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 the agent's capabilities with specialized knowledge, workflows, or tool integrations.
Create new skills, modify and improve existing skills, and measure skill performance. Use when users want to create a skill from scratch, update or optimize an existing skill, run evals to test a skill, benchmark skill performance with variance analysis, or optimize a skill's description for better triggering accuracy.
Install Codex skills into $CODEXHOME/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).
Quick reference for code-review-graph (CRG) MCP tools. Use when you need to look up a CRG tool name, parameter, or pattern. For workflow guidance, see AGENTS.md decision checkpoints. Requires aios internal codemap install.
AIOS-native long-running agent harness with rex Command execution, ContextDB, checkpoint recovery, and evidence capture. Use for a planned resumable objective when AIOS is installed. If AIOS is NOT installed, use harness-init-runner for a lightweight standalone alternative.
Use when operating in the aios repository and needing the canonical architecture, memory schema, MCP browser tool behavior, and execution constraints before changing workflows.
Decide when a coding agent may use aios work for independent parallel work, preview the dispatch, and require explicit approval before live model execution. TRIGGER: aios work、parallel dispatch、并发派发、independent work items、独立工作项并行、多 agent 派发、multi-agent dispatch.
Route AIOS host dispositions and execute the current rex-harness software Capability Command. TRIGGER: 分析、设计、实现、调试、并发、agent team、长任务、harness、plan、工作流、多步骤.
Create a DESIGN.md style baseline BEFORE building UI. Use FIRST when no design draft exists — installs a proven visual style, then invoke frontend-design to implement. For borrowing a known product style, getting consistent typography/colors/spacing, or needing a fast visual starting point.
Automatic ContextDB session lifecycle — init, session events, checkpoints, and continuity artifacts. Use when you need AIOS context persistence without prompt injection. NOT for general task execution — only for ContextDB session management. TRIGGER: contextdb、session persist、checkpoint save.
Evidence-first debugging WITH MCP tools. Use when debughub MCP server is available. Inject log calls, collect via HTTP API (port 39200), analyze through MCP tools, clean up when done. If debughub MCP is unavailable, use debug skill (bundled Python collector) instead.
Helps users discover and install agent skills when they ask questions like "how do I do X", "find a skill for X", "is there a skill that can...", or express interest in extending capabilities. This skill should be used when the user is looking for functionality that might exist as an installable skill.
Build production-grade frontend UI with distinctive design. Use AFTER establishing design direction — if no DESIGN.md exists, invoke awesome-design-md first to create one, then use this skill to implement. For web components, pages, landing pages, dashboards, React components, HTML/CSS layouts, or styling any web UI.
Initialize a lightweight repo-local Node.js harness (harness/ + .harness/) WITHOUT AIOS dependency. Use ONLY when you need a standalone, portable harness. If AIOS is installed, use aios-long-running-harness instead — it has rex Command hosting, ContextDB integration, and checkpoint recovery.
A model-selection workflow that assigns different coding tasks to different AI models based on their abilities, cost, and the task’s risk or complexity.
Prepare a safe, current, and maintainable code change before editing. Use before a cohesive code or workflow change to assess the request and existing structure, then choose a local change, reuse, extension, or necessary refactor with clear ownership. Do not use to block ordinary TDD or authorized refactors.
Use when the user wants to generate an image, edit an image, create visual artwork, produce text-to-image output, transform an existing image with image-to-image, or asks for 生图, 生成图片, 文生图, 图生图, text-to-image, image-to-image, AI image, picture generation, image result, image edit, or visual generation.
Research-before-building workflow. Use when adding new behavior, dependencies, or integrations to avoid reinventing and to stay compatible across codex/claude/gemini/opencode.
Use when improving a single page for SEO and AI answer-engine visibility (GEO), especially when you need faster first-screen conversion and clearer traffic funnels.
Enforce browser automation safety constraints — tool usage order, anti-detection rules, screenshot discipline, and human-in-the-loop checks. Use when setting up or verifying browser/MCP tool operations, NOT for every skill execution.
