Advanced yargs patterns for Node.js CLI argument parsing with subcommands, options, middleware, and validation

First-principles deep thinking for significant problems

Knowledge and patterns for understanding project structures, architectures, and codebases.

開発における基本原則（曖昧さ禁止、矛盾検出、推察禁止）を定義する。要件定義時、仕様確認時、設計レビュー時、またはユーザーが曖昧な要件、仕様の矛盾、不明点の確認、推測回避に言及した際に使用する。

Explore and query blockchain subgraphs through a private MCP server running in Docker. Use this skill when exploring GraphQL subgraphs, querying blockchain data from subgraphs (NFT transfers, DEX swaps, DeFi metrics), examining subgraph schemas, or exporting discovered queries for project use. The skill manages Docker-based MCP server interaction and provides utilities for query development and export.

Modern type-safe Typer CLI patterns with type hints, Enums, and sub-apps. Use when building CLI applications, creating Typer commands, implementing type-safe CLIs, or when user mentions Typer, CLI patterns, type hints, Enums, sub-apps, or command-line interfaces.

Activate when user mentions "codex review", "code review", "fix pr code review". This skill provides guidance on how to effectively collaborate with codex to do a interate code review.

Create production-ready FastAPI projects with async patterns, dependency injection, and comprehensive error handling. Use when building new FastAPI applications or setting up backend API projects.

Configure Static Application Security Testing (SAST) tools for automated vulnerability detection in application code. Use when setting up security scanning, implementing DevSecOps practices, or automating code vulnerability detection.

Use when releasing, tagging, or bumping versions. Defines semver rules and keeps package.json/pyproject.toml synced with git tags.

Interactive prompt patterns for CLI tools with text, list, checkbox, password, autocomplete, and conditional questions. Use when building CLIs with user input, creating interactive prompts, implementing questionnaires, or when user mentions inquirer, prompts, interactive input, CLI questions, user prompts.

Execute database migrations across ORMs and platforms with zero-downtime strategies, data transformation, and rollback procedures. Use when migrating databases, changing schemas, performing data transformations, or implementing zero-downtime deployment strategies.

Create video compositions with @editframe/react React wrappers. Use when working with React components like Timegroup, Video, Audio, Image, Text, Captions, Waveform, Surface, Configuration, Preview, Controls, or building React-based video compositions with TypeScript.

Use when integrating crates or ecosystem questions. Keywords: E0425, E0433, E0603, crate, cargo, dependency, feature flag, workspace, which crate to use, using external C libraries, creating Python extensions, PyO3, wasm, WebAssembly, bindgen, cbindgen, napi-rs, cannot find, private, crate recommendation, best crate for, Cargo.toml, features, crate 推荐, 依赖管理, 特性标志, 工作空间, Python 绑定

Coffee break companion. Get brewing recipes, timing guides, and unsolicited opinions about coffee. Yes, I know you own the company.

This skill should be used when the user asks to "query Langfuse traces", "show sessions", "check LLM costs", "analyse token usage", "view observations", "get scores", "create score", "add score to trace", "query metrics", or mentions Langfuse, traces, or LLM observability. Also triggers on requests to analyse API latency, debug LLM calls, or investigate model performance. Use for prompt management tasks like "list prompts", "get prompt", "create prompt", "update prompt labels", or "deploy prompt to production". Use for dataset management tasks like "list datasets", "create dataset", "add dataset item", "view dataset runs", or "manage evaluation datasets".

Migrate from AngularJS to Angular using hybrid mode, incremental component rewriting, and dependency injection updates. Use when upgrading AngularJS applications, planning framework migrations, or modernizing legacy Angular code.

Design multi-stage CI/CD pipelines with approval gates, security checks, and deployment orchestration. Use when architecting deployment workflows, setting up continuous delivery, or implementing GitOps practices.
