What problem does it solve? Skills that call external APIs often fail silently or leak secrets when credentials are missing or mishandled. This Skill defines a safe protocol for checking whether required API keys exist in a .env file and prompting the user to add them without ever exposing secret values in the chat or terminal output. ## Core Features & Use Cases - Leak-Free Verification: Uses grep in quiet mode (grep -sq) to confirm a credential exists in ~/.env without printing or reading its value into context. - Secure Prompting Templates: Generates a terminal command using read -s so the user can type the credential with hidden input, appending it to the .env file and creating the file if needed. - Automatic Loading: Explains that helper scripts load credentials via dotenv, so no manual exporting or CLI argument passing is required. - Use Case: When a skill requires ALPHAGENOME_API_KEY, the agent first runs grep -sq "^ALPHAGENOME_API_KEY=" ~/.env; if it fails, it immediately gives the user a hidden-input command plus the registration link instead of attempting the API call. ## Quick Start Check whether the required API key is present in my .env file and, if it is missing, give me a safe terminal command to add it without revealing the value.
