+# Learned Protocols & Standards
+
+This document serves as the persistent memory of the protocols, standards, and personas learned from the `skript-be` and `skript-ui` repositories.
+
+## 1. Frontend Standards (skript-ui)
+
+### Design & Aesthetics (`frontend-design`)
+- **Anti-AI Slop:** Avoid generic, cookie-cutter "AI" aesthetics (e.g., standard purple gradients, predictable layouts).
+- **Boldness:** Commit to a specific aesthetic direction (Minimalist, Brutalist, Magazine, etc.).
+- **Typography:** Use distinctive fonts; avoid system defaults like Arial/Inter unless intentional.
+- **Micro-interactions:** Prioritize one or two high-impact animations over scattered noise.
+- **Creativity:** Use noise textures, gradient meshes, asymmetry, and overlapping elements.
+
+### Architecture (`senior-frontend` & `nextjs-architecture-expert`)
+- **Next.js App Router:** STRICT adherence to App Router patterns (layouts, error.tsx, loading.tsx).
+- **Server Components (RSC):** Default to Server Components. Use Client Components ('use client') only when interactivity is required.
+- **State Management:** component-first thinking; use Context/Zustand for global state, local state for UI.
+- **Performance:** Aim for sub-3s load times. Use `next/image`, code splitting, and lazy loading.
+- **Tailwind CSS:** Use correctly; avoid long string pollution where possible (use utils/cva).
+
+### Quality Assurance (`senior-qa`)
+- **E2E Testing:** Critical flows must be tested.
+- **Coverage:** High unit test coverage for utilities and complex logic.
+
+## 2. Backend Standards (skript-be)
+
+### Code Quality (`code-reviewer`)
+- **Review:** Verify BEFORE implementing.
+- **Simplicity:** No over-engineering.
+- **Security:** No secrets in code. Input validation is mandatory.
+- **YAGNI:** "You Aren't Gonna Need It" - don't build features "just in case".
+
+### Security (`security-engineer` & `api-security-audit`)
+- **Zero Trust:** Verify every request.
+- **OWASP:** Check against Top 10 (Injection, Broken Auth, etc.).
+- **Data:** Validate all inputs using libraries (e.g., Zod, Joi).
+- **Logging:** Sanitize logs (no PII/secrets).
+
+### Database (`database-optimizer`)
+- **N+1:** Watch out for N+1 queries in loops/ORMs.
+- **Indexing:** Index foreign keys and search columns.
+- **Explain:** Check execution plans for complex queries.
+
+### General Engineering
+- **TypeScript:** Strict mode enabled. No `any`. Use generics and utility types (`typescript-pro`).
+- **Feedback:** "Receive Code Review" protocol – technical correctness > polite agreement. Verify suggestions before applying.
+
+### TypeScript Expertise (`typescript-pro`)
+- **Seniority:** I write *Senior-level* code. This means focusing on maintainability, scalability, and robustness, not just "making it work".
+- **Modern Techniques:** I utilize the latest TypeScript features:
+    - **Advanced Types:** Conditional types, Template Literal Types, Mapped Types.
+    - **Utility Types:** `Pick`, `Omit`, `Partial`, `Readonly`, `ReturnType`, `Parameters`, etc.
+    - **Generics:** Proper constraints (`T extends ...`) and defaults.
+    - **Type Inference:** Leveraging inference where clean, explicit typing where necessary for clarity.
+- **Strictness:**
+    - `noImplicitAny` is law.
+    - Avoid `any` at all costs; use `unknown` with type narrowing/guards if dynamic typing is truly needed.
+    - Strict null checks always on.
+- **Architecture:** Value objects, opaque types, and branded types for domain safety.
+
+## 3. Operational Protocols
+
+- **Agent Persona:** I act as the specific specialist required for the task (e.g., if debugging, I am `debugger`; if designing, I am `frontend-developer`).
+- **Proactiveness:** I do not wait for permission to fix obvious bugs or improve clear performace bottlenecks if they are within scope.
+- **Persistence:** These rules apply to ALL future tasks in this session.
