AI Agent Development: Agents That Finish Tasks, Not Just Answer Questions

Agentic AI in practice: an AI agent reads context, decides what to do, calls your tools and completes a multi-step task, with limits you set. Our AI agent development covers design, build, testing and monitoring, starting with a pilot on one real task. Integration work starts from $1,400. Agentic AI development, AI agent integration and AI agent consulting come from one team.

What we do

What AI agent development includes

An agent is more than a prompt. These are the parts we design so it works reliably in production.

Tool calling

Function calling for LLM agents to your CRM, calendar, database, email and internal APIs, so the agent acts instead of only suggesting.

Orchestration

Multi agent systems: single-agent and multi-agent flows with an AI agent framework such as LangChain, routing and step chaining, chosen by task complexity and not by fashion.

Memory and knowledge

Short-term context and retrieval over your documents with RAG, so answers come from your own sources.

Guardrails and permissions

Autonomous AI agents with limits on what they may do, approval steps and human in the loop (human-in-the-loop) review for risky actions.

Evaluation

Test sets from real cases, accuracy and cost per task, and regression checks before each release.

Observability

Logs of every step and tool call, with alerts when quality or cost drifts.

Why LinkAgency

Why teams build agents with us

Agents fail quietly if they are not tested and limited. We build the safety layer first.

Published starting price

Integration from $1,400 per project, with a written scope and a fixed price after a short assessment.

Controlled autonomy

Each agent has a clear job, limited permissions and a fallback to a person.

Full-stack team

The same engineers build the agent, the integrations and the interface. See web application development.

Measured results

Each agent has a target such as tasks completed, time saved or cost per task.

How we work

How an AI agent project runs

01

Pick one task

We choose a repeatable task with clear inputs, tools and a definition of done.

02

Prototype

A working agent runs on real examples within two to four weeks.

03

Harden

We add guardrails, approvals, evaluation and logging, then integrate with your systems.

04

Release and improve

We launch to a small group, measure results and extend what the agent may do.

Cost and timeline

Agent or simple automation: how to choose

Not every task needs an agent, and AI agent pricing follows that choice. This is the rule of thumb we use.

SituationBest fitWhy
Steps are fixed and predictableWorkflow automationCheaper, faster and easier to test

We start with the simplest design that meets the goal, and add agent behavior only where judgment is needed.

Method

What good agent development looks like in practice

A good agent has a narrow job. We write down the goal, the inputs, the tools it may call and what done looks like. Then we build a loop in which a language model reads the context, picks a tool, observes the result and continues until the task is complete or it asks a person. Prompt design matters, but permissions, validation of tool arguments and clear stop conditions matter more.

People search for this work as custom AI agents, agent builders, AI agent developers or building AI agents for business, and the process is similar: scope, prototype, harden, release. We use mainstream frameworks and an LLM chosen by cost and quality, and we keep the model layer replaceable. For long tasks, state is stored outside the model, and every step is logged so you can audit what the agent did and why. We design the agent architecture around your existing systems, handle system integration and compliance questions up front, and write down the use cases the agent is allowed to handle, so monitoring has a clear baseline.

Typical AI agents examples are support triage, lead qualification, document processing, internal research and reporting. We estimate the cost of AI agents after a short assessment and fix the price in writing, and teams that hire AI agent developers from us get the same engineers from prototype to monitoring. Enterprise AI agents and AI agents for business get the work of a specialised AI agent company with one accountable team. If you only need answers from documents, a chatbot is simpler and cheaper, and we will say so.

Before you ask

Questions we get on the first call

What is AI agent development?

It is the design, building, testing and monitoring of AI agents that use tools and make decisions to complete multi-step tasks within limits you set.

How much does it cost to build an AI agent?

Integration work starts from $1,400 per project. The price of an agent depends on the task, tools and approvals, and we fix it in writing after a short assessment.

What do your AI agent services cover?

Our services cover choosing the task, building the agent with tools and guardrails, testing it on real cases and monitoring it after launch.

Which AI agent examples do you build, and on which platform?

Common AI agent examples are an AI sales agent that qualifies leads and an AI agent for customer support that resolves tickets. We integrate them into your CRM and helpdesk, and choose the AI agent platform or framework by task, cost and privacy.

How is an agent different from a chatbot?

A chatbot answers questions. An agent also takes actions through tools, such as updating a CRM or booking a slot, and decides the steps itself.

Is it safe to let an agent act?

Yes, with limits. We restrict permissions, require approval for risky actions, log every step and keep a person in the loop where needed.

How long does a pilot take?

A working prototype on one task usually takes two to four weeks.

Which models and frameworks do you use?

We choose by task, cost and privacy needs, including private deployments, and keep the model layer replaceable.

How do I start?

Describe the task or ask for the free assessment. You get a scope, a price and a pilot plan, usually within a few days.
