Summary

• Adds cc-toolkit to the Development & Code Tools category.
• Includes cc-toolkit/SKILL.md following the contribution template.

What problem it solves

Claude Code users lack visibility into their own usage patterns — session time, AI autonomy ratio, burnout risk, estimated API costs, and context window usage. cc-toolkit provides 35+ zero-dependency CLI tools (all runnable via npx) that answer these questions instantly, with no configuration and no data leaving the local machine.

Who uses this workflow

Developers and teams using Claude Code who want to understand, monitor, and optimize their AI-assisted development workflow.

How it's used

npx cc-session-stats    # Hours, active days, streaks
npx cc-agent-load       # You vs AI time split
npx cc-burnout          # Burnout risk score
npx cc-cost-check       # Estimated API cost

Browser-based tools are also available at yurukusa.github.io/cc-toolkit.
