## 2. Core System Prompt

```
You are James Leung (梁潤賢), Literature Search Specialist at the Impact Data Consortium Chain (IDCC). You are the AI version of James Leung, Executive Director and co-founder of IDCC.

Your primary role is to search the SWRD (Social Work Research Database, 62,602 journal articles, 88 journals, 1989–2025) and SSWR (Society for Social Work Research Conference Archive, 23,793 papers, 2005–2026) databases and reason about the academic evidence found.

PERSONA: You are thoughtful, evidence-led, and grounded in Hong Kong's social work sector. You speak plainly and clearly. You flag gaps in the evidence. You always cite sources with year, journal, and methodology.

CORE TASKS:
1. Execute keyword search using OR-logic FTS + SQL hybrid retrieval
2. Classify results as empirical (★) vs theoretical
3. Identify research methods (quantitative / qualitative / mixed / review)
4. Run trend analysis by 5-year period
5. Retrieve SSWR conference papers for cutting-edge unpublished findings
6. Flag research gaps — what is NOT in the evidence base
7. Hand off to Jessica for statistical debate when evidence warrants

CITATION FORMAT: [Year][Method][★ if empirical] Title — Journal

OUTPUT FORMAT:
- Lead with total results found
- Organise by theme or recency
- Highlight empirical vs theoretical split
- Close with gaps identified and handoff note to Jessica or Tat

LANGUAGE: Match the user's language (English / 繁體中文 / 简体中文).
```

## 4. Search Algorithm

James uses a **hybrid FTS + SQL search** with OR-logic combining FTS relevance ranking and broad SQL ILIKE matching.

### Step 1 — Keyword Extraction
```javascript
function extractKeywords(query) {
  const stopWords = new Set(['and','the','for','are','was','with','that',
    'this','from','into','what','have','can','its','how','does','will',
    'about','which','when','where','why','who'])
  const words = query.trim().split(/\s+/)
    .filter(w => w.length > 2 && !stopWords.has(w.toLowerCase()))
  const chunks = new Set()
  chunks.add(query)  // full query
  for (let i = 0; i < words.length - 1; i++)
    chunks.add(`${words[i]} ${words[i+1]}`)  // bigrams
  words.forEach(w => chunks.add(w))  // unigrams
  return Array.from(chunks).slice(0, 8)
}
```

### Step 2 — FTS Search (per keyword, parallel)
```http
POST /rest/v1/rpc/search_papers_keyword
Content-Profile: swrd
{
  "query_text": "<keyword>",
  "match_count": 20
}
```

### Step 3 — SQL OR Search
```sql
SELECT id, title, abstract, publication_year, journal_name,
       research_method, is_empirical, is_scientific, open_access, doi
FROM swrd.papers_with_journals
WHERE (
  (title ILIKE '%social innovation%' OR abstract ILIKE '%social innovation%')
  OR (title ILIKE '%social enterprise%' OR abstract ILIKE '%social enterprise%')
)
AND is_scientific = true
ORDER BY publication_year DESC
LIMIT 30
```

### Step 4 — Score Merge & Deduplication
- FTS hit = +2 + rank score
- SQL hit = +1
- Deduplicate by `id`
- Return top N sorted by score

### Step 5 — Trend Analysis (optional)
```sql
SELECT (publication_year/5)*5 AS period,
       research_method, COUNT(*) AS n
FROM swrd.papers
WHERE (title ILIKE '%<keyword>%' OR abstract ILIKE '%<keyword>%')
  AND publication_year >= 1989
  AND is_scientific = true
GROUP BY 1, 2
ORDER BY 1, 3 DESC
LIMIT 60
```

## 5. Result Formatting

```javascript
function formatPaper(p, includeAbstract = false) {
  const abs = includeAbstract && p.abstract
    ? `\n   Abstract: ${p.abstract.slice(0, 280)}…` : ''
  const method = p.research_method ? ` [${p.research_method}]` : ''
  const empirical = p.is_empirical ? ' ★empirical' : ''
  return `[${p.publication_year}]${method}${empirical} ${p.title} — ${p.journal_name || 'Journal'}${abs}`
}
```

**Example output:**
```
[2023][quantitative]★empirical Social innovation ecosystem development in Hong Kong — British Journal of Social Work
[2021][qualitative] Community-based social enterprises and participatory governance — Social Policy & Administration
[2019][mixed]★empirical SIE Fund impact evaluation: cross-sector partnerships — Journal of Social Policy
```

## 6. Speciality Domains

James is particularly well-indexed for:

| Domain | SWRD Articles (est.) |
|--------|---------------------|
| Mental health & wellbeing | ~12,000 |
| Child welfare & protection | ~9,500 |
| Elderly care & ageing | ~8,200 |
| Social enterprise & innovation | ~5,100 |
| Community work & participation | ~6,800 |
| Social financing & impact investment | ~2,200 |
| Mainland China social work | ~4,400 |
| Social policy & welfare reform | ~7,300 |

---

## 7. Workflow Integration

James operates in three pipeline modes:

**Mode A (Sequential):** James searches → Jessica debates → Tat reports  
**Mode B (Parallel):** James (research) + Jessica (analysis) simultaneously → Tat reports  
**Mode C (Doc/Idea):** Tat reads input → Jessica decides if James needed → optional James search → Tat final report

**Direct mention:** `@james` routes the user directly to James, bypassing Cici's orchestration. James replies with a focused literature search only.

**Depth levels:**
- **Fast:** Top 10 results → 200-word brief by Tat (< 30 seconds)
- **Standard:** Full search + trend analysis → hand off to full team
- **Deep:** Two-round structured academic debate with Jessica

---

## 8. Multilingual Support

James replies in the user's language:
- `en` — English
- `zh-TW` — Traditional Chinese (繁體中文)
- `zh-CN` — Simplified Chinese (简体中文)

CJK queries are translated to English for database search (the SWRD corpus is in English) then results are summarised in the user's language.

---

## 9. Integration — API Endpoint

```http
POST /api/pipeline
Content-Type: application/json

{
  "question": "What does the evidence say about social enterprise in Hong Kong?",
  "lang": "en",
  "depth": "standard"
}
```

Response: SSE stream with events:
```
data: {"agent":"search","type":"working","message":"Searching SWRD for 'social enterprise Hong Kong'..."}
data: {"agent":"search","type":"done","message":"Found 47 articles. Top themes: ...","data":[...]}
```

Direct James mention:
```http
POST /api/pipeline
{ "question": "@james What are the latest RCTs on elderly mental health?", "lang": "en" }
```

## 10. How to Fork

1. Connect your own Supabase database with social work or sector-specific records
2. Create the `search_papers_keyword` FTS function and `run_sql` function in Supabase
3. Replace the system prompt persona with your own specialist
4. Adjust `extractKeywords()` stop words for your domain
5. Keep the FTS + SQL hybrid merge — it significantly outperforms either alone
6. Set your `Content-Profile` to match your Supabase schema name
