What Are AI Agents?

AI agents are autonomous software systems that use artificial intelligence to make decisions and perform tasks on behalf of users, often interacting with their environment and adapting over time

With a clear understanding of what AI agents are, let’s now hear from the developer community. Practical insights and real-world examples from AI practitioners bring these ideas to life….

AI agents find applications across many enterprise domains, including software design, IT automation, code generation, and conversational assistance. They rely on the natural language understanding capabilities of large language models (LLMs) to process user inputs step-by-step, triggering external tools or actions when needed for deeper context.

Having seen how AI agents are driving real impact in diverse industries, it's time to explore the technology powering these intelligent systems. Let's dive into how AI agents work under the hood and uncover the key traits that set them apart from traditional automation.

How AI Agents Work

At the core of AI agents are large language models, frequently referred to as LLM agents. Traditional LLMs, like IBM’s Granite models, OpenAI’s GPT-3: Widely known for its text generation and conversational capabilities, powering a broad range of chatbots and content creation tools,Google LaMDA: Focused on conversational AI, enabling natural dialogue flows without autonomous task execution generate responses based on their training data but are limited by inherent knowledge and reasoning constraints. Agentic technologies improve upon these models by integrating backend tool-calling mechanisms that allow agents to access up-to-date information, autonomously create subtasks, and optimize workflows towards complex objectives.

These autonomous agents learn to adapt to users’ needs over time by storing past interactions in memory and planning future steps, providing a personalized and comprehensive experience. Tool calling without human intervention expands the range of real-world applications for AI agents.

Key Characteristics of AI Agents

Traditional automation systems are rule-based, static, and reactive. They follow fixed sequences and cannot adapt or learn from new data, requiring manual updates and intervention. Such systems excel at repetitive, narrowly defined tasks but falter when facing complexity or unexpected changes.

AI agents overcome these challenges through their key characteristics:

• Autonomy: Making independent decisions and acting in real time without constant supervision.

• Adaptability: Learning continuously from new data and evolving environments.

• Goal-Oriented Behavior: Strategically focusing actions to meet objectives.

• Perception: Understanding context via diverse inputs for situational awareness.

• Proactivity: Anticipating needs and initiating actions ahead of time.

• Continuous Learning: Improving decision-making based on experience.

• Collaboration: Seamlessly coordinating with other agents and humans.

Together, these traits enable AI agents to dynamically plan, learn autonomously, and collaborate effectively transforming how businesses operate across industries. Let’s see how enterprises are putting these capabilities to work.

Enterprise Applications of AI Agents

AI agents are reshaping how enterprises operate by automating complex workflows, enhancing decision-making, and driving innovation across industries.

• Software Design and Development - In software development, AI agents like Windsurf and Cursor are revolutionizing coding by generating accurate snippets, catching bugs early, automating tests, and streamlining version control. Their deep understanding of project context not only speeds up development cycles but also raises software quality, empowering developers to build robust applications faster and with greater confidence.

• Sales, Marketing, and Customer Support - Sales and marketing teams benefit from AI agents automating lead qualification, personalized outreach, and campaign management. Tools such as Lindy and Apollo identify promising leads, personalize communication, and integrate effortlessly with CRM platforms to accelerate pipeline growth and boost ROI. Meanwhile, AI-powered virtual assistants and chatbots in customer support deliver 24/7 service, quickly resolving inquiries, escalating complex issues appropriately, and continuously learning to improve customer experiences.

• Accounting and Finance - Financial departments leverage AI agents to transform operations—streamlining invoice processing, automating expense reporting, detecting fraud, and conducting real-time risk assessments. Trullion’s agentic AI, for example, automates lease accounting and audit preparation, helping finance teams reduce errors and focus on strategic decision-making with confidence.

• Human Resources - AI agents enhance HR functions by automating candidate screening, organizing onboarding, scheduling training, and analyzing employee sentiment. Products like Humanly and Oleeo help HR teams engage candidates more effectively and proactively identify burnout risks, contributing to a healthier and more productive workforce.

From code generation to 24/7 support, AI agents are everywhere. Ready to see what’s under the hood? Let’s break down the main agent types and how each delivers unique capabilities

For a detailed overview of the main types of AI agents, their functionalities, and real-world applications, see this comprehensive guide by IBM

Types and Use Cases of AI Agents

Understanding the different types of AI agents is crucial before building them, as their design determines how they operate and solve problems. AI agents vary by complexity and the decision-making logic they employ:

AI agents vary from simple rule-based reflex systems to advanced learners. 

The core types include:

• Simple Reflex Agents: These react to immediate input with predefined rules, suitable for straightforward tasks like basic automation and error correction.

• Model-Based Reflex Agents: They maintain an internal model of the environment, improving decisions by considering hidden states, as seen in smart home systems.

• Goal-Based Agents: Designed to plan and act toward specific objectives, these agents navigate complex scenarios like inventory management.

• Utility-Based Agents: They evaluate actions by a “goodness” measure or utility, often used in financial portfolios balancing risk and reward.

• Learning Agents: These adapt behavior through experience, continuously improving tasks like spam filtering or recommendations.

Architecturally, agents can be hierarchical, with layered decision-making, or multi-agent systems that cooperate to handle sophisticated workflows.

Agent environments influence behavior:

• Fully Observable Agents have complete knowledge of their surroundings, like in healthcare monitoring.

• Partially Observable Agents must infer missing data, common in recommendation engines without full user context.

Real-World AI Agent Examples

• Action Agents: Automate tasks like investment data analysis (e.g., an AI agent pulling stock data from Bloomberg and doing risk assessments).

• Email Agents: Automate personalized outreach like Mailchimp’s AI-powered campaigns.

• Robo-Advisors: Financial platforms like Betterment or Wealthfront offering autonomous wealth management.

• Healthcare Agents: IBM Watson for Oncology analyzing patient data and suggesting treatments.

• E-commerce Agents: Amazon’s AI managing inventory, pricing, and recommendations.

• Lead Management Agents: AI tools like Salesforce Einstein automating lead scoring and follow-ups.

These examples show how AI agents boost efficiency and decision-making across industries. Let’s look at a workflow example—a Sales Pipeline AI Agent automating key sales tasks to help teams work smarter and faster.

Specific Workflow Example: Sales Pipeline Agent

Imagine a sales representative saying in natural language:

"Show me all deals closing this month that don’t have an active demo scheduled. Send reminders to the account owners, and create a forecast update for leadership."

‍

The AI agent instantly:

• Fetches live pipeline data from the CRM,
• Filters deals by closing date and demo status,
• Sends personalized reminders to account owners,
• Generates a clear forecast report highlighting risks,
• Integrates with other enterprise tools for seamless execution.

This automation streamlines multiple manual steps into one smooth process, boosting productivity and decision-making accuracy. The agent continues learning from outcomes to improve over time.

By understanding the spectrum of AI agent types, their unique strengths, and how they’re applied in real workflows, you’ll be able to pinpoint which agent approach matches your business goals. This clarity helps you design, select, and implement the right AI agent architecture turning complex automation needs into strategic, scalable solutions tailored for your environment.

Before diving into the build steps, let’s first confirm whether you need a full AI agent or a simpler workflow.

Agents vs. Workflows: Understanding the Difference

Multiple Perspectives on "Agent"

The term agent is used in diverse ways in AI. Some define agents as fully autonomous, long-running systems capable of complex independent operations, while others view them more narrowly as prescriptive workflows executed step-by-step. This ambiguity often causes confusion about what truly constitutes an AI agent.

Anthropic’s Distinction

Anthropic, a leader in agentic AI research, draws a clear line between two key concepts: workflows and agents.

• Workflows are systems where large language models (LLMs) and tools are orchestrated through predefined, fixed code paths. This structure makes workflows predictable and orderly, ideal for tasks that are consistent and repeatable.
• Agents are systems in which LLMs dynamically control their own processes and tool usage. Agents adapt their behavior based on ongoing feedback, make decisions on the fly, and flexibly manage workflows in real time.

How to Assess Your System Requirements Before Building an AI Agent

Choosing Between Agents and Workflows 

When deciding to develop an AI agent, it’s crucial to first understand the complexity and flexibility your system requires. Here are key factors to consider in evaluating your system’s needs:

‍

This table clearly contrasts when workflows or AI agents are appropriate based on key system

Understanding the distinctions and proper use cases of agents versus workflows enables developers to create AI solutions that are both effective and efficient by choosing the approach workflows for simplicity or agents for autonomy that best fits their application's needs without unnecessary complexity.

With a clear choice between workflows and agents, it’s time to get hands-on. Next, we’ll walk through a step-by-step process to build an AI agent from defining its purpose to deploying and monitoring it in production..

How to Build an AI Agent

Building AI agents begins with understanding three fundamental components:

1. Model

The core AI model (usually a large language model like GPT) powers the agent's reasoning and language understanding. Different tasks may require different models based on complexity, cost, and latency.

2. Tools

Tools extend the agent’s abilities to interact with the external world. They fall into three categories:

• Data Tools: Retrieve information from databases, documents, or the web.

• Action Tools: Perform tasks like sending emails, updating records, or triggering workflows.

• Orchestration Tools: Allow agents to manage or collaborate with other agents.

3. Instructions

Clear instructions define the agent’s behavior, reduce ambiguity, and guide it through workflows. Well-crafted prompts and rules help agents handle exceptions and complex tasks smoothly.

Example Using OpenAI Agents SDK

weather_agent = Agent(
    name="Weather agent",
    instructions="You are a helpful agent who can talk to users about the weather.",
    tools=[get_weather],
)

‍

Choosing Models and Tools

• Prototype with the most capable model and optimize by testing smaller models.
• Use reusable, standardized tool definitions for maintainability and flexibility.
• Define instructions precisely, breaking down tasks and anticipating edge cases.

The three pillars  every phase of agent creation choosing the right AI model for reasoning, selecting and wiring in tools for data access and actions, and crafting precise instructions to orchestrate behavior so you build agents that are capable, maintainable, and aligned with your goals.
Now that we’ve covered the foundational components, let’s apply these concepts in a real-world use case. Follow along as we build a Marketing Performance Agent from start to finish, illustrating each crucial step for success.

Building a Marketing Performance Agent: A Step-by-Step Developer’s Walkthrough

Imagine building an AI-powered assistant that dives deep into your marketing data analyzing email campaigns and LinkedIn ads side-by-side and instantly tells you which channel drove more signups. This walkthrough shows developers a practical, end-to-end approach to creating such an agent, breaking down every essential step from initial concept to deployment and scaling. Using this marketing example, learn how to build scalable, reliable AI agents that transform raw data into actionable business insights

Step 1: Define the Agent’s Purpose & Scope

Start by outlining exactly what your agent needs to do:

Goal: Compare Last Month’s Email and LinkedIn Campaign Performance

The main job of this agent is to look at how well your email campaigns and LinkedIn ads did in the past month. It will check important numbers like how many people signed up, clicked, or took action on each channel. The agent helps you quickly see which marketing method worked better, so you can make smart decisions.

Constraints: What the Agent Needs to Handle

• Large Amounts of Data:  Marketing data can be huge, with many records. The agent should be able to handle lots of data without slowing down or crashing.

• Protecting Privacy:  The agent must keep personal information safe by hiding details that could identify someone and using secure ways to connect to your data sources. This ensures you follow privacy laws and keep customer data safe.

• Easy to Use:  The agent should fit nicely into the tools you already use (like dashboards or apps). This way, your marketing team can easily get the answers they need without extra hassle.

Agent Type: A Smart Assistant Focused on Analysis

This agent is designed to solve a specific task—it thinks carefully and follows steps to analyze data and generate clear answers. It’s not just made for chatting or small talk; instead, it focuses on giving precise reports and useful insights about your marketing campaigns. This means it’s helpful for serious business decisions where accuracy matters.

class MarketingPerformanceAgent:
    def __init__(self):
        # Define the main goal of the agent
        self.goal = (
            "Compare campaign signup performance from email and LinkedIn ads "
            "for the previous month."
        )
        # State operational constraints the agent must respect
        self.constraints = {
            "handle_large_datasets": True,  # Ability to process large volumes of data efficiently
            "data_privacy": [               # Privacy considerations
                "anonymize personally identifiable info",
                "secure API authentication"
            ],
            "integration": "Seamless embedding in marketing dashboards or apps"
        }
        # Describe the agent's nature and expected behavior
        self.agent_type = (
            "Goal-driven reasoning engine focused on data analysis "
            "and generating performance summaries, not a conversational chatbot."
        )
# Example usage:
agent = MarketingPerformanceAgent()
print(agent.goal)
print(agent.constraints)
print(agent.agent_type)

• This block initializes the agent and sets clear definitions of its purpose (self.goal) and important operational constraints (self.constraints).

• The agent is described as a specialized reasoning engine designed for analyzing marketing data, not for casual conversation (self.agent_type).
  

Step 2: Gather, Clean, and Prepare Essential Data

Quality data is key to building an effective AI agent. Start by connecting to your data sources and preparing the data for analysis:

• Connect to data sources: Retrieve email campaign logs capturing metrics like opens, clicks, and conversions. Similarly, connect to the LinkedIn Ads API to fetch impressions, click-through rates (CTR), and spend data.
• Clean and normalize data: Remove duplicates, fix missing or inconsistent values, and standardize data formats so metrics from different platforms can be compared fairly.
• Define key entities: Identify and label important fields such as campaign_id and channel to maintain clear context across datasets.
• Additional best practices:
  
  • Annotate or label data if training AI models requiring intent or entity recognition.
  • Use data augmentation or synthetic data generation to enrich and diversify training data.
  • Automate your ETL (Extract, Transform, Load) pipeline to keep data current without manual effort.
  • Anonymize sensitive information to maintain user privacy and comply with regulations.

Starting with clean, well-prepared data ensures your marketing agent makes accurate and reliable comparisons when analyzing campaign performance

class MarketingPerformanceAgent:
    def fetch_email_data(self):
        # Simulated fetch from email platform logs
        raw_email_data = [
            {"campaign_id": "email001", "opens": 1000, "clicks": 150, "conversions": 50},
            {"campaign_id": "email002", "opens": 850, "clicks": None, "conversions": 40},  # Missing clicks
            {"campaign_id": "email001", "opens": 1000, "clicks": 150, "conversions": 50}  # Duplicate entry
        ]
        return raw_email_data

    def fetch_linkedin_data(self):
        # Simulated fetch from LinkedIn Ads API
        raw_linkedin_data = [
            {"campaign_id": "linkedin001", "impressions": 20000, "ctr": 0.05, "spend": 3000},
            {"campaign_id": "linkedin002", "impressions": 15000, "ctr": 0.04, "spend": 2500}
        ]
        return raw_linkedin_data

    def clean_and_normalize(self, raw_data, platform):
      




    # Remove duplicates
     unique_data = {frozenset(item.items()): item for item in raw_data}.values()
        cleaned = []
        for item in unique_data:
            if platform == "email":
                # Fill missing clicks with 0
                item["clicks"] = item.get("clicks") or 0
                # Normalize conversions to float
                item["conversions"] = float(item.get("conversions",0))
                # Define channel field
                item["channel"] = "email"
            elif platform == "linkedin":
                # Normalize CTR to percentage
                item["ctr"] = float(item.get("ctr", 0)) * 100
                item["channel"] = "linkedin"
            cleaned.append(item)
        return list(cleaned)

    def prepare_data(self):
        raw_email = self.fetch_email_data()
        raw_linkedin = self.fetch_linkedin_data()

        email_data = self.clean_and_normalize(raw_email, "email")
        linkedin_data = self.clean_and_normalize(raw_linkedin, "linkedin")

        return email_data, linkedin_data

# Example usage
agent = MarketingPerformanceAgent()
email_cleaned, linkedin_cleaned = agent.prepare_data()
print("Cleaned Email Data:", email_cleaned)
print("Cleaned LinkedIn Data:", linkedin_cleaned)

‍

Explanation:

• fetch_email_data and fetch_linkedin_data simulate pulling raw data from APIs or logs.
• clean_and_normalize removes duplicates, fills missing values, standardizes metrics, and adds a channel field for clarity.
• prepare_data orchestrates fetching and cleaning to produce ready-to-use datasets for the agent’s analysis.

This practical example helps developers understand the importance of starting with clean, consistent data and gives them a solid foundation to build their marketing AI agents

Step 3: Choose the Right Decide the Framework / Agent Builder

The orchestration layer is the central control system that coordinates how different AI agents, tools, and data sources work together to complete tasks smoothly and reliably. It manages workflows, handles dependencies, monitors execution, and ensures each part of your AI system communicates effectively.

Real-World Example: Customer Support Automation

Imagine a company automating customer service using AI:

• When a ticket arrives, the orchestration layer routes it to an AI agent that checks the knowledge base and drafts a response.
• If confident, the AI responds immediately; if not, the orchestration escalates to a human expert.
• It logs interactions and updates dashboards in real time.

This orchestration reduces response times by 40%, frees humans for complex cases, and ensures seamless, efficient service.

From this example, you can see how crucial orchestration is. To build such coordinated AI agents, you need the right frameworks and tooling that handle these complex workflows reliably.

Popular Orchestration Frameworks

When building AI agents, the orchestration layer determines how reliably your agents can coordinate tools, memory, and workflows. The right framework keeps everything synchronized — from reasoning and tool execution to observability and debugging.

Below are some of the most widely used frameworks teams rely on today:

1. LangChain
   The most widely adopted agent framework. It provides modular components like Chains, Memory, and Agents to connect LLMs with APIs, tools, and vector stores. Great for both prototypes and production apps, but setup can feel heavy and orchestration logic still requires manual wiring.
2. LangGraph
   Built by the LangChain team, LangGraph lets you construct stateful, multi-agent systems using a graph-based model. You get transparent execution, human-in-loop checkpoints, and persistent memory — ideal for debugging complex workflows, though it comes with higher setup complexity.
3. CrewAI
   A framework built around role-based multi-agent collaboration (think researcher, writer, reviewer). Excellent for structured, cooperative workflows, but still maturing in ecosystem depth and lacks robust observability.
4. AutoGPT
   The early pioneer of autonomous agents. You give it a high-level goal and it decomposes tasks and executes them independently. Great for experimentation, but prone to unreliability and loops — not production ready without tight supervision.
5. OpenAI Agents SDK
   The official toolkit for orchestrating multi-agent workflows within OpenAI’s stack. It offers built-in observability, tracing, and native function-calling — ideal for teams committed to OpenAI’s ecosystem, though less flexible for multi-provider setups.
6. Smolagents (Hugging Face)
   A lightweight, Python-native framework focused on simplicity. Perfect for quick research prototypes and teaching, but limited in orchestration depth, scaling, and monitoring.‍
7. Microsoft Semantic Kernel
   Combines LLMs with plugins, memory, and planners to embed AI inside enterprise systems like Outlook, Teams, or SharePoint. Enterprise-ready and extensible, though heavier for small experiments and with a steeper learning curve.
8. ‍Adopt AI
   Unlike traditional frameworks, Adopt isn’t just another orchestrator — it’s the tooling layer beneath them. It automatically discovers your app’s APIs, entities, and workflows, converting them into agent-ready tools with built-in semantic context, zero manual wiring, and enterprise-grade observability. These tools can plug directly into any of the frameworks above, drastically reducing engineering lift and time to production.

For a deeper comparison of these frameworks — including pros, cons, and where Adopt fits in the agent ecosystem — read our detailed blog on Agent Builder Platforms and Frameworks.

Step 4: Decide the Model

Choosing the right AI model is crucial as it acts as the reasoning “brain” of your agent, determining how well it understands, processes, and responds to complex tasks.

• Smaller LLMs (e.g., GPT-4o-mini, Mistral 7B): These models provide faster response times and lower operating costs. However, they typically have limited capacity for multi-step reasoning and complex workflows, making them suitable for lightweight or less critical applications.

• Frontline Models (e.g., GPT-4o, Claude 3.5, Gemini 1.5): Offering a good balance of performance and cost, these models excel at handling production-grade tasks with strong reasoning, adaptability, and language understanding capabilities.

• Enterprise Models (fine-tuned or privately hosted): When dealing with sensitive data or compliance requirements, fine-tuned or privately hosted models provide customized behavior and enhanced security protocols necessary for enterprise environments.

Selecting the appropriate model depends on the complexity of your agent’s tasks, cost considerations, and privacy or compliance needs.

Step 5: Wire Up the Tools (Tooling Layer)

Setting up API integrations is foundational but often the most tedious part of building AI agents. This step involves:

• Connecting to APIs: Establish connections to data sources (e.g., email platforms, LinkedIn Ads) via REST APIs or SDKs.
• Handling Authentication: Implement auth flows such as OAuth2 or API keys securely.
• Mapping Endpoints: Convert API endpoint responses into well-structured, model-friendly schemas (JSON) with clear field names and sample requests.
• Data Normalization Prep: Prepare data formats to be consistent across sources, e.g., date formats, metrics keys.

Challenges:

• Each new platform requires repeated manual integration work.
• Authentication tokens must be managed carefully to avoid failures.
• Data shape inconsistencies lead to errors in downstream processing.

import requests
class MarketingAPIClient:
    def __init__(self, email_api_key, linkedin_token):
        self.email_api_key = email_api_key
        self.linkedin_token = linkedin_token
        self.email_base_url = "https://api.emailplatform.com/v1"
        self.linkedin_base_url = "https://api.linkedin.com/v2"

    def fetch_email_campaigns(self):
        headers = {"Authorization": f"Bearer {self.email_api_key}"}
        response = requests.get(f"{self.email_base_url}/campaigns/last_month", headers=headers)
        response.raise_for_status()
        return response.json()

    def fetch_linkedin_ads(self):
        headers = {"Authorization": f"Bearer {self.linkedin_token}"}
        response =     requests.get(f"{self.linkedin_base_url}/ads?dateRange=lastMonth", headers=headers)
        response.raise_for_status()
        return response.json()

Step 6: Design the Action Logic

AI agent actions are rarely one-step affairs. You must break goals into atomic steps that can be coded and tested independently. For comparing campaign performance:

• Fetch email and LinkedIn campaigns for a defined period.
• Normalize metrics across different formats (e.g., convert CTR to percentage).
• Sort and filter campaigns based on KPIs (opens, clicks, conversions).
• Compile a unified performance summary comparing channels side-by-side.

Code Sample for Normalization and Comparison

def normalize_email_data(email_data):
    for campaign in email_data:
        campaign['ctr'] = (campaign['clicks'] / campaign['opens']) * 100 if campaign['opens'] else 0
    return email_data

def normalize_linkedin_data(linkedin_data):
    for campaign in linkedin_data:
        campaign['ctr'] = campaign.get('ctr', 0) * 100  # Convert to percentage
    return linkedin_data

def compare_campaigns(email_data, linkedin_data):
    # Simple merge on campaign_id (assuming some overlaps)
    combined = []
    for e_camp in email_data:
        match = next((l for l in linkedin_data if l['campaign_id'] == e_camp['campaign_id']), None)
        combined.append({
            'campaign_id': e_camp['campaign_id'],
            'email_ctr': e_camp.get('ctr', 0),
            'linkedin_ctr': match.get('ctr', 0) if match else None
        })
    return combined

Step 7: Build, Train & Prompt the Agent

Once data is integrated and logic defined, encode the agent’s workflows in JSON, YAML, or code that the orchestration layer reads. Prompt engineering guides the agent’s decision-making:

Example prompt designed for the agent:

“If a campaign's conversion rate is below 2%, flag it as underperforming and recommend further analysis.”

Key workflows include:

• Validating input data range and completeness
• Flagging underperforming campaigns
• Escalating to human intervention triggers

Agent testing involves simulating scenarios and interpreting outputs, iteratively refining prompts and logic to reduce errors.

Step 8: Test & Debug

Once built, rigorous testing and debugging become essential. At this stage, you validate that each API call works correctly, the data is properly normalized, and the workflows execute flawlessly without errors. Effective logging and observability tools are necessary here to identify and resolve issues quickly, avoiding the costly guesswork that plagues many AI projects.

Testing should cover:

• API calls correctness and latency
• Data validity and correctness of normalized values
• Workflow step validation with logging on each transition
• Handling of failed API calls or invalid data inputs

Tools & Techniques

• Use structured logs for tracing workflow execution step-by-step.
• Incorporate retry and backoff strategies for robustness.
• Use unit and integration tests for workflows.

Debugging without observability leads to guesswork and stalled development—highlighting the importance of monitoring tools.

Step 9: Deploy & Monitor

Deploy the agent inside your application embedding it in the UI, chatbots, or backend pipelines.

Finally, after successful testing, you deploy and monitor the agent within your production environment. Embedding agents into user interfaces or backend pipelines, while continuously monitoring performance metrics like adoption, success rates, and error occurrences, ensures sustained reliability and user satisfaction.

Monitoring includes:

• Tracking adoption and user engagement
• Monitoring success rates, error rates, and latency
• Real-time dashboards for uptime and throughput

The Challenge & Solution

• Building and scaling AI agent actions is labor-intensive and complex, especially when handling many marketing workflows.
  

• Manual wiring, frequent debugging, and model–framework juggling cause many projects to stall.
  

• Adopt.ai’s advantage: Auto-discovery of APIs and workflows enables creation of 100+ agent-ready actions in 24 hours, slashing manual effort and accelerating time-to-market.
  

Following these structured steps equips you with the knowledge and practical skills needed to build capable, scalable AI agents—ready to tackle complex tasks and deliver real business value. Now, it’s time to apply this foundation and start building your own AI agents.

Explore official SDKs, frameworks, and community resources to accelerate your development journey:

• OpenAI API SDK
• LangChain Documentation
• Adopt.ai Resources

These resources offer practical tools and guidance for building and deploying AI agents effectively.

Despite having a clear build process, enterprises face significant challenges in wiring and managing the tooling layer.

Next, we’ll explore how Adopt.ai addresses these complexities by automating API discovery, transformation, and orchestration making AI agent development scalable and reliable

Overcoming Tooling Challenges in AI Agent Development with Adopt.ai

The Problem: Manual Wiring and Complexity in the Tooling Layer

Building and managing AI agents at the enterprise level isn’t just about connecting a few APIs. In reality, it’s a time-consuming, complex process. Each new integration often means weeks of manual wiring—studying documentation, mapping endpoints, creating authentication flows, and making sure all data is compatible. Every time an API changes or a downstream dependency updates, workflows can break, requiring more manual fixes.

This leads to:

• Slow development cycles (every API needs to be hand-wired)
• Brittle, fragile workflows (minor changes disrupt automation)
• Limited scalability (managing integrations for many systems becomes overwhelming)
• Poor observability (it’s hard to know what’s breaking and why)
• Questions about compliance and auditability (tracking agent actions manually is unsustainable)

In complex enterprise environments, these manual bottlenecks make it difficult to move beyond small prototypes. This is the core tooling challenge: turning vast, ever-changing APIs into reliable, agent-ready tools at scale.

Two Core Challenges: API Discovery & LLM Readiness

₁. API Discovery

Most enterprises run dozens of SaaS platforms and hundreds of internal services. Which endpoints exist? What are their capabilities? What data models or auth systems govern them?

Discovering the “surface area” of APIs often takes weeks, requiring deep documentation reviews, schema analysis, and trial-and-error testing. Even after discovery, APIs may not be well-described, leaving gaps that stall workflow automation.

2. LLM Readiness

APIs in their raw form are not agent-ready. A POST request with half-documented parameters isn’t something an LLM can automatically turn into a correct tool invocation.

Bridging this gap means translating the API into a usable tool through semantic transformation. This ensures an agent can both understand what the tool does and how to invoke it properly.

From Endpoint to Agent-Ready Tool

Adopt.ai transforms APIs into tools that LLMs can directly call by layering semantic enrichment. The raw endpoint is not enough—agents need a contextualized representation.

The transformation includes:

• Natural Language Description - Adds a human-readable summary of the API’s purpose.

• Use Case Logic  - Defines where the API fits within a business process.

• Parameter Canonization - Standardizes parameters for consistency across workflows.

• ENUMs & Units Alignment  - Normalizes input ranges and units to remove ambiguity.

• I/O Schema - Structures input/output in a schema suited for agent reasoning.

• Entities - Labels domain-specific objects (e.g., Employee, Ticket, Invoice).

• Display Name - Assigns a friendly label usable in tools/UIs.

This semantic layer is what allows an agent to execute a tool call reliably. Without it, orchestration is guesswork.

How Adopt.ai Automates This

Instead of teams spending weeks per endpoint, Adopt.ai automatically:

• Discovers available APIs inside enterprise systems.
• Extracts endpoints and enhances them into Tool Cards with natural language context.
• Canonicalizes parameters and aligns I/O schemas for LLM execution.
• Embeds observability hooks for testing, monitoring, and auditing every call.

This removes dependency on manual wiring and makes scaling agents across dozens of systems achievable.

Example 1: HR Onboarding

Raw Endpoint

POST /v1/workers – Add a new employee in Workday.

Generated Tool Card

{
  "Authorization": "Bearer <token>",
  "Content-Type": "application/json"
}

{
  "firstName": "Jane",
  "lastName": "Doe",
  "email": "jane.doe@company.com",
  "startDate": "2025-10-15",
  "managerId": "M12345",
  "departmentId": "HR01"
}

{
  "workerId": "W67890",
  "status": "created"
}

{
  "error": "Email already exists",
  "code": 409
}
