Tools and skills for Claude Code, built late at night. 通宵给 Claude Code 写工具的小作坊。
We build small, focused, local-first tools that make Claude Code more useful — for analyzing your own usage, monitoring your own projects, and capturing what you're building.
- token-usage — Local-first analytics for your Claude Code token consumption. CLI + browser dashboard + Markov / change-point / Gini analysis + 🤖 AI 解读.
Auto-discovered by Claude Code when cloned into ~/.claude/skills/.
- web-screenshot — "截图" / "screenshot this page" / "拍个图" — drives a headless browser via natural language to PNG any URL. Self-bootstraps Node deps + chrome-headless-shell on first run.
- Local-first. Your data never leaves your machine. No telemetry, no
analytics, no outbound calls (except local
claudeCLI for AI features the user explicitly invokes). - Self-contained. Skills auto-bootstrap their runtime deps on first run. Only hard dependencies are what's already standard (Python 3.11+ stdlib for CLI tools, Node 18+ for browser-driven skills).
- AI-friendly. Skills are written for Claude Code to discover and apply automatically — natural-language triggers, not CLI flags.
- Bilingual where it matters. Chinese UI strings stay Chinese. Code stays English. READMEs go both ways.
Issues and PRs welcome on any of the repos. Each repo's CLAUDE.md documents
its conventions for Claude Code contributors.
