[JusterZhu]

🎯 Goal

Transform the GeneralUpdate Skill CodeGen from a documentation-driven reference into an automated development toolkit, inspired by ui-ux-pro-max-skill architecture patterns.

✅ Deliverables

P0 — Automation Tools

• BM25 search engine (Python) — 50+ known issues database, natural language query, 15 tests passing
• Parameterized code generator (Python) — 336 combinations (6 strategies × 7 frameworks × 2 Bowl × 4 scenes)
• CLI skeleton (TypeScript) — 5 commands (init/uninstall/generate/versions/update), 10 AI platform configs
• CI/CD — CI workflow (Python/.NET/TypeScript validation) + Release workflow

P1 — Developer Experience

• Root SKILL.md: developer roadmap, 5-question decision tree, 8 anti-patterns
• All 5 sub-skill SKILL.md: narrative workflow, requirements extraction, pre-delivery checklist, anti-pattern table
• Structured output format with decision reasons + warnings + checklist
• CLAUDE.md: AI agent development guide

P2 — Extension Skills

• generalupdate-migration: v9.x → v10 / dev-branch → stable migration path
• generalupdate-security-audit: 14-point security audit matrix

P3 — Quality Assurance

• Comprehensive audit: 32/32 readiness checks passed
• 4 critical bugs fixed (CLI 1-skill install, uninstall scope, Dispatcher, WinForms this, MAUI using, placeholder leak)
• Sync tool (_sync_all.py) and architecture docs
