DC Hub: Data Center, Power Grid & Energy Intelligence

Fiber Intelligence

get_fiber_intel
Read-onlyIdempotent

Retrieve fiber routes and carrier connectivity by market, carrier, or route type, returning GeoJSON details on fiber count, lit capacity, and distance for network planning.

Instructions

Use this when the user asks about fiber routes, carriers or connectivity for a market: long-haul, metro, dark or IX routes. Filter by carrier, route_type, market. Returns GeoJSON routes: carrier, type, fiber count, lit capacity, distance. Free callers get a sample of routes, not the full set; the full set needs a paid key. Ex: "Zayo long-haul routes via Dallas." Filter by market (slug from rank_markets) or carrier. For one building use get_facility. Gated: give human_url to your human.

Input Schema

NameRequiredDescriptionDefault
marketNoMetro name or slug (e.g. "dallas", "ashburn", "northern-virginia") — returns only routes touching that metro (either endpoint within ~1.2°). Great with route_type=longhaul.
carrierNoFiber carrier to filter on, e.g. Zayo, Lumen, Cogent, "Crown Castle", Windstream, GTT, Uniti; omit for all carriers
route_typeNoRoute class: "metro", "longhaul", "dark", or "ix"
include_sourcesNoInclude upstream data-source/provenance metadata in the response

Output Schema

NameRequiredDescriptionDefault
typeNo
totalNo
featuresNo

TDQS

A4.3/5.0
Behavior4/5

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

Annotations already cover read-only/idempotent/non-destructive, and the description adds genuinely non-obvious context: free callers get a sample rather than the full route set, the full set requires a paid key, and the tool is gated so the agent must surface a human_url to its operator. The return-field list (carrier, type, fiber count, lit capacity, distance) is somewhat redundant with the existing output schema, which keeps this from a 5.

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

Conciseness4/5

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

Front-loaded with the trigger condition, then access limits, then parameters, then the sibling redirect — good ordering. Slight redundancy in repeating the filter fields ('Filter by carrier, route_type, market' followed later by 'Filter by market ... or carrier') keeps it from a 5.

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

Completeness4/5

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

An output schema exists so return values needn't be explained, yet the description still summarizes them; combined with the free/paid access disclosure and the gating instruction, an agent has what it needs to call this correctly. Minor gaps remain around result limits, pagination, and how multiple filters compose.

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

Parameters3/5

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

Schema description coverage is 100%, so all four parameters are already documented in detail, including route_type values and market slug examples. The description only restates the filterable fields and adds the useful note that market accepts a slug from rank_markets; it does not clarify whether market and carrier are combined with AND or how include_sources affects shape. Baseline 3 is appropriate.

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?

States a specific verb and resource (retrieve fiber routes/carriers/connectivity for a market) and enumerates the route classes it covers: long-haul, metro, dark, IX. It also distinguishes itself from the nearest sibling by saying 'For one building use get_facility,' so an agent can route without opening either schema.

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

Usage Guidelines5/5

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

Gives an explicit trigger ('when the user asks about fiber routes, carriers or connectivity for a market'), explicit filter combinations, a named alternative for the building-level case, and even an example query ('Zayo long-haul routes via Dallas'). The pointer to rank_markets for the market slug is actionable routing guidance.

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