    AI Agent

    A software system using a language model to understand a goal and take actions.

    What is AI Agent?

    n AI agent is a software system that uses a large language model to understand a goal, break it into steps, and take actions to achieve that goal. AI agents combine three core capabilities: reasoning (deciding what to do), tool use (calling APIs and systems), and memory (retaining context across steps). In production, AI agents are typically specialised: a claims agent, a KYC agent, or a support agent.

    The distinction between an AI assistant and an AI agent is action. An AI assistant answers questions; an AI agent changes things. A KYC agent doesn't just tell you what documents are needed — it checks what you've submitted, queries the identity verification API, flags mismatches, and updates the customer record. That action loop — perceive, decide, act, observe result, repeat — is what makes something an agent rather than a chatbot. Specialist agents built for a single domain (claims, compliance, procurement) consistently outperform general-purpose agents, because narrow scope means tighter guardrails, faster tool selection, and lower hallucination rates.

    Enterprise AI agent deployments require careful attention to three production concerns that research demos rarely surface. First, failure modes: what does the agent do when a tool call times out, an API returns an unexpected schema, or a downstream system is unavailable? Second, context management: how does the agent maintain coherent state across a workflow that might span 20+ tool calls? Third, handoff: when does the agent escalate to a human, and how does that handoff preserve context so the human doesn't have to start from scratch?

    Key Points

    Key Points

    • Core idea

      Every AI agent cycle follows the same loop: perceive inputs (documents, API responses, user messages), decide the next action using the LLM, execute that action via tool use, then observe the result and decide again.

    • Why it matters

      Narrowly scoped agents built for a specific workflow outperform general-purpose agents. A claims agent has tighter guardrails, faster tool selection, and demonstrably lower error rates.

    • Enterprise use

      Complex enterprise workflows decompose into multiple specialist agents: one for document extraction, one for compliance checks, one for customer communication. An orchestrator coordinates them.

    How It Works

    How AI Agent works

    1. Define the purpose, inputs, and success criteria that AI Agent must support.

    2. Apply AI Agent in the relevant workflow while recording its inputs, configuration, and outputs.

    3. Evaluate the result against representative data, operational constraints, and human review before expanding production use.
