US city transportation-noise exposure (measured)

get_us_city_noise_exposure
Read-onlyIdempotent

Answers "loudest cities in the US", "quietest cities in the US", "how noisy is Boston", "what share of Miami hears highway noise". Share of residents exposed to ≥60 dB / ≥70 dB transportation noise for all 297 US cities of 100,000+ residents, computed from the federal BTS 2020 National Transportation Noise Map, not estimated. Pass a city for detail, omit for the ranking. Street address → get_address_noise; neighborhoods → get_neighborhood_noise.

TDQS

A4.5/5.0
Behavior4/5

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

Annotations already indicate read-only, idempotent behavior. The description adds valuable context: data source (federal BTS map), measured not estimated, specific dB thresholds, and city coverage.

Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

Conciseness5/5

Is the description appropriately sized, front-loaded, and free of redundancy?

Two concise sentences, no waste. First sentence gives purpose and examples, second provides technical details and alternatives. Information is front-loaded.

Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

Completeness5/5

Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

Given two optional parameters and an existing output schema, the description covers purpose, usage, data source, and sibling differentiation completely.

Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

Parameters4/5

Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

Schema coverage is 100% with descriptions; the description complements by explaining usage patterns ('pass a city for detail, omit for ranking') and providing examples, adding value beyond schema.

Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

Purpose5/5

Does the description clearly state what the tool does and how it differs from similar tools?

The description clearly states the tool answers specific questions about US city noise exposure using measured data, and explicitly distinguishes from sibling tools (get_address_noise, get_neighborhood_noise).

Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

Usage Guidelines4/5

Does the description explain when to use this tool, when not to, or what alternatives exist?

The description explains when to pass a city vs omit for ranking, and mentions alternative tools for address or neighborhood queries, providing clear usage context.

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

A4.4/5.0
Disambiguation5/5

Each tool has a clearly distinct purpose: address-level noise, city-level estimated (world), city-level measured (Europe), US city exposure, neighborhood ranking, ordinance info, sound level lookup, safe exposure time, and app information. Overlaps are minimal and well-documented in descriptions.

Naming Consistency5/5

All tool names follow a consistent verb_noun pattern (get_, list_, lookup_, safe_). Naming conventions are uniform, using lowercase with underscores, making it easy to predict tool names from the domain.

Tool Count5/5

With 10 tools, the server is well-scoped for its purpose of providing noise information. Each tool covers a specific aspect of the domain without redundancy, and the number is within the ideal 3-15 range.

Completeness4/5

The tool set covers address, neighborhood, US city, European city, and world city noise, plus sound levels, safe exposure, and some ordinances. Minor gaps include limited ordinance coverage (only 8 US cities) and lack of noise data for non-European/non-US regions, but core queries are addressed.
