Audit playbook module for email and SMS/OTP flows, covering outbound spoofing protection evidence (SPF/DKIM/DMARC artifacts), sending-infrastructure and notification-content injection, inbound-mail processing attack surface, verification and magic-link bypasses, and OTP/SMS brute-force, enumeration, and abuse controls.
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
## Scope & Objectives ### Objective Audit every code path and repository artifact that sends mail or SMS, receives mail or ESP webhooks, mints or consumes email-verification tokens, magic links, or OTP codes, and every flow that changes a user's email address or phone number. For each finding produce: file:line evidence of the flawed construction, a static-first reproduction recipe, a severity with rationale, and a framework-correct fix. DNS-level conclusions drawn from repo artifacts must be labeled as artifact-based; live DNS confirmation is marked requires-network. ### In Scope | Class | Typical finding | Primary CWE | |---|---|---| | Outbound spoofing protection | No SPF record artifact, `+all`/`?all` terminator, include-chain bloat past 10 lookups, no DKIM selector rotation evidence, DMARC absent or frozen at `p=none` forever on auth-email domains | CWE-345 | | Sending-infrastructure markers | SMTP/provider credentials in code or config (pointer -> SECRETS module), user-controlled display-From enabling phishing-via-your-product, Reply-To hijack in notifications | CWE-93 | …

How to install
mdr add as-foss/aegis-skills/aegis-email-sms@sha256:5f9d4094b2aaf327The line at the top of this page pins the label git:20260826.9702747, 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.
