Secure API Key Management with EnvSkill for AI Agents

Secure API Key Management with EnvSkill for AI Agents

EnvSkill provides secure API key management for AI coding agents such as Claude Code, Cursor, and Codex. This skill safeguards environment secrets by injecting only named variables into commands without exposing their values, ensuring confidentiality within your development ecosystem.

What this skill does

• Acts as a boundary between secret values and commands that require them.
• Guides first-time setup to initialize an owner-only store, detect supported agent hosts, install the skill, and verify installations without revealing secret values.
• Allows the import of existing dotenv files without displaying values using the command: envskill setup --agent all --import ~/.env.
• Keeps existing secret names by default, with options to overwrite if explicitly requested.
• Discovers available environment variable names using envskill list.
• Checks the presence of required variable names with envskill has NAME.
• Executes target commands with restricted credential scopes via envskill run --only NAME1,NAME2 -- command args....
• Prompts the user to set missing environment variables securely, without echoing values.

Who it is for

EnvSkill is designed for developers and development teams utilizing AI coding agents in their workflows. It is particularly useful for those focused on maintaining the confidentiality of API keys and environment secrets.

Use cases

• Injecting API keys for cloud services during automated code execution with AI agents.
• Maintaining secure access to sensitive data within CI/CD pipelines using Claude Code, Cursor, or Codex.
• Managing development environments on shared systems without exposing secrets.

Technical details

• Utilizes the envskill command-line interface for secure value handling.
• Compatible with supported agent hosts including Claude Code, Cursor, and Codex.
• Ensures that secret values are not revealed via environment variable listings, shell expansions, or logs.
