get_island_groups

get_island_groups

Retrieve a complete list of all island groups in the Philippines using the Philippine Standard Geocoding (PSGC) API. This tool provides structured geographic data for mapping, analysis, or reference purposes.

Behavior2/5

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

No annotations are provided, so the description carries the full burden of behavioral disclosure. It states it 'List[s] all island groups', implying a read-only operation, but doesn't cover critical aspects like whether this returns a complete list, pagination behavior, error conditions, or data freshness. For a tool with zero annotation coverage, this is a significant gap in transparency.

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?

The description is a single, efficient sentence that front-loads the key action and resource. There's zero waste—every word contributes directly to understanding the tool's purpose without unnecessary elaboration or fluff.

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

Completeness3/5

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

Given the tool's simplicity (0 parameters, no output schema, no annotations), the description is minimally adequate. It states what the tool does but lacks details on behavior, output format, or sibling differentiation. Without annotations or output schema, more context (e.g., return structure, limitations) would improve completeness for agent use.

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 has 0 parameters, and the schema description coverage is 100% (since there are no parameters to describe). The description doesn't need to add parameter semantics, and it correctly doesn't mention any. A baseline of 4 is appropriate as it avoids misleading or redundant information about non-existent parameters.

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

Purpose4/5

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

The description clearly states the verb 'List' and the resource 'all island groups in the Philippines', making the purpose immediately understandable. However, it doesn't explicitly differentiate from sibling tools like 'get_island_group' (singular) or 'get_island_group_provinces', which might retrieve related but different data, so it falls short of a perfect score.

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

Usage Guidelines2/5

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

The description provides no guidance on when to use this tool versus alternatives. With many sibling tools available (e.g., 'get_island_group' for a single group, 'get_island_group_provinces' for details), there's no indication of context, prerequisites, or exclusions, leaving the agent to guess based on naming alone.

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