Cost Insights
Advanced cost intelligence that goes beyond simple tracking. Shows WHERE money is wasted, WHAT you got for your spend, and HOW to spend less.
Commands
/cost-insights or /cost-insights report (default)
Full insights report with all metrics:
node "${CLAUDE_SKILL_DIR}/../../scripts/insights.js" insights "${CLAUDE_SESSION_ID}"
Display the ASCII output as-is.
/cost-insights waste
Detailed waste analysis — redundant reads, failed commands, retry storms:
node "${CLAUDE_SKILL_DIR}/../../scripts/insights.js" waste "${CLAUDE_SESSION_ID}"
Explain each waste type and suggest how to avoid it.
/cost-insights roi
Cost-per-line and cost-per-commit ROI metrics:
node "${CLAUDE_SKILL_DIR}/../../scripts/insights.js" roi "${CLAUDE_SESSION_ID}"
Compare to typical benchmarks ($0.02-0.05/line is good, >$0.10/line is expensive).
/cost-insights savings
Model routing savings calculator — shows what you could save on cheaper models:
node "${CLAUDE_SKILL_DIR}/../../scripts/insights.js" savings "${CLAUDE_SESSION_ID}"
Explain which tasks could safely use Haiku vs Sonnet vs Opus.
/cost-insights anomaly
Check if this session is abnormally expensive:
node "${CLAUDE_SKILL_DIR}/../../scripts/insights.js" anomaly "${CLAUDE_SESSION_ID}"
/cost-insights badge [daily|weekly|monthly]
Generate a GitHub README badge showing AI development cost:
node "${CLAUDE_SKILL_DIR}/../../scripts/insights.js" badge monthly
Give the user the markdown to paste in their README.
Response Guidelines
- Efficiency scores: 80-100 = great, 60-79 = good, 40-59 = needs work, <40 = poor
- Always suggest actionable improvements for low scores
- For waste: explain WHY each waste happens and HOW to avoid it
- For savings: be honest that model routing requires task-type awareness
- For badges: output the markdown they can paste directly
