Built a reusable Claude Code project template that wires Jake's three-layer routing system into a full session architecture.
The template integrates three frameworks: Van Clief's routing (the structural backbone), Karpathy's behavioral rules (think before acting, minimum viable scope, surgical changes, goal-driven execution), and IBE intent preservation (the "why" behind every decision). Each tier has a clear job — CLAUDE.md routes, workspace context files carry domain knowledge, skills wire selectively per task. The core addition on top of Jake's routing: a session state pattern (STATE.md) that eliminates cold-start friction. Each session closes by setting the next session's intent. Work becomes a directed sequence rather than a series of isolated conversations. Results from two validations (a meta-framework design project and a non-software operational coordination project): - Zero context re-establishment at session start - Zero intent-misaligned rework - Second project stood up in ~25 min on first attempt, no structural modifications needed Template is public: https://gitlab.com/vigilkeep/ibe-workflow-template Happy to share the ADR that documents the one deliberate deviation from 3.3 guidance (CLAUDE.md runs ~70 lines instead of 40–50 — there's a specific reason).
