get_current_weather

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

With no annotations provided, the description carries the full burden of disclosure. It mentions data content and source but does not state read-only behavior, data freshness, units, limitations, or whether any authorization is needed. 'Get' only weakly implies a non-mutating operation.

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 a single, front-loaded sentence that efficiently conveys the essential purpose and scope. Every word earns its place with no redundancy or filler.

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?

The tool is low-complexity with full schema coverage and an output schema, so the description does not need to explain return values. It adequately covers the core purpose and data content, though it omits usage context relative to siblings, which is partially addressed in other dimensions.

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 schema already covers both parameters (lang and region) with defaults and descriptions, so the parameter semantics are fully documented. The description adds no parameter-specific meaning beyond the overall 'HK' scope, which is consistent with the default region.

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 current weather data, including warnings, temperature, and humidity, specifically for Hong Kong from HKO. This distinguishes it from sibling forecast and warning tools, though 'warnings' also appear in dedicated warning tools, creating slight ambiguity.

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?

No guidance is provided on when to use this tool versus alternatives like get_local_weather_forecast or get_weather_warning_summary. The description implies current conditions but does not explicitly exclude other use cases or name alternative tools.

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