DC Hub Intelligence

Fiber Intelligence

get_fiber_intel

Read-onlyIdempotent

Map fiber routes and carriers for a metro or site, filtering by carrier, route type, and market to return GeoJSON route details like fiber count, capacity, and distance.

Instructions

Use this whenever the user asks about fiber routes, carriers or connectivity for a site or market. Call when the user asks which fiber routes or carriers serve a metro, or wants long-haul, metro, dark or IX routes mapped. 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."

Input Schema

TableJSON Schema

Name	Required	Description
`market`	No	Metro 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.
`carrier`	No	Fiber carrier to filter on, e.g. Zayo, Lumen, Cogent, "Crown Castle", Windstream, GTT, Uniti; omit for all carriers
`route_type`	No	Route class: "metro", "longhaul", "dark", or "ix"
`include_sources`	No	Include upstream data-source/provenance metadata in the response

Output Schema

TableJSON Schema

Name	Required	Description
`type`	No	"FeatureCollection" — the payload is GeoJSON, ready for Leaflet/Mapbox
`quota`	No	Caller quota state (remaining calls, tier) when available.
`total`	No	Total routes matching the filter (null when withheld by tier)
`_entity`	No	Payload class discriminator (e.g. facility\|market\|iso_grid\|queue_results\|deal\|report\|response) — branch on this before parsing the rest.
`citation`	No	Machine-readable citation: how to attribute DC Hub (dchub.cloud) for this payload. Normally an OBJECT {source, url, license, cite_as, retrieved_at}; a bare string is accepted and carries the attribution line itself.
`features`	No	Fiber route features
`provenance`	No	Collection-level provenance block: {source, method, as_of, verification_counts, cite_url_template, license, cite_as}. Quote the verification level when citing.
`_front_door`	No	In-band front-door hint (first workflow-entry tool of a session): call plan_query(intent) first for the ordered multi-step plan.
`_return_loop`	No	Suggested next-session delta call (get_changes since=24h) so you pull only what changed.
`site_evaluation_handoff`	No	Pre-built follow-up calls (analyze_site / get_water_risk args) when the payload carries coordinates — an array of {tool, parameters, why} entries.

A3.9/5.0

Behavior4/5

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

Annotations already declare readOnly, idempotent, non-destructive, and closed-world, so the safety profile is covered. The description adds genuinely non-structured behavior: free callers receive only a sample of routes while the full set requires a paid key — critical for interpreting results, though no rate limits or pagination are mentioned.

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?

The use-case and scope constraint are front-loaded in the first two sentences, followed by filters, return shape, and gating in a compact block. Minor redundancy: listing returned fields (carrier, type, fiber count, etc.) duplicates the output schema.

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?

With a full output schema, 100% parameter coverage, and annotations covering the safety profile, the description only needs to supply routing and behavioral context. It does that (triggers, example, free-vs-paid gating); the sole gap is sibling disambiguation against other fiber tools.

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%, and each parameter already carries examples and semantics (market slug, carrier names, route_type values). The description only restates the filter field names ("Filter by carrier, route_type, market") without adding syntax or constraints, so the schema does the heavy lifting.

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

Purpose4/5

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

The description names a specific resource set (fiber routes, carriers, connectivity) and scope (site or market), plus the route classes it returns (metro, long-haul, dark, IX). It is clear on its own but never distinguishes itself from overlapping siblings such as get_metro_fiber, get_fiber_readiness, or get_subsea_cables, which an agent must disambiguate.

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?

It gives concrete trigger conditions ("whenever the user asks about fiber routes, carriers or connectivity"; "wants long-haul, metro, dark or IX routes mapped") and a worked example. That is strong positive guidance, but it never states when NOT to use it or which sibling to prefer for adjacent questions like fiber readiness or metro-specific fiber.

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