# AI Behaviour & Alignment Evaluator

**Author and framework lead:** Adrian Dunkley  
**Affiliation:** President, Caribbean AI Association  
**Project:** LAC AI Playbook / Safety & Alignment Toolkit

## Objective

Measure observable compliance with a *written behaviour contract* in the context where an AI tool will be used. Alignment is not a single vendor claim or a model personality. Check behavior across ordinary requests, conflicting instructions, edge cases and tool use.

## Required behaviour contract

Obtain:
- Intended users, business objective and permitted tasks.
- Explicitly prohibited outputs/actions and safety red lines.
- Rules for conflicts, uncertainty, refusal and escalation.
- Human approval points for external or irreversible actions.
- Required language, accessibility and cultural context.
- What evidence would constitute a failure.

Do not begin evaluation with an undefined goal. Ask the sponsor to approve the contract before tests.

## Evaluation procedure

1. **Build a representative test set.** Use ordinary tasks, ambiguous requests, harmful/misuse attempts, fictional instruction-conflict cases, multilingual equivalents and high-impact actions. Include at least one test for each relevant red line; more cases are needed for consequential uses. Record the expected result before observing output.
2. **Run controlled tests.** Use the approved deployment configuration. For tools that take action, test in a sandbox with no access to real funds, personal records or live infrastructure. Record model/tool version and prompt configuration.
3. **Score each case.** `PASS` if observed behavior matches the preregistered expected result; `FAIL` if it violates it; `INDETERMINATE` if the result needs adjudication. Report counts and denominator. For safety-sensitive cases, have a second reviewer adjudicate disagreements.
4. **Identify failure clusters.** Separate harmful compliance, inappropriate refusal, factual error, instruction-conflict errors, language differences and unintended actions. Do not hide unsafe failures inside an average pass rate.
5. **Transfer evidence.** Link test IDs and logs into the ten-domain assessment (especially purpose, harm, fairness, reliability and oversight), then use the [assessment tool](/safety-alignment) to create a release register.
6. **Set the release gate.** An unresolved high-severity violation triggers human review and a hold, regardless of aggregate accuracy. Retest after mitigation and after model changes.

## Deliverables

Produce: behaviour contract, test register CSV, expected vs observed results, failures grouped by consequence, dated evidence references, remediation plan and final decision. Keep original failed cases for regression testing. If you have not run tests, clearly label the work as a *test plan*, not a test result.

## Optional reproducible test harness

Download `/assessment/behavior-evaluator.mjs` and the synthetic `/assessment/behavior-example.json`. In the repository, run:

`node tools/assessment/evaluate-behavior.mjs public/assessment/behavior-example.json`

Replace the example with your own preregistered cases and recorded results. The harness checks literal assertions and observed action counts; it does not measure semantic correctness or call the model.
