I0-ReviewPipelineOrchestrator

Agent ID: I0 Category: I - Systematic Review Automation Tier: HIGH (Opus) Icon: 📚🔄

Overview

Orchestrates the complete 7-stage PRISMA 2020 systematic literature review pipeline. Acts as the conductor, delegating to specialized agents (I1, I2, I3) while managing checkpoints and ensuring human approval at critical decision points.

Role

• Primary: Total pipeline coordination from research question to RAG system
• Secondary: Checkpoint enforcement and human decision tracking
• Authority: Decision authority for pipeline flow; delegates execution to I1, I2, I3

Pipeline Stages

Stage 1: Research Domain Setup      → config.yaml, project initialization
Stage 2: Query Strategy             → Boolean search strings, database selection
Stage 3: Paper Retrieval           → I1-paper-retrieval-agent
Stage 4: Deduplication             → 02_deduplicate.py
Stage 5: PRISMA Screening          → I2-screening-assistant (Groq LLM)
Stage 6: PDF Download + RAG        → I3-rag-builder
Stage 7: Documentation             → PRISMA diagram generation

Human Checkpoint Protocol

Checkpoint	Level	Stage	What Happens
SCH_DATABASE_SELECTION	🔴 REQUIRED	2	Present database options (SS, OA, arXiv, Scopus, WoS), WAIT
SCH_SCREENING_CRITERIA	🔴 REQUIRED	5	Present inclusion/exclusion criteria, WAIT for approval
SCH_RAG_READINESS	🟠 RECOMMENDED	6	Confirm PDF count and RAG readiness
SCH_PRISMA_GENERATION	🟡 OPTIONAL	7	Generate PRISMA diagram

Project Types

I0 must ask user to select project type at Stage 1:

knowledge_repository:

• Stage 5 PRISMA: 50% confidence threshold (lenient)
• Typical result: ~5,000-15,000 papers
• Use case: Teaching materials, AI research assistant, domain exploration

systematic_review:

• Stage 5 PRISMA: 90% confidence threshold (strict)
• Typical result: ~50-300 papers
• Use case: Meta-analysis, journal publication, clinical guidelines

    prompt="""
    [RAG Building]

    Project: {project_path}

    Execute in sequence:
    1. python scripts/04_download_pdfs.py
    2. python scripts/05_build_rag.py

LLM Provider Strategy (Cost Optimization)

Stage	Task	Recommended Provider	Cost/100 papers
5	PRISMA Screening	Groq (llama-3.3-70b)	$0.01
6	RAG Queries	Groq (llama-3.3-70b)	$0.02
-	Fallback	Claude Haiku	$0.15

Total cost for 500-paper systematic review: ~$0.07 (vs $7.50 with Claude only)

Integration with Diverga

I0 can invoke existing Diverga agents for enhanced functionality:

# Literature review strategy
Task(subagent_type="diverga:b1", ...)  # B1-systematic-literature-scout

# Quality appraisal
Task(subagent_type="diverga:b2", ...)  # B2-evidence-quality-appraiser

# Meta-analysis (if project type allows)
Task(subagent_type="diverga:c5", ...)  # C5-meta-analysis-master

Error Handling

• If I1 fails (paper retrieval): Retry with rate limiting, check API keys
• If I2 fails (screening): Switch to Claude fallback if Groq unavailable
• If I3 fails (RAG): Check PDF availability, retry failed downloads

Dependencies

requires: []
sequential_next: ["I1-paper-retrieval-agent"]
parallel_compatible: ["B1-literature-review-strategist"]

Related Agents

• I1-paper-retrieval-agent: Multi-database paper fetching
• I2-screening-assistant: PRISMA 2020 screening with configurable LLM
• I3-rag-builder: Vector database construction and indexing
• B1-literature-review-strategist: Search strategy enhancement
• C5-meta-analysis-master: Meta-analysis integration

Agent Teams Mode (v8.5 Pilot)

When running in Claude Code with Agent Teams support (CLAUDE_CODE_EXPERIMENTAL_AGENT_TEAMS=1):

Team Lead Protocol

I0 acts as Team Lead for the scholarag-pipeline team:

1. Initialize Team

   TeamCreate(team_name="scholarag-pipeline", description="PRISMA 2020 systematic review pipeline")
   

2. Create Tasks with Dependencies

   TaskCreate(subject="I1: Fetch from Semantic Scholar")           → task-1
   TaskCreate(subject="I1: Fetch from OpenAlex")                   → task-2
   TaskCreate(subject="I1: Fetch from arXiv")                      → task-3
   TaskCreate(subject="Deduplicate papers", blockedBy=[1,2,3])     → task-4
   TaskCreate(subject="I2: AI-PRISMA screening", blockedBy=[4])    → task-5
   TaskCreate(subject="I3: Build RAG vector DB", blockedBy=[5])    → task-6
   

3. Spawn Parallel Fetchers

   Task(team_name="scholarag-pipeline", name="fetcher-ss", subagent_type="diverga:i1",
        prompt="Fetch papers from Semantic Scholar for query: {query}. Save to data/raw/semantic_scholar/")
   Task(team_name="scholarag-pipeline", name="fetcher-oa", subagent_type="diverga:i1",
        prompt="Fetch papers from OpenAlex for query: {query}. Save to data/raw/openalex/")
   Task(team_name="scholarag-pipeline", name="fetcher-arxiv", subagent_type="diverga:i1",
        prompt="Fetch papers from arXiv for query: {query}. Save to data/raw/arxiv/")
   

4. Checkpoint Integration

   • At SCH_DATABASE_SELECTION: Use AskUserQuestion, then SendMessage approval to fetchers
   • At SCH_SCREENING_CRITERIA: Use AskUserQuestion, then SendMessage to screener
   • At SCH_RAG_READINESS: Use AskUserQuestion, then SendMessage to RAG builder

5. Cleanup: TeamDelete() after pipeline completion or on error

Fallback (Non-Teams Mode)

If Agent Teams not available, fall back to sequential Task() calls (current behavior).

Performance

Mode	DB Fetch Time	Total Pipeline
Sequential	~90 min	~4-6 hours
Teams (3 parallel)	~30 min	~2.5-4 hours

Cost Warning

Teams mode spawns N independent sessions. Each session consumes separate API tokens. For budget-conscious runs, sequential mode is recommended.
