Art & Design

Creates reusable Zod v4 schemas, validates API payloads, forms, and configuration input, transforms and coerces data safely, and handles validation errors with strong type inference for TypeScript applications. Use when designing validation layers, parsing `z.string()`, `z.object()`, or `z.email()` schemas, or implementing runtime type-safe data validation.

把"大到塞不进单个 feature"的需求做成完整事前规划：概设 + 接口契约 + 子 feature 拆解清单，放在 `.codestable/roadmap/{slug}/`。两种模式 new / update。触发：用户说"我想要一个 X 系统"、"帮我把这块需求拆一下"、"开一份 roadmap"，或 feature-design 阶段发现需求太大。

Export Canva designs without watermarks in high resolution with all elements intact

把可复用的编程模式 / 库用法 / 技术技巧整理成处方性参考库，三种类型 pattern / library / technique。触发：用户说"记录一个技巧"、"这个用法值得记"、"tricks"、"记录库用法"，或 design / analyze 阶段发现值得沉淀的技巧时推送。

Create high-quality, production-grade skills for Claude Code. Expert guidance on skill architecture, workflow design, prompt engineering, and packaging. Use when user wants to create a new skill, build a skill, design a skill, write a skill, update an existing skill, improve a skill, refactor a skill, debug a skill, or package a skill. Triggers: 'create skill', 'build skill', 'new skill', 'skill creation', 'write a skill', 'make a skill', 'design a skill', 'improve skill', 'package skill', 'skill development', 'skill template', 'skill best practices', 'write SKILL.md'.

Connects Figma design components to code components using Code Connect mapping tools. Use when user says "code connect", "connect this component to code", "map this component", "link component to code", "create code connect mapping", or wants to establish mappings between Figma designs and code implementations. For canvas writes via `use_figma`, use `figma-use`.

feature 流程的超轻量通道——不写 design / checklist 直接动手，但先指引 AI 查 CodeStable 知识库再开工。触发：用户说"快速模式"、"fastforward"、"别那么多步骤"、"直接开干"，且需求小到不值得走 design 流程。

把已拍板的技术选型、架构决定、长期约束、编码规约记成永久性决策文档（tech-stack / architecture / constraint / convention 四种）。触发：用户说"记录决定"、"归档技术选型"、"ADR"、"记录这条约束"、"把规约写下来"，或 design / analyze 后做出重要选择。只归档已拍板的，讨论中的不归档。

Tailwind CSS v4 principles. CSS-first configuration, container queries, modern patterns, design token architecture.

Headless UI for virtualizing large element lists at 60FPS in TS/JS, React, Vue, Solid, Svelte, Lit & Angular.

CRITICAL: Use for type-driven design. Triggers: type state, PhantomData, newtype, marker trait, builder pattern, make invalid states unrepresentable, compile-time validation, sealed trait, ZST, 类型状态, 新类型模式, 类型驱动设计

新功能开发的子流程入口，把"加个 X 能力"从想法走到验收闭环。触发：用户说"做新功能"、"加个 X"、"实现 XX"。只做路由，根据已有产物决定走 brainstorm / design / fastforward / implement / acceptance。不处理 bug。

Designs and implements backend systems including REST APIs, microservices, database architectures, authentication flows, and security hardening. Use when the user asks to "design REST APIs", "optimize database queries", "implement authentication", "build microservices", "review backend code", "set up GraphQL", "handle database migrations", or "load test APIs". Covers Node.js/Express/Fastify development, PostgreSQL optimization, API security, and backend architecture patterns.

代码优化的子流程入口，处理"行为不变、结构变"的工作（结构 / 性能 / 可读性），按 scan → design → apply 分步执行每步人工放行。触发：用户说"优化一下 / 重构 / 重写 / 拆一下 / 性能不行 / 代码太长"且不夹带行为改动。不处理新需求 / bug / 跨模块架构重划。

feature 流程阶段 2——按 {slug}-checklist.yaml 里 design 切好的 paradigm 维度 steps 推进，每步具体改哪个文件由 implement 自决，写完用统一格式汇报。触发：用户说"方案确认了开始实现"、"按方案写代码"、"开工"。前提是 design 已 approved 且有 checklist。遇到方案外情况要回方案谈不要硬冲。

MUST activate when the project contains a uiBundles/*/src/ directory and scaffolding a new UI bundle or app, or when editing ui-bundle.json, .uibundle-meta.xml, or CSP trusted site files. Use this skill when scaffolding with sf template generate ui-bundle, configuring ui-bundle.json (routing, headers, outputDir), or registering CSP Trusted Sites. Activate when the task involves files matching *.uibundle-meta.xml, ui-bundle.json, or cspTrustedSites/*.cspTrustedSite-meta.xml.

feature 流程阶段 1——为新功能起草 {slug}-design.md 作为后续实现和验收的唯一输入，拍板后抽出 checklist。触发：用户说"开始设计方案"、"写 design doc"、"准备实现 XX"，前提是已知道做什么、为谁、怎么算成功。

想法还模糊时的讨论入口，做分诊后路由到 feature-design / feature-brainstorm / roadmap。AI 是思考伙伴不是记录员。触发：用户说"有个想法还没想清楚"、"先 brainstorm 一下"、"聊一聊这块"、"方向还在摇摆"。不处理 bug 和重构。

feature 流程阶段 3——验收闭环：对照 design 核实现 + 回写 architecture / requirement / roadmap，最后产出 {slug}-acceptance.md。触发：用户说"功能写完了验收一下"、"做最后检查"、"准备 merge"、"出验收报告"。前置依赖 cs-feat-impl 完成。

Guide for authoring Apollo Federation subgraph schemas. Use this skill when: (1) creating new subgraph schemas for a federated supergraph, (2) defining or modifying entities with @key, (3) sharing types/fields across subgraphs with @shareable, (4) working with federation directives (@external, @requires, @provides, @override, @inaccessible), (5) troubleshooting composition errors, (6) any task involving federation schema design patterns.

React Testing Library: user-centric component testing with queries, user-event simulation, async utilities, and accessibility-first API. Use when writing React component tests, selecting elements by role/label/text, simulating user events, or testing async UI behavior. Keywords: React Testing Library, @testing-library/react, user-event, queries, render.

Use when medium-to-large changes need explicit requirements, technical design, and task planning before implementation, especially for multi-module work, unclear acceptance criteria, or architecture-heavy requests.

Orchestrate iOS screenshot automation with xcodebuild/simctl for build-run, AXe for UI actions, JSON settings and plan files, Koubou-based framing (`asc screenshots frame`), and screenshot upload (`asc screenshots upload`). Use when users ask for automated screenshot capture, AXe-driven simulator flows, frame composition, or screenshot-to-upload pipelines.

Generates sustainability-focused guidance for Google Cloud workloads based on the design principles and recommendations in the Google Cloud Well-Architected Framework (WAF). Use this skill to evaluate a workload, identify environmental impact requirements, and provide actionable recommendations to build, deploy, and manage the workload sustainably in Google Cloud.
