unclebob/ub-mode is a skill for coding agents created by Uncle Bob. It guides you to implement code step by step when writing or changing code, and to follow test-driven development (TDD) and root-cause-oriented fixes. Because the repository does not record the latest release or version information, this post does not introduce the changes of any specific version. Based on the README and the skill documentation, you can look at the way of working and the scope proposed by this repository.
The core is to first make code that works, and then refine it properly. The guidance also recommends fixing root causes and working in verifiable units of work. Quality checks that measure complexity, duplication, and mutation testing are left to separate tools, and the skill documentation guides you to use these tools together. Installation consists of copying the technical document into the agent's technical directory and then invoking it. So rather than directly providing inspection features, this repository bundles the rules an agent should follow and how to use external tools.
The center of the repository is not executable code but a single technical document. The provided information does not present results for complexity, duplication, or mutation testing, nor their effect on actual code quality, and the license and primary language are not recorded either. It is therefore more accurate to view these guidelines as material that organizes working principles rather than a tool that verifies the implementation itself. Whether the rules translate into code quality can only be judged with results from separate inspection tools.
