get_weather

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

No annotations are provided, so the description carries full behavioral burden. It indicates a read-only operation fetching real-time data, but does not disclose error handling, data source freshness, or any limitations. This is acceptable for a simple tool but could be more transparent.

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 sentence with no unnecessary words. It front-loads the action and resource, making it highly efficient and easy to parse.

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 simple with two required parameters and no output schema. The description mentions 'weather and temperature', hinting at the output structure. It adequately covers the functionality for a straightforward lookup, though it could detail additional return fields.

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 descriptions for 'latitude' and 'longitude' already define the parameters clearly. The description adds 'specific GPS coordinates' which is redundant. With 100% schema coverage, the description provides no additional meaning, scoring the baseline of 3.

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 verb 'Fetches' and the resource 'current real-time weather and temperature' for specific GPS coordinates globally. It accurately reflects the tool's function with no 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?

The description implies usage for any global location via GPS coordinates. Without sibling tools, no alternatives are needed, and the scope is clear. It lacks explicit when-to-use or when-not-to-use guidance, but is adequate for a single-purpose tool.

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