all_leagues (no filter) and get_leagues_by_team_id.

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 usage when a country_id is available, but does not explicitly state when not to use or mention alternatives like get_all_leagues. Context from sibling names helps, but the description itself lacks guidance.

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