Philippine-Geocoding

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

No annotations are provided, so the description carries full burden for behavioral disclosure. While 'List all' implies a read-only operation, the description doesn't address important behavioral aspects like whether this returns all regions at once or uses pagination, what format the regions are returned in, or whether there are any rate limits or authentication requirements for this geographic data service.

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 perfectly concise at just four words, front-loading the essential information ('List all regions') with the geographic scope ('in the Philippines') as necessary context. Every word earns its place with zero wasted text.

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 operation with no parameters and no output schema, the description provides the minimum viable information about what the tool does. However, given the rich ecosystem of sibling tools and lack of annotations, it should ideally provide more context about when to use this versus alternatives and what format the regions are returned in.

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?

With 0 parameters and 100% schema description coverage, the baseline score would be 4 even without parameter information in the description. The description correctly indicates this is a parameterless operation that returns all regions, which aligns perfectly with the empty input schema.

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 ('List all') and resource ('regions in the Philippines'), making the tool's purpose immediately understandable. However, it doesn't explicitly differentiate from sibling tools like 'get_region' (singular) or 'get_island_group_regions', which could cause confusion about when to use this specific list-all tool versus more targeted alternatives.

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 provides no guidance on when to use this tool versus the many sibling tools available. With numerous alternatives like 'get_region' (singular), 'get_island_group_regions', and 'search_by_name', the agent receives no explicit or implied direction about when this comprehensive listing tool is preferred over more specific queries.

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