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

Annotations already declare readOnly, idempotent, non-destructive and closed-world behavior, so safety is covered. The description usefully adds the topical scope of what will be returned, but says nothing about the response form (prose text) or that output is localized.

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?

One compact sentence that front-loads the purpose ('How to reach Dumaguete and get around') and then lists covered modes. The enumeration is dense but every item is informative, with no filler.

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?

No output schema exists, so the description should carry more of the burden; it adequately conveys content scope for a simple read-only info tool. It is incomplete regarding the lang parameter's effect on the returned content, which is the main thing an agent needs before calling.

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% and the description never mentions the single 'lang' parameter, so its meaning (output language) must be inferred entirely from the enum values. With one undocumented parameter, the description fails to compensate for the coverage gap.

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?

States a specific resource and enumerates its contents (airport, ferries, buses, tricycles/jeepneys), so an agent knows exactly what topical information it returns. It does not explicitly distinguish itself from siblings like get_dumaguete_places or get_dumaguete_topic, which overlap in the 'about Dumaguete' space.

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?

No when-to-use, when-not-to-use, or alternative routing is given; nothing tells the agent why to pick this over get_dumaguete_places or search_dumaguete_answers. The content scope implicitly defines the topic, but that is inference, not guidance.

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