CI/CD

Official Anthropic SDK for Claude AI with chat, streaming, function calling, and vision capabilities

Use when errors occur deep in execution and you need to trace back to find the original trigger - systematically traces bugs backward through call stack to identify source of invalid data

A learning methodology skill based on Dr. Justin Sung's PACER system for effective information retention and application. Use when helping users (1) learn new material efficiently, (2) take notes or summarize content, (3) create study plans, (4) review or memorize information, (5) understand how to retain knowledge better, or (6) process educational content like books, lectures, courses, or articles.

Check Swift naming conventions for iOS code. Validates class names, variables, functions, and IBOutlets against project standards. Use when reviewing code readability, checking abbreviations, or enforcing naming consistency in Swift files.

Deploys applications to Cloudflare Pages including Functions, KV, D1, and R2 bindings. Use when deploying to the edge, building globally distributed applications, or using Cloudflare's ecosystem.

Diagnose and fix Flutter build failures, including dependency conflicts, Gradle errors, compilation issues, and platform-specific build problems. Use when builds fail locally or in CI.

Provides REQ-* key pattern definitions, validation rules, and traceability operations. Use for understanding requirement key formats, validating keys, or tracing requirements through the SDLC lifecycle.

Meta-skill for selecting correct WorldCrafter skill. Use when unclear which skill to use, request maps to multiple skills, need to orchestrate skills, user asks for guidance, or ambiguous requests need clarification. Provides decision trees and trigger matching for feature-builder (complete features with forms), database-setup (tables/migrations/RLS), test-generator (add tests), route-creator (simple pages/APIs), auth-guard (authentication/authorization), ai-assistant (AI generation/suggestions/consistency), visualization (maps/timelines/graphs), and chatgpt-setup (MCP integration). Do NOT use when request clearly maps to one skill or trigger phrases clearly indicate specific skill.

Create world-class, production-grade technical documentation with exceptional clarity and precision. Use this skill when the user asks to write READMEs, API references, guides, or code comments. Generates professional, accessible content that rivals top-tier tech companies.

Use when receiving code review feedback, before implementing suggestions, especially if feedback seems unclear or technically questionable - requires technical rigor and verification, not performative agreement or blind implementation

Best practices for code structure, error handling, and reducing duplication.

Build TM Forum (TMF) MCP servers from TMF OpenAPI specs (TMF6xx/7xx YAML). Use when you are given a TMF OpenAPI file and asked to (1) implement an MCP server exposing TMF operations as tools, (2) generate a mock TMF API server + client + MCP layer, or (3) standardize tool naming, create/update inputs, $ref/allOf handling, and /hub event-subscription patterns for TMF APIs.

Spawn and manage Claude sub-agents for parallel or delegated tasks. WHEN: User needs parallel operations, multi-step autonomous research, or wants to delegate complex tasks to sub-agents. Use when task can be parallelized or requires independent exploration. WHEN NOT: Simple single-step operations, sequential dependencies, specific file reads (use fs_read_file), writing code directly (do it yourself).

Analyze portfolio data from Fidelity and Tastytrade CSV files. Use when analyzing positions, performance, or risk metrics from financial data.

Docker, Kubernetes, CI/CD, model monitoring, and cloud platforms. Use for deploying ML models to production, setting up pipelines, or infrastructure.

Expert guidance for Zig build system engineering. Use when working with build.zig files, including creating new build configurations, adding executables/libraries/tests, managing dependencies and modules, setting up cross-compilation, configuring build options, troubleshooting build issues, or any other Zig build system tasks. Provides patterns, API references, and best practices for the Zig build system's DAG-based architecture.

CRA評価パイプラインのオーケストレーター。対象（Android端末FW、Androidアプリ、PCアプリ、Webアプリ）に応じた適切なスキルを連携させてCRAフル評価を自動実行。Triggers on: CRA full assessment, CRA pipeline, security assessment pipeline, automated CRA evaluation, skill orchestration, full security review, Android device, Android app, PC app, web app, CRAフル評価, CRA分析, セキュリティ評価.

Use when working on Nuxt 4+ projects - provides server routes, file-based routing, middleware patterns, Nuxt-specific composables, and configuration with latest docs. Covers h3 v1 helpers (validation, WebSocket, SSE) and nitropack v2 patterns.

Global frontend aesthetics skill that helps Claude avoid generic "AI slop" UI and make bold, intentional visual decisions while still honoring each project's design-dna, tokens, and architecture.

Work on the LaTeX thesis or LaTeXML HTML output. Use for build/lint/serve commands, LaTeX style rules, HTML pipeline notes, or assets conventions.
