Frontend

Guide logging practices based on Dave Cheney's minimalist philosophy. Use when adding log.Info/Debug/Error/Warn/Fatal calls, reviewing logging code, handling errors with log+return pattern, discussing log levels, or designing error handling strategies.

Guide structural code improvements using Kent Beck's Tidy First methodology. Use when seeing messy code, before making behavioral changes, after completing features, or discussing when to clean up code.

Build conversational AI agents using Vercel AI SDK + OpenRouter. Use when creating Next.js frontends with streaming UI, tool calling, and multi-provider support.

Standardize authentication and persistent memory storage using Supabase PostgreSQL. Use when building SaaS apps that need user auth, cross-device sync, and conversation history.

Guide code refactoring using Martin Fowler's catalog of behavior-preserving transformations. Use during TDD REFACTOR phase, when code smells are detected (duplication, long methods, feature envy), when discussing structural improvements, or before behavioral changes (Tidy First).

Build conversational AI agents using Pydantic AI + OpenRouter. Use when creating type-safe Python agents with tool calling, validation, and streaming.

Use when receiving code review feedback (especially if unclear or technically questionable), when completing tasks or major features requiring review before proceeding, or before making any completion/success claims. Covers three practices - receiving feedback with technical rigor over performative agreement, requesting reviews via code-reviewer subagent, and verification gates requiring evidence before any status claims. Essential for subagent-driven development, pull requests, and preventing false completion claims.

Build OpenAI Apps SDK applications - interactive ChatGPT apps with MCP servers, React widgets, and rich UI components for conversational experiences

Apply structured, reflective problem-solving for complex tasks requiring multi-step analysis, revision capability, and hypothesis verification. Use for complex problem decomposition, adaptive planning, analysis needing course correction, problems with unclear scope, multi-step solutions, and hypothesis-driven work.

Internal skill. Use cc10x-router for all development tasks.

Create distinctive, production-grade frontend interfaces with high design quality. Use this skill when the user asks to build web components, pages, or applications, OR when they provide screenshots/images/designs to replicate or draw inspiration from. For screenshot inputs, extracts design guidelines first using ai-multimodal analysis, then implements code following those guidelines. Generates creative, polished code that avoids generic AI aesthetics.

Frontend UI/UX design intelligence - activate FIRST when user requests beautiful, stunning, gorgeous, or aesthetic interfaces. The primary skill for design decisions before implementation. 50 styles, 21 palettes, 50 font pairings, 20 charts, 8 stacks (React, Next.js, Vue, Svelte, SwiftUI, React Native, Flutter, Tailwind). Actions: plan, build, create, design, implement, review, fix, improve, optimize, enhance, refactor, check frontend UI/UX code. Projects: website, landing page, dashboard, admin panel, e-commerce, SaaS, portfolio, blog, mobile app, .html, .tsx, .vue, .svelte. Elements: button, modal, navbar, sidebar, card, table, form, chart. Styles: glassmorphism, claymorphism, minimalism, brutalism, neumorphism, bento grid, dark mode, responsive, skeuomorphism, flat design. Topics: color palette, accessibility, animation, layout, typography, font pairing, spacing, hover, shadow, gradient.

Create a new React component following Lab's architecture patterns. Determines component scope (core vs. page-scoped), generates proper structure with TypeScript types, creates Storybook stories for core components, and ensures composability with existing components.

Copilot agent for cloud architecture design, AWS/Azure/GCP configuration, IaC code generation (Terraform/Bicep), and cost optimization Trigger terms: cloud architecture, AWS, Azure, GCP, cloud infrastructure, IaC, Terraform, CloudFormation, cloud design, serverless, cloud migration Use when: User requests involve cloud architect tasks.

Internal skill. Use cc10x-router for all development tasks.

software-developer skill Trigger terms: implement, code, development, programming, coding, build feature, create function, write code, SOLID principles, clean code, refactor Use when: User requests involve software developer tasks.

Internal skill. Use cc10x-router for all development tasks.

Validates complete requirements traceability across EARS requirements → design → tasks → code → tests. Trigger terms: traceability, requirements coverage, coverage matrix, traceability matrix, requirement mapping, test coverage, EARS coverage, requirements tracking, traceability audit, gap detection, orphaned requirements, untested code, coverage validation, traceability analysis. Enforces Constitutional Article V (Traceability Mandate) with comprehensive validation: - Requirement → Design mapping (100% coverage) - Design → Task mapping - Task → Code implementation mapping - Code → Test mapping (100% coverage) - Gap detection (orphaned requirements, untested code) - Coverage percentage reporting - Traceability matrix generation Use when: user needs traceability validation, coverage analysis, gap detection, or requirements tracking across the full development lifecycle.

technical-writer skill Trigger terms: documentation, technical writing, API documentation, README, user guide, developer guide, tutorial, runbook, technical docs Use when: User requests involve technical writer tasks.

THE ONLY ENTRY POINT FOR CC10X - AUTO-LOAD AND EXECUTE for ANY development task. Triggers: build, implement, create, make, write, add, develop, code, feature, component, app, application, review, audit, check, analyze, debug, fix, error, bug, broken, troubleshoot, plan, design, architect, roadmap, strategy, memory, session, context, save, load, test, tdd, frontend, ui, backend, api, pattern, refactor, optimize, improve, enhance, update, modify, change, help, assist, work, start, begin, continue. CRITICAL: Execute workflow. Never just describe capabilities.
