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

Annotations already declare readOnlyHint=true, idempotentHint=true, destructiveHint=false, and openWorldHint=false, so the safety profile is covered. The description adds that matching is over curated "short answers" rather than documents, and that both keyword strings and natural-language questions are accepted, but says nothing about ranking, result shape, or language handling.

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?

A single front-loaded sentence: purpose first, then a colon-delimited topic list that helps agents match user phrasing. The topic enumeration is long and partly redundant with sibling tool names, but it earns its space as query-matching vocabulary.

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 read-only search with no output schema, the description covers intent but omits what an agent needs to call it well: whether `lang` constrains the query or the results, that `limit` defaults to 5, and what a hit looks like. Annotations carry the safety story, so the gap is moderate rather than severe.

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 coverage is only 33%: "query" is documented and the description essentially restates it ("by keywords or a full question"). Neither `lang` (search/output language? which of 23 locales?) nor `limit` (default 5, capped at 20) is explained anywhere, so the description fails to compensate for the documentation 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?

The description gives a clear verb+resource ("search short answers about Dumaguete") and enumerates the topical breadth it covers (rent, visas, weather, forum, marketplace), which lets an agent recognize it as the general free-text lookup. It does not, however, explicitly contrast itself with the seven sibling topic tools, even though their coverage overlaps.

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?

It says how to query ("keywords or a full question") but never states when to prefer this tool over get_dumaguete_costs, get_dumaguete_weather, or the other siblings whose subject matter it duplicates. There are no exclusions or routing hints for an agent facing eight overlapping Dumaguete tools.

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