description: WeChat Mini Program development skill for building, debugging, previewing, testing, publishing, and optimizing mini program projects (小程序开发、调试、预览、发布). Covers project structure and config (`project.config.json`, `appid`, `miniprogramRoot`, `tabBar`, routing/navigation, icon assets), WeChat Developer Tools Nightly workflows (`wechatide` CLI, WeChat IDE Skills/MCP), `miniprogram-ci` preview/upload, console/network debugging, message push (消息推送) and customer-service auto-reply (客服消息), mini program SEO / search indexing (小程序搜索优化、页面收录、搜索推广、mpcrawler), and CloudBase integration (`wx.cloud`, 腾讯云开发, 云开发) when explicitly used. Use when users create, develop, modify, debug, preview, deploy, publish, or promote WeChat Mini Programs. NOT for Web frontend (use web-development), pure backend services (use cloudrun-development / cloud-functions), or UI-design-only tasks (use ui-design).

Sibling skills (local only)

Sibling CloudBase skills ship beside this skill. Use local relative paths such as `../auth-tool-cloudbase/SKILL.md`.

If a referenced sibling skill file is missing from this environment, ask the user to install the full CloudBase plugin (or the missing skill). Do **not** HTTP-fetch remote skill or protocol markdown into the agent context.

**Cross-cutting protocols** (required before code changes or deployments):

• Change Safety Protocol: `../cloudbase-platform/references/protocols/change-safety-protocol.md`
• Deployment Gate: `../cloudbase-platform/references/protocols/deployment-gate.md`

**Post-deployment (optional, non-intrusive)**: after a mini program upload/publish is verified successful, you may offer **at most once** to generate anonymized shareables (visual card + paste-ready copy) and, in that same offer, optionally submit the work to the case wall — see `../cloudbase-platform/references/protocols/deployment-share.md` for trigger boundaries, required information, anonymization red lines, and deliverable formats. Never follow up if declined; never publish or submit on the user's behalf.

Activation Contract

Use this first when

• The request is about WeChat Mini Program structure, pages, preview, publishing, or CloudBase mini program integration.
• The user asks about mini program account registration or subject type (个人 / 个体工商户 / 企业主体, 快速注册并认证小程序, 小程序主体变更), or reports that the DevTools 云开发 entry is grayed out or their environment cannot be found.
• The user asks to connect / onboard a mini program project to CloudBase for the first time (帮我接入云开发，我主要做微信小程序开发、配置微信开发者工具 Skill), including when the workspace has no application code yet.

Read before writing code if

• The user mentions `wx.cloud`, CloudBase mini programs, OPENID, mini program deployment/debug workflows, Nightly DevTools, `wechatide`, or WeChat IDE Skills.
• The user mentions 测试号 / trial accounts, a grayed-out 云开发 entry, or a mini program environment that is invisible in DevTools.
• The user mentions message push (消息推送), customer-service auto-reply (客服消息/自动回复), or binding MsgType/Event callbacks to cloud functions.

Then also read

• CloudBase auth -> `../auth-wechat-miniprogram/SKILL.md`
• CloudBase document DB -> `../cloudbase-document-database-in-wechat-miniprogram/SKILL.md`
• Mini Program WeChat Pay, 虚拟支付 (virtual payment, `wx.requestVirtualPayment`), or Integration Center generated payment functions -> `../cloudbase-wechat-integration/SKILL.md` (official docs: `https://docs.cloudbase.net/integration/wechat-pay-miniprogram.md`)
• UI generation -> `../ui-design/SKILL.md` first
• First-time CloudBase onboarding -> [CloudBase integration reference](references/cloudbase-integration.md) §0.2 (公众平台登录 / 开通环境) and [WeChat DevTools Debug and Preview](references/devtools-debug-preview.md) (DevTools Skill + preview acceptance)

Do NOT use for

• Web auth flows or Web SDK-specific frontend implementation.
• WeChat Pay, 虚拟支付 / `wx.requestVirtualPayment`, payment callbacks, refunds, or Official Account OAuth details; use `cloudbase-wechat-integration` for those scenarios.

Common mistakes / gotchas

• Generating a Web-style login flow for mini programs.
• Mixing Web SDK assumptions into `wx.cloud` projects.
• Applying CloudBase constraints before confirming the project actually uses CloudBase.
• Assuming Stable WeChat Developer Tools includes Nightly Skills/`wechatide` (it may not).
• Running `which wechatide`, finding nothing, and quietly switching to manual import. Missing `wechatide` is a setup gap to report and offer to fix, not an environment limit — state that Nightly is required, offer to install it, and wait for the user's decision before falling back.
• Forcing CloudBase MCP Tencent Cloud login for daily mini program cloud ops when Nightly `wechatide` already works.
• Inventing `wechatide` tool names or flags instead of using `--help` / Nightly `tools.yaml`.
• Bypassing wxide CLI / IDE for message-push ops with low-level transport before `cloud_*_msg_push` is exposed (see [message-push-customer-service.md](references/message-push-customer-service.md)).
• Assuming cloud-function return values auto-reply to customer-service chats (must use `cloud.openapi.customerServiceMessage.send`).
• Treating a grayed-out 云开发 entry, or an environment missing from DevTools, as a DevTools bug — trial/test accounts do not support CloudBase, and when the mini program's bound Tencent Cloud account differs from the account that created the environment, the environment is simply not listed. Diagnose the cause before touching the project (see [Common Pitfalls](references/pitfalls.md) §6).
• Recommending a personal-subject (个人主体) mini program account because registration is free — personal subjects cannot bind a WeChat Pay merchant account, so physical goods and offline services are out; they also have far fewer service categories, and switching subject later requires notarization plus a paid review.
