Put your LLM output under test, or every prompt tweak is a silent regression

In our platform, we run a multi-step AI agent that generates content for customers in the sports world. The agent is never fixed: we change the underlying models, reword prompts, restructure workflow steps, adjust the agent logic. Any of those can quietly make the output worse, and for a while the only safeguard was a human, reading generated content and forming an opinion. That doesn’t scale at all, highly subjective and misses slow drift completely. ...

The biggest shift for me was not just that AI tools became better, but that my role started changing around them: from writing more code myself to organizing work, context, quality, and small agent-driven workflows.

Writing Slack bot with ChatGPT as a coding assistant

As an engineer always on the lookout for new tools and technologies, I recently set myself an interesting challenge: to build something useful with GPT-4 as a coding assistant, writing as little code as possible manually. There was a need for a specific kind of bot within our team. With numerous Git repositories spread across various GitLab groups, having a bot to to remind us about merge requests waiting for review was becoming essential. That’s how the idea of the Mergentle Reminder bot came up. By the way, I came up with the name without the help of ChatGPT and I am very proud of it 😄. ...
