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

No annotations are provided, so the description carries the full burden, and it discloses useful behavior: results are ranked by severity, reasons are plain-language, only current U.S. airspace disruptions are included, and private-aircraft restrictions are segregated. It does not state read-only safety or any rate/auth characteristics, which is a modest remaining gap for a no-annotation tool.

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?

Three tight sentences, front-loaded with the resource and scope, then the categorization caveat, then the exclusion. No filler; every clause adds information an agent needs.

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-param read tool with no output schema and no annotations, the description covers what is returned (current disruptions ranked by severity with plain-language reasons), the geographic scope, and the interpretive caveat. Nothing essential for correct invocation or interpretation is missing.

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 100%, but the single schema description is only 'true or false', so the description's mention that restrictions are 'separated out' is the main clue to what includeRestrictions controls. It still doesn't state the default or the exact effect of true vs false, so it adds only partial meaning over the terse schema.

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+scope: 'Every current FAA disruption in U.S. airspace, ranked by severity,' then enumerates the exact disruption types it covers (ground stops, GDPs, arrival/departure delays, airspace flow programs, closures). This is clearly distinguishable from siblings like travel_airport_status and travel_airport_forecast, which are airport-specific.

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?

Gives a clear when-not ('Not for flight planning') and a usage caveat that steers agent behavior (private-aircraft-only restrictions separated out so they aren't reported as closures). It stops short of naming the sibling an agent should use for flight-planning or single-airport queries, so routing is only partially closed.

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