Agentic AI: Agents & Tools Explained
Aman KumarTable of contents
Artificial Intelligence (AI) has already transformed how we search, work, shop, and connect. But the world is now moving into a new era of Agentic AI—a stage where AI is not just a passive tool waiting for our prompts but an active agent capable of reasoning, planning, and executing tasks on our behalf.
In simple terms:
Traditional AI is like a calculator—you give input, it gives output.
Agentic AI is like a smart assistant that understands context, plans steps, uses tools, and achieves goals almost like a human teammate.
This blog explores what Agentic AI means, what agents are, how they work, the role of tools, and why this is deeply relevant for India’s growing digital landscape.
🌐 What is Agentic AI?
Agentic AI refers to AI systems that can operate as agents, meaning they can:
Perceive the environment (inputs, context, goals).
Reason about what steps to take.
Act by executing tasks—sometimes autonomously, sometimes with human guidance.
Learn and adapt based on results.
Instead of just answering a query, these systems take initiative. Think of them as digital professionals who can:
Research online.
Use APIs or software tools.
Organize workflows.
Interact with other agents or humans.
This makes Agentic AI a foundation for creating digital employees, personal assistants, and self-managing systems.
🤖 What Are Agents?
An agent in AI is like a “mini-employee” or “digital worker” that follows a loop:
Observation → Collects input (text, data, images, voice).
Reasoning → Decides what to do next.
Action → Executes tasks using tools or APIs.
Feedback → Evaluates results and adjusts.
For example:
You tell an AI agent: “Book me a train from Chandigarh to Delhi tomorrow evening, and find me a good veg thali restaurant near the hotel.”
A normal chatbot may just show you links.
An Agentic AI system can:
Check IRCTC for trains.
Book the ticket using your stored details.
Search Zomato or Google Maps for vegetarian restaurants.
Add everything to your Google Calendar.
The difference is initiative. The agent does not stop at giving you information—it executes like a personal secretary.
🔧 The Role of Tools in Agentic AI
Agents by themselves are smart, but they become powerful only when connected to tools. Tools are like the arms and legs of an AI agent.
Examples of tools:
APIs (for payments, booking, weather, stocks, etc.)
Databases (for storing knowledge)
Browsers (for real-time web search)
Calculators, IDEs, or even robotics systems
When an agent has access to tools, it can perform real-world actions, not just generate text.
Imagine ChatGPT connected to:
UPI payment APIs → “Pay Aman ₹500 on PhonePe.”
ONDC (Open Network for Digital Commerce) → “Order 2kg basmati rice from the cheapest seller nearby.”
IRCTC → “Book a train ticket from Delhi to Varanasi.”
This is where India’s digital public infrastructure (DPI) becomes a superpower. UPI, Aadhaar, DigiLocker, and ONDC are perfect playgrounds for Agentic AI, making India one of the most fertile grounds for adoption.
🧩 How Do Agents Actually Work?
Agents usually follow an agent loop:
Input Understanding → Parse the user’s request.
Planning → Break it into subtasks.
Tool Calling → Use APIs or tools for each subtask.
Result Aggregation → Collect outputs.
Final Answer → Present results or take further steps.
Example: “Find me a good laptop under ₹60,000 and order it.”
Step 1: Understand you want a laptop, budget ₹60k.
Step 2: Decide plan: Search e-commerce → Compare → Select → Order.
Step 3: Call Flipkart/Amazon API → Get list → Compare processors, RAM, reviews.
Step 4: Shortlist the best option.
Step 5: Execute purchase on your behalf.
This multi-step reasoning + tool usage is what differentiates an agent from a simple chatbot.
🇮🇳 Agentic AI in the Indian Context
India is in a unique position because of its Digital Public Infrastructure (DPI), which is the envy of the world.
Some Indian examples where Agentic AI could thrive:
UPI + AI Agents → Imagine saying: “Send rent to my landlord on the 5th every month” → The agent automates it via UPI.
Aadhaar + DigiLocker → “Renew my driving license” → The agent pulls Aadhaar details, uploads forms, and submits.
ONDC + AI → “Order monthly groceries under ₹3,000” → The agent compares sellers across ONDC, orders, and tracks delivery.
IRCTC → “Find the fastest train from Delhi to Lucknow next weekend and book it.”
In a country like India with 1.4 billion people, agents can reduce human effort for billions of small repetitive tasks like bill payments, ticket booking, government services, and healthcare scheduling.
This could be revolutionary in rural areas too, where agents act as digital assistants in local languages. A farmer could ask in Hindi:
“Kal subah ke liye Jaipur mandi ka pyaaz ka rate batao.”
And the agent can fetch market prices, recommend selling options, and even arrange transport through ONDC-linked logistics.
📚 Types of Agents
Task Agents → Do one job (e.g., summarize PDFs).
Conversational Agents → Like chatbots but smarter (e.g., ChatGPT with tools).
Multi-Agent Systems → Teams of agents working together. For example, one agent researches, another writes code, another tests it.
Embodied Agents → AI agents in robots that interact with the physical world.
⚙️ Technologies Behind Agentic AI
LLMs (Large Language Models) → GPT, LLaMA, etc., that understand and reason.
Prompting Techniques → Chain-of-thought, ReAct (Reason + Act).
Vector Databases → Store knowledge for long-term memory.
Tool Integration → APIs, SDKs, plugins (e.g., LangChain, AutoGPT).
Orchestration Frameworks → LangChain, LlamaIndex, CrewAI for managing agents.
🚀 Why Agentic AI Matters
Productivity boost → From coding to customer support.
Scalability → A company in India could deploy 1000 AI agents instead of hiring 1000 interns.
Accessibility → Helps non-tech people interact with the digital world.
24x7 Automation → Bill payments, reminders, monitoring systems.
Local Impact → Bridging India’s digital divide by providing services in multiple Indian languages.
🔮 The Future of Agentic AI in India
Agentic AI could be the backbone of India’s next digital revolution, just like UPI was for payments.
Governance → AI agents helping citizens with government schemes.
Healthcare → Agents booking doctor appointments, tracking medicine refills.
Education → AI tutors guiding students in Hindi, Tamil, Punjabi, Bengali.
Startups → Indian founders can build entire companies powered by AI agents instead of large teams.
As we say in India, “Jugaad se leke innovation tak sab possible hai.” Agentic AI is where jugaad meets world-class AI infrastructure.
⚠️ Challenges and Considerations
Ethics → Should agents act fully independently?
Security → What if someone hacks an agent linked to your UPI?
Regulation → India will need laws for safe usage.
Bias → Ensuring fair results across languages and regions.
🌟 Conclusion
Agentic AI represents a major leap from traditional AI. It’s not just about asking and answering—it’s about delegating real work.
With India’s unique digital stack (UPI, Aadhaar, ONDC), we are in a golden position to lead the world in agentic AI adoption. These agents can empower students, professionals, farmers, and entrepreneurs alike.
The future is clear:
Yesterday, AI answered questions.
Today, AI assists.
Tomorrow, AI will act.
And in India, that future is closer than we think.
