Development

Apply Clean Architecture layering and dependency rules (Domain, Application, Infrastructure, Presentation layers). Use when structuring applications or ensuring dependencies point inward.

Perform safe code refactoring with reference checking and validation. Uses Miller's rename_symbol for workspace-wide renames and fast_refs for impact analysis. Activates when user wants to refactor, rename, or safely modify code.

Confidence-based code review that filters issues to 80+ threshold, eliminating false positives and noise. Reviews implementation against plan or requirements for bugs, quality issues, and project conventions. Use after completing major features, before merging to main, or after each task in multi-step workflows. Do NOT use for quick fixes, single-line changes, or when you need immediate feedback - the thorough review adds overhead best reserved for significant changes.

Master index of all available skills for development workflows. Use when needing guidance on which skill to apply or when starting work on any project.

プルリクエストのレビューコメントを確認し、対応用のタスクファイル作成をサポートします。githubスキルを使用してレビューコメントを取得し、Claude Codeがその情報を元にtmp/todoフォルダにタスクファイルを作成します。

Cypress end-to-end and component testing patterns for web apps: reliable selectors, stable waits, network stubbing, auth handling, CI parallelization, and flake reduction

Comprehensive protocol for validating root causes of software issues. Use when you need to systematically debug a complex bug, flaky test, or unknown system behavior by forming hypotheses and validating them with specific tasks.

Use this skill when implementing game UI addon interactions in SND macros. Covers crafting addons, shop addons, node access, and general game addon patterns.

Detects when a Claude Code session reaches a "wow moment" worth sharing with the team. A wow moment occurs during intensive back-and-forth discussions where both user and Claude deeply engage on a topic - repeatedly refining ideas, pushing back, questioning assumptions, and ultimately producing brilliant insights about effective human-AI collaboration. Triggers when the conversation shows signs of deep "cooking" - multiple sustained exchanges on the same topic, productive disagreements, or breakthrough moments emerging from persistent dialogue. This skill should stay alert throughout the session and invoke /show-ropes when a genuinely valuable agentic mindset insight emerges.

Web search and content extraction via Brave Search API. Use for searching documentation, facts, or any web content. Lightweight, no browser required.

This skill should be used when docs-researcher agent needs guidance on "how to search documentation", "WebSearch query patterns", "filtering search results", "documentation research strategy", or "creating knowledge files". Provides systematic methodology for effective technical documentation research.

Use PROACTIVELY when creating new Claude Code skills from scratch. Automated generation tool following Claudex marketplace standards with intelligent templates, pattern detection, and quality validation. Supports guided creation, quick start templates, clone-and-modify, and validation-only modes. Not for modifying existing skills or non-skill Claude Code configurations.

Standard Operating Procedure for /plan phase. Covers research depth, code reuse detection, design pattern selection, and architecture planning.

Master AI and machine learning tools including TensorFlow, PyTorch, scikit-learn, LLMs, and prompt engineering. Use when building machine learning models, working with AI agents, or implementing data science solutions.

Establish enterprise-grade code quality baselines for the .NET solution: analyzers, nullability, formatting, complexity limits, and review-ready diffs. Use when changing production code, refactoring, or introducing new project patterns.

Expert prompt engineering for Claude 4 models (Sonnet 4.5). Use when crafting prompts, optimizing AI responses, implementing chain-of-thought, or improving prompt clarity and effectiveness. Specializes in Claude-specific techniques and best practices.

Comprehensive F* proof-oriented programming for formal verification including dependent types, refinement types, effect system, SMT solver integration, tactic-based interactive theorem proving, and verified code extraction to OCaml, F#, C, WebAssembly, and Assembly

Build and run AI agents using Claude Code CLI. Use when developing autonomous agents, multi-agent systems, CI/CD automation, or scripting Claude for programmatic tasks. Covers authentication, headless mode (-p), JSON output parsing, tool restrictions, subagents, and orchestration patterns.

Use when the user asks to run Codex CLI (codex exec, codex resume) or references OpenAI Codex for code analysis, refactoring, or automated editing
