# test-strategy

## Registry Trigger

**Use when**

- choose risk based proof portfolio test levels failure mechanisms oracles omissions and admissibility evidence

**Do not use when**

- one test level and command are already fixed or the task only implements tests or decides release readiness

## Skill Role

Select the smallest proof portfolio from mechanisms, consequences, surfaces, oracles, levels, omissions, and limits; exclude exact commands, cases, validation judgments, and release verdicts.

## High-Value Rules

- Map each risk to its mechanism, consequence, surface, oracle, and cheapest exercising level.
- Define mechanism-sensitive assertions and signals without taking entrypoint, coverage, or fallback ownership from `targeted-validation-selection`.
- Route release evidence to `delivery-release-gate`.

## Anti-Patterns

- Local success substituted for evidence of the test strategy contract.

## Stop Conditions

Stop on unresolved acceptance, consequence, surface, environment/fixture, oracle, or high-risk evidence owner. Repository checks prove only inspected paths and environments.

## Output Contract

- risk based test strategy decision with failure mechanisms oracles proof levels coverage obligations omissions command-signal requirements and admissibility limits
