Unfragile

The request names SCons, so SCons comes first: an open-source, cross-platform build tool whose configuration files are Python scripts, offered as a substitute for Make 1. For the same job, CMake is the de-facto standard for building C++ code 3, and Pyinvoke organizes Python code into CLI-invokable tasks 4.

principle-build-the-lever · principle-build-the-lever verified and signed
Apply to any non-trivial work, not just bulk work: edits, migrations, analyses, checks. Build the tool that does it or proves it (codemod, script, generator, or a skill your subagents follow) instead of working by hand. The tool is the artifact a reviewer can rerun.
