Zotero Literature Verification
Complete workflow for verifying academic literature citations using Zotero MCP with 100% word-by-word PDF reading and token budget management.
Quick Start
When invoked with /zotero-literature-verification, guide the user through:
- Token Budget Estimation - Calculate required tokens based on page count
- PDF Extraction - Extract complete PDF text using PyMuPDF
- Sequential Reading - Read every word from first to last page in chunks
- Citation Verification - Verify citations with line numbers and exact quotes
- Reference Generation - Generate ACM-formatted reference list from Zotero
Zero-Tolerance Protocol ⚠️
CRITICAL: When verifying citations or conducting literature review, you MUST:
Reading Requirements (MANDATORY - NO EXCEPTIONS):
- ✅ Extract COMPLETE PDF text to /tmp
- ✅ Read EVERY SINGLE WORD from first page to last page
- ✅ Cover 100% of the document - NO skipping allowed
- ✅ Use sequential chunks to ensure complete coverage
- ✅ Verify completion by reading References section
- ✅ Track exact line numbers for all citations
- ✅ Monitor token usage after each paper
STRICTLY FORBIDDEN:
- ❌ Reading only Abstract, Introduction, and Conclusion
- ❌ Reading "representative sections" - MUST read ALL sections
- ❌ Using grep/search as substitute for complete reading
- ❌ Skipping methodology, results, or discussion sections
- ❌ Assuming content without actual reading
- ❌ Reading "key parts" and claiming completion
- ❌ Stopping after "getting the main idea"
- ❌ Any form of partial reading or summarization without full coverage
Reading Strategy (NON-NEGOTIABLE):
For ANY paper or document:
- Extract full text to temporary file
- Calculate total lines and plan chunk sizes (250-300 lines per chunk)
- Read sequentially: lines 0-300, 300-600, 600-900, etc.
- Continue until reaching the final line (References section)
- Only after reaching final line may you claim "reading complete"
- Record total lines read as proof of completion
Example for 1200-line paper:
- Chunk 1: Lines 0-300 ✓
- Chunk 2: Lines 300-600 ✓
- Chunk 3: Lines 600-900 ✓
- Chunk 4: Lines 900-1200 ✓
- Total: 1200/1200 lines (100%) ← This is the ONLY acceptable standard
Anti-Cheating Measures:
Self-Audit Before Claiming Completion:
- What is the total line count of this document?
- What is the last line number I read?
- Are these two numbers equal? (If NO, continue reading)
- Did I skip any sections between start and end?
- Can I quote from the middle sections (not just intro/conclusion)?
Penalty for Violation: If you discover you have not read 100% of a document:
- Immediately acknowledge the error
- Re-read the ENTIRE document from beginning
- Update progress tracking to reflect honest completion status
- Do NOT claim completion until 100% coverage achieved
Token Budget Estimation
Formula: Pages × 700 + 1000 = Estimated Tokens
| Papers | Pages | Est. Tokens | Safe? |
|---|---|---|---|
| 1-2 | 10-20 | ~20k | ✅ Safe |
| 3-4 | 30-40 | ~50k | ✅ Safe |
| 5-6 | 50-90 | ~90k | ✅ Safe |
| 7+ | 100+ | ~140k+ | ⚠️ Split sessions |
Token Zones:
- Safe: < 100k used (100k+ remaining)
- Caution: 100-150k used (50-100k remaining)
- Danger: > 150k used (< 50k remaining) → Pause and wait for user
Workflow
Step 1: Extract PDF
import fitz
doc = fitz.open('/Users/Zhuanz/Zotero/storage/XXXXXXXX/Paper.pdf')
text = '\n'.join([p.get_text() for p in doc])
with open('/tmp/paper_full.txt', 'w') as f:
f.write(text)
print(f"✅ {doc.page_count} pages, {len(text)} chars")
Step 2: Read Sequentially
Read in chunks of 250-300 lines:
# Chunk 1: Lines 0-250 (Title, Abstract, Introduction)
Read("/tmp/paper_full.txt", offset=0, limit=250)
# Chunk 2: Lines 250-500 (Methods, early Results)
Read("/tmp/paper_full.txt", offset=250, limit=250)
# Chunk 3: Lines 500-750 (Results, Discussion)
Read("/tmp/paper_full.txt", offset=500, limit=250)
# Chunk 4: Lines 750-1000 (Conclusion, References)
Read("/tmp/paper_full.txt", offset=750, limit=250)
Step 3: Verify Citations
After complete reading, locate exact quotes:
# Find exact line number
grep -n "exact quoted phrase" /tmp/paper_full.txt
# Read context (±20 lines)
Read("/tmp/paper_full.txt", offset=436, limit=40)
Step 4: Get Metadata from Zotero
Use Zotero MCP tools:
mcp__zotero__zotero_get_item_metadata- Get complete metadatamcp__zotero__zotero_search_items- Search by author/year/titlemcp__zotero__zotero_get_item_fulltext- Get PDF text
Step 5: Generate Report
## Verification Report
| Paper | Pages | Status | Issues |
|-------|-------|--------|--------|
| Author 2025 | 15 | ✅ | Corrected: false attribution |
| Author 2024 | 19 | ✅ | None - accurate |

Token Management
Monitor after each paper:
if tokens_remaining < 50000:
print("⚠️ WARNING: Less than 50k tokens remaining")
print("Recommend: Save progress and continue in new session")
Real Performance (from 2026-02-05):
- 6 papers, 91 pages, 369,478 characters
- Token used: 113,000 / 200,000 (56.5%)
- Time: ~2 hours
- Result: 100% accurate verification
Emergency Procedures
Token Budget Exhausted (< 30k remaining)
# Save progress
cat > /tmp/verification_progress.txt << EOF
Completed: Paper1, Paper2, Paper3
Current: Paper4 (line 500/1200)
Pending: Paper5, Paper6
Token used: 150,000
