Supports both personal skills and standalone distributable skills (GitHub repos). (user)
Use when Codex is building or iterating on a web game (HTML/JS) and needs a reliable development + testing loop: implement small changes, run a Playwright-based test script with short input bursts and intentional pauses, inspect screenshots/text, and review console errors with render_game_to_text.
General principles for exploring, developing, editing, and refactoring code. Use for codebase analysis, implementation tasks, and code quality improvements.
設計と実装を「最小で正確」に進め、TDD（RED→GREEN→REFACTOR）と差分思考で品質と速度を両立する。設計の溶け込み（責務不明/重複/暫定対応）を防ぎ、レビュー可能な変更へ落とし込むときに使う。
Build, create, debug, review, implement, and optimize agentic AI applications using the OpenAI Agents SDK for TypeScript. Use when creating new agents, defining tools, implementing handoffs between agents, adding guardrails, debugging agent behavior, reviewing agent code, or orchestrating multi-agent systems with the @openai/agents package.
Guide for contributing to the OpenAPI layer using processor pattern, complexity management, and functional programming. Use when adding endpoint factories, processors, parameter descriptions, reducing cyclomatic complexity, or fixing OpenAPI validation errors. Covers architecture patterns from user-service repository.
Build OpenCode plugins, agents, hooks, and tools. Use when creating, reviewing, or debugging OpenCode extensions. Covers plugin architecture, agent configuration, lifecycle hooks, custom tools, and distribution. Invoke PROACTIVELY when user mentions OpenCode plugins, agents, hooks, or wants to extend OpenCode functionality.
dev:developing
Personal development philosophy emphasizing experiment-driven, fail-fast approach. Activate when planning implementations, reviewing code architecture, making design decisions, or when user asks to apply development principles. Guides against over-engineering and towards solving real problems with simple solutions. (project, gitignored)
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。
Modern development process patterns for shipping faster with higher quality
End-to-end agent development process. Use when coordinating work, dispatching agents, or reviewing PRs.
Use when substantive documents (reviews, analyses, synthesis documents) need adversarial review to strengthen arguments, identify weak points, and challenge assumptions before editorial polish (mandatory for Writer → Devil's Advocate pairing protocol)
DevOps patterns including CI/CD pipeline design, GitHub Actions, Infrastructure as Code, Docker, Kubernetes, deployment strategies, monitoring, and disaster recovery. Use when setting up CI/CD, deploying applications, managing infrastructure, or creating pipelines.
Use this skill when designing or reviewing CI/CD pipelines, deployment strategies, observability systems, incident response, or any system involving production operations and reliability. Applies operational thinking to specifications, designs, and implementations.
Workshop an improvement idea into implementation plan
Task tracking for async/multi-step work. Use dex to create, track, and complete tasks that span multiple sessions or require coordination (e.g., coding agent dispatches, PR reviews, background jobs). Tasks stored as JSON files in .dex/tasks/.
Check for system improvements (learnings + Claude updates)
Expert at writing and reviewing Rails code following DHH's style as practiced at 37signals. Use when writing new Rails code, reviewing Rails code, making architectural decisions in Rails apps.
<objective>
Read state.json and diagnose PR statuses, errors, stuck entries, and anomalies.
Generate publication-quality technical diagrams using Nano Banana Pro (Gemini 3 Pro Image) with AI-powered quality review. Smart iteration only regenerates when quality is below threshold.
Transform ambiguous specs into implementable work items through adversarial refinement. This skill should be used PROACTIVELY when receiving specs, claiming epics, or starting work on complex (l/xl) tasks. Use /breakdown for spec→tasks decomposition, /refine for sharpening individual items.
Review and write React/Next.js components for Diamond Fysio project. Use when reviewing components, adding features, or checking code quality. Enforces project patterns like Tailwind CSS, accessibility, Contentful integration, and i18n.
Applies the Diataxis framework to create or improve technical documentation. Use when being asked to write high quality tutorials, how-to guides, reference docs, or explanations, when reviewing documentation quality, or when deciding what type of documentation to create. Helps identify documentation types using the action/cognition and acquisition/application dimensions.
Preview and analyze git diffs with AI explanations. Use to understand changes before committing, get impact analysis, and compare branches or commits.
Generate comprehensive, reviewer-ready code review documents from git diffs. Use this when the user provides code changes (git diff output, file changes, or asks to review code changes) and wants a structured review document. Creates detailed analysis covering change overview, business flow, key code explanation, risk assessment, and review recommendations. Supports both manual diff input and automatic git workspace detection. Particularly useful for reviewing pull requests, feature branches, or any code changes requiring thorough documentation for reviewers.
Have Gemini review git changes for a second perspective on code quality.

Comprehensive Django best practices covering project structure, models (field choices, Meta options, managers, QuerySets, migrations), views (CBVs vs FBVs, generic views), Django REST Framework (serializers, ViewSets, permissions), forms, templates, security (CSRF, XSS, SQL injection), performance (N+1 queries, select_related, prefetch_related, caching), testing, and common anti-patterns. Essential reference for Django code reviews and development.
