Struct HookOutcome 

pub struct HookOutcome {
    pub block: bool,
    pub reason: Option<String>,
    pub override_content: Option<String>,
}

Outcome of a hook invocation.

block corresponds to exit code 2. The semantic of “block” depends on the event:

• PreToolUse → block the tool call (BeforeToolCallResult { block: true })
• Stop → block the stop (agent continues running)
• Other events → block has no effect (notification only)

Fields

block: bool

Exit code 2 from a script → true. See struct doc for semantics.

reason: Option<String>

Human-readable reason (maps to reason in BeforeToolCallResult).

override_content: Option<String>

PostToolUse only: override the tool’s result content.
