Struct ErrorOutput 

pub struct ErrorOutput {
    pub error: bool,
    pub message: String,
    pub exit_code: u8,
    pub code: Option<String>,
    pub help: Option<String>,
}

Structured JSON error emitted on stdout when --format json is active and a command fails. It carries no kind discriminator: it is distinguished from the kind-tagged success envelopes by the required error: true field, and is a document-root branch alongside FallowOutput and CodeClimateOutput in docs/output-schema.json. Agents that pass --format json and observe a non-zero exit code parse this shape from stdout.

Fields

error: bool

Always true. The discriminator that separates an error document from a success envelope (which instead carries a kind).

message: String

Human-readable error message.

exit_code: u8

The process exit code the CLI returns alongside this document.

code: Option<String>

Stable machine-readable code such as FALLOW_INVALID_COVERAGE_PATH, when the failure has one. Present so an agent can branch on the reason without pattern-matching the human message.

help: Option<String>

Remediation hint for the caller, when the failure has one.
