This article dissects Claude Code's skill system, tracing its evolution from early prompt engineering to the modern skill framework, detailing the loading pipeline, SKILL.md structure, lazy compilation, command routing, and the system's strengths and limitations.
Rspack 1.7, the final minor release of the fast front‑end bundler, enables Lazy Compilation by default, resolves long‑standing SWC plugin compatibility issues, and brings major upgrades across the Rstack ecosystem—including Rsbuild's error overlay, performance size diff, and Rspress's AI‑ready SSG‑MD documentation feature.
Rspack 1.5 introduces experimental lazy‑barrel support, a native Rust file‑watcher, browser‑ready builds, Rust‑based plugins, constant and enum inlining, type‑reexport analysis, a built‑in virtual‑module system, module‑federation runtime boosts, install‑size reductions, seal‑stage speedups, and a host of ecosystem updates such as dropping Node 16, stabilizing lazy compilation, and new releases for Rslint, Rsbuild, Rslib, Rspress, Rsdoctor, and Rstest.
Rspack 1.3 introduces circular‑dependency detection, HTTP imports, lazy‑compilation middleware, AMD module support, 25% faster code splitting, output size reductions, macOS memory optimizations, updates to the Rstack ecosystem (Rsdoctor 1.0, Rsbuild 1.3, Rslib 0.6, Rspress 2.0, Rstest), plus detailed upgrade instructions for module types and SWC plugins.
