openligadb_sports

Read-only

List OpenLigaDB's complete current sports directory, including source ids and names. Use openligadb_leagues to discover the full league-season catalog; the source currently includes 13 sports and its Test category.

Behavior4/5

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

Annotations already declare readOnlyHint and openWorldHint, so the safety profile is covered. The description adds valuable data-scope context — the source currently has 13 sports and includes a 'Test' category — which warns the agent about a junk entry it would otherwise be surprised by. It stops short of noting volatility of 'current' beyond that.

Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

Conciseness5/5

Is the description appropriately sized, front-loaded, and free of redundancy?

Two sentences, both earning their place: the first defines scope and return fields, the second routes to the sibling and flags the dataset size. The purpose is front-loaded ahead of the disambiguation.

Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

Completeness4/5

Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

With an output schema present and no input parameters, the description carries little burden, and it covers the dataset scope plus the sibling relationship. A note on how 'current' changes over time would make it airtight, but nothing an agent needs in order to call it is missing.

Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

Parameters4/5

Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

The tool takes zero parameters, so the baseline is 4; there is no parameter semantics to explain and the description correctly does not invent any.

Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

Purpose5/5

Does the description clearly state what the tool does and how it differs from similar tools?

States a specific verb and resource ('List ... complete current sports directory') and specifies the returned fields (source ids and names). It is clearly differentiated from openligadb_leagues, which is named explicitly as the league-season catalog.

Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

Usage Guidelines5/5

Does the description explain when to use this tool, when not to, or what alternatives exist?

Explicitly routes the agent: use this for the sports directory, use openligadb_leagues for the full league-season catalog. The when-to-use and the alternative are both stated, leaving nothing to inference.

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