★ ALWAYS LOAD THIS SKILL BEFORE WRITING ANY CODE. MANDATORY for every coding task:
implementing a feature, fixing a bug, writing a function, debugging, writing/running tests,
building a frontend, starting a service, scaffolding a project, or modifying any codebase.
If the task involves writing or changing code, load this skill FIRST and follow its workflow.
Without it you will skip mandatory verification and the task is NOT complete.
