Perform a focused security review of changed code in a Cratis application — injection, authentication and authorization, data exposure, secrets, event-sourcing-specific exposure, and the frontend — and report findings by risk. Use when asked for a security review or audit. Do not use to implement authentication and do not report a policy preference as a framework contract.
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
# Cratis security review Event sourcing changes the shape of a security review. A mistake in an ordinary application is a bug you fix; a secret written into an append is a fact that lives in the log forever and cannot be edited out. The event-sourcing section below is the one that is specific to this stack, and it is the one worth reading first. ## Verified product sources | Package | Purpose | | --- | --- | | `Cratis.Arc.Chronicle` | `[NotAudited]` in `Cratis.Arc.Chronicle.Commands`; the `ARCCHR0009` analyzer | | `Cratis.Chronicle` | `[PII]`, `[Subject]`, redaction, namespace isolation | | `Cratis.Chronicle` | `[Encrypted]` in `Cratis.Chronicle.ProtectedValues`; analyzers `CHR0052`, `CHR0053` | | `Cratis.Arc.Core` | Authorization filters, `CommandResult.Unauthorized` | Every Arc check is cited in references/arc-boundaries.md. Reverify against the owning product repository before asserting a framework guarantee this file does not already state. ## When to run this review without being asked The orchestrating agents and the PR-review prompt run it unconditionally as the last gate. When you are shipping directly — one agent, one branch — run it …

How to install
mdr add cratis/ai/cratis-security-review@sha256:e81d844f4f79471fThe line at the top of this page pins the label git:20261017.b02cf93, 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.
