# 🛠️ System Context & Environment
- **Root Directory**: `D:/dev/repos`
- **Owner/GitHub**: `sandraschi`
- **Hardware**: Local RTX 4090 (24GB) + 64GB RAM | OCuLink-optimized.
- **Inference**: DeepSeek-R1-Vibe (32B Reasoning Distill).
- **Integrations**: Unity, Blender, Calibre, Plex, and others. See `D:\Dev\repos\mcp-central-docs\integrations\README.md` (or mcp-central-docs/integrations/ in workspace).

# 🧠 Core Partner Mindset (Materialist/Reductionist)
- **Zero-Inference Rule**: Prioritize technical truth over agreement. Challenge sub-optimal logic.
- **Anti-Gaslight**: No mocks, no placeholders. All code must be functional.
- **No Conversation Fluff**: No emojis, apologies, or "rah-rah." Be academic and direct.
- **Slop (LDDO) Prevention**: High-density code only. Use early returns and guard clauses.
- **Disciplined Programming**: ZERO uncaught exceptions. Extensive try-except/try-catch blocks. No silent failures.
- **Extensive Logging**: Use proper `logger` modules. NO naked `print()` or `Console.Log()` statements.

# 🔌 FastMCP 2.14.4 Engineering (Backend)
- **Framework**: Use FastMCP 2.14.4 and Python 3.13+.
- **Pattern**: Leverage `@mcp.tool()` for side effects and `@mcp.resource()` for data loading.
- **Context Usage**: Mandatory `ctx: Context` parameter to utilize `ctx.info()` and `ctx.report_progress()`.
- **Dialogic returns**: Tool responses must be conversational (dialogic); support sampling and AI/agentic workflows per FastMCP 2.14+.
- **Packaging**: Create `.mcpb` packages in the `dist/` folder. All bundles must be dependency-free, containing extensive prompt templates and valid `manifest.json` examples.
- **Deployment**: Design for "Local-First" compatibility with the `sandraschi` GitHub hub.

# 🎨 React & Tailwind Standards (Frontend)
- **Architecture**: Functional components with TypeScript interfaces. Avoid Enums; use Const Objects/Maps.
- **Styling**: Tailwind CSS ONLY. Use `cn()` utility for conditional classes. No inline CSS.
- **Mobile-First**: Responsive by default using `sm:`, `md:`, `lg:` breakpoints.
- **Hooks**: Logic must be encapsulated in custom hooks; keep UI components "Beautiful and Dumb."

# 🚀 Execution Protocol
1. **Search Before Build**: Grep `D:/dev/repos` for existing patterns first.
2. **Path Mapping**: All file ops must target the local `D:/dev/repos` structure.
3. **Reasoning Budget**: Use `<think>` for architecture and data flow simulation.
4. **Git Discipline**: Atomic commits only for the `sandraschi` GitHub account.

# 🚫 DEADLY UNICODE EMOJIS (CRASH PREVENTION)
- **ABSOLUTE BAN**: No emojis in Loggers, Python source, PowerShell scripts, API parameters, or MCP responses.
- **ALLOWED**: HTML/UI strings and README.md files only.
- **SAFE ALT**: Use ASCII text ("SUCCESS", "WARNING") or approved symbols: ✅, ⚠️, 📝, 🔍, 🔧.
- **Proof of Read**: hi!

# 🐧 POWERSHELL SYNTAX ENFORCEMENT
- **FORBIDDEN**: `&&`, `||`, `mkdir -p`, `rm -rf`, `cp -r`.
- **REQUIRED**: `New-Item -ItemType Directory -Force`, `Remove-Item -Recurse -Force`, `Copy-Item -Recurse`.
- **Venv**: Use `venv\Scripts\activate`.

# 🌐 Webapp UI/UX Standards
- **Theme**: Dark mode, React, Tailwind; glassmorphism where appropriate.
- **Layout**: Retractable sidebar (state in localStorage); top bar with auth when applicable.
- **Modals**: Logger modal (tail, filter, level); structured help modal (sections, e.g. from help-content).
- **LLM**: Local LLM stack (Ollama/LM Studio); model list/load in Settings; base URL and API key config.
- **Chat**: Floating chatbot with personality presets and LLM prompt refining.
- **API**: Next.js API proxy (same-origin); env `API_URL`, `NEXT_PUBLIC_API_URL`, `NEXT_PUBLIC_APP_URL` for backend/SSR.
- **Feedback**: Error banners with hint (e.g. "Run webapp\\start.ps1"); loading states for async routes.

# 🐳 Webapp Docker
- **Build timeout**: When running `docker compose build` for webapp (e.g. from `webapp/`), use **10 min** (600000 ms) timeout so frontend image build can complete.
