## Phase 3: Zotero MCP Integration

### Prerequisites
- User must have Zotero installed and configured
- Zotero MCP server must be running
- User should have uploaded relevant papers to their library

### Initial Reminder to User

```
Before we proceed with literature collection, please ensure:

1. Your Zotero library contains relevant papers for this research topic
2. If you have specific papers you want referenced, please add them to Zotero
3. Papers with full-text PDFs attached will be most useful

If you haven't prepared your Zotero library yet, I can proceed with open-access
sources and web searches, then you can add Zotero papers later.
```

### Zotero MCP Tool Usage

#### Search User's Library

**Basic Keyword Search:**
```
Tool: mcp__zotero__zotero_search_items
Parameters:
  query: "{research topic keywords}"

Example:
  query: "deep learning medical imaging"
```

**Advanced Search:**
```
Tool: mcp__zotero__zotero_advanced_search
Parameters:
  conditions: based on:
    - title contains {keyword}
    - author contains {name}
    - date > {year}
    - tag is {tag}

Example:
  conditions: [
    {"field": "title", "operator": "contains", "value": "transformer"},
    {"field": "date", "operator": ">", "value": "2022"}
  ]
```

**Semantic Search (if indexed):**
```
Tool: mcp__zotero__zotero_semantic_search
Parameters:
  query: "{natural language research question}"

Example:
  query: "What methods are used for detecting cardiac abnormalities in ECG signals?"
```

#### Retrieve Paper Content

**Get Full Text:**
```
Tool: mcp__zotero__zotero_get_item_fulltext
Parameters:
  item_key: "{key from search results}"

Returns: Full text content of the paper (if PDF attached)
```

**Get Metadata:**
```
Tool: mcp__zotero__zotero_get_item_metadata
Parameters:
  item_key: "{key from search results}"

Returns: Title, authors, abstract, journal, year, DOI, etc.
```

**Get User Annotations:**
```
Tool: mcp__zotero__zotero_get_annotations
Parameters:
  item_key: "{key from search results}"

Returns: User's highlights and annotations on the paper
```

**Get User Notes:**
```
Tool: mcp__zotero__zotero_get_notes

  item_key: "{key from search results}"

Returns: Any notes the user has attached to the paper
```

### Zotero Workflow Example

```
Step 1: Search for papers on the topic
> zotero_search_items(query="machine learning cardiac diagnosis")

Step 2: From results, identify most relevant papers (by title, year)

Step 3: Get full text of key papers
> zotero_get_item_fulltext(item_key="ABC123")

Step 4: Check for user insights
> zotero_get_annotations(item_key="ABC123")
> zotero_get_notes(item_key="ABC123")

Step 5: Get metadata for citation
> zotero_get_item_metadata(item_key="ABC123")
```

## Handling Different Scenarios

### Scenario 1: Rich Zotero Library
```
User has extensive Zotero collection relevant to topic.

Strategy:
1. Start with Zotero semantic search
2. Get annotations/notes for user insights
3. Supplement with web search for recent news/trends
4. Use user's existing organization (collections, tags)
```

### Scenario 2: Empty or Sparse Zotero Library
```
User has no relevant papers in Zotero.

Strategy:
1. Inform user of limitation
2. Rely on WebSearch and open-access sources
3. Provide clear citations for open-access papers
4. Suggest key papers user might add to Zotero
```

### Scenario 3: Very New Topic
```
Limited existing literature available.

Strategy:
1. Focus on foundational/adjacent literature
2. Emphasize why topic is emerging
3. Include recent conference papers/preprints
4. Frame proposal as pioneering work
```

### Scenario 4: Interdisciplinary Topic
```
Topic spans multiple fields.

Strategy:
1. Search across domain-specific databases
2. Identify bridging papers
3. Balance literature from each field
4. Address methodological borrowing
```

## Quality Checks for Literature

### Coverage Check
- [ ] Seminal/foundational works included
- [ ] Recent papers (last 5 years) represented
- [ ] Multiple perspectives/approaches covered
- [ ] Key researchers in field cited
- [ ] Geographic/institutional diversity (if relevant)

### Relevance Check
- [ ] Each paper directly supports a claim
- [ ] No tangential citations
- [ ] Gap papers specifically identify the gap
- [ ] Method papers describe the methods used

### Balance Check
- [ ] Not over-reliant on single author/lab
- [ ] Mix of empirical and theoretical works
- [ ] Both supporting and challenging views
- [ ] Appropriate review-to-primary ratio

### Recency Check
- [ ] ~80% from last 5 years
- [ ] Latest advances included
- [ ] No outdated methods cited as current
- [ ] Historical context appropriately old

## Troubleshooting

### "No results found in Zotero"
```
Solutions:
1. Try broader search terms
2. Check if papers have been uploaded with full text
3. Verify MCP connection is working
4. Ask user to add relevant papers
```

### "WebSearch returns low-quality results"
```
Solutions:
1. Add site filters (site:nature.com, site:arxiv.org)
2. Use more specific terminology
3. Include author names if known
4. Add year constraints
```

### "Cannot access full text"
```
Solutions:
1. Check open-access repositories (arXiv, PubMed Central)
2. Use metadata/abstract only
3. Ask user to obtain and add to Zotero
4. Note limitation in proposal
```

### "Too much literature found"
```
Solutions:
1. Prioritize by citation count
2. Filter by publication venue quality
3. Focus on most recent within each category
4. Limit to papers directly supporting claims
