code-qualitylisted

This project's code standards. **Full rules in `core/code-quality.md`** (from the project root): read it in full when writing/reviewing code. (Discovery on Codex — this SKILL.md in `.codex/skills/code-quality/`.) In short: - **SRP / no God Objects:** one class — one responsibility; "And" in a name and >10 public methods → split; crossing the LOC threshold → a signal: justify cohesion OR split (not the verdict itself); a confirmed God Object → split. - **Layers are one-directional:** dependencies flow one way only, reverse imports are forbidden. - **No TODO/FIXME and no commented-out code** — do it now or file a task; git remembers history. - **Errors** are typed, never swallowed silently; no empty catch blocks. - **Security minimum:** no secrets in code/logs; user input only through prepared statements / sanitization. - **Readability > "cleverness":** simple and explicit beats clever; optimizations without a benchmark are forbidden. - LOC limits and test rules are in `core/quality-gates.md`. - **When NOT to:** not for debugging something broken (→ `debugging`) and not for choosing an architecture (→ architect/panel) — this is writing/review standards, not root-cause finding or a structural decision.
