AI BriefingSecurity standard aiignore for AI agents released
Key point
aiignore, an open spec that defines the scope of data an AI agent can access or modify, has been released.
Details
The public alpha version of aiignore, an open spec and reference implementation for controlling what information AI agents can explore, read, modify, execute, or transmit, has been released.
This technology works similarly to .gitignore, setting a project's security boundaries through an .aiignore.yaml file. It goes beyond existing file-level restrictions to enable the following granular controls:
- Files and directories: Block access to specific paths
- Environment variables: Drop variables with certain name patterns (e.g.,
*_SECRET) - Network: Restrict communication to allowed URLs/domains
- Strings: Redact sensitive information (e.g., Private Keys) in outputs, network requests, and logs
It currently includes a TypeScript reference implementation and CLI tool, with support for integration with Codex and Gemini CLI. It aims to provide standardized guidance for developers looking to set security boundaries in agent-based workflows.
