Weekly Productivity Metrics

Generate a comprehensive weekly report analyzing development activity, task throughput, and AI collaboration patterns — with actionable workflow optimization proposals.

Data Collection

Run all git commands and task CLI commands from the project root. Collect data in parallel where possible (git stats + task stats are independent).

1. Git Commit Analytics

# Total commits (last 7 days)
git log --oneline --since="7 days ago" | wc -l

# Commits with full metadata (hash, author, date, subject)
git log --format="%H|%an|%ai|%s" --since="7 days ago"

# Lines changed (insertions/deletions)
git diff --stat $(git log --since="7 days ago" --reverse --format="%H" | head -1)^..HEAD 2>/dev/null || git diff --stat --shortstat HEAD~50..HEAD

# Per-commit stats (files, insertions, deletions)
git log --since="7 days ago" --format="%H|%s" --numstat

# Files touched (unique)
git log --since="7 days ago" --name-only --format="" | sort -u | wc -l

# Commits by hour (for peak hours analysis)
git log --since="7 days ago" --format="%ai" | cut -d' ' -f2 | cut -d: -f1 | sort | uniq -c | sort -rn

# Commits by day of week
git log --since="7 days ago" --format="%ad" --date=format:"%A" | sort | uniq -c | sort -rn

# Commits by conventional-commit type
git log --since="7 days ago" --format="%s" | grep -oE "^[a-z]+\(" | tr -d '(' | sort | uniq -c | sort -rn

# Commits by scope
git log --since="7 days ago" --format="%s" | grep -oE "\([^)]+\)" | tr -d '()' | sort | uniq -c | sort -rn

# AI co-authored commits (Claude collaboration indicator)
git log --since="7 days ago" --format="%H %s%n%b" | grep -c "Co-Authored-By.*Claude\|Co-Authored-By.*claude\|Co-authored-by.*Claude"

2. TaskNotes Analytics

# Sprint summary
pnpm task:sprint 2>/dev/null

# Full sprint task list (JSON for parsing)
pnpm task:list --sprint -f json 2>/dev/null

# All tasks (including non-sprint)
pnpm task:list -f json -a 2>/dev/null

# Time tracking for the week
pnpm task:time --week 2>/dev/null
