name	miniprogram-development
description	WeChat Mini Program development skill for building, debugging, previewing, testing, publishing, optimizing, and promoting mini program projects. This skill should be used when users ask to create, develop, modify, debug, preview, test, deploy, publish, launch, review, optimize, or promote WeChat Mini Programs, mini program pages, components, `tabBar`, routing, navigation, icon assets, project structure, project configuration, `project.config.json`, `appid` setup, device preview, real-device validation, WeChat Developer Tools Nightly workflows, `wechatide` CLI, WeChat IDE Skills/MCP, console/network debugging, `miniprogram-ci` preview/upload flows, or mini program release processes. It should also be used when users ask about mini program SEO / search optimization / search promotion (小程序 SEO、搜索优化、微信搜索收录、搜索推广、页面收录、关键词排名、被搜索到) or page indexing by the WeChat search crawler (`mpcrawler`). when users explicitly mention CloudBase, `wx.cloud`, Tencent CloudBase, 腾讯云开发, 微信云开发, or 云开发 in a mini program project.

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

Activation Contract

Use this first when

• The request is about WeChat Mini Program structure, pages, preview, publishing, or CloudBase mini program integration.

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 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 or Integration Center generated payment functions -> ../cloudbase-wechat-integration/SKILL.md (official docs: https://docs.cloudbase.net/integration/wechat-pay-miniprogram/index.md)
• UI generation -> ../ui-design/SKILL.md first

Do NOT use for

• Web auth flows or Web SDK-specific frontend implementation.
• WeChat Pay, 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).
• 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).
• Assuming cloud-function return values auto-reply to customer-service chats (must use cloud.openapi.customerServiceMessage.send).
• Making code or configuration changes without first following the Change Safety Protocol (cloudbase-platform/references/protocols/change-safety-protocol.md).
• Performing mini program upload/publish without first completing the checks in cloudbase-platform/references/protocols/deployment-gate.md.

When to use this skill

Use this skill for WeChat Mini Program development when you need to:

• Build or modify mini program pages and components
• Organize mini program project structure and configuration
• Debug, preview, or publish mini program projects
• Work with WeChat Developer Tools workflows
• Handle mini program runtime behavior, assets, or page config files
• Integrate CloudBase in a mini program project when explicitly needed

Do NOT use for:

• Web frontend development (use web-development)
• Pure backend service development (use cloudrun-development or cloud-functions as appropriate)
• UI design-only tasks without mini program development context (use ui-design)

How to use this skill (for a coding agent)

1. Start with the general mini program workflow

   • Treat WeChat Mini Program development as the default scope
   • Do not assume the project uses CloudBase unless the user or codebase indicates it

2. Follow mini program project conventions

   • Keep mini program source under the configured mini program root
   • Ensure page files include the required configuration file such as index.json
   • Check project.config.json before suggesting preview or IDE workflows

3. Route by scenario

   • If the task involves debugging, previewing, publishing, opening DevTools, console/network, or wechatide, read debug and preview reference first
   • If choosing between WeChat IDE Skills and CloudBase MCP, read WeChat IDE Skills vs CloudBase MCP
   • If the task involves CloudBase, wx.cloud, cloud functions, CloudBase database/storage, or CloudBase identity handling, read CloudBase integration reference
   • If the task involves mini program SEO / WeChat search optimization / page indexing / search promotion (小程序搜索优化、页面收录、搜索推广、关键词排名), read Mini Program SEO & WeChat Search Optimization first
   • If the task involves message push (消息推送), customer-service auto-reply (客服消息自动回复), MsgType/Event → cloud function binding, or push-related function logs, read Message Push & Customer Service Auto-Reply first
   • If the task involves tabBar, icon assets, or label spacing, prefer the text-only custom tabBar default below unless the user explicitly requires icons

4. Use CloudBase rules only when applicable

   • CloudBase / 微信云开发 is an important mini program integration path, but not a universal requirement
   • Only apply CloudBase-specific auth, database, storage, or cloud function constraints when the project is using CloudBase

---

WeChat Mini Program Development Rules

General Project Rules

1. Project Structure

   • Mini program code should follow the project root configured in project.config.json
   • Keep page-level files complete, including .json configuration files
   • Ensure referenced local assets actually exist to avoid compile failures

2. Configuration Checks

   • Check project.config.json before opening, previewing, or publishing a project
   • Confirm appid is available when a real preview, upload, or WeChat Developer Tools workflow is required
   • Confirm miniprogramRoot and related path settings are correct

3. Resource Handling

   • For tabBar, prefer a text-only custom tabBar by default when the user does not explicitly need icons. This avoids icon asset handling, removes reserved icon space, and makes the label area easier to align.
   • Only generate local icon assets and configure iconPath / selectedIconPath when the user explicitly asks for tab icons or the design requires them.
   • When generating local asset references such as icons, ensure the files are downloaded into the project.
   • Keep file paths stable and consistent with mini program config files.

Recommended default for simple tabBar

Use tabBar.custom = true, keep only pagePath and text in app.json, and render text-only items in the custom component so there is no icon slot and no extra blank area above the label.

app.json

{
  "tabBar": {
    "custom": true,
    "list": [
      { "pagePath": "pages/index/index", "text": "首页" },
      { "pagePath": "pages/travel/travel", "text": "行程" },
      { "pagePath": "pages/my/my", "text": "我的" }
    ]
  }
}

Keep the custom tabBar layout text-only, and use flex centering or matching height and line-height to remove the blank area above the label. Switch to downloaded local icons only when the user explicitly wants icon-based tabs.

CloudBase as a Mini Program Sub-Scenario

• If the user explicitly uses CloudBase, wx.cloud, Tencent CloudBase, 腾讯云开发, or 云开发, follow the CloudBase integration reference
• In CloudBase mini program projects, use wx.cloud APIs and CloudBase environment configuration appropriately
• Do not apply CloudBase-specific rules to non-CloudBase mini program projects

Debugging, Preview, and Publishing

• Prefer Nightly DevTools + wechatide for open project, compile, simulator, console/network debug, preview, upload, and daily cloud ops (WeChat login — no separate Tencent Cloud login)
• Always pass required context: -c <clientName>, absolute --project, valid appid, and cloud env when needed
• If Nightly / wechatide is not available, use miniprogram-ci as the fallback for preview/upload/npm, and CloudBase MCP for cloud resources; tell the user to install Nightly for full Skills/MCP
• For detailed workflows, read debug and preview reference and WeChat IDE Skills vs CloudBase MCP

Message Push & Customer Service Auto-Reply

微信生态专章：消息推送 / 客服自动回复细节以中文 reference 为准（术语保留英文 API 名）。

• Current only ops path: WeChat Developer Tools IDE + wxide CLI. Do not teach low-level bypasses while cloud_query_msg_push / cloud_manage_msg_push are not yet exposed (track 9109db6b).
• Deploy receiver functions with cloud_fn_deploy and --remote-npm-install; bind (MsgType, Event) → one cloud function in the IDE message-push panel until CLI tools land.
• Customer-service auto-reply requires cloud.openapi.customerServiceMessage.send plus config.json openapi permissions — function return values alone do not reply.
• Function logs: IDE 云开发控制台 → 云函数 → 日志; CLI log query is pending (9109db6b / d5735473).
