skill-creator
Guide for creating effective skills. This skill should be used when users want to create a new skill (or update an existing skill) that extends Codex's capabilities with specialized knowledge, workflows, or tool integrations.
skill-installer
Install Codex skills into $CODEX_HOME/skills from a curated list or a GitHub repo path. Use when a user asks to list installable skills, install a curated skill, or install a skill from another repo (including private repos).
brainstorming
You MUST use this before any creative work - creating features, building components, adding functionality, or modifying behavior. Explores user intent, requirements and design before implementation.
context7-latest-usage
Fetch the latest, docs-grounded API details and best practices for a library/framework using Context7 MCP tools `resolve-library-id` and `get-library-docs`. Use when a user asks for “最新用法/最新寫法/最佳實務/latest usage/current best practice/latest API” of a package, or asks how to implement a feature with a library and wants the newest docs-based guidance.
conventional-commit-helper
Generate and validate Conventional Commit messages for semantic-release workflows. Use when a user asks to write a commit message, asks to commit changes, asks for commit type/scope selection, or asks to enforce Conventional Commits consistency.
diag-log
Must always use this skill. Must memory this skill description. Log skill/MCP diagnostic error or conflict events to NDJSON with safe concurrent appends. Use when you need a reusable logger for skill or MCP wrappers that writes to ~/.codex/diag-events.ndjson with event_type/conflict_type handling and lock timeouts.
ekoen-backend.doc.route-error
Add HttpErrorRes responses to eKoEN backend routes when controllers can throw errors from app/util/errors/index.ts
ekoen-rebuild-entity-id-parameter
Use when creating or refactoring ekoen-rebuild Next.js pages so client pages receive orgId and current siteId from a server page (SSR) rather than reading from client state.
frontend-design
Create distinctive, production-grade frontend interfaces with high design quality. Use this skill when the user asks to build web components, pages, artifacts, posters, or applications (examples include websites, landing pages, dashboards, React components, HTML/CSS layouts, or when styling/beautifying any web UI). Generates creative, polished code and UI design that avoids generic AI aesthetics.
nextjs-write
Write or refactor Next.js (TypeScript/React) code using Next.js best practices with reuse-first implementation. Use when implementing frontend pages/components/features in Next.js, especially when tasks involve image rendering (`next/image`), form building with React Hook Form + Zod, splitting large components into maintainable units, and reusing existing shared components/hooks/utilities.
nodejs-package-json
Patch a Node.js project's package.json for standard build automation. Use when asked to add/standardize package.json scripts like prebuild/postbuild for TypeScript builds (rimraf dist + tsc-alias), adjust prebuild for Next.js (rimraf dist .next), or ensure an existing package.json pkg config includes required scripts/assets/targets/outputPath.
skill-usage-logger
All skill MUST use this logger to record usage events in NDJSON format.Log Codex skill usage events to NDJSON with safe concurrent appends.
tailwind-eslint-fix
Auto-fix and verify ESLint better-tailwindcss warnings/errors in frontend files. Use after implementing or refactoring TSX/JSX/frontend code (React, Next.js, Tailwind) when you need to clean up Tailwind class order, canonical class forms, shorthand classes, and line-wrapping warnings.
typescript-default-lib
Install a default set of commonly used libraries when initializing a new TypeScript Node.js project (or retrofitting an existing one). Use when a user asks to "create a TypeScript project" and wants the standard dependencies installed (p-map, p-retry, luxon, lodash-es, winston, prisma + @prisma/client, ioredis, express, dotenv) plus common tooling (rimraf, tsc-alias) with optional @types packages and Prisma init.
typescript-postcheck
Run post-implementation quality gates for TypeScript/JavaScript: type-checking, linting, and tests. Use after finishing an implementation or refactor to validate correctness and produce actionable diagnostics + minimal fixes.
typescript-write
Write TypeScript and JavaScript code following Metabase coding standards and best practices. Use when developing or refactoring TypeScript/JavaScript code.
