Expands the Security Features Summary slide with two missing security pillars.

Changes

  • Supply Chain Integrity — distinguishes classic (SHA-pinned Actions at compile time) from agentic (protected files blocking CI/CD config tampering)
  • GitHub Guard — surfaces min-integrity guard policies, secrecy/integrity metadata on safe output messages, and the automatic min-integrity: approved default for public repositories
Original prompt

Update slides

  • security features slide: add supply chain integrity (classic/agentic)
  • github guard integrity secrecy protection

💡 You can make Copilot smarter by setting up custom instructions, customizing its development environment and configuring Model Context Protocol (MCP) servers. Learn more Copilot coding agent tips in the docs.
