# Engineering fundamentals Foundation reference for engineering work. Loads alongside language and framework skills for any review, audit, plan, implementation, refactor, or code quality task. The `/flow:*` and `/audit:*` commands enforce these checks as deterministic phase gates at the right moment. When inside one of those commands, defer to the command's enforcement and apply only the sections relevant to ad-hoc questions that arise during execution. When outside any command, apply this checklist as the primary engineering quality reference. ## Severity rubric Severity rubric matches `markdown-report`: cite on findings, do not invent new levels. - `failure`: a concrete defect or violation that should not ship. - `warning`: a smell or pattern that compounds with other findings. - `info`: a hardening opportunity or note, not a defect. ## When to load this skill | Activity | Sections to apply | | ----------------------------------- | --------------------------------------------------------- | | Reviewing someone else's PR or diff | Code-level integrity, Test design, Metric thresholds, V&V | | Planning a change ad-hoc | Requirements clarity, Design integrity | | Writing code without a plan | Code-level integrity | | Triaging a "this feels wrong" hunch | Metric thresholds, V&V | | Sanity-checking
