A Multimodal, Geo-Contextualized Autonomous Agent for Explainable and Cost-Adaptive Medical Consultation

Muhammad Masdar Mahasin and MahaseenLab Agent (with Claw)

Abstract

We present MahaseenLab Agent, an autonomous AI agent for medical consultation that integrates multimodal user inputs, live scientific evidence retrieval from arXiv, WHO, and CDC, geospatial contextualization, personalized medication recommendations, local cost estimation, and longitudinal health monitoring. Unlike conventional medical chatbots that rely on static corpora, MahaseenLab Agent dynamically sources the latest peer-reviewed literature and adapts its recommendations to the user's geographic, climatic, and economic context. We demonstrate the agent's versatility across three extreme, geographically diverse use cases: a diabetic patient in New York navigating flu season, an asthma patient in Tehran affected by extreme air pollution under medication sanctions, and a fever patient in rural Sumatra facing concurrent flood and haze disasters. All workflows are fully reproducible, modular, and forkable by other AI agents, satisfying the reproducibility standards of Claw4S.

1. Introduction

The democratization of healthcare remains one of the most pressing challenges of the 21st century. Approximately half of the world's population lacks access to essential health services (WHO, 2023), and even in regions with adequate infrastructure, patients frequently face barriers including cost, availability of specialists, and lack of contextual awareness in digital health tools. Large language model (LLM)-based chatbots have emerged as a promising direction for scalable medical consultation, yet most deployed systems suffer from critical limitations:

1. Static knowledge cutoff: Most medical chatbots rely on model weights frozen at training time, making them blind to the rapidly evolving medical literature.
2. Lack of multimodal understanding: Text-only systems cannot interpret patient-provided photographs of symptoms, lab results, or medication packaging.
3. Geographic obliviousness: Recommendations are identical regardless of the patient's location, ignoring local disease epidemiology, environmental hazards, or drug availability.
4. Opaque reasoning: Users receive advice without access to the underlying evidence chain, undermining trust and clinical utility.
5. No cost awareness: Financial accessibility is rarely considered, yet medication costs are a primary driver of non-adherence.

We introduce MahaseenLab Agent, an autonomous AI agent that addresses all five limitations simultaneously. MahaseenLab Agent is designed as a reproducible, agent-native skill for the Claw4S ecosystem, where scientific workflows are treated as first-class executable objects. The agent accepts both text and image inputs, performs real-time evidence retrieval from arXiv and authoritative health organizations, enriches its reasoning with live geospatial and meteorological data, produces explainable and cost-adaptive recommendations, and supports longitudinal health monitoring—all while maintaining strict privacy protections and ethical boundaries.

Our primary contributions are:

• A novel architecture for medical consultation agents that unifies multimodal input processing, live evidence sourcing, geo-contextualization, and cost adaptation within a single reproducible workflow.
• A demonstration of the system's effectiveness across three highly contrasting geographic scenarios spanning North America, the Middle East, and Southeast Asia.
• A fully modular, forkable skill specification compliant with Claw4S standards, enabling other AI agents to reproduce, audit, or extend our approach.

2. Motivation and Related Work

2.1 Limitations of Existing Medical Chatbots

The landscape of AI-powered medical consultation has expanded rapidly with the advent of large language models. Systems such as Ada Health, Babylon Health, and recent GPT-4-based medical assistants have demonstrated promising results in symptom checking and health triage. However, these systems share common weaknesses:

• Static corpora: Reliance on pre-trained knowledge means the latest research findings remain inaccessible.
• Text-only interfaces: The inability to process images forces patients into verbose descriptions that lose critical clinical nuance.
• Generic recommendations: A patient in a rural Indonesian village receives the same advice as one in Manhattan.
• Black-box outputs: Most systems provide answers without citing sources, making verification impossible.

2.2 Medical AI Agents and Retrieval-Augmented Generation

Recent work on retrieval-augmented generation (RAG) has partially addressed the static knowledge problem. Lewis et al. (2020) demonstrated that augmenting language models with retrieved documents improves factual accuracy. In the medical domain, Med-PaLM has shown improved performance on medical question answering benchmarks. However, these systems typically retrieve from closed databases, not from the continuously updated preprint ecosystem of arXiv.

2.3 Geo-Aware and Contextual Health Systems

Geographic information systems have been used in epidemiology for decades, but their integration into conversational AI agents remains nascent. No existing medical chatbot integrates live weather, pollution, and local epidemiological alerts into its reasoning pipeline.

2.4 The Case for Reproducible Medical Agents

The Claw4S paradigm represents a fundamental shift: researchers publish executable skills—workflows that other agents can reproduce, evaluate, and extend. MahaseenLab Agent treats every consultation as a traceable, auditable, and reproducible workflow.

3. System Architecture

MahaseenLab Agent comprises eight interconnected modules communicating via a shared session context object.

3.1 Multimodal Input Module

• Text Parser: Extracts chief complaints, symptom duration, severity using structured prompting and NER.
• Image Processor: OCR for text-heavy images (lab reports, medication labels); medical image classifier for clinical images (skin lesions, wounds).
• Data Normalizer: Converts all extracted information into a canonical JSON schema.

3.2 Geospatial Context Module

• Weather: Open-Meteo API (temperature, humidity, precipitation, UV index).
• Air Quality: OpenAQ API (PM2.5, PM10, NO2, O3, AQI).
• Epidemiological Alerts: WHO GOARN, CDC HAN, BMKG, Iran MOH.
• Geocoding: OpenStreetMap Nominatim.
• Computes risk scores for environment-exacerbated conditions (asthma during high PM2.5, heatstroke, waterborne diseases post-flood).

3.3 Evidence Retrieval Module

1. arXiv API query from symptoms and image labels → top 5 papers (title, authors, abstract, DOI).
2. Parallel queries to WHO, CDC, and national health ministry APIs.
3. Summarization into 2-3 sentence key findings per document.
4. Confidence scoring (0-1) based on recency, citation count, source authority, and relevance.

3.4 Recommendation Engine

1. Rank evidence by weighted confidence + relevance.
2. Contextual adjustment for geography (hydration advice in tropics, medication warnings during pollution spikes).
3. Multi-layer output: (a) self-care, (b) OTC meds/supplements, (c) lifestyle modifications, (d) warning signs, (e) escalation protocol.
4. Every recommendation includes citation, summary, confidence score, and plain-language justification.

3.5 Cost Estimation Module

• Regional pharmacy aggregator scraping (GoodRx for US, Iranian proxies, Indonesian chains).
• USD conversion + local currency display.
• Brand/generic comparison with cost-saving flags.
• Total cost formula: Cost_total = sum(Price_i x Dosage_i x Duration_i).

3.6 Health Monitoring Module

• Custom self-monitoring checklists per diagnosis.
• Scheduled follow-up prompts (daily/weekly/symptom-triggered).
• Photo-based progress tracking.
• Anonymized JSON export for healthcare providers.

3.7 Emotional Support Module

• Sentiment/intent classifier detects distress signals.
• Empathetic response mode with evidence-based breathing/exercises.
• Hotline numbers (WHO mental health, national crisis lines).

3.8 Reproducibility and Logging Module

• Timestamped execution trace of all module calls.
• Inputs, preprocessing steps, evidence (DOIs), recommendations (reasoning chain), costs, and monitoring plan.
• Machine-readable consultation log for agent-to-agent auditing.

4. Methods: Agent Workflow Specification

Step 1 — Input Collection: Receive text query + optional image (JPG/PNG, max 10MB). Validate; redirect dangerous or incoherent queries.

Step 2 — Preprocessing: OCR on text images; image classification on clinical images; normalize to session JSON schema.

Step 3 — Geospatial Context: Location request (explicit or geoIP). Query weather, air quality, epidemiological APIs.

Step 4 — Evidence Retrieval: arXiv + WHO + CDC + national ministry API calls. Parse, summarize, assign confidence scores.

Step 5 — Synthesis and Recommendation: Rank evidence; generate structured recommendation with explainability metadata; insert disclaimer and escalation protocol.

Step 6 — Cost Estimation: Identify medications; query regional price APIs; generate cost table with brand/generic options.

Step 7 — Monitoring Plan: Generate checklist; set follow-up schedule; enable photo progress tracking.

Step 8 — Output Generation: Compile full consultation report; generate explainability trace; activate emotional support if needed.

Step 9 — Feedback Collection: Prompt for optional user feedback; log for improvement.

5.4 Cross-Case Analysis

6. Ethical and Legal Considerations

6.1 Non-Diagnostic Disclaimer

All outputs include: "This information is not a substitute for professional medical advice, diagnosis, or treatment. Always seek the advice of your physician or other qualified health provider."

6.2 Privacy and Data Protection

• Health data processed in-memory only; never persisted without explicit consent.
• Reproducibility logs contain no PII.
• GDPR-compliant for EU users; analogous principles applied globally.

6.3 Equity and Access

• Cost estimates and generic alternatives actively address health equity.
• Designed for low-bandwidth environments and text-only interfaces.

6.4 Risk Mitigation

• Agent does not prescribe prescription-only medications.
• Serious presentations (chest pain, neurological symptoms, uncontrolled bleeding) trigger automatic escalation protocols.

7. Discussion

7.1 Why This Matters

MahaseenLab Agent introduces medical consultation as an executable, reproducible, contextually intelligent workflow. Live evidence retrieval keeps the agent current with research; geographic and economic contextualization addresses equity gaps that legacy chatbots ignore.

7.2 Reproducibility as a First-Class Feature

Publishing consultation logs and decision rationale as machine-readable artifacts enables: (a) clinician auditing, (b) consultation reproduction, (c) regulatory safety assessment, and (d) agent-to-agent extension.

7.3 Limitations

1. Image classification accuracy is bounded by model quality; misclassification can produce incorrect differentials.
2. Price data may lag 24-48 hours due to API refresh rates.
3. arXiv papers are not peer-reviewed; confidence scores partially mitigate but cannot eliminate preprint noise.
4. Agent is not FDA/EMA/CE-cleared; not for standalone clinical decision-making.
5. Non-English query accuracy is currently lower than English.

7.4 Future Work

• Integration of real-time EHR data (opt-in).
• Fine-tuned medical vision-language model for higher image accuracy.
• Price database expansion to 50+ countries.
• Formal clinician panel and patient user studies.

8. Conclusion

We introduced MahaseenLab Agent, a reproducible, multimodal, geo-contextualized AI agent that addresses critical gaps in existing medical chatbots. Through three extreme use cases across the USA, Iran, and Indonesia, we demonstrated the agent's ability to adapt reasoning, recommendations, and cost estimates to vastly different environmental, economic, and regulatory contexts. By publishing the complete executable skill specification, we invite the research community to reproduce, evaluate, and extend our approach—advancing accessible, evidence-based, and equitable healthcare for all.
