Struct ChainStep 

pub struct ChainStep {
    pub name: String,
    pub action: StepAction,
    pub config: Option<SlotConfig>,
    pub failure_policy: StepFailurePolicy,
    pub output_vars: HashMap<String, String>,
}

A step in a chain pipeline.

Fields

name: String

Step name (for logging and result tracking).

action: StepAction

Either an inline prompt or a skill reference.

config: Option<SlotConfig>

Per-step config overrides (model, effort, etc.).

failure_policy: StepFailurePolicy

Failure policy for this step.

output_vars: HashMap<String, String>

Extract named values from this step’s JSON output for use in later steps.

Key = variable name, Value = dot-path into the JSON output. Use "." or "" for the whole output. Use "key" for a top-level field. Use "a.b.c" for nested access. String values are returned as-is; other JSON types are serialized to their JSON representation.

Extracted values are available in subsequent step prompts as {steps.STEP_NAME.VAR_NAME}.
