Token-efficient codebase exploration using MCP servers (Serena, Context7, JetBrains, Claude-mem). Reduces token usage by 80-90% through structured queries. Use ALWAYS before reading files to minimize context window usage.

Evaluate TYPO3 extensions for conformance to official TYPO3 12/13 LTS standards, coding guidelines (PSR-12, TYPO3 CGL), and architecture patterns. Use when assessing extension quality, generating conformance reports, identifying technical debt, or planning modernization efforts. Evaluates: extension architecture, composer.json validation (mandatory fields, version constraints, deprecated properties), ext_emconf.php validation (state values, categories, constraints, critical TER restrictions), comprehensive ext_* files validation (ext_localconf.php, ext_tables.php, ext_tables.sql, ext_tables_static+adt.sql, ext_conf_template.txt), TYPO3 v13 deprecation detection (deprecated TypoScript files, addUserTSConfig, backend module migration, Site sets adoption), dependency injection, services configuration, testing coverage, Extbase patterns, best practices alignment, Crowdin integration, and GitHub workflow validation (issue templates, TER publishing automation). Supports PHP 8.1-8.4 and provides actionable improveme

后端开发专家，负责 Express.js + Knex.js + MySQL 8 + Redis 后端服务开发。遵循 OpenAPI 先行、TDD 推动、RBAC 安全、可观测性工程基线。处理 Provider 动态加载、缓存系统、数据库设计、内容管理 API 开发。适用于收到 Backend 部门任务卡（如 CMS-B-001）或修复类任务卡时使用。

This skill must be used with any prompt that uses MXCP. MXCP is an enterprise-grade MCP (Model Context Protocol) framework for building production AI applications with SQL and Python endpoints, security, audit trails, policy enforcement, and comprehensive testing. Use this skill when working with MXCP in any capacity including creating, building, initializing, setting up, or editing MXCP servers or projects, configuring MCP tools/resources/prompts, implementing endpoints, setting up authentication/policies, debugging validation errors, or troubleshooting MXCP applications.

Initialize Rails coding conventions for a project by detecting dependencies and copying matching rules with examples to .claude/rules/hustler-rails/. Use when setting up Rails conventions for a new project or updating existing rules. Trigger with phrases like "initialize rails rules", "setup rails conventions", "init hustler-rails".

Unvarnished technical criticism combining Linus Torvalds' precision, Gordon Ramsay's standards, and James Bach's BS-detection. Use when code/tests need harsh reality checks, certification schemes smell fishy, or technical decisions lack rigor. No sugar-coating, just surgical truth about what's broken and why.

Enforce governance, approvals, and safety boundaries for autonomous actions; use when asked to define or apply guardrails.

Map change impact radius by tracing what breaks when modifying functions, types, or APIs to quantify migration effort before proposing changes. Use when: (1) proposing to change function signatures, rename exports, or modify public APIs before checking what calls them, (2) a change is characterized as safe without verifying how many callers exist and where they are, (3) shared types or components are about to be modified without analyzing type propagation to distant code, (4) a proposed change lacks a list of specific files and locations that would be affected.

Build production-grade MCP (Model Context Protocol) servers with observability, correlation ID tracing, and dual logging. Use when creating new MCP servers, adding tools to existing servers, implementing file logging, debugging MCP issues, wrapping CLI tools with spawnSyncCollect, or following Side Quest marketplace patterns. Covers @sidequest/core/mcp declarative API, @sidequest/core/spawn CLI wrapper patterns, Zod schemas, Bun runtime, and 9 gold standard patterns validated across Kit plugin (18 tools). Includes error handling, response format switching, MCP annotations, and graceful degradation.

This skill should be used to fix visual hierarchy when everything looks equally important, CTAs don't stand out, or users miss key information. Applies Von Restorff Effect, Serial Position Effect, and Law of Prägnanz.

Production deployment patterns for the World of Darkness Django application. Use when deploying to staging/production, configuring security settings, setting up Redis cache, planning database migrations, or preparing rollback procedures. Triggers on deployment tasks, production configuration, security hardening, or environment-specific settings.

Respond to incidents and apply remediations - restart services, scale resources, clear caches, update configurations, rollback deployments, apply fixes, verify remediation success, document actions taken, track remediation history.

Component skill for systematic result interpretation with intellectual honesty in DataPeeker analysis sessions

Systematic debugging process for Laravel applications - ensures root cause investigation before attempting fixes. Use for any Laravel issue (test failures, bugs, unexpected behavior, performance problems).

Master Express.js API development with middleware, routing, validation, authentication, and production best practices. Build scalable RESTful APIs with Express.

Use when creating or developing Laravel features, before writing code or implementation plans - refines rough ideas into fully-formed Laravel designs through collaborative questioning, alternative exploration, and incremental validation.

Research GitHub, GitLab, and Bitbucket repositories using DeepWiki MCP server. Use when exploring unfamiliar codebases, understanding project architecture, or asking questions about how a specific open-source project works. Provides AI-powered repo analysis and RAG-based Q&A about source code. NOT for fetching library API docs (use fetching-library-docs instead) or local files.

Provides Next.js project architecture expertise and implementation patterns. Enforces BFF (Backend for Frontend) pattern, Server Components strategy, and data fetching policies. Specializes in App Router architecture, Server Actions, streaming SSR, incremental static regeneration, and route handlers. Ensures optimal performance through proper component boundaries and caching strategies. Use when: developing Next.js applications, implementing App Router patterns, creating Server Components and Client Components, designing Server Actions for mutations, implementing data fetching with fetch API, configuring BFF architecture, optimizing page performance with streaming and suspense, handling routing and navigation, implementing middleware, or setting up API route handlers.

Execute compliance audit workflows with evidence trails and approvals; use when asked to verify SOC2, HIPAA, or GDPR controls.

Test Node.js applications with Jest including unit tests, integration tests, mocking, code coverage, and CI/CD integration
