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

No annotations provided, so description carries full burden. It discloses the need for an AirLabs API key, rate limit of 1000 calls/month, and the return fields (name, country, codes, status). Missing error handling details but sufficient.

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?

Description is concise with a header, short intro, and bullet-pointed Args. No unnecessary information. Every sentence adds value.

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?

Given no output schema, the description explains the return fields. Parameter descriptions are clear. For a simple lookup tool, it is complete enough, though simultaneous parameter usage could be clarified.

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 has 0% coverage, but description provides detailed examples for each parameter (e.g., 'LH' for Lufthansa) and explains that they are search criteria. It adds meaning beyond the schema's basic type definitions.

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?

Description clearly states 'Airline-Details abrufen (AirLabs)' and explains it searches by IATA code, ICAO code, or name. This distinguishes it from sibling tools like get_airport_info or track_flight.

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?

The description says to search by code or name and mentions needing an API key with rate limits. It does not explicitly exclude other uses but is clear enough for an agent to decide when to use it.

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

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

With no annotations provided, the description does not disclose behavioral traits such as rate limits, authentication requirements, or data freshness. It only states the basic purpose, leaving agents unaware of important operational constraints.

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?

The description is short and front-loaded with the tool's purpose. Parameter explanations are clear and contained within a structured docstring format. No superfluous information is present.

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 simple two-parameter tool without output schema, the description adequately covers parameter semantics. However, it omits details about the return format, pagination, or error handling, which could be useful for completeness.

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?

Despite 0% schema description coverage, the description provides concrete examples for airport_icao (e.g., EDDF, KJFK, EDDM) and explains the hours parameter with default and maximum values. This adds significant clarity beyond the bare schema.

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 clearly states 'Letzte Ankünfte an einem Flughafen abrufen (OpenSky)' meaning 'Retrieve latest arrivals at an airport'. It specifies the resource (arrivals) and action (retrieve), and it effectively distinguishes from siblings like get_airport_departures.

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?

The description implies usage for airport arrivals, but lacks explicit guidance on when to use this tool versus alternatives like get_airport_departures. No exclusions or context are provided, relying on sibling names for differentiation.

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

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

The description mentions 'OpenSky' as the data source and includes a time range parameter, but it fails to disclose critical behavioral traits such as authentication requirements, rate limits, pagination behavior, error handling, or whether incomplete data may be returned. The lack of annotations increases the burden on the description, which is not met.

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?

The description is succinct (two sentences plus argument list) and front-loaded with the purpose. Every sentence adds value: the first line states the function, the 'Args' section documents parameters. No redundant or extraneous text.

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 simple listing tool with two parameters and no output schema, the description covers the core functionality and parameter details. However, it omits information about the return format, result count, or potential errors, which would enhance completeness for an agent. Still, it is mostly adequate given the tool's low complexity.

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?

With 0% schema description coverage, the description fully compensates by providing clear explanations for both parameters: 'airport_icao' includes concrete ICAO code examples (EDDF, KJFK, EDDM), and 'hours' specifies default (2) and maximum (24) values, adding significant meaning beyond the schema's minimal titles and types.

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?

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?

Given no output schema, the description partially covers return values but lacks details on structure or error behavior. It also omits usage constraints (e.g., providing at least one param) and does not differentiate from siblings despite sibling list existing.

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 0%, so description must add meaning. It lists params with examples (e.g., IATA 'JFK') and indicates they are search filters. However, it does not explain mutual exclusivity or whether multiple can be combined, leaving ambiguity.

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 clearly states it retrieves airport details (Flughafen-Details) and specifies search by IATA, ICAO, or country code. It lists return data (name, location, timezone) and distinguishes from siblings like arrivals/departures/weather.

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 mentions API key requirement and call limit, but does not explicitly state when to use this tool versus siblings or how to combine parameters. It implies one search criterion but does not clarify if multiple are allowed or if at least one is required.

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

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

No annotations provided; description adds context on data content (wind, visibility, etc.) but omits details like data freshness, rate limits, or authentication needs.

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

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

The description clearly states the tool retrieves current flight weather (METAR) at an airport, with a list of data included. The tool name and context signal 'get_weather_forecast' as a sibling distinguish it as real-time vs. forecast.

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?

The description implies usage for current weather but does not explicitly state when to use this tool vs. siblings like 'get_weather_forecast' or any exclusions.

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

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

No annotations are provided, so the description must bear full responsibility for behavioral disclosure. It only states what the tool does (retrieve warnings) without mentioning any traits such as data freshness, update frequency, output format, or potential rate limits. This leaves agents under-informed about what to expect.

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?

The description is concise and front-loaded: the first sentence states the main action, and the second adds explanatory detail about SIGMETs. Every sentence is informative, and there is no redundant information. It is appropriately sized for the tool's simplicity.

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?

Given the tool has no parameters and no output schema, the description should inform the agent about the return value. It does not mention the response structure (e.g., list of warnings, format), which is a gap. However, for a simple retrieval tool with no complexity, the description is minimally adequate but could be improved by specifying output type.

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?

The tool has zero parameters and 100% schema coverage (since the schema is empty). According to guidelines, a baseline of 4 applies when there are no parameters; the description does not need to add parameter-specific details. The description appropriately focuses on the tool's purpose.

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 clearly states the tool retrieves active SIGMETs and aviation weather warnings worldwide, and explains what SIGMETs warn about (thunderstorms, icing, turbulence, etc.). It uses a specific verb ('abrufen' meaning 'retrieve') and identifies the resource, distinguishing it from sibling tools like get_airport_weather or get_weather_forecast which focus on general weather or specific locations.

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?

The description provides context on when to use the tool—to access active global aviation warnings—and explains the types of hazards covered. However, it does not explicitly state when not to use it or mention alternative tools for related tasks such as airport-specific weather or flight tracking, though the sibling names imply different scopes.

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

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

No annotations are provided, and the description does not disclose behavioral traits such as error handling (e.g., if no track exists), data freshness, or whether the tool is read-only. For a retrieval tool, this is a significant gap.
