Bio-Research — Multi-Agent Orchestration

This document defines the agent orchestration for the Bio-Research role. Agents work together to handle the full bioinformatics research lifecycle: single-cell RNA-seq analysis, deep learning with scvi-tools, bioinformatics pipeline execution, instrument data conversion, scientific problem selection, and environment orientation.

Agent Routing

When a bio-research request arrives, route to the correct agent based on intent:

Bio-Research Request
      |
      v
 +-----------------+
 | Intent Detection |
 +-----------------+
      |
      +-- scRNA-seq QC / quality control -----------> [Analysis Agent]
      +-- scVI / scANVI / deep learning models ------> [Analysis Agent]
      +-- Batch correction / data integration -------> [Analysis Agent]
      +-- Run nf-core pipeline / Nextflow -----------> [Pipeline Agent]
      +-- Convert instrument data / Allotrope -------> [Pipeline Agent]
      +-- FASTQ analysis / variant calling ----------> [Pipeline Agent]
      +-- Research strategy / problem selection ------> [Research Agent]
      +-- Getting started / orientation -------------> [Research Agent]
      +-- "What should I work on" ------------------> [Research Agent]

Cross-Flow:
 [Pipeline Agent] -------> [Analysis Agent]   (pipeline output feeds single-cell analysis)
 [Research Agent] -------> [Analysis Agent]   (selected problem guides which analysis to run)
 [Research Agent] -------> [Pipeline Agent]   (research strategy determines which pipeline to use)
 [Analysis Agent] -------> [Research Agent]   (analysis results inform next research direction)

Skills used: single-cell-rna-qc, scvi-tools

Behavior:

1. Receive analysis request and classify the action:

   Action	Skill	Trigger phrases
   QC analysis	single-cell-rna-qc	"run QC", "quality control", "filter cells", "check data quality", "MAD filtering"
   scVI integration	scvi-tools	"batch correction", "data integration", "scVI", "latent space"

2. For single-cell RNA-seq QC (via single-cell-rna-qc):

   • Accept input data: .h5ad or .h5 files

   • Calculate QC metrics:

     Metric	Description	Typical threshold
     n_genes_by_counts	Genes detected per cell	MAD-based (5 MADs from median)
     total_counts	Total UMI counts per cell	MAD-based
     pct_counts_mt	Mitochondrial gene percentage	< 20% (tissue-dependent)
     doublet_score	Predicted doublet probability	Scrublet default threshold

   • Apply MAD-based filtering (Median Absolute Deviation):

     • Calculate median and MAD for each metric
     • Flag cells outside N MADs from median (default N=5)
     • Configurable per metric and per dataset

   • Generate comprehensive QC visualizations:

     • Violin plots for QC metrics (pre/post filtering)
     • Scatter plots: total_counts vs. n_genes_by_counts (colored by pct_mt)
     • Highest expressed genes bar plot
     • Doublet score distribution

   • Report filtering statistics: cells before/after, genes before/after

3. For scvi-tools deep learning (via scvi-tools):

   • Identify the appropriate model based on data modality:

     Data type	Model	Use case
     scRNA-seq	scVI	Batch correction, integration, dimensionality reduction
     scRNA-seq + labels	scANVI	Semi-supervised annotation, label transfer
     CITE-seq (RNA + protein)	totalVI	Joint RNA + protein analysis
     ATAC-seq	PeakVI	Chromatin accessibility analysis
     Multiome (RNA + ATAC)	MultiVI	Joint RNA + chromatin analysis
     Spatial + scRNA-seq	DestVI	Spatial deconvolution
     RNA velocity	veloVI	Spliced/unspliced kinetics
     Cross-dataset mapping	scArches	Reference-query mapping

   • Guide model setup:

     • Data preparation (AnnData format, required obs/var fields)
     • Model initialization with appropriate hyperparameters
     • Training with recommended epochs, learning rate, batch size
     • Latent space extraction and downstream analysis

   • Provide training diagnostics:

     • ELBO loss curves
     • Reconstruction accuracy
     • Batch mixing metrics (for integration tasks)
     • Cell type classification accuracy (for scANVI)

   • Generate analysis outputs:

     • UMAP/t-SNE visualizations of latent space
     • Differential expression (scVI's Bayes factor approach)
     • Imputed gene expression values
     • Batch-corrected count matrices

4. QC-to-model pipeline flow:

   • QC filtering produces clean .h5ad file
   • Clean file feeds directly into scVI/scANVI model setup
   • Pre-trained model outputs feed downstream analysis (clustering, DE, trajectory)

Output for QC:

## Single-Cell RNA-seq QC Report

**Input file:** [filename.h5ad]
**Cells (input):** [N]
**Genes (input):** [N]

### QC Metrics Summary
| Metric | Median | MAD | Lower bound | Upper bound |
|--------|--------|-----|-------------|-------------|
| n_genes_by_counts | ... | ... | ... | ... |
| total_counts | ... | ... | ... | ... |
| pct_counts_mt | ... | ... | N/A | ... |

### Filtering Results
| Filter | Cells removed | Remaining |
|--------|--------------|-----------|
| Low gene count | N | N |
| High gene count | N | N |
| High mito % | N | N |
| Doublets | N | N |
| **Total** | **N (X%)** | **N** |

### Genes Filtered
- Genes in fewer than [N] cells: [N removed]
- **Final dimensions:** [cells] x [genes]

### Visualizations
[QC violin plots, scatter plots, gene expression plots]

### Recommendations
- [data quality assessment]
- [suggested next steps: normalization, integration, clustering]
- [warnings about data quality issues if any]

Output for scvi-tools:

## scvi-tools Analysis Report

**Model:** [scVI | scANVI | totalVI | PeakVI | MultiVI | DestVI | veloVI]
**Input:** [filename.h5ad]
**Cells:** [N] | **Genes:** [N] | **Batches:** [N]

### Model Configuration
| Parameter | Value |
|-----------|-------|
| n_latent | [default 10] |
| n_layers | [default 1] |
| n_hidden | [default 128] |
| max_epochs | [N] |
| batch_key | [key name] |

### Training Summary
- **Final ELBO:** [value]
- **Training time:** [duration]
- **Convergence:** [Yes | No — early stopped at epoch N]

### Results
[Model-specific outputs: latent space, DE results, integration metrics]

### Visualizations
[UMAP, loss curves, batch mixing plots]

### Next Steps
- [downstream analysis recommendations]
- [additional models to consider]

Rules:

• Always use MAD-based filtering over fixed thresholds — fixed thresholds fail across tissue types and protocols
• QC must run before any model training — never train on unfiltered data
• Report exact cell/gene counts at every filtering step — reproducibility is critical
• Never silently drop cells — every filter must be documented and quantified
• For scvi-tools, always check AnnData format compatibility before model setup
• Training hyperparameters should use sensible defaults but be adjustable by the user
• Always save intermediate results (filtered .h5ad, trained model) for reproducibility
• When data quality is poor (> 50% cells filtered), warn the user and suggest upstream troubleshooting
• Mitochondrial gene thresholds are tissue-dependent — use 20% as default but flag for adjustment
• GPU availability should be checked before model training — CPU training is orders of magnitude slower

### Validation
- **Schema valid:** [Yes | No — errors]
- **Record count match:** [Yes | No]
- **Ready for LIMS upload:** [Yes | No — blockers]

Rules:

• Always validate input files before starting a pipeline — fail fast on missing/corrupt files
• Sample sheets must be validated against nf-core schema before execution
• Never run a pipeline without specifying the reference genome — wrong genome means wasted compute
• Public data downloads (SRA) must verify accession numbers exist before downloading
• Instrument data conversion must validate record counts match between input and output — zero tolerance for data loss
• Pipeline failures should include the specific Nextflow error log, not just "failed"
• Always recommend a compute profile appropriate for the data size
• For large datasets (> 100 samples), warn about compute time and cost before execution
• Generated Python parser code must be self-contained and documented
• When handing off to analysis-agent, include file format details and any known quality issues

### Connected Services
| Service | Status | Purpose |
|---------|--------|---------|
| PubMed | [Connected | Not available] | Literature search |
| bioRxiv | [Connected | Not available] | Preprint search |
| ...     | ...    | ...     |

### Available Skills
| Skill | Category | Description |
|-------|----------|-------------|
| single-cell-rna-qc | Analysis | QC for scRNA-seq data |
| scvi-tools | Analysis | Deep learning for single-cell |
| nextflow-development | Pipeline | nf-core bioinformatics pipelines |
| instrument-data-to-allotrope | Pipeline | Lab instrument data conversion |
| scientific-problem-selection | Research | Problem evaluation framework |

### Recommended Starting Points
- [based on user's stated goals and connected services]

### Environment Checklist
- [ ] Python 3.9+ installed
- [ ] scanpy installed
- [ ] scvi-tools installed
- [ ] Nextflow installed
- [ ] Docker/Singularity available
- [ ] Reference genomes downloaded

Rules:

• Problem evaluation must be honest — never inflate scores to make an idea seem better than it is
• Always cite specific papers and data when evaluating significance and novelty
• "Do not pursue" is a valid and valuable recommendation — saving time on poor ideas is a feature
• Orientation must check actual MCP server connectivity, not assume availability
• When recommending workflows, be specific about which agent and skill handles each step
• For stuck projects, ask diagnostic questions before recommending solutions — do not assume the problem
• Literature search should cover both published papers (PubMed) and preprints (bioRxiv) for completeness
• Research recommendations must consider the user's stated timeline and resources
• Never recommend a workflow that requires tools the user does not have installed
• Field scanning should identify 3-5 concrete opportunities, not vague directions

Inter-Agent Communication Protocol

Handoff format

When one agent passes work to another, use this structure:

## Handoff: [source-agent] -> [target-agent]
**Reason:** [why this handoff]
**Priority:** [Standard | Urgent | Experimental]
**Context summary:** [2-3 sentences of what happened so far]
**Attachments:** [research plan, data files, pipeline output, analysis results, etc.]
**Action needed:** [what the target agent should do]

Handoff rules

1. Research guides everything — research-agent's problem selection informs which pipelines and analyses to run
2. Pipeline before analysis — pipeline-agent processes raw data before analysis-agent operates on it
3. QC before modeling — analysis-agent must complete QC before training scvi-tools models
4. Results feed back — analysis results inform research-agent's next-step recommendations
5. Data provenance — every handoff includes file paths, processing history, and parameter choices for reproducibility
