Criora: climate & disaster risk for any place

Compare countries' climate and disaster risk

compare_countries

Read-onlyIdempotent

Two to ten named countries side by side: overall risk score, class and world rank, and their climate, nature, social, governance and adaptation scores (0 to 100, higher is riskier; rank 1 is the riskiest of 194). To find the riskiest countries use rank_countries.

A4.2/5.0

Behavior4/5

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

Annotations already declare readOnly, idempotent, closed-world and non-destructive, so safety is covered. Beyond that, the description adds genuinely useful interpretive context the annotations do not carry: scores run 0–100 with higher meaning riskier, and rank 1 is the riskiest of 194 countries, which prevents misreading the output direction.

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?

Two sentences, front-loaded with the operation and its output fields, and the alternative-tool pointer placed last where it belongs. The parenthetical scale explanation earns its space by disambiguating score direction.

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

Completeness4/5

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

With an output schema present, the description need not enumerate return fields, and it correctly focuses on interpretation and tool selection. The only minor gap is the absence of failure behavior for unrecognized country names, which matters given free-text name input.

Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

Parameters3/5

Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

Schema coverage is 100% and both parameters are documented in the schema, including the ISO3-or-name format and the concise/detailed enum meaning, so the schema does the heavy lifting. The description reinforces the 2–10 cardinality and the risk-direction semantics but adds no new parameter-level guidance.

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

Purpose5/5

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

States a specific verb and resource (compare 2–10 named countries side by side) and enumerates exactly what is returned: overall risk score, class, world rank, plus climate, nature, social, governance and adaptation scores. This is clearly distinguishable from single-country siblings like get_country_profile.

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

Usage Guidelines4/5

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

Explicitly routes the agent to rank_countries when the goal is finding the riskiest countries, which is the most likely confusion given the sibling set. It does not address when to prefer get_country_profile for a single country, but that boundary is largely implied by the 'two to ten' framing.

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