Add ClaudeOS-Core to Tools & Utilities

[claudeos-core]

Adding ClaudeOS-Core to the 🛠️ Tools & Utilities section.

What it is

A deterministic Node.js CLI that auto-generates CLAUDE.md and .claude/rules/ from a project's actual source code. Uses a 4-pass Claude pipeline constrained by an explicit path allowlist (the LLM cannot fabricate paths that don't exist in the repo).

• npm: https://www.npmjs.com/package/claudeos-core
• License: ISC
• 12 stacks: Java/Kotlin Spring, Node (Express/NestJS/Fastify/Next.js/Vite), Python (Django/FastAPI/Flask), Vue/Nuxt, Angular
• 10 output languages
• 5 post-generation validators (claude-md-validator, content-validator, pass-json-validator, plan-validator, sync-checker)
• Monorepo-aware (Turborepo / pnpm workspaces / Lerna)

How it complements existing entries

Closest neighbor on the list is ClaudeForge (117 ⭐) — also a CLAUDE.md generator, but takes a different approach. ClaudeOS-Core's differentiator: a scanner-first architecture that extracts stack/ORM/package layout/file paths before any LLM call, then constrains generation to that explicit allowlist. Same input → byte-identical output across runs.

Also complements claude-code-auto-memory (81 ⭐) — that maintains CLAUDE.md, ClaudeOS-Core generates it from scratch.

Insertion location

After claude-code-thinking-patch (38 ⭐), before claudecode-macmenu (32 ⭐) — fits the existing star-count ordering in the unmarked tier.
