## TL;DR
The Kount RIS response arrives with fields the agent does not recognize, or the agent reads the wrong field for the decision. Fix: pin the RIS version you code against, map response fields to your internal enums explicitly, ignore unknown fields, and keep recorded fixtures for regression tests. Schema drift should break a test, not a production run.

fraud agent unable to read kount ris response schema
```

## Use this when
- The agent throws on RIS responses or misreads the decision.
- A Kount schema update coincides with the first failures.
- New response fields appear that your parser does not expect.

## Not for this skill when
- RIS times out or returns errors. That is availability, not schema.
- Authentication to RIS fails. That is a credentials problem.

## Steps
1. Capture a full raw RIS response and diff it against your parser's expectations. Verify: the diff names the unexpected or missing field.
2. Pin the RIS API version in your requests and code against that version's schema only. Verify: the version string lives in config, not hardcoded in five places.
3. Map response fields to internal enums explicitly: decision codes to approve, review, or decline, and scores to your bands. Verify: every documented code has a mapping, with a default for unknown codes.
4. Parse tolerantly: unknown fields are ignored and missing optional fields get defaults. Verify: a response with extra fields parses cleanly.
5. Store recorded fixtures with sensitive values stripped and run them in CI. Verify: a schema change fails the fixture test before deploy.

## Variant phrasings
### kount ris schema parse error
Common phrasing.
### agent cannot read kount response
Agent-focused search.
### kount response fields unknown
Field-focused phrasing.

Compatibility: Kount RIS; the version-pinning and fixture pattern applies to any risk vendor response.

## Why it happens
Kount extends its response schema over time, and parsers written against a snapshot choke on new fields or miss renamed ones. The decision field is also easy to misread when you guess at mappings instead of writing them down.

## Edge cases / pitfalls
- Strip PANs, device ids, and personal identifiers from fixtures before storing them.
- Unknown decision codes must map to review, never to silent approve.
- Version upgrades need a deliberate migration: new fixtures, updated mappings, staged rollout.
