<quick_start> Capture today's metrics:
# Quick session stats
echo "Commits: $(git log --since='today 00:00' --oneline | wc -l | tr -d ' ')"
echo "Files changed: $(git diff --stat $(git log --since='today 00:00' --format='%H' | tail -1)..HEAD 2>/dev/null | tail -1)"
Generate weekly report:
cat ~/.claude/portfolio/daily-metrics.jsonl | jq -s 'map(select(.date >= "'$(date -v-7d +%Y-%m-%d)'"))'
</quick_start>
<success_criteria>
- Daily metrics captured automatically via End Day protocol (commits, features, fixes, cost)
- Derived metrics calculated: cost-per-feature, cost-per-bug-fix, lines-per-dollar
- Weekly digest generated with project breakdown and day-by-day trends
- Executive summary ready for stakeholder review with week-over-week comparisons
- Metrics stored persistently at

Metrics Captured
Per Session (End Day auto-capture)
| Metric | Source | How |
|---|---|---|
| Commits | git log --since="today" | Count |
| Files changed | git diff --stat | Count from diff |
| Lines added/removed | git diff --stat | Parse +/- |
| Tests added | git diff --stat -- '*.test.*' | Count test files |
| PRs created | gh pr list --author @me | GitHub CLI |
| Bugs fixed | Commits matching fix: | Conventional commits |
| Features shipped | Commits matching feat: | Conventional commits |
| Cost | ~/.claude/daily-cost.json | Daily spend |
Derived Metrics
| Metric | Formula | Why It Matters |
|---|---|---|
| Cost per feature | Total cost / feat: commits | Efficiency |
| Cost per bug fix | Total cost / fix: commits | ROI on debugging |
| Lines per dollar | Lines shipped / total cost | Productivity |
| Test coverage delta | Tests added / files changed | Quality signal |
Collection
Automatic (End Day Protocol)
The workflow-orchestrator End Day protocol calls this automatically:
#!/bin/bash
# Auto-capture at end of day
DATE=$(date +%Y-%m-%d)
COMMITS=$(git log --since="today 00:00" --oneline 2>/dev/null | wc -l | tr -d ' ')
FEATS=$(git log --since="today 00:00" --oneline --grep="^feat" 2>/dev/null | wc -l | tr -d ' ')
FIXES=$(git log --since="today 00:00" --oneline --grep="^fix" 2>/dev/null | wc -l | tr -d ' ')
COST=$(cat ~/.claude/daily-cost.json 2>/dev/null | jq '.spent // 0')
mkdir -p ~/.claude/portfolio
echo "{\"date\":\"$DATE\",\"commits\":$COMMITS,\"features\":$FEATS,\"fixes\":$FIXES,\"cost\":$COST}" >> ~/.claude/portfolio/daily-metrics.jsonl
Manual (On-Demand)
# Full session capture with git stats
STAT=$(git diff --stat $(git log --since="today 00:00" --format="%H" | tail -1)..HEAD 2>/dev/null | tail -1)
ADDED=$(echo "$STAT" | grep -oE '[0-9]+ insertion' | grep -oE '[0-9]+' || echo 0)
REMOVED=$(echo "$STAT" | grep -oE '[0-9]+ deletion' | grep -oE '[0-9]+' || echo 0)
echo "Today: +$ADDED/-$REMOVED lines, $COMMITS commits ($FEATS features, $FIXES fixes)"

Emit Outcome Sidecar
As the final step, write to ~/.claude/skill-analytics/last-outcome-portfolio-artifact.json:
{"ts":"[UTC ISO8601]","skill":"portfolio-artifact","version":"1.0.0","variant":"default",
"status":"[success|partial|error]","runtime_ms":[estimated ms from start],
"metrics":{"metrics_captured":[n],"artifacts_generated":[n],"reports_created":[n]},
"error":null,"session_id":"[YYYY-MM-DD]"}
Use status "partial" if some stages failed but results were produced. Use "error" only if no output was generated.
