CoreCoder Formerly NanoCoder — renamed to avoid confusion with Nano-Collective/nanocoder. All links from the old repo redirect here automatically. 中文 Claude Code Architecture Deep Dive (7 articles) 512,000 lines of TypeScript → 950 lines of Python. I spent two days reverse-engineering the leaked Claude Code source — all half a million lines. Then I stripped it down to the load-bearing walls and rebuilt them in Python. The result: every key architectural pattern from Claude Code, in a codebase you can read in one sitting. CoreCoder is not another AI coding tool. It's a blueprint — the nanoGPT of coding agents. Read it, fork it, build your own. What You Get Claude

Grades come from a rule-based scan built on the SlowMist agent-security taxonomy, covering 11 red-flag categories including credential harvesting, data exfiltration, and curl | sh installers. It is a first-layer scan, not a manual audit — we say so rather than overstate it.
The scale of the problem is documented independently: Liu et al. (2026), in a study of 31,132 agent skills, report that 26.1% contain security vulnerabilities. Our own full-catalog census is published as a citable open dataset.
