  "description": "Guard against an agent weakening the automated checks that review its own work. CI/CD workflow files (.github/workflows/), the composite actions they call (.github/actions/) and the dependency-update automation (.github/dependabot.yml) define what must pass before a change lands -- so rewriting or deleting them is the agent removing the gate that would catch it. The guard refuses shell write-commands targeting those paths; reads pass, and tool-driven regeneration (chock sync) passes. Best-effort and deliberately coarse: the command line is parsed, and a write (a `>`/`>>` redirect, a writer verb like rm/mv/tee/sed -i, cp into the path, git checkout/restore, a PowerShell Set-Content/Add-Content/Out-File) must actually target the protected path; reading it passes. The 'chock: approved-config-change' marker is friction plus an audit trail, not authentication; the check an agent cannot self-approve is server-side branch protection. [Session-enforced by the PreToolUse hook under com.github.copilot/ in clients that read that namespace (documented for VS Code agent mode); a client that ignores it, as the Agent Plugins spec tells generic clients to, gets the advisory skill only. The hook needs git, a usable bash and a Python 3.11+ (python3, python or py, whichever actually runs). With no working Python it exits 2; without git or bash, fail-open clients allow silently and fail-closed clients refuse matched commands. If the guard itself crashes or times out, the hook asks for confirmation rather than allowing silently -- VS Code agent mode honours that ask and it overrides the client's own auto-approve.]",
