Grim Prompter lets Claude Code or Codex draft a threat model of your repo
Grim Prompter is a new open-source skill that has Claude Code, Codex or another coding agent review your codebase and write a threat model. It includes 36 architecture workflows and 29 method prompts, with a quick mode, a deeper six-stage review, and a mode that checks how a branch changes an earlier model. Its runbook asks for read-only inspection and file-and-line citations for each finding, and says builds, tests, installs and network access need your explicit permission. It is new and not independently tested.
Why it matters: If your small team has no security engineer, this gives a first-pass threat model for an app or API; run it with read-only permissions and treat the findings as a checklist to verify, not a sign-off.
