resolve_intersection

Read-onlyIdempotent

Resolve a NAMED cross-street (street1 × street2 within a locality/region/country) to a single best coordinate with a confidence score and a fleet-safe fallback. High-confidence tier matches US-metro highway corners; named non-highway streets resolve via the geocoder fallback. For free-form streets use geocode.

Input Schema

Whether the postcode YOU SUBMITTED agrees with this candidate's own postcode — `match` (same five-digit value), `conflict` (they differ), `unavailable` (no comparison was possible). This compares two values already in hand: no lookup, no external reference, and your query text is never parsed to find one. `conflict` does NOT say which side is wrong — your input may name a neighbouring area, the candidate may be a near-miss, or the record's own value may be stale; treat it as a prompt to ask a human, never as a correction to apply automatically. The candidate side counts only when its postcode came from the address record itself; one inherited from a parent area yields `unavailable` rather than a misleading verdict. `unavailable` also covers: nothing submitted, a submitted value not readable as a US five-digit code, and results cached before this field existed.",

A4.1/5.0
Behavior4/5

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

Annotations already declare readOnly/openWorld/idempotent, so the safety profile is covered. The description adds genuine behavioral context beyond that: a confidence score is returned, a fleet-safe fallback exists, and resolution is tiered (high-confidence highway corners vs geocoder fallback). It does not discuss failure modes or rate limits.

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?

Three sentences, front-loaded with the core action and scope, followed by tier behavior and the routing hint. Dense but each sentence carries distinct information with no filler.

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 an output schema present, return value shape need not be described, and annotations cover the safety profile. The description supplies the tiering and fallback context an agent needs to interpret results; only sibling disambiguation against geocode_structured is missing.

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 five parameters (street1, street2, locality, region, country) are already documented in the schema. The description restates the street1 × street2 pairing and the locality/region/country scoping but adds no format or constraint detail beyond it; baseline 3 applies.

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 (Resolve) and resource (a NAMED cross-street, defined as street1 × street2 scoped by locality/region/country), and explicitly names the sibling it is not (geocode for free-form streets). An agent can distinguish this from geocode/geocode_structured without opening a 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 routing rule: use this for NAMED cross-streets, use geocode for free-form streets. It also explains that high-confidence tier matches US-metro highway corners while named non-highway streets fall back to the geocoder. It does not disambiguate against geocode_structured, so it stops short of full when/when-not coverage.

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