Struct ExperimentConfig 

pub struct ExperimentConfig {
    pub enabled: bool,
    pub eval_provider: ProviderName,
    pub benchmark_file: Option<PathBuf>,
    pub max_experiments: u32,
    pub max_wall_time_secs: u64,
    pub min_improvement: f64,
    pub eval_budget_tokens: u64,
    pub auto_apply: bool,
    pub schedule: ExperimentSchedule,
    pub tolerate_subject_errors: bool,
}

Configuration for the autonomous self-experimentation engine ([experiments] TOML section).

When enabled = true, Zeph periodically runs A/B experiments on its own skill and prompt configurations to find improvements automatically.

Example (TOML)

[experiments]
enabled = false
max_experiments = 20
auto_apply = false

Fields

enabled: bool

Enable autonomous self-experimentation. Default: false.

eval_provider: ProviderName

Provider name (from [[llm.providers]]) used as the LLM-as-judge for experiment evaluation. An empty value falls back to the primary provider. Prefer a capable, low-self-judge-bias model (e.g. a different provider than the one being evaluated).

benchmark_file: Option<PathBuf>

Path to a benchmark JSONL file for evaluating experiments.

max_experiments: u32

max_wall_time_secs: u64

min_improvement: f64

eval_budget_tokens: u64

auto_apply: bool

schedule: ExperimentSchedule

tolerate_subject_errors: bool

When true, a subject call failure (LLM error or timeout) excludes the case from scoring instead of aborting the entire evaluation run.

Default: false (preserves existing abort-on-error semantics). Set to true when running parallel evaluations where a single subject timeout should not discard all already-billed responses from other in-flight futures — at the cost of producing a partial result rather than a guaranteed complete evaluation.

Implementations

impl ExperimentConfig

pub fn validate(&self) -> Result<(), String>

Validate that numeric bounds are within sane operating limits.

Errors

Returns a description string if any field is outside allowed range.
