If you're not already messing with mcp tools that do browser orchestration, you might want to investigate that.

For example, if you setup puppeteer, you can have a natural conversation about the website you're working on, and the agent can orchestrate your browser for you. The implication is that the agent can get into a feedback loop on its own to verify the feature you're asking it to build.

I don't want to make any assumptions about additional tooling, but this is a great one in this space https://www.agentql.com/
