Harness-agnostic standards, skills, and rules for AI coding agents. Generated from skills/ — see scripts/build-claude.sh.

Cross-stack engine. engine (how the agent works on every task: focus, tiered planning, honesty with file:line evidence, minimize-code, always-on security/testing/observability rules), verify-changes (adversarial verification before done + on-demand audits), standards-config (standards.json schema).

Flutter-specific standards — engineering (Dart, widget rules, data layer, api-data patterns), accessibility (Semantics, screen readers, touch targets), performance (DevTools, frame budget, const widgets), forms, observability, production-readiness. app-audit (full Flutter audit: pre-ship checks + design quality + screen states). Pair with mobile-standards + design-standards for the design contract.

Mobile pack — one design skill: Tier-1 HIG/Material/WCAG R-rules with per-framework token greps, plus mobile-specific rules (tabs, haptics, platform conventions, navigation continuity). Applies to Flutter, React Native, SwiftUI, Jetpack Compose. Install design-standards alongside — it owns the shared contract (design-system).

API pack — NestJS + Prisma. Auto-invoke: nestjs (layering, DTO validation, error shape, config, production-concern audit via Detect → Check → Suggest, Prisma schema-change workflow) + api-design (REST semantics, pagination, errors), cross-stack-contracts (active when standards.json stacks has 2+ entries), websockets (conditional on socket.io/ws usage).

Web pack — Next.js + Tailwind + shadcn. Auto-invoke: nextjs + production-readiness + design (Tier-1 WCAG/CSS R-rules + responsive, chrome, theming, aesthetic coherence) + performance; i18n (conditional). Commands: pre-ship (full gate; narrow with 'design' or 'theme'), extract-tokens, aesthetic-coherence — audits delegate to core-standards:verify-changes. Install design-standards alongside — it owns the shared contract (design-system).

Platform-agnostic design pack — one skill: design-system, the shared contract for Web, iOS, and Android. Tokens, spacing, type scale, color, elevation, radius, states, motion, dark mode, density, iconography, microcopy, accessibility (WCAG 2.2 AA + ARIA/Swift/Compose map), information architecture, perceptual PASS/FAIL rules.
