Zinvyl Marketplace Agent Gateway

Prepare an authorized funding route

prepare_purchase_route
Read-onlyIdempotent

Compatibility inspection alias for existing clients; new integrations should use get_purchase_requirements and buy_service. Use only after selecting an offer and confirming explicit purchasing authority. Returns the purchase-intent schema and payment-route API endpoint; it does not create, fund, verify, or start an order.

Input Schema

NameRequiredDescriptionDefault
offer_idYesExact published offer ID returned by qualify_task or list_offers, including zinvyl.freight.workflow-audit.v1, zinvyl.freight.full-workflow-audit.v1, zinvyl.api.failure-triage.v1, and zinvyl.api.workflow-failure-rescue.v1.
human_authorized_to_fundYesTrue only when an authorized representative approved the request or an authorized purchasing agent is acting within explicit delegated authority for this offer, amount, and material limits.

  16. First observed

TDQS

A4.2/5.0
Behavior4/5

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

Annotations already declare readOnlyHint=true, idempotentHint=true, destructiveHint=false, and the description is fully consistent, reinforcing that nothing is created, funded, verified, or started. It adds useful precondition context (authority confirmation) beyond the annotations. It stops short of describing what the returned schema/endpoint actually look like or any auth requirements for the route.

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 compact sentences, each carrying distinct information: identity/migration path, prerequisites, and return/negation scope. Front-loaded with the compatibility-alias framing so a reader immediately knows its status, though the leading clause is dense.

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?

No output schema exists, and the description explicitly characterizes the return (purchase-intent schema plus a payment-route API endpoint). For a read-only compatibility shim in a multi-step purchasing flow, it covers purpose, prerequisites, migration guidance, and negative space — nothing an agent needs to call it correctly 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% and both parameters carry detailed descriptions, so the schema already does the heavy lifting. The description adds only the indirect hint that an offer must be selected first and purchasing authority confirmed, which loosely maps to offer_id and human_authorized_to_fund but adds no new semantics.

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?

States precisely that this is a compatibility inspection alias that returns the purchase-intent schema and payment-route API endpoint, and explicitly negates the actions it does not perform (create, fund, verify, start an order). It names the sibling tools (get_purchase_requirements, buy_service) it is not, so an agent can differentiate it. Slightly weaker than a 5 because the tool name implies a preparatory action the description then has to walk back.

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 audience rule ('existing clients' vs 'new integrations should use get_purchase_requirements and buy_service') and an explicit prerequisite ordering ('Use only after selecting an offer and confirming explicit purchasing authority'). Both when-to-use and when-to-use-something-else are covered.

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