Generate a token-usage stat card from local Claude Code, Codex, Gemini CLI, and OpenCode session logs, and commit it as an SVG file to the repository. Use when you need a current usage figure for a README or a shareable summary of coding-agent activity.

Research how real apps and websites handle a screen, flow or visual style before designing. Uses UXKIN MCP tools to search iOS screens, user journeys and website design systems, compare several examples end to end, and report the shared pattern, the differences and a recommendation.
