Logbook — Time Report

Generate time-per-project reports from Claude Code session logs. Groups branches under their parent project. Excludes idle gaps > 15 minutes.

Workflow

Step 1: Run the analysis script

The script lives at the plugin path. Find it relative to this skill:

SCRIPT="$(dirname "$(dirname "$(dirname "$0")")")/scripts/logbook.py"

But in practice, run it from the project root:

python3 plugins/logbook/scripts/logbook.py time --out docs/reports

This generates:

• One file per calendar month: YYYYMM-logbook-time.md
• One file per year: YYYY-logbook-time.md

To limit to a specific period:

python3 plugins/logbook/scripts/logbook.py time --year 2026 --month 3 --out docs/reports

For preview only (no files written):

python3 plugins/logbook/scripts/logbook.py time --preview

Step 2: Show the preview

After running the script, display the top 10 table from stdout directly to the user. This is the inline preview — do NOT hide it behind a file path.

Step 3: List generated files

Show the user which report files were created and their paths.

Report Structure

Each report contains:

1. Summary — total active time, project count, session count
2. Top 10 table — project name + time
3. Detailed breakdown — every project with branch-level rows showing time and session counts

Notes

• Gaps > 15 minutes between messages are excluded (configurable in script as GAP_THRESHOLD)
• Branches are detected from git worktree patterns (-git-<branch>, --claude-worktrees-<branch>)
• Excluded projects are configured in the EXCLUDED list in the script
