+# Callsign-generator
+
+##1. Syfte
+Skapa en webbaserad tj??nst som genererar CB-handles/callsigns med hj??lp av en LLM. Anv??ndaren ska kunna ge grundparametrar och eventuellt f??rfina dessa via f??ljdfr??gor innan generering.
+
+##2. M??lbild
+Tj??nsten ska:
+- generera ett realistiskt callsign baserat p?? anv??ndarens input
+- ge en kort motivering till varf??r callsignet passar
+- vara konsekvent, f??ruts??gbar och snabb att anv??nda
+- k??nnas ???dialogisk??? genom adaptiva f??ljdfr??gor
+
+##3. Anv??ndarfl??de (MVP)
+### Steg 1 - Initial input via UI
+Anv??ndaren besvarar initiala val s??som:
+- Stil (t.ex. Milit??r / Humor / Klassisk CB / Annan ??? fritext)
+- Ton (t.ex. Seri??s / Aggressiv / Lekfull)
+- Fritextbeskrivning (valfritt)
+
+### Steg 2 - Val
+Efter initiala svar finns tv?? knappar:
+```
+[ Generera ]    [ Fler fr??gor ]
+```
+
+### Steg 3A - Generera
+- Backend skickar sammanst??lld prompt till LLM
+- LLM returnerar JSON med:
+   - callsign
+   - motivering
+
+### Steg 3B - Fler fr??gor
+- Backend skickar prompt till LLM som genererar 1???3 relevanta f??ljdfr??gor
+- Anv??ndaren besvarar fr??gorna
+- Svaren lagras i state
+- Anv??ndaren kan d??refter v??lja "Generera" eller "Fler fr??gor" igen
+
+## 4. Funktionella krav
+### 4.1 Input
+- Systemet ska st??dja:
+- val via dropdown/radioknappar
+- fritext
+- ??terkommande f??ljdfr??gor
+
+### 4.2 Output
+
+Systemet ska returnera JSON i stabilt format:
+```
+{
+  "callsign": "<string>",
+  "reason": "<string>"
+}
+```
+
+### 4.3 F??ljdfr??gor
+F??ljdfr??gorna ska:
+- baseras p?? anv??ndarens tidigare svar
+- vara relevanta och korta
+- komma i 1???3 fr??gor ??t g??ngen
+- returneras som JSON:
+```
+{ "questions": [ "fr??ga 1", "fr??ga 2" ] }
+```
+
+### 4.4 State Management
+Frontend ska lagra:
+```
+answers = {
+  initial_params: {...},
+  follow_up_answers: {...}
+}
+```
+
+### 4.5 Spr??k
+MVP riktas mot svenska men ska kunna ut??kas till andra spr??k.
+
+## 5. Icke-funktionella krav
+- LLM-styrning: Stabilt via templade prompts och JSON-utdata
+- Prestanda: Svar inom < 2 sekunder f??r majoriteten av anrop (exkl. cold start)
+- Skalbarhet: Designad s?? backend kan distribueras vid behov
+- Robusthet: Systemet ska inte ???balla ur??? med l??nga poetiska svar
+- Utbyggbarhet: Framtida logotyp-/TTS-/fonetikmoduler m??jliga
+- Kostnadskontroll: Kan inf??ras via rate-limit + begr??nsad iteration
+
+## 6. Systemarkitektur
+### Frontend
+- Visar formul??r + resultat
+- Renderar f??ljdfr??gor
+- H??ller state med anv??ndarsvar
+- Anropar backend via REST/HTTPS
+
+### Backend
+- API som hanterar tv?? endpointtyper:
+```
+POST /questions
+Input: answers
+Output: JSON med f??ljdfr??gor
+
+POST /generate
+Input: answers
+Output: JSON med callsign + motivering
+```
+
+- Backend ansvarar f??r:
+    - promptkonstruktion
+    - validering
+    - OpenRouter-anrop
+    - eventuella caches
+
+### LLM (via OpenRouter)
+- Backend anropar LLM
+- LLM returnerar JSON enligt definierad struktur
+
+## 7. S??kerhets- och ??tkomstkrav
+- API-nyckel f??r OpenRouter f??r inte exponeras i frontend
+- Backend signerar samtliga anrop internt
+- M??jlighet till rate-limit per IP
+
+## 8. Implementationsteknik (rekommenderad)
+
+### Frontend:
+- SvelteKit / React / Vue (valfritt)
+
+### Backend:
+- Python (FastAPI) eller Node (Fastify)
+
+### Host-varianter:
+- docker med docker-compose
+
+### LLM:
+- OpenRouter, valfri modell (t.ex. GPT-4, Claude etc)

+# Callsign Generator
+
+En webbaserad tjänst för att generera realistiska CB-handles (callsigns) med hjälp av AI. Tjänsten använder en "dialogisk" approach där användaren kan förfina resultatet genom adaptiva följdfrågor innan det slutgiltiga callsignet genereras.
+
+## Funktioner
+
+- **Initial Input:** Välj stil (Militär, Humor, Klassisk), ton och ge en kort beskrivning.
+- **Adaptiva Följdfrågor:** Möjlighet att låta AI:n ställa 1-3 relevanta frågor för att bättre förstå vem användaren är.
+- **Smart Generering:** Skapar ett realistiskt callsign med en tillhörande motivering.
+- **Modernt UI:** Byggt med React och Tailwind CSS.
+- **Backend:** FastAPI (Python) som kommunicerar med OpenRouter (Gemini-2.0-Flash).
+
+## Arkitektur
+
+Projektet är uppdelat i två delar:
+- `/frontend`: React-applikation byggd med Vite.
+- `/backend`: FastAPI-server.
+
+Hela stacken är containeriserad med Docker.
+
+## Kom igång
+
+### Förutsättningar
+
+- Docker och Docker Compose installerat.
+- En API-nyckel från [OpenRouter](https://openrouter.ai/).
+
+### Installation
+
+1. Klona repot:
+   ```bash
+   git clone ssh://git@git.sa6anw.se:2222/sa6anw/HandleAgent.git
+   cd HandleAgent
+   ```
+
+2. Skapa en `.env`-fil i rotmappen:
+   ```env
+   OPENROUTER_API_KEY=din_api_nyckel_här
+   ```
+
+3. Starta med Docker Compose:
+   ```bash
+   docker-compose up --build
+   ```
+
+4. Öppna webbläsaren på `http://localhost:5173`.
+
+## Utveckling
+
+Om du vill köra komponenterna separat:
+
+### Backend
+```bash
+cd backend
+pip install -r requirements.txt
+uvicorn main:app --reload
+```
+
+### Frontend
+```bash
+cd frontend
+npm install
+npm run dev
+```

+# React + Vite
+
+This template provides a minimal setup to get React working in Vite with HMR and some ESLint rules.
+
+Currently, two official plugins are available:
+
+- [@vitejs/plugin-react](https://github.com/vitejs/vite-plugin-react/blob/main/packages/plugin-react) uses [Babel](https://babeljs.io/) (or [oxc](https://oxc.rs) when used in [rolldown-vite](https://vite.dev/guide/rolldown)) for Fast Refresh
+- [@vitejs/plugin-react-swc](https://github.com/vitejs/vite-plugin-react/blob/main/packages/plugin-react-swc) uses [SWC](https://swc.rs/) for Fast Refresh
+
+## React Compiler
+
+The React Compiler is not enabled on this template because of its impact on dev & build performances. To add it, see [this documentation](https://react.dev/learn/react-compiler/installation).
+
+## Expanding the ESLint configuration
+
+If you are developing a production application, we recommend using TypeScript with type-aware lint rules enabled. Check out the [TS template](https://github.com/vitejs/vite/tree/main/packages/create-vite/template-react-ts) for information on how to integrate TypeScript and [`typescript-eslint`](https://typescript-eslint.io) in your project.
