adsb_pia

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 does not state that this is a read-only feed, whether results are live or historical, whether it covers a global or bounded area, or any rate/coverage caveats. Only the acronym expansion adds context.

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 tight sentence with no filler, and the defining characteristic (randomized hex codes) is front-loaded. The only cost is that the terseness comes at the expense of stating an action.

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 zero params and an output schema present, return-value details need not be explained. Still, for a dataset tool in a crowded ADS-B family, the description leaves unclear what the call actually returns operationally (full list? filtered? live?) and how it relates to adsb_ladd, which is the main thing an agent needs to call it correctly.

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 there is nothing for the description to disambiguate; the baseline of 4 applies. No parameter-related gaps exist.

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 names the resource (aircraft using Privacy ICAO Address) and usefully decodes the PIA acronym plus the 'randomized hex codes' characteristic. But it is a noun fragment with no verb — an agent cannot tell whether the tool lists, queries, or summarizes these aircraft. Siblings like adsb_ladd and adsb_by_hex share the same surface form, and nothing distinguishes this one beyond the acronym.

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 when-to-use guidance at all. The obvious sibling adsb_ladd (another privacy-filtered ADS-B feed) and adsb_by_hex (lookup by hex code) are never mentioned, so an agent has no routing rule for choosing among the ADS-B tools.

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