Use this skill when you develop, design, build, deploy, debug, migrate, or troubleshoot CloudBase (腾讯云开发, 云开发, TCB, 微信云开发) projects — Web, 微信小程序, 小程序, uni-app, mobile (iOS, Android, Flutter, React Native). Covers UI (页面, 界面, 表单, dashboard, prototype, 原型); auth (登录, 注册, OAuth, publishable key); databases (NoSQL 文档数据库, MySQL 关系型数据库, PostgreSQL/CloudBase PG, app.rdb(), queryPgDatabase/managePgDatabase, CRUD, security rules); 云函数/cloud functions (serverless, scf_bootstrap); CloudRun (云托管, Dockerfile); 云存储; built-in AI (内置大模型, AI 对话, streaming, 流式输出, 图片生成, generateText, streamText, createModel, generateImage, TokenHub, Hunyuan, DeepSeek, GLM, Kimi, Token Credits 资源包, 小程序成长计划); third-party/custom model onboarding (第三方大模型接入, 大模型调用, LLM API); AI agent (智能体, AG-UI, LangGraph); ops troubleshooting (巡检, 诊断, 日志); spec workflow (需求文档, 技术方案, requirements, tasks.md). Do NOT use for non-CloudBase projects, pure frontend without CloudBase, or self-hosted backends without CloudBase.

Use this skill when a browser/Web app (React, Vue, Next, Nuxt, static sites, SPAs, dashboards, AI chat UI, 页面, 前端, 网页) needs AI models via @cloudbase/js-sdk. Default routing for Web/frontend AI — call directly from the browser, do NOT propose a Node.js proxy. Covers generateText and streamText; models via ai.createModel with groups cloudbase, hunyuan-exp, or custom-*, model id in the `model` field. MUST run two-step preflight before code — see body. NOT for Node.js backend (use ai-model-nodejs), Mini Program (use ai-model-wechat), or image generation (Node SDK only).

Coordinator-routed implementation guidance for confirmed Laravel 11 or 12 repositories when framework conventions materially own the work. Use after project-development-mindset inspects laravel/framework, or directly when explicitly invoked or installed standalone. Never load both Laravel version skills; Laravel 12-to-13 upgrades use the Laravel 13 skill. Do not use merely for supporting Sail, Docker, test, or frontend commands.

Judge whether a market FAILED to react to news favorable to a crowded speculative position — step 2 of Jason Shapiro's COT contrarian process. Consumes a cot-contrarian-detector report (or an explicit direction) plus a Claude-curated events JSON, fetches the underlying price series with a documented fallback chain, and produces a fail-closed CONFIRMED / NOT_CONFIRMED / INSUFFICIENT_EVIDENCE verdict using a statistically validated drift-significance test (not a naive failure-ratio, which false-confirms on pure noise). Generic beyond COT — reusable for PEAD and macro-crowding news-failure checks. Use when the user asks to check news-failure confirmation, whether a crowded market "shrugged off" good/bad news, or wants to run Shapiro step 2 on a CROWDED_LONG/CROWDED_SHORT market.

MUST activate whenever a uiBundles/*/src/ project reads, writes, or displays Salesforce data — INCLUDING building a page, list, table, card grid, dashboard, or form that shows, filters, counts, or edits records of any object (e.g. Property__c, Account, Case), even when the prompt names only the UI or the object and never says query, GraphQL, or SDK. Records behind such a component come from Salesforce, so use this ALONGSIDE experience-ui-bundle-frontend-generate: that skill styles the component, this one wires its data. Also triggers on @salesforce/platform-sdk imports, sdk.graphql.query / mutate / sdk.fetch calls, *.graphql files, or stale data needing force-refresh. New read/write work uses the current @salesforce/platform-sdk API; migrate only EXISTING old @salesforce/sdk-data callable code. Not for pure styling/layout with no records, app shell, file upload, or auth/search scaffolding. DO NOT TRIGGER for OAuth, object/field schema changes, Bulk/Tooling/Metadata API, or declarative automation.
