AI agent

An AI agent is a system in which a language model decides its own next steps and uses tools, such as search, a CMS or a code editor, to complete a task. A fixed AI workflow, by contrast, follows steps a developer wrote in advance.

An agent is a language model running in a loop with tools. It gets a task, decides what to do first, calls a tool such as a search, a database query or a file edit, looks at the result and decides the next step, until the task is done or it needs help. Anthropic draws the line this way: workflows run models and tools through predefined code paths, while agents direct their own process and tool use.

Tools are what make an agent useful. Protocols such as the Model Context Protocol give agents a standard way to connect to systems like a CMS, an analytics account or a code repository. Anthropic’s advice is to start with the simplest setup that works and add agent autonomy only where a fixed sequence of steps falls short.

Why it matters for a SaaS company

Agents are changing two things. Inside the company, marketing teams can ask an agent for a new landing page, a CMS update or a weekly traffic report instead of waiting on a developer. In the product, more SaaS tools ship agent features of their own, which raises design questions about review, undo and trust. In both cases the quality of the output depends less on the model than on what the agent works with: a clean design system, a structured CMS and clear permissions.

How DesignMe handles it

We set up AI workflows where a team asks an agent in Slack or Claude for pages, content and reports. We prepare the foundations first: component and section rules, the CMS content model and a brand and tone guide, so drafts come out on brand. Connections are scoped, with separate rights to read, draft, publish and approve, and every action is logged. Every change comes back with a preview link, and nothing goes live until someone on the team approves it. We run our own site this way: it is built in Astro and edited with Claude, and each change is reviewed before it ships. On code-based sites the agent edits files and opens a pull request; on Webflow it works through the official MCP server, as we compare in Astro vs Webflow.

Example

Say a head of marketing asks in Slack for a landing page for an upcoming webinar. The agent reads the event details, builds the page from approved sections in the design system, writes the copy in the brand tone and posts a preview link in the thread. She asks for a shorter headline, the agent updates it, and her approval publishes the page.

Common mistakes

  • Starting with the agent. Without a component system and content model, drafts look generic and need heavy fixing.
  • Too much access. An agent that can publish everything can break everything. Scope permissions to the job.
  • No review step. Agents state wrong things confidently. Keep a human approval before anything goes live.
  • Automating rare tasks. Pick requests your team makes every week, not edge cases.

Questions

What is the difference between an AI agent and a chatbot?
A chatbot answers in the conversation. An agent takes actions: it can call tools, read and write files, update a CMS or open a pull request, and decide which step to take next based on what it finds. Many products now combine both, with a chat window in front of an agent.
Is it safe to let an AI agent change our website?
It can be, with the right guardrails. Give the agent only the access the task needs, separate drafting from publishing, show every change as a preview or pull request, and log what it did. Agents still make mistakes, so a person should approve anything that goes live.
