Emergency numbers

get_emergency_numbers

Read-onlyIdempotent

Emergency numbers for one country: data.numbers.value {police, ambulance, fire, general, all_numbers}. A role without its own number is null: then use general, else all_numbers (in 58 countries only all_numbers is filled). Use it when only these numbers are needed; get_country_facts for several facts, get_trip_brief for a whole trip. No data for the country is a not-found error. Each fact is cited: sources[] (url, license), last_verified, confidence. Parameters: country is where the call will be made (the traveller's location, not home); alpha-2 works best. Example: {"country":"JP"}. Read-only; keyless (free key or x402 lifts limits: https://citedtravel.com/pricing/); errors RFC 9457.

A4.6/5.0

Behavior4/5

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

Annotations already carry the safety profile (readOnlyHint, idempotentHint, destructiveHint:false, openWorldHint:false), and the description partly repeats 'Read-only'. However it adds genuinely new behavioral context: not-found error on missing data, RFC 9457 error format, and keyless/free-key/x402 rate-limit behavior with a pricing link. Strong, with only minor redundancy against the annotations.

Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

Conciseness4/5

Is the description appropriately sized, front-loaded, and free of redundancy?

Front-loaded with purpose, response shape, then usage/fallback/error/auth, so an agent reading top-down gets the essentials first. It is dense and clause-heavy in places (citation fields, error format, pricing all packed into a single block), costing some scannability, but almost every sentence earns its place.

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

Completeness5/5

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

Output schema exists so return values needn't be spelled out, yet the description still flags citation metadata (sources[], last_verified, confidence) and the null-role fallback. Combined with annotations covering safety and explicit error/auth behavior, an agent has everything needed to invoke it correctly.

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

Parameters4/5

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

Schema coverage is 100%, so baseline is 3, but the description adds meaning the schema does not: country is 'where the call will be made (the traveller's location, not home); alpha-2 works best' and an inline example. That semantic clarification (call location vs. home country) is real added value; lang is left to the schema.

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+resource (emergency numbers for one country) and even names the response shape (data.numbers.value with the five role keys). It explicitly distinguishes itself from siblings: 'Use it when only these numbers are needed; get_country_facts for several facts, get_trip_brief for a whole trip.' An agent can route without opening any schema.

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

Usage Guidelines5/5

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

Gives explicit when-to-use ('when only these numbers are needed') plus named alternatives with their selecting conditions (get_country_facts, get_trip_brief). It also handles the fallback branch ('A role without its own number is null: then use general, else all_numbers'), leaving little to inference.

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