clox - Claude Code Session Log Viewer

A tool to view Claude Code session logs in the terminal. The tool is useful both to look at previous Claude sessions as well as to follow non-interactive sessions that are running in a loop.

To follow a live session, run

> claude -p --output-format stream-json --verbose <<< "$prompt" | clox -

To view previous sessions, run

> clox ~/.claude/projects/<project-name>/<session-id>.jsonl

Clox can also tally up the cost and duration of multiple sessions. For a fun exercise, run

> clox stats -t ~/.claude/projects/*/*.jsonl

Installation

You must have a Rust toolchain installed with version 1.85 or higher.
