Preview Case (Pricing & Eligibility)

preview_case
Read-onlyIdempotent

Dry-run a collection case BEFORE creating it: returns eligibility, the assigned collection partner, pricing (success fee), and any contracts that would need signing. Nothing is persisted. ALWAYS call this before create_case and show the user the pricing and requirements.

Input Schema

currencyCodeYesISO 4217 currency code, e.g. "EUR", "USD", "DKK"
amountToRecoverNoTotal principal amount. Omit when sending claimLines

TDQS

A4.4/5.0
Behavior4/5

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

Annotations already declare readOnlyHint, idempotentHint, and destructiveHint=false. The description adds context by stating 'Nothing is persisted' and enumerates the return payload (eligibility, partner, pricing, contracts). This goes beyond the annotations and clarifies the operation's safe, consultative nature.

Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

Conciseness5/5

Is the description appropriately sized, front-loaded, and free of redundancy?

The description is two sentences, front-loaded with the core action ('Dry-run... BEFORE creating it'), followed by return values and a usage directive. No redundant wording.

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?

For a read-only tool with no output schema, the description provides a good overview of the returned information and a clear call-to-action. It does not detail error cases or edge conditions, but given the annotations and schema richness, it is sufficiently complete for agent 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 100%, so the schema fully documents all 10 parameters. The description does not add additional parameter-specific semantics beyond noting that pricing and eligibility are computed from the input, but this is implied rather than explicit. Baseline of 3 is appropriate.

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?

The description clearly states the action ('Dry-run a collection case'), the object (collection case), and the purpose (before creating it). It distinguishes from create_case by explicitly noting nothing is persisted, and lists the return values (eligibility, partner, pricing, contracts), making it distinct from get_case.

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?

The instruction 'ALWAYS call this before create_case' provides explicit usage context and an alternative (create_case). It also tells the agent to show the user the pricing and requirements, which is a clear workflow directive.

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