weather_uae_all

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

Annotations already declare readOnlyHint, idempotentHint, openWorldHint and destructiveHint=false, so the safety profile is fully covered without the description. The description adds only the batch-efficiency trait ('all 6 ... in a single call'); the TAF slowness note lives in the schema, not the description. Useful but modest added value.

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?

One sentence, front-loaded with the verb and resource, with the scoping detail ('all 6 UAE airports') and the batch benefit placed where it is read first. No 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?

For a zero-required-parameter, single-boolean tool with an output schema and full annotation coverage, this is sufficient: the agent knows it returns METAR for exactly six airports, that TAF is opt-in via the schema, and that the operation is a safe read.

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 description coverage is 100% and the single optional parameter (include_taf) is documented there, including its default and the 'slower' trade-off. The description adds nothing beyond the schema, so the baseline 3 applies.

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 and resource ('Get METAR observations') and adds a concrete scope ('all 6 UAE airports'), which implicitly separates it from the single-airport sibling weather_uae_icao. It stops short of naming that sibling, so the differentiation requires the agent to infer it from the sibling list.

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 phrase 'in a single call' implies this tool is the batch option, but there is no explicit when-to-use statement, no exclusion, and no named alternative (e.g. 'for a single airport use weather_uae_icao'). Usage is only inferable.

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