Threat-model a sensitive design with STRIDE on request. Read-only analysis of threats, controls, and implementation constraints.
Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file the same grade.
What the file says
# security-architecture
For every security policy reference below, follow `${CLAUDE_PLUGIN_ROOT}/includes/knowledge.md`
("Read security policy before a security decision"): select the repository's
context format, read the complete policy from exact `CTX-SECURITY-CONTROLS`
records in HTML mode or the full Markdown controls in Markdown mode, and read
operative scope blocks when applicable. Required policy that is missing or
unreadable blocks a security decision; scope blocks alone are not full policy.
Optional, lightweight threat-modeling pass over a design before it is built. Selected when the user deliberately requests threat modeling of a sensitive design, with or without `/ca:threat-model`. Never forced on an ordinary change. Reviews architectural intent before code exists; for code already written, dispatch `security-reviewer` instead.
## Entry boundaries
Read-only: modify no project file, decision record, control or implementation.
Optional reviewers inherit this read-only analysis scope. An explanation-only
security question does not start the pass; mentioning authentication in an ordinary
change does not opt in. The user need not repeat a slash command to request it.

How to install
mdr add arbiterforge/codearbiter/security-architecture@sha256:78efb90da52d4bd4The line at the top of this page pins the label git:20261025.6e96d09, which is what most people want. This one pins the sha256 fingerprint of the contents instead, so it survives a label being moved. Either way the exact version is written to mdr.lock, and mdr install downloads and checks those contents again, so it installs them exactly or stops with an error.
