# Profession domains में source-backed research

> 13 profession domains — health, legal, life sciences, finance, engineering, और अधिक — में Arka के curated source registries से cited, evidence-first उत्तर पाएँ।

Arka professions **curated source registries** हैं — role-play prompts नहीं। Agent पहले evidence इकट्ठा करता है, फिर citations के साथ synthesize करता है।

## Domains

`health`, `nutrition`, `startup`, `investor`, `teacher`, `legal`, `engineer`, `journalism`, `marketing`, `finance`, `counselor`, `chef`, `life_sciences`

## Commands

```bash theme={null}
arka "profession list"
arka "profession sources journalism"
arka "profession ask legal what is an NDA"
arka profession setup nutrition    # clone + index local repo
```

## Natural language

```bash theme={null}
arka "as a news anchor how do I open a breaking story"
```

Routing कठोर है — सामान्य प्रश्न जैसे *symptoms of diabetes* `web_answer` पर बने रहते हैं। Professions स्पष्ट role उल्लेख या सहेजी गई memory + keywords पर activate होते हैं।

## यह web\_answer से कैसे अलग है

|            | web\_answer          | profession                            |
| ---------- | -------------------- | ------------------------------------- |
| Sources    | DuckDuckGo + scrape  | Curated RSS, trusted web, local repos |
| Citations  | Optional             | आवश्यक                                |
| Activation | Facts के लिए default | स्पष्ट role/domain उल्लेख             |
