Struct PostToolUseFailureInput 

pub struct PostToolUseFailureInput {
    pub session_id: String,
    pub timestamp: i64,
    pub working_directory: PathBuf,
    pub tool_name: String,
    pub tool_args: Value,
    pub error: String,
}

Input for the postToolUseFailure hook — received after a tool execution whose result was "failure".

postToolUse only fires for successful tool executions. Register a handler for postToolUseFailure to observe failed tool calls. The CLI extracts the failure message from the tool result and passes it as the error field (rather than passing the full result object).

Fields

session_id: String

The runtime session ID of the session that triggered the hook.

timestamp: i64

Unix timestamp (ms).

working_directory: PathBuf

Working directory.

tool_name: String

Name of the tool that failed.

tool_args: Value

Arguments that were passed to the tool.

error: String

Failure message extracted from the tool’s result.
