@lvlup-sw/design-invariants

Audit a design proposal or diff against Exarchos's architectural invariants — event-sourcing integrity (INV-1), facade equivalence over shared dispatch core (INV-2), basileus-forward (INV-3), platform-agnosticity (INV-4), agent-first interface design (INV-5a input ergonomics, INV-5b spec-aligned output contract, INV-5c Aspire-inspired control-plane verbs, INV-5d action discriminator pattern), and workflow-agnosticism (INV-6 skills describe behaviors, playbooks describe workflows). Pairs with /axiom:backend-quality — this skill is project-specific (axiom is generic). Do NOT use for: generic backend quality (use /axiom:*), TDD or spec compliance (use /exarchos:review), prose/AI-writing tells (use /axiom:humanize). Triggers: 'check invariants', 'design conformance', 'check #1118 / #1109', or /design-invariants.
