CLAUDE.md

ccNexus CLAUDE.md is an instructions file for Claude Code from lich0821/ccNexus. It costs 1,523 tokens per session, scanned A, original, MIT.

A project instruction file for ccNexus, an API proxy that rotates endpoints, converts between model API formats, manages Codex tokens, and reports usage. It also documents its desktop and server modes and common Go, Docker, and test commands.

In plain words
What is it for?
Use it when developing, testing, formatting, building, or running ccNexus and its desktop application, HTTP server, or Docker setup.
Why use it?
It gives an agent the project context and operating instructions needed to work consistently in the repository.

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Security

Grade A, and why

ccNexus CLAUDE.md scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 1mo ago.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

项目概述

ccNexus 是一个智能 API 端点轮换代理,专为 Claude Code 和 Codex CLI 设计。

核心功能:

  • 多端点轮换与自动故障转移
  • API 格式转换(Claude ↔ OpenAI ↔ Gemini)
  • Codex Token Pool 管理(自动轮换、刷新、失效隔离)
  • 实时统计与监控
  • WebDAV 云同步

两种运行模式:

  • 桌面模式:基于 Wails v2 的跨平台 GUI 应用(cmd/desktop/)
  • 服务器模式:无头 HTTP API 代理(cmd/server/)

常用开发命令

开发与构建

# 桌面应用开发模式(支持热重载)
cd cmd/desktop && wails dev

# 构建桌面应用(指定平台)
wails build -platform linux/amd64    # Linux
wails build -platform darwin/amd64   # macOS
wails build -platform windows/amd64  # Windows

# 构建服务器
cd cmd/server && go build -ldflags="-s -w" -o ccnexus-server .

# 运行服务器
cd cmd/server && go run main.go

测试

# 运行所有测试
go test ./... -count=1

# 运行特定目录的测试
cd internal/proxy && go test -v ./...
cd internal/transformer/convert && go test -v ./...

Docker

# 构建镜像
docker build -f cmd/server/Dockerfile -t ccnexus .

# 使用 docker-compose
cd cmd/server && docker-compose up -d

代码质量

go fmt ./...    # 格式化代码
go vet ./...    # 静态分析
go mod tidy     # 清理依赖

关键组件

代理层 (internal/proxy/proxy.go)

  • 管理多个 API 端点,自动故障转移
  • 跟踪当前端点和活动请求
  • 使用连接池优化的 HTTP 客户端
  • 处理流式和非流式响应

转换器 (internal/transformer/)

  • 在不同 API 格式之间转换请求和响应
  • 支持流式传输的增量转换
  • 处理工具调用和函数调用
  • 类型定义:internal/transformer/types.go

存储层 (internal/storage/sqlite.go)

  • SQLite WAL 模式数据库
  • 管理端点、凭证、使用统计、应用配置
  • 线程安全操作

关键文件路径

  • 数据库:~/.ccNexus/ccnexus.db
  • 配置常量:internal/config/config.go(第 13-20 行:认证模式和端点 URL)
  • 代理路由:internal/proxy/proxy.go(第 108-114 行)

What this file has done since we first saw it

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.
