ccunpacked.dev

Description

ccunpacked.dev is a community-built visual reference website for the leaked Claude Code codebase, launched within 24 hours of the leak. It provides interactive architecture diagrams, a comprehensive tool catalog, command reference, and feature flag mapping. The site has become the canonical community navigation layer for understanding Claude Code's 512K-line codebase and its internal architecture.

Content Inventory

Section Scope
Architecture explorer Interactive diagram with color-coded tiles of the five-layer-architecture, with clickable subsystem navigation
Agent loop diagram 11-step visualization of the core agent loop from user input through tool execution and response
Tools catalog Documentation of 40+ tools including their parameters, permissions, and behavior
Commands reference Coverage of 73+ CLI commands including undocumented and internal commands
Hidden features Catalog of features not mentioned in official documentation, such as buddy-sprite, undercover-mode, and operon-desktop-mode
Feature flags Mapping of 108 feature flags, significantly more than the 44 widely cited in earlier analyses

Feature Flag Discovery

One of ccunpacked.dev's most significant contributions is the comprehensive mapping of 108 feature flags, more than double the 44 flags that were initially documented by other community analyses. This mapping covers the full tengu_ namespace used by growthbook and includes flags for unreleased features, A/B experiments, and internal debugging toggles that are not visible in normal usage. The site categorizes each flag by function (kill switch, experiment, analytics, etc.) and tracks when flags were added or removed across versions.

Relationship to Other Community Tools

ccunpacked.dev draws on data from several community sources:

Community Impact

The site serves multiple audiences: developers building on Claude Code who need to understand undocumented behavior, security researchers examining the permission-pipeline and bash-security implementations, and the broader AI community interested in how a production agentic coding tool is architected. Its 11-step agent loop diagram has been widely cited in blog posts and conference talks about agentic AI architecture.
