get_weather_summary

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

The description discloses that data comes from external sensors via multicast, providing some behavioral context. However, with no annotations, it fails to explicitly state that the operation is read-only, idempotent, or if any permissions are needed. The description is adequate but not fully 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 extremely concise with two sentences for purpose and one for the parameter. No redundant information. Front-loaded with the key purpose. Every word 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 the presence of an output schema, return values need not be described. However, the missing usage guidelines and behavioral transparency gaps make the description less complete than it could be for a tool with no annotations. It covers core purpose but not context of use.

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 parameter house_id has no description in the schema (0% coverage). The description adds only an example ('h1') and states it's a house identifier, but does not explain how to obtain valid IDs, the default behavior, or what happens if omitted. This adds minimal value beyond the parameter name.

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 outdoor weather data including temperature, humidity, wind, and rainfall. It names the specific sensor type and protocol, but does not explicitly differentiate from sibling tools like get_sensor_data, which may also return weather-related measurements.

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 on when to use this tool versus alternatives such as get_sensor_data. No mention of prerequisites, constraints, or situations where this tool is inappropriate. The description only states what it does without context for selection.

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