+# BioScientist Agent System
+
+An orchestration layer for **agentic bioinformatics workflows** that combines:
+
+- Dynamic MCP tool registration
+- Dual-mode reasoning (`T1`) and execution (`V1`)
+- Layered validation (`E1`) with Agent System integration
+- File-based shared memory for continual improvement
+
+---
+
+## Why This Repository Exists
+
+`BioScientist/agent_system` is designed to run practical computational biology tasks with a structured loop:
+
+1. Propose hypotheses and strategies
+2. Validate them with increasing rigor (L1 -> L4)
+3. Capture execution evidence and insights
+4. Reuse those insights for better next-round planning
+
+This gives you a reproducible bridge between **LLM reasoning**, **MCP tools**, and **real data artifacts**.
+
+---
+
+## Architecture Overview
+
+### Core Components
+
+- `V1 Executor` (`engines/v1_executor.py`)
+  - Pipeline-style task executor
+  - Routes tools through MCP servers
+  - Supports local and Docker backends
+  - Persists run artifacts and reports
+
+- `T1 Consultant` (`engines/t1_consultant.py`)
+  - Reflection and strategy engine
+  - Generates hypotheses (with data-grounded operations)
+  - Ranks hypotheses by historical success proxies
+
+- `E1 Validator` (`engines/e1_validator.py`)
+  - Multi-level validation engine:
+    - `L1`: rule consistency
+    - `L2`: Agent System/MCP readiness
+    - `L3`: lightweight data-backed validation
+    - `L4`: extended data-backed validation
+  - Calls Agent System runtime `A1.go(...)` when available
+
+- `Shared Knowledge Space` (`shared_memory.py`)
+  - File-based memory bridge across modules
+  - Stores experiment reports, hypotheses, validation reports, insights, and summary statistics
+
+- `Orchestrator` (`orchestrator.py`)
+  - Unified entrypoint wiring `V1 + T1 + E1`
+  - Exposes high-level modes like:
+    - `execute`
+    - `consult`
+    - `autopilot`
+    - `hypothesis-generate`
+    - `hypothesis-loop`
+
+### Runtime Flow (Hypothesis Loop)

+
+---
+
+## Environment Setup (Required)
+
+Our software environment is large. We provide a single setup script to bootstrap dependencies.
+
+### 1) Activate the E1 environment first
+
+```bash
+conda activate biomni_e1
+```
+
+### 2) Install the official pip package first
+
+```bash
+pip install biomni --upgrade
+```
+
+### 3) Run the unified setup script
+
+```bash
+# from the repository root
+bash setup.sh
+```
+
+### 4) (Optional, recommended) Install the latest Biomni from source
+
+```bash
+pip install git+https://github.com/snap-stanford/Biomni.git@main
+```
+
+---
+
+## Quick Start: Hypothesis Loop (Single-Cell Normalization)
+
+### 1) Set Environment Variables
+
+Use your current setup pattern:
+
+```bash
+export GEMINI_API_KEY="<YOUR_GEMINI_API_KEY>"
+export T1_MODEL_BACKEND="gemini"
+export GEMINI_MODEL="gemini-2.5-flash-lite"
+export GEMINI_TEMPERATURE="0.2"
+export GEMINI_TIMEOUT_SECONDS="60"
+export BIOMNI_PATH=/225040511/project/Biomni/data
+export BIOMNI_SOURCE="Gemini"
+```
+
+Optional (recommended for explicit control):
+
+```bash
+export BIOCLAW_BIOMNI_ROOT=/225040511/project/BioScientist/agent_system/engines/v1_executor_backup
+```
+
+### 2) Run the End-to-End Loop
+
+```bash
+python -m agent_system.main \
+  --project_root /225040511/project/BioScientist \
+  hypothesis-loop \
+  --task_scope single_cell_normalization \
+  --user_query "Give me new ideas for normalizing single-cell data" \
+  --n 2 \
+  --top_k 1 \
+  --validate_top_m 1 \
+  --validation_level L4 \
+  --register_mcp true
+```
+
+### 3) Where to Find Outputs
+
+- Loop-level result:
+  - `agent_system/results/hypothesis-loop_<timestamp>.json`
+- Validation runtime reports:
+  - `agent_system/results/e1_runtime/*.json`
+- Data-backed L3/L4 artifacts:
+  - `agent_system/results/l3_reports/*.json`
+  - `agent_system/results/l4_reports/*.json`
+- Agent System execution payloads:
+  - `agent_system/results/biomni_exec/*.json`
+
+---
+
+## Other CLI Modes
+
+### Generate hypotheses only
+
+```bash
+python -m agent_system.main \
+  --project_root /225040511/project/BioScientist \
+  hypothesis-generate \
+  --task_scope single_cell_normalization \
+  --user_query "Give me new ideas for normalizing single-cell data" \
+  --n 10 \
+  --top_k 5
+```
+
+### Register MCP servers only
+
+```bash
+python -m agent_system.main \
+  --project_root /225040511/project/BioScientist \
+  register-mcp
+```
+
+### Consult mode (strategy only)
+
+```bash
+python -m agent_system.main \
+  --project_root /225040511/project/BioScientist \
+  consult \
+  --task_scope single_cell_normalization \
+  --user_goal "Design a robust normalization strategy for cross-batch scRNA-seq."
+```
+
+---
+
+## Notes and Troubleshooting
+
+- If Agent System runtime returns API/provider errors (for example region restrictions), E1 may return `inconclusive` even when local data checks succeed.
+- L3/L4 still produce useful tabular evidence (`rows_scanned`, `missing_rate`, numeric summaries, relevance scores).
+- If you want fully offline execution, switch to a local model source (for example Ollama) and update relevant environment variables.
+- Large MCP sets are automatically reduced in E1 probe mode via minimal config generation for faster startup.
+
+---
+
+## Status Semantics
+
+- `success`: validation/execution reached expected criteria
+- `inconclusive`: partial evidence available but one or more critical external/runtime checks failed
+- `failed`: contradiction or hard runtime failure detected

+
+STRICT GUIDELINES:
+1. ONLY extract tasks that are extremely common and standard in computational biomedical research
+2. Each task MUST have clear, well-defined inputs and outputs
+3. Tasks MUST be generalizable across many different papers and research questions
+4. Be VERY selective - only include tasks that appear in hundreds of papers
+5. If a task is specific to this paper, unclear, or not widely used, DO NOT include it
+6. Focus on computational tasks that can be implemented with Python or Linux code
+7. Each task should be something that could be implemented as a function with clear inputs/outputs
+8. Also identify commonly used databases and software packages mentioned in the text
+9. Tasks MUST be CONCRETE and SPECIFIC - include exact methodological details
+10. Avoid vague task names like "Statistical Analysis" - instead use specific protocol names like "Two-way ANOVA with Tukey's Post-hoc Test using SciPy"
+11. DO NOT include wet lab procedures that cannot be implemented computationally
+12. ONLY include tasks that could be automated with code
+
+For the following chunk of text from an academic paper, provide:
+1. A list of ONLY the most common, generalizable COMPUTATIONAL tasks identified (be extremely selective)
+2. For each task, clearly define:
+   - Task name: A SPECIFIC and CONCRETE name with methodological details (e.g., "RNA-seq Differential Expression Analysis with DESeq2" instead of just "Gene Expression Analysis")
+   - Input: What SPECIFIC data or parameters the task requires
+   - Output: What SPECIFIC data or results the task produces
+   - Code implementation: How this task could be implemented with Python or Linux code, including key libraries/packages
+   - Frequency: How common this computational task is in biomedical research
+   - Standard methods: The established computational techniques used to perform this task
+   - Example: A brief description of how THIS specific paper uses this task (with specific details from the paper)
+3. A list of commonly used databases mentioned in the text (if any)
+4. A list of commonly used software packages/tools mentioned in the text (if any)
