AiGo123 — AI Coding Agent for JetBrains IDEs

AiGo123 brings a full AI agent development team into your JetBrains IDE. It runs a real VS Code Extension Host inside IntelliJ IDEA, WebStorm, PyCharm, GoLand, CLion, PhpStorm, RubyMine, DataGrip, Rider and Android Studio, so the same agent you know from VS Code works natively in your JetBrains workflow.

AiGo123 is part of an ecosystem: the AiGo123.net model gateway, the KKSwitch local routing desktop app, and the AiGo123 agent itself. Use them together or independently.

What the plugin itself does

• Real Extension Host runtime: launches a bundled VS Code Extension Host process and speaks the VS Code IPC/RPC protocol, so VS Code-based agents run as first-class citizens.
• Automatic Node.js setup: downloads and installs a portable Node.js runtime (v20.19.2) into ~/.run-vs-agent/nodejs on first use — no manual Node.js installation required.
• Native IDE integration: editor, document, diff, bulk-edit, tab-state, terminal and shell-integration sync between the IDE and the agent.
• Tool Window UI: a dedicated AiGo123 tool window with theme-aware styling, drag & drop, and automatic reveal after indexing.
• Dynamic actions: toolbar buttons and editor context-menu entries (Explain Code, Fix Code, Fix Logic, Improve Code, Add to Context, New Task) that adapt to the active agent.
• Multiple agent providers: switch between AiGo123 / Roo Code, Cline, Kilo Code and Costrict.
• Resilient VSIX delivery: multi-source, multi-threaded (5 parallel ranges) download with resume, ETag/Last-Modified validation and automatic failover.
• JCEF compatibility & fallback: detects missing JCEF (including the IntelliJ 262 / 2026.2 split into com.intellij.modules.jcef) and shows a diagnostic panel instead of failing to load.

What the agent can do

• Generate code from natural-language descriptions and specs
• Refactor, debug and explain existing code
• Write and update documentation
• Answer questions about your codebase with codebase indexing
• Automate repetitive tasks and run terminal commands
• Use MCP servers, Skills, Slash Commands and custom Modes (Code, Architect, Ask, Debug)
• Follow project rules such as AGENTS.md

KKSwitch — local all-in-one API token routing (recommended)

KKSwitch is a local, all-in-one API token aggregation, routing and AI Agent integration desktop app. It manages upstream providers, models and local Agent tools in one place, with model conversion, zero-config setup, isolated multi-window workspaces, IDE integration and LAN proxy forwarding.

• Zero configuration: start mainstream AI Agent tools without editing JSON or config files.
• Protocol conversion: heuristically detect and convert between OpenAI Chat, OpenAI Responses and Anthropic Messages.
• Unified model catalog: aggregate, deduplicate and sort models from enabled providers; switching takes effect immediately without restarting your tools.
• Isolated runtime: run multiple Codex, Claude and other clients side by side across different workspaces.
• Safe by design: redacted diffs, backups, atomic writes and post-write verification; API keys stay local and are never uploaded.
• Local proxy: listens on 127.0.0.1 by default (ports 26001–26100) and exposes an OpenAI-compatible /v1 endpoint; LAN mode is opt-in.

When KKSwitch is running, AiGo123 detects it automatically and can route requests through it. Download it at www.kkswitch.com (Windows and macOS). KKSwitch is not bundled with the plugin and is not required.

AiGo123.net — model & API gateway

AiGo123.net is a next-generation large-model gateway and AI asset management platform. It provides API tokens and access to models such as Claude, Codex, DeepSeek, Gemini, Kimi, Qwen and GLM, with multi-protocol support (OpenAI Chat/Responses, Claude Messages, Google Gemini), smart routing with weighted channels and automatic retry, format conversion, and usage dashboards. It is compatible with Claude Code and other CLI tools. The plugin works with any OpenAI-compatible endpoint you configure; AiGo123.net is the recommended, ready-to-use option.

Supported IDEs

• IntelliJ IDEA (Ultimate & Community)
• WebStorm — JavaScript and TypeScript
• PyCharm (Professional & Community) — Python
• PhpStorm — PHP
• RubyMine — Ruby
• CLion — C/C++
• GoLand — Go
• DataGrip — Databases

Requirements & compatibility

• JetBrains IDE 2022.3 (build 223) or later; declared compatible up to 271.*.
• Node.js is prepared automatically (portable v20.19.2); the Extension Host requires Node.js 20.6.0+.
• JCEF is required for the embedded UI. On IntelliJ Platform 262 (2026.2)+ it is provided by the bundled Web Browser (JCEF) plugin; if it is missing, the plugin shows a diagnostic panel with recovery hints.
• Linux ARM is currently not supported by the runtime installer and is reported as unsupported in the UI.

简体中文

AiGo123 将完整的 AI 代理开发团队带入你的 JetBrains IDE。它在 IntelliJ IDEA、WebStorm、PyCharm、GoLand、CLion、PhpStorm、RubyMine、DataGrip、Rider 和 Android Studio 中运行真正的 VS Code 扩展宿主，让 VS Code 生态中的 AI 代理在 JetBrains 工作流中原生可用。

AiGo123 属于一个完整生态：AiGo123.net 模型网关、KKSwitch 本机路由桌面应用，以及 AiGo123 代理本身。可组合使用，也可独立使用。

插件本身的能力

• 真实扩展宿主运行时：启动内置的 VS Code 扩展宿主进程，使用 VS Code IPC/RPC 协议通信。
• 自动准备 Node.js：首次使用时自动下载便携版 Node.js（v20.19.2）到 ~/.run-vs-agent/nodejs，无需手动安装。
• IDE 原生集成：编辑器、文档、Diff、批量编辑、标签状态、终端与 Shell Integration 双向同步。
• 工具窗口界面：独立的 AiGo123 工具窗口，支持主题自适应、拖放，并在索引完成后自动展开。
• 动态操作：工具栏按钮与编辑器右键菜单（解释代码、修复代码、修复逻辑、改进代码、加入上下文、新建任务）随当前代理动态变化。
• 多代理提供商：可在 AiGo123 / Roo Code、Cline、Kilo Code、Costrict 之间切换。
• 可靠的 VSIX 分发：多源、多线程（5 路并发分片）下载，支持断点续传、ETag/Last-Modified 校验与自动故障转移。
• JCEF 兼容与降级：可检测 JCEF 缺失（包括 IntelliJ 262 / 2026.2 拆分为 com.intellij.modules.jcef），并显示诊断面板而非加载失败。

代理能做什么

• 根据自然语言描述与规格生成代码
• 重构、调试并解释现有代码
• 编写与更新文档
• 基于代码库索引回答代码相关问题
• 自动化重复任务并执行终端命令
• 使用 MCP 服务器、Skills、斜杠命令与自定义模式（Code、Architect、Ask、Debug）
• 遵循 AGENTS.md 等项目规则

KKSwitch —— 本机一体化 API Token 路由（推荐）

KKSwitch 是一款本机一体化 API Token 聚合、路由与 AI Agent 集成桌面应用。它把上游渠道、模型与本地 Agent 工具集中管理，提供模型转换、零配置接入、多窗口隔离工作区、IDE 集成与局域网代理转发。

• 零配置：无需编辑 JSON 或配置文件即可启动主流 AI Agent 工具。
• 协议转换：在 OpenAI Chat、OpenAI Responses 与 Anthropic Messages 之间启发式检测与转换。
• 统一模型目录：聚合、去重并排序已启用渠道的模型；切换实时生效，无需重启工具。
• 隔离运行时：在不同工作区中并行运行多个 Codex、Claude 等客户端。
• 安全设计：脱敏 diff、备份、原子写入与写后验证；API Key 仅保存在本地，绝不上传。
• 本机代理：默认仅监听 127.0.0.1（端口 26001–26100），提供 OpenAI 兼容的 /v1 接口；局域网模式需显式开启。

当 KKSwitch 运行时，AiGo123 会自动检测并可经其转发请求。可在 www.kkswitch.com 下载（支持 Windows 与 macOS）。KKSwitch 不随插件捆绑，也非必需。
