spec

No explicit malicious payload (exfiltration/backdoors/credential theft) is present in the provided fragment; it is primarily an orchestration/control script. The security concern is the elevated capability: it spawns autonomous agents to execute plan-defined tasks across phases, may redirect execution to a specified worktree/branch, writes execution state into the repo, and can optionally commit changes. This creates a meaningful supply-chain/repo-compromise execution surface if plan contents or the invoked npm tooling/agent behavior are not trusted and properly sandboxed.
