# 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. - 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. - Outside any command: apply this checklist as the primary engineering quality reference. ## Severity rubric Severity rubric matches `rules/markdown-report.md`: cite on findings, do not invent new levels. ## 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 docs or specs | Requirements clarity | | Deciding extract / test / commit / refactor | De
