Use this skill when users request “微信监听” (WeChat monitoring), “消息提取” (message extraction), “Agent 开发” (Agent development), “wxauto”, “Accessibility API”, “UI 自动化” (UI automation), “输入框控制” (input field control), or “Platform Agent”, or mention “微信自动化” (WeChat automation), “消息监控” (message monitoring), or “WeChat monitoring”. Use it to develop WeReply’s Platform Agent (Windows wxauto or macOS Accessibility API), implement WeChat message monitoring and extraction, input field control, and Agent error handling.
Enterprise-grade access control patterns to prevent broken access control, IDOR, tenant data leaks, privilege escalation, and admin route exposure. Covers RBAC, ABAC, ownership checks, multi-tenant scoping, policy middleware, row-level security, and audit logging for Node.js, Cloudflare Workers, Laravel, and Python.

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.
How to work in a Codebase Wiki project (the `codebase-wiki` starter pack): an agent-authored, source-grounded wiki of the surrounding codebase. Read when the project has a `wiki/` knowledge base with `architecture/`, `modules/`, `flows/`, `concepts/`, and `guides/` sections plus `wiki/OVERVIEW.md`, or when asked to generate or refresh a wiki of this codebase. Includes per-folder rules and freshness and log discipline, summarizes audience/depth settings and source-reference conventions, and bundles the full generation/refresh procedure in `references/`. Complements the platform `open-knowledge` skill; does not replace it.
Kuikly asset file management and loading guide. Explains how to add, package, and load assets in Kuikly, including directory structure conventions (common/page assets), packaging configuration for each platform (Android/iOS/HarmonyOS/H5/WeChat mini programs/dynamic delivery), and use of the ImageUri API. Use when the user needs to use local image assets in Kuikly or configure assets packaging.
Build Filament admin panels on the v5 API surface THIS project targets, not deprecated v3 patterns — a reference carrying the current namespaces and conventions for Resources, forms, tables, actions, filters, relation managers, widgets, infolists, panels, and testing, with business logic kept in application Actions, so a change lands idiomatic and review-ready instead of tripping over renamed APIs. Use when a task touches this project's Filament admin panels and should target the v5 surface rather than deprecated patterns.
Generates a self-contained HTML file with an interactive, clickable Mermaid diagram (flowchart or ER diagram) explaining how a codebase feature, flow, architecture, or database schema works. Designed for fast onboarding — each walkthrough is a visual mental model readable in under 2 minutes. TRIGGER this skill when ANY of these match: - The prompt starts with or contains "$walkthrough" (explicit trigger — always activate, even if no topic follows) - The user asks to "walk me through", "walkthrough", "trace the code path", "explain this flow", "show how X works", "how does X work step by step", "explain the architecture", "visualize the data model", "show the data structures", "show the relationships" - The user wants a visual/interactive explanation of code, flows, pipelines, or schemas. When triggered, ALWAYS generate a walkthrough HTML file — never respond with just text. If "$walkthrough" is used with no topic, generate an overview walkthrough of the entire project
Identify stale feature flags in a PostHog project and clean up the code that checks them. Use when the user wants to find, audit, or remove unused, fully rolled out, or abandoned feature flags, run a feature flag hygiene review or a weekly cleanup, reduce feature flag tech debt, or asks "which flags can I remove?". When the agent can read and edit a repository it performs the code cleanup itself: tested local changes, and one draft PR per flag when the user authorizes publishing. Agents without repository access generate a tailored cleanup prompt instead. Covers staleness detection, dependency checking, retained-path rules, and the code-first ordering. This skill does not archive or otherwise change a flag in PostHog.
Comprehensive debugging methodology for finding and fixing bugs (formerly debugging). This skill should be used when debugging code, investigating errors, troubleshooting issues, performing root cause analysis, or responding to incidents. Covers systematic reproduction, hypothesis-driven investigation, and root cause analysis techniques. Use when encountering exceptions, stack traces, crashes, segfaults, undefined behavior, or when bug reports need investigation.
A Kuikly custom View development assistant. Guides you through creating custom UI components and exposing native Views for use on the Kuikly side. Covers the full development process: defining components on the Kuikly side, implementing them natively on each platform (Android/iOS/HarmonyOS ArkTS/H5/mini programs), and using them. Use when developing custom extended UI components.
Discover and use SurrealDB's built-in SurrealQL functions with accurate, version-current signatures by running the SurrealQL language server (LSP) and tree-sitter grammar, with a namespace catalog linking every function group to its docs. Use when looking up which built-in function to use, its exact signature/arguments, getting editor completions/hover/signature-help for .surql files, or confirming a function exists in the installed SurrealDB version. Triggers: SurrealQL function, built-in function, function signature, string::, array::, math::, type::, LSP, language server, completions, surrealql-language-server.
Implement or review a Remotion 5 breaking change while the v4 and v5 release lines still share code. Use when v4 behavior and public types must remain compatible on main, but flipping the central v5 flag should activate a new runtime behavior, default, or TypeScript API.
This skill should be used when the user asks to "learn from Kaggle", "study Kaggle solutions", "analyze Kaggle competitions", or mentions Kaggle competition URLs. Provides access to extracted knowledge from winning Kaggle solutions across NLP, CV, time series, tabular, and multimodal domains.
A complete development assistant for combining Compose DSL and Kuikly DSL. Provides guidance on embedding Kuikly DSL components (DeclarativeBaseView / ViewContainer) in Compose DSL pages and calling Kuikly Module from Compose. Use it when users need to reuse Kuikly DSL components in Compose pages, wrap native Views as Composables, or call Kuikly Module from Compose.
Kuikly multi-module project configuration assistant. Guides you through creating Kuikly submodules and configuring multiple modules. Use when creating a new Kuikly submodule, configuring multi-module parameters, or resolving KuiklyCoreEntry entry class conflicts.
Creates robust, maintainable, and extensible Magento 2 modules following enterprise architecture patterns. Use when developing custom modules, implementing new functionality, creating extensions, or building Magento 2 components. Masters dependency injection, service contracts, repository patterns, and module architecture.
New to MCP?
From what the protocol is to installing your first server, these answers cover most first questions.
An open protocol that defines how AI applications connect to external tools and data in a uniform way. Clients talk to the model; MCP servers provide tools, resources and prompt templates. They exchange standard messages, so one server can be reused by many clients.
