SYSTEM DOCUMENTATION & REQUIREMENTS

What problem does it solve?

This Skill provides a secure method for agents to set API keys, secrets, or other sensitive credentials within a project's .env file, preventing them from being exposed in terminal output or conversation history.

Core Features & Use Cases

Secure Credential Management: Uses a companion CLI (controller-cli) to interact with The Controller app for secret input.
Masked Input: The secret value is entered via a masked modal in the UI, ensuring it's never visible in the terminal.
Use Case: An agent needs to configure an OpenAI API key for a new project. It uses this Skill to prompt the user for the key securely and writes it to the project's .env file without logging the key itself.

Quick Start

Use the controller-cli to set the OPENAI_API_KEY for the 'my-app' project.

FAQPage Schema

How do I securely set API keys in an env file without exposing secrets in terminal output?▼

To securely set API keys in an env file without exposing secrets, use a CLI tool that interfaces with a desktop application to capture input via a masked UI modal and write directly to the file. This prevents sensitive credentials from appearing in terminal logs or chat history.

Can I configure credentials for a development environment using a masked input modal?▼

Yes, you can configure credentials for a development environment using a masked input modal. A companion CLI tool triggers the desktop application UI to securely capture the secret value, ensuring the input is never visible and writing it directly to the target project's environment file.

How does a CLI tool write secrets to a .env file without logging the values?▼

A CLI tool writes secrets to a .env file without logging values by interfacing with a desktop application to open a masked UI modal for input, bypassing the terminal entirely. The secret is then written directly to the target project's environment file.

Do I need a desktop application running to securely input API keys via the controller-cli?▼

Yes, you need the desktop application running to securely input API keys via the controller-cli. The CLI tool acts as an interface that triggers the desktop app's masked modal to capture secrets and write them to the project's environment file safely.

What is the best way to manage secrets for an agent configuring a project?▼

The best way to manage secrets for an agent configuring a project is using a dedicated CLI to interact with a desktop application. This approach securely captures credentials through a masked UI modal and writes them directly to the .env file, preventing exposure in conversation history.

Are there limitations when using a masked UI modal to set environment variables?▼

A limitation of using a masked UI modal to set environment variables is the dependency on a desktop application and its companion CLI. This approach requires a graphical interface for input, making it unsuitable for headless server environments or automated background scripts without direct user interaction.
