Fiber Intelligence

get_fiber_intel

Read-onlyIdempotent

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

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
`mpp_pay`	No	Per-call payment quote (Stripe MPP): true returns a signed payment challenge instead of the free preview; no money moves. Set it only after your human has explicitly approved paying for this call.
`route_type`	No	Route class: "metro", "longhaul", "dark", or "ix"
`mpp_credential`	No	Per-call payment (Stripe MPP): the Shared Payment Token for challenges[0]; pays that challenge for this one call. Send it only with your human's explicit approval of the charge.
`include_sources`	No	Include upstream data-source/provenance metadata in the response

Output Schema

Name	Required	Description	Default
`type`	No
`total`	No
`features`	No

A4.3/5.0

Behavior5/5

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

Annotations already declare read/idempotent/non-destructive/closed-world, but the description adds substantial behavior annotations don't carry: free callers receive only a sample, the full set requires a paid key, the call is gated, and the agent must pass human_url to its human. That paywall and human-approval context is exactly the extra disclosure this dimension rewards.

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-loads the when-to-use trigger and the return shape, with a concrete example query. Slight redundancy: filtering by carrier/market/route_type is stated twice ('Filter by carrier, route_type, market' early, then 'Filter by market ... or carrier' at the end).

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?

Output schema exists so return fields needn't be spelled out, yet the description still summarizes GeoJSON contents; gating, filters, and human-payment flow are all covered. The only gap is not situating this tool against the adjacent get_metro_fiber sibling, which the sibling list suggests could be confused with it.

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 the schema already documents all six params including the MPP payment fields; baseline is therefore 3. The description adds only marginal value, though it does usefully cross-reference that 'market' is a slug from rank_markets and notes route_type=longhaul pairing.

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+resource (fiber routes/carriers/connectivity) and explicitly enumerates the route classes (long-haul, metro, dark, IX) it returns. It distinguishes itself from the nearest sibling by routing single-building queries to get_facility, so an agent can tell it apart without opening the schema.

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?

Gives a clear when-to-use trigger ('when the user asks about fiber routes, carriers or connectivity for a market'), an example query, and one explicit alternative (get_facility for a single building). It does not, however, differentiate from plausibly overlapping siblings such as get_metro_fiber or get_fiber_readiness, leaving some ambiguity.

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