Criora: climate & disaster risk for any place

Natural disasters happening near a place

get_hazards_near

Read-onlyIdempotent

Natural disasters and hazards happening now or recently near a place, every one the sources hold: wildfires (NASA FIRMS satellite fire detections), every earthquake USGS records with its depth, felt reports, intensity and PAGER alert, tsunami bulletins of the NOAA warning centres, tropical cyclones with the official NHC cone and forecast track, floods, volcanic eruptions and droughts (GDACS), official warnings for every natural hazard from the US National Weather Service and, through WMO WIS2, from MeteoAlarm's national services across Europe (wind, snow and ice, thunderstorms, fog, heat, cold, coastal, rain, flood, fire danger, avalanche), and air quality (OpenAQ reference monitors).

Use it for what is happening there now. For the weather forecast use get_forecast; for long-term exposure, get_climate_profile.

Returns the most severe and most recent events first, each with its kind (occurrence or warning), type, severity (low to critical), distance, bearing and time; a warning also carries its issuer (sender), issued_at, onset_at and expires_at and whether the place lies inside its area (inside), and a moving storm its track. total and counts_by_type cover every event found. radius_km (1 to 500), event_types and days (1 to 30) narrow the search; without radius_km every type is searched at its largest distance, which radius_used_km reports. Give latitude and longitude, or a place name.

Input Schema

Name	Required	Description
`days`	No	Only events of the last N days, 1 to 30; all current when omitted
`place`	No	A place name or address, used only when latitude and longitude are not given. It is resolved to its best match by a geocoder shared by every user and limited to one lookup a second, so pass coordinates when you have them
`latitude`	No	Latitude of the place asked about, in degrees, WGS84. Give it with longitude, or give place instead
`longitude`	No	Longitude of the place asked about, in degrees, WGS84. Give it with latitude, or give place instead
`radius_km`	No	Search radius in km, 1 to 500; the largest when omitted
`event_types`	No	Only these kinds of event; every kind when omitted

Output Schema

Name	Required	Description
`data`	Yes	The most severe and most recent events
`total`	Yes
`center`	Yes
`listed`	Yes
`generated_at`	Yes
`resolved_from`	Yes	What a place name was resolved to; null when coordinates were given
`counts_by_type`	Yes	Every event found, by type
`radius_used_km`	Yes	The distance searched for each event type

A4.5/5.0

Behavior4/5

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

Annotations already cover the safety profile (readOnlyHint, openWorldHint, idempotentHint, destructiveHint=false), so the description is free to add real behavior: results are ordered most-severe and most-recent first, radius_used_km reports the effective radius, and event counts cover every event found. It also warns that place-name lookup goes through a shared geocoder throttled to one lookup per second — a useful non-obvious operational constraint. It does not discuss failure modes or latency across the many upstream feeds, so not a full 5.

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

Conciseness3/5

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

The usage and return-value guidance is well front-loaded and tightly worded, but the opening sentence is a very long run-on with a deeply nested parenthetical list of sources and hazard sub-types (wind, snow and ice, thunderstorms, fog, heat, cold, coastal, rain, flood, fire danger, avalanche). The detail earns its place factually, but the packing hurts scannability and buries the essential 'hazards near a place' claim.

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?

The tool is complex — six parameters, seventeen event types, many upstream feeds — and the description covers location input rules, radius/days narrowing, default behavior, result ordering, and the shape of both occurrences and warnings. With an output schema present, no return-value enumeration is needed, so nothing an agent needs in order to call it correctly is missing.

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 description coverage is 100%, so the baseline is 3; the description earns above that by explaining the coupling between parameters — omitting radius_km searches every type at its largest distance and radius_used_km reports what was applied, and latitude/longitude take precedence over place. Those are semantics the schema alone does not convey.

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 ('Natural disasters and hazards happening now or recently near a place') and goes further by enumerating the underlying sources per hazard family (NASA FIRMS, USGS, NOAA, GDACS, NWS, MeteoAlarm/WIS2, OpenAQ). This is unmistakable against siblings like list_hazards or get_map_events, and the 'now or recently' scope qualifier is explicit.

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?

Explicitly says 'Use it for what is happening there now' and then names the alternatives with the condition that selects them: get_forecast for weather forecasts, get_climate_profile for long-term exposure. This is exactly the when-to-use/when-not/alternative triad.

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