Struct FailureReport 

pub struct FailureReport {
    pub failing_sub_goal: String,
    pub failing_step: String,
    pub attempts: Vec<String>,
}

Structured explanation for why the agent stopped before success.

Always surfaced verbatim to the caller — the CLI prints it, the eval harness matches on it, the MCP response includes it. No lossy formatting.

Fields

failing_sub_goal: String

Natural-language purpose of the sub-goal that was active when we gave up. Matches SubGoal.purpose exactly.

failing_step: String

Natural-language purpose of the specific step that exhausted its retry budget. Matches Step.purpose exactly.

attempts: Vec<String>

Error messages from each attempt, oldest first. Capped at the configured step-retry budget (default 3). Each entry is the StepResult::Err { message } from one attempt.
