A token-efficient AI engineering system for Claude Code providing structured workflows, agentic patterns, three-layer context optimization (don't-load, compress, cache), path-scoped rules, output compression via Headroom, and supply-chain security hardening for software development teams. This release (v4.4.0) adds: session startup token floor documentation, three-layer token optimization model, Headroom integration (47–92% dynamic context reduction), path-scoped .claude/rules/ pattern (41% rule overhead reduction), Mini Shai-Hulud supply chain worm security hardening, and a .claudeignore template.
