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

No annotations are provided, so the description carries the full burden. It usefully discloses the 25-code cap and the 'worst first' ordering, but says nothing about auth requirements (only the schema hints at a token), what happens if the cap is exceeded, or whether it's strictly read-only.

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?

A single efficient sentence with the key constraint (25 codes) and output ordering ('worst first') packed in. The leading 'PRO.' token is cryptic but short and presumably signals a tier.

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 no output schema and no annotations, the description should say more about what an alert result looks like and how 'worst first' is determined. It covers the core call correctly but leaves the agent guessing about return content and edge cases.

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 coverage is only 50%: access_token is documented in the schema but postal_codes is bare. The description partially compensates by clarifying that postal codes represent stores, job sites, and depots, but gives no format or country expectations for the strings.

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 gives a specific verb ('Check') and resource ('postal codes') and states the payload clearly: active alerts for up to 25 locations. It doesn't explicitly differentiate itself from area_alerts or weather_alerts, so it stops short of a 5.

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 'at once' and the list of location types (stores, job sites, depots) imply batch triage usage, but there is no explicit when-to-use or when-not guidance, and neither sibling is mentioned as an alternative.

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