Comment on: ADR-006: Extension Modularization & Install Infrastructure

### ADR-006 & Implementation Plan Review I have completed a comprehensive review of the ADR and the [Implementation Plan](https://github.com/jeremymcs/gsd-2/blob/feat/extension-system-analysis/.plans/IMPLEMENTATION-PLAN-extension-modularization.md) against the current codebase. My analysis confirms that the **177,005 LOC `gsd` monolith** and the **842 MB installation size** are critical bottlenecks that this plan accurately addresses. #### **Verification Results** - **Monolith Bloat:** Confirmed `src/resources/extensions/gsd` contains **177,005 lines of code**, verifying the urgent need for Phase 5 (Core Decomposition). - **Architectural Coupling:** Identified **15+ direct imports** from `../gsd/` in peripheral extensions (e.g., `github-sync`, `subagent`), confirming that "reverse dependencies" are a primary blocker for modularity. - **Dependency Analysis:** The root `package.json` is heavily burdened by `playwright` and multiple AI SDKs. Phase 6 (AI Provider Lazy Loading) and Phase ...
