Methods

createExperiment

createExperiment(
    definition: Omit<
        ExperimentDefinition,
        "status"
        | "startedAt"
        | "endedAt",
    >,
): ExperimentDefinition
Create a new experiment.
Parameters
- definition: Omit<ExperimentDefinition, "status" | "startedAt" | "endedAt">
Returns ExperimentDefinition

- Defined in packages/nexus-agents/src/learning/ab-test-tracker.ts:40

startExperiment

startExperiment(experimentId: string): void
Start an experiment (sets status to running).
Parameters
- experimentId: string
Returns void
Implementation of IAbTestTracker.startExperiment
- Defined in packages/nexus-agents/src/learning/ab-test-tracker.ts:65

pauseExperiment

pauseExperiment(experimentId: string): void
Pause a running experiment.
Parameters
- experimentId: string
Returns void

- Defined in packages/nexus-agents/src/learning/ab-test-tracker.ts:84

completeExperiment

completeExperiment(experimentId: string): void
Complete an experiment.
Parameters
- experimentId: string
Returns void

- Defined in packages/nexus-agents/src/learning/ab-test-tracker.ts:102

assignVariant

assignVariant(experimentId: string, traceId: string): ExperimentVariant | null
Assign a variant for a given trace ID (deterministic assignment). Uses consistent hashing to ensure same trace ID always gets same variant.
Parameters
- experimentId: string
- traceId: string

- Defined in packages/nexus-agents/src/learning/ab-test-tracker.ts:122

recordOutcome

recordOutcome(outcome: ExperimentOutcome): void
Record an outcome for an experiment.
Parameters
- outcome: ExperimentOutcome
Returns void

getSummary

getSummary(experimentId: string): ExperimentSummary | null
Get experiment summary with statistics.
Parameters
- experimentId: string
Returns ExperimentSummary | null

listExperiments

listExperiments(
filter?: { status?: ExperimentStatus; tags?: readonly string[] },
): readonly ExperimentDefinition[]
List all experiments.
Parameters
- Optionalfilter: { status?: ExperimentStatus; tags?: readonly string[] }
Returns readonly ExperimentDefinition[]
Implementation of IAbTestTracker.listExperiments
- Defined in packages/nexus-agents/src/learning/ab-test-tracker.ts:192

getExperiment

getExperiment(experimentId: string): ExperimentDefinition | null
Get experiment by ID.
Parameters
