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

No annotations are provided, so the description carries full burden. It states the tool retrieves data ('Get'), implying a read-only operation, but doesn't disclose behavioral traits like whether it returns all barangays at once (pagination?), what format the output takes, error conditions, or any rate limits. The description is minimal and lacks essential context for safe invocation.

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 a single, efficient sentence that front-loads the core purpose without unnecessary words. Every part of the sentence contributes directly to understanding the tool's function, making it appropriately concise for a simple retrieval operation.

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 lack of annotations and output schema, the description is incomplete. It doesn't address key aspects like return format (list of barangays? structured data?), error handling, or how results are presented (e.g., sorted, limited). For a tool with no structured metadata, this minimal description leaves too many operational questions unanswered.

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?

Schema description coverage is 0%, so the description must compensate. It mentions 'specific island group' which relates to the 'islandGroupCode' parameter, but doesn't explain what an island group is, provide examples of valid codes, or describe the expected format (e.g., string patterns). This leaves the parameter meaning ambiguous despite the low schema coverage.

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 verb ('Get') and resource ('all barangays within a specific island group'), making the purpose immediately understandable. However, it doesn't explicitly differentiate from similar sibling tools like 'get_barangays' or 'get_barangay', which could retrieve barangays without island group filtering.

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 alternatives. With many sibling tools for retrieving barangays (e.g., 'get_barangays', 'get_barangay', 'get_province_barangays'), there's no indication of when this specific island-group-filtered version is appropriate or what distinguishes it.

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