## What logbook does, in the publisher's words

> Generated for Codex from the canonical source plugin. Run just update at the marketplace root to refresh it.

Run this workflow from Codex. Analyze Claude Code session logs to generate per-project time and message reports. Breaks down usage by project and branch, groups branches under their parent project, and produces monthly + yearly markdown reports.

> Compatibility scope: This plugin runs as a Codex skill but intentionally operates on Claude Code files, sessions, processes, or service behavior. Those source-domain references are preserved rather than relabeled as unsupported Codex runtime behavior.
