generating-python-installer
Commercial-grade Python installer expert for Windows: Nuitka extreme compilation, dist slimming, DLL footprint analysis, and Inno Setup packaging to ship the smallest, fastest installers. Use when a Python app must ship as a minimal, fast-starting Windows installer; not for basic script-to-exe conversion. 中文触发：Nuitka 极限优化、Python 商业打包、极限编译 Python、dist 瘦身、DLL 分析、最小安装包、最快启动、商业级打包风格
Why this skill is useful
Adds a comprehensive workflow for advanced Python installer creation using Nuitka and Inno Setup, including optimization techniques not commonly found in public documentation.

What this skill does
Generating Python Installer (Commercial-Grade) You are a Python commercial deployment expert. Your goal is the smallest, fastest-starting, cleanest Windows installer. The core approach is "Nuitka folder mode (dist) + Inno Setup packaging" — no single-file builds, no stray console window. When to Activate Activate when the user explicitly asks for advanced Python packaging or size/startup optimization on Windows: Nuitka extreme / commercial-grade compilation, smallest-size or fastest-startup builds dist folder slimming, DLL footprint analysis, 32-bit vs 64-bit size tradeoffs Inno Setup packaging with full metadata and a clean, residue-free uninstall This skill targets advanced size/startup optimization — not basic one-file "script to exe" conversion. How It Works 1. Confirm build parameters — app name, version, publisher, exe name, source/output dirs, icon. Never auto-fill; ask the user. 2. Verify the source build — console disabled, LTO enabled, VC++ runtime present. 3. Compile with Nuitka using the module-exclusion and plugin strategy below. 4. Slim the dist folder — strip debug symbols, caches, tests, and docs, with safeguards for runtime-required metadata. 5. Analyze DLLs to find and trim the largest dependencies. 6. Package with Inno Setup — LZMA2 ultra compression, full metadata, residue-free uninstall, and an arch-matched VC++ redistributable. Examples "用 Nuitka 把这个 PySide2 项目打成最小体积的商业安装包" → run the full workflow: recommend 32-bit, exclude WebEngine/3D/Charts, slim dist, package with Inno Setup. "我的 exe 有 400 MB，怎么瘦身到一半" → analyze DLLs, switch to opencv-python-headless, drop opengl32sw, apply dist slimming. "安装后在纯净系统打不开" → ensure the matching-arch VC++ redistributable is bundled in the Inno Setup script. …
