v1.0.0Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
Annotations already declare readOnly, idempotent, openWorld and non-destructive, so the safety profile is fully covered by structured data. The description adds one genuinely non-redundant behavioral fact — no authentication is required — but says nothing about refresh cadence, data staleness, or session prerequisites for a live feed.
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?
Two short sentences with zero waste: the payload is front-loaded and the auth caveat trails it briefly. Nothing could be removed without losing information.
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?
With an output schema present there is no need to explain return values, annotations cover the safety profile, and there are no parameters to document. The remaining gap is disambiguation from the sibling weather tools, which the description does not address.
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 takes zero parameters, so the baseline of 4 applies. The description's enumeration of returned weather fields is informative but is really return-value content, which the existing output schema already covers.
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?
States a specific verb+resource (live track weather) and enumerates the data returned (air/track temp, humidity, wind, rain), which is more concrete than the title alone. It does not, however, differentiate itself from the sibling tools get_weather and get_weather_data, so an agent must infer that this variant is the 'live' one from the name prefix alone.
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 'no auth required' note gives a usable precondition, and the 'live' qualifier implies usage during an active session. But there is no explicit when-to-use statement nor any naming of alternatives (get_weather, get_weather_data), leaving the choice between the three weather tools to inference.
Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.
