get_wca_continents

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

With no annotations provided, the description carries the full burden of behavioral disclosure. It states the tool returns a list of continents with names and identifiers, which is helpful. However, it doesn't mention whether this is a read-only operation (implied by 'Get'), potential rate limits, authentication needs, or error conditions. The description adds basic behavioral context but lacks depth for a tool with no annotation coverage.

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 appropriately sized at three sentences, front-loaded with the core purpose. The second sentence adds useful context about regional filtering, and the third clarifies the return structure. There's minimal redundancy, though the 'Returns:' section slightly repeats information from the second sentence.

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 the tool's low complexity (0 parameters, simple list output) and the presence of an output schema (which handles return value documentation), the description is reasonably complete. It covers the purpose, usage hint, and output format. For a straightforward read operation, this provides adequate context without over-explaining.

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 tool has 0 parameters with 100% schema description coverage, so the baseline is 4. The description doesn't need to explain parameters, and it appropriately doesn't mention any. This is correct for a parameterless tool.

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 tool's purpose: 'Get all WCA continents' with the specific verb 'Get' and resource 'WCA continents'. It distinguishes from siblings like 'get_wca_countries' by focusing on continents rather than countries. However, it doesn't explicitly differentiate from other list tools like 'get_wca_events', so it's not a perfect 5.

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 context by mentioning 'regional filtering', suggesting this tool is for obtaining continent data for filtering purposes. However, it doesn't provide explicit guidance on when to use this versus alternatives like 'get_wca_countries' or other geographic tools, nor does it specify prerequisites or exclusions.

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