Continue (Mission Control) - Quality control for your software factory

AI agents multiplied code output. Review didn't scale with it. Tests still pass, but conventions erode, security patterns slip, and your codebase starts feeling like it was written by ten different people. Continue is quality control for your software factory: source-controlled AI checks on every pull request. Describe a standard in plain English, commit it as a markdown file, and it runs as an AI agent on every PR. Catches what you told it to. Passes silently when everything's fine.
