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

With no annotations, the description carries the full burden, and it does disclose the most important behavioral fact: the live source is not wired, so calls return UNKNOWN and are never charged. It stops short of describing what a wired/future response contains, latency, or how UNKNOWN should be interpreted by the caller. The accuracy and uptime statistics are unverifiable marketing claims that sit oddly next to the admission that the source is a stub.

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?

It is a single compact sentence and the critical caveat is front-loaded in parentheses, which is good. However, roughly half the text is trust-badging ('100% golden accuracy (78/78)', '100% uptime (24h)', 'data as of 2026-10-26') that does not help an agent select or invoke the tool.

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 explain the return shape (what fields beyond citations, what UNKNOWN looks like) and the coordinates. It conveys only that the tool is a stub and cites pages, leaving an agent unable to predict a response or interpret an UNKNOWN result beyond 'not charged'.

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 0% and the description says nothing about lat/lon — no format guidance, no coordinate system, no note that both are required or that out-of-range values will be rejected by the schema bounds. Latitude/longitude are conventional enough to be partly self-evident, which keeps this above 1.

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 text restates the tool name and then describes only its current operational status (BETA, returns UNKNOWN). It never says what airspace is being checked — restrictions, classes, drone/geofence limits, or regulatory clearance — so an agent cannot tell what this tool actually answers or how it differs from siblings like check_use_allowed or spray_check.

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?

There is no statement of when to use this tool, when not to, or which sibling to prefer. The only usage-adjacent signal is 'free ... returns UNKNOWN without charge', which describes cost, not selection criteria.

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