### AI overview

The guide recommends layered controls to reduce open source supply chain risk: delay package adoption with a 48-hour age gate, disable install scripts except for approved packages, and enforce lockfiles; pin CI dependencies and container images to immutable identifiers while scheduling updates. Scope and rotate credentials, use FIDO2 or passkeys for maintainers, protect developer machines, and centrally allowlist extensions, recognizing approved extensions can still be compromised. For AI agents, limit permissions and sandbox runtime access, verify and pin MCP servers, treat external prompt input and agent output as untrusted, and scan new dependencies both at installation and in pull requests. Audit logs, signed SBOMs, and rehearsed credential rotation support incident response. The text notes that cooldowns can miss packages undetected beyond the delay, while pinning delays upstream fixes unless teams deliberately update. It also describes Aikido Security products for install-time and repository detection.
