OverviewDiscussionsAdmin

Recover an expired Zinvyl purchase route

recover_abandoned_purchase
Idempotent

Recovers the original transaction for the same authenticated buyer, authority policy, request ID, offer, sanitized scope, amount, currency, funding route, and current terms. Before funding it resumes an expired reservation; after verified funding it safely reissues scoped order access without charging again.

A3.6/5.0
Behavior4/5

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

The description adds real behavioral value beyond the annotations: it discloses that the tool resumes an expired reservation before funding, reissues scoped order access after verified funding, and does so "without charging again" — the single most important fact for a payment-adjacent tool. Idempotency and non-destructiveness are already covered by annotations, and it omits failure/error behavior when the prior transaction cannot be matched, which keeps it below 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?

Two sentences, no filler, with scope constraints front-loaded and the pre-funding/post-funding split placed second where it belongs. The first sentence is a long comma-run list that reads as enumeration rather than guidance, but nothing is wasted.

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

Completeness3/5

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

This is a mutating, money-adjacent, open-world tool with six parameters, nested objects, low schema coverage, and no output schema. The description covers the charge-safety guarantee well but leaves out the recovery-failure path, any authority/mandate requirement, and what the caller receives (order access token? intent id?) — gaps an agent will hit on first invocation.

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 only 17%, so the description must carry weight, and it does conceptually enumerate buyer identity, authority policy, request ID, offer, sanitized scope, amount, currency, funding route, and current terms. But it gives no format or constraint detail for previous_intent_id, continuation_token, or mandate_token, and never states that amount/offer/scope must match the original attempt or that terms must be current — the details an agent would actually get wrong.

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 a specific verb (recovers) and a concrete resource (the original transaction / expired purchase route) plus the scope constraints it must match. However, it never distinguishes itself from the near-identical sibling resume_agent_purchase or from buy_service, so an agent cannot route between them on the strength of the description alone.

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

Usage Guidelines3/5

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

"Before funding it resumes an expired reservation; after verified funding it safely reissues scoped order access" implies the two states in which the tool applies, but usage is inferred from behavior rather than stated. There is no explicit when-to-use, no guidance on choosing this over resume_agent_purchase or preflight_agent_purchase, and no statement of when recovery is not possible.

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