Struct ToolRunMetadata 

pub struct ToolRunMetadata {
    pub detail: ToolMetadata,
    pub line_count: Option<usize>,
    pub byte_count: Option<usize>,
    pub result_count: Option<usize>,
    pub duration_secs: Option<f64>,
    pub process: Option<ManagedProcess>,
    pub display_diff: Option<String>,
    pub diff_truncated: bool,
    pub lines_added: usize,

    pub token_usage: Option<TokenUsage>,
}

Structured metadata extracted from a completed tool run.

Fields

detail: ToolMetadata

line_count: Option<usize>

byte_count: Option<usize>

result_count: Option<usize>

duration_secs: Option<f64>

process: Option<ManagedProcess>

display_diff: Option<String>

User-facing display diff for file mutations. This is captured at tool execution time so whole-file writes can compare against the pre-write contents even after the file has been overwritten.

diff_truncated: bool

lines_added: usize

Exact line-change counts for file mutations. Carried separately from display_diff because that string is capped at MAX_DISPLAY_DIFF_LINES — recounting it would undercount large writes. handle_tool_finished folds these into the per-run totals behind the end-of-run +N/-M summary.

lines_removed: usize

artifacts: Vec<ToolArtifact>

token_usage: Option<TokenUsage>

Provider token usage the tool itself consumed (today: a subagent’s cumulative child-session usage). handle_tool_finished folds it into the parent session’s totals so the footer and the end-of-run summary count the whole tree, not just the parent’s own model calls.
