Summary

An interactive, fully static, bilingual (EN/ZH) documentation site covering Claude Code CLI internals, built from source analysis of v2.1.88 (live at cc.clawlabz.xyz). Turns the raw analyses into navigable technical documentation pages per subsystem.

Key Takeaways

  • Navigable per-subsystem docs beat raw source dumps for learning
  • English pages make it the most accessible Tier 1 entry point
  • Good model for documenting your own harness

Reliability Note

Independent reverse-engineering effort - unofficial, verify against official Anthropic docs and behavior.
