ModelSell CLI: A Unified Entry for One-Click Configuration of Multi-Platform AI Programming Tools

ModelSell CLI is a local command-line configuration tool designed to solve the configuration fragmentation problem faced by developers when using multiple AI programming assistants. It supports mainstream tools such as Codex, Claude Code, Gemini CLI, and OpenClaw, and automatically writes configurations for API keys, API addresses, and default models through a unified interactive or non-interactive interface. As an entry tool for the ModelSell ecosystem, it acts as a configuration hub, integrating scattered configuration processes and improving development efficiency.

With the popularization of AI programming tools, developers face the dilemma of configuration fragmentation: each tool (such as Codex, Claude Code, etc.) has an independent configuration system, authentication mechanism, and model settings. Developers need to switch between different configuration files, remember multiple sets of environment variable rules, and manually modify configurations in multiple places, which is not only time-consuming but also prone to errors (e.g., API key spelling errors leading to workflow interruptions).

ModelSell CLI is the configuration gateway of the ModelSell platform ecosystem. It is written in Go language and compiled into a single executable file (no dependencies, cross-platform support). Its core functions include:

1. Interactive configuration: Guides users through steps to lower the entry barrier;
2. Non-interactive configuration: Supports command-line parameters, suitable for automation scenarios;
3. Unified configuration for multiple tools: Can configure supported tools individually or in batches;
4. Secure backup: Automatically creates timestamped backup files before writing configurations for easy rollback.

ModelSell CLI can understand and modify the configuration formats of various target tools:

• Codex: Uses TOML format ~/.codex/config.toml and JSON format ~/.codex/auth.json;
• Claude Code: JSON format ~/.claude/settings.json;
• Gemini CLI: JSON format ~/.gemini/settings.json and .env file;
• OpenClaw: JSON format ~/.openclaw/openclaw.json and .env file. This differentiated handling adapts to the design conventions of each tool.

There are various installation methods:

1. Installation script (recommended for macOS/Linux):
   • Main address: curl -fsSL https://raw.githubusercontent.com/modelsell/modelsell-cli/main/install.sh | sh
   • Alternative address: curl -fsSL https://static.modelsell.com/modelsell-cli/install.sh | sh By default, it is installed to ~/.local/bin/modelsell (following XDG specifications);
2. Precompiled binaries: GitHub Releases provides precompiled files for mainstream platforms (macOS Apple Silicon/Intel, Linux ARM64/x64, Windows x64).

Main application scenarios:

1. Team environment standardization: Integrate into initialization scripts to allow new members to quickly obtain consistent configurations;
2. Multi-account switching: Quickly switch via the MODELSELL_API_KEY environment variable combined with shell configuration;
3. CI/CD integration: Non-interactive mode seamlessly integrates into pipelines such as GitHub Actions and GitLab CI to automatically configure the environment.

Current limitations: Focuses only on configuration management, not involving model call proxy or caching; relies on the ModelSell platform as an intermediate layer (requires trust in its stability and security). Future outlook: May expand more functions, but currently focuses on simplifying the configuration process.

The value of ModelSell CLI lies not only in simplifying configuration steps but also in transforming manual configuration into version-controllable, automated, and auditable code-based operations, extending the concept of 'configuration as code'. It centers on developer experience, building an efficient ecosystem entry by eliminating friction, respecting habits, and providing choices.
