Orthotect: Deterministic Interface Engineering & Runtime Gates for AI Coding Agents

#webdev #ai #css #opensource

AI coding assistants (Claude Code, Cursor, Codex, Antigravity) are revolutionizing frontend engineering, but they often produce accessibility violations, hardcoded pixel values, broken RTL/BiDi layouts, and flaky UI states.

Orthotect is a deterministic interface engineering runtime and quality gate architecture built to force AI coding agents to generate rock-solid, production-grade UI code.

Orthotect is an enterprise-grade interface engineering runtime built to enforce deterministic architectural quality gates, automated code review audit, state machine rigor, and aesthetic diversification onto autonomous AI coding agents (Antigravity CLI agy, Claude Code, Cursor Agent, OpenAI Codex, and Grok Build).

Unlike prompt-only libraries that merely request "clean modern UI", Orthotect provides a mathematical token foundation, Finite State Machine (FSM) deadlock reachability, auto-healing in-place remediation (--fix), technical SEO schema engineering, Core Web Vitals layout shift…

🏛️ The 4 Non-Negotiable Pillars of Orthotect

  1. Deterministic Design Tokens (DTCG): Enforces 3-tier token architecture (Primitives -> Semantics -> Components) with zero arbitrary color or spacing values.
  2. True Bidirectional Symmetry (BiDi): Eliminates left/right hardcoding in favor of standard CSS Logical Properties (inline-start, padding-block, etc.) for seamless Arabic (RTL) & English (LTR) rendering.
  3. WCAG 2.2 AAA Contrast & Accessibility Gates: Automated AST inspection verifying minimum contrast ratios, focus rings, keyboard navigability, and ARIA roles.
  4. Finite State Machine (FSM) Component Integrity: Guards interactive forms against double-submission races and unhandled async error states.

🛠️ Integrating with AI Agents

Orthotect provides automated linting scripts and system prompt guardrails that plug directly into agent workflows:

# Run deterministic design QA gates
orthotect lint --wcag-level=AAA --tokens=dtcg.json ./src/components
