Use when the user says /security-snapshot, /snapshot <domain>, "run a security check on X", "generate a security report for [company]", or wants a security hygiene snapshot or free lead-magnet report on a prospect''s public domain: SSL/TLS grade, HTTP security headers, SPF/DMARC email authentication, server fingerprint leaks. Passive, unauthenticated scans only. NOT for penetration testing, internal infrastructure audits, or application-layer vulnerability assessment.
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
> **`{SKILL_DIR}`** = this skill's own folder (locally: the directory this SKILL.md lives in; a served brain substitutes the real absolute path before you read this). Shared starter files live at the repo root two levels up: `{SKILL_DIR}/../..`. If a path does not resolve, name the missing file and stop — never guess another location.
When the user types /security-snapshot [domain] or asks for a security check on a prospect, run the security snapshot generator and deliver a client-ready report.
## Why this skill exists
Prospects rarely have budget for a full security audit upfront, but they will read a free one-page report that exposes real issues with their public-facing setup. This skill generates that report in under 3 minutes and opens the door for a paid follow-up on security work, AI implementation, or adjacent consulting.
## Command
```bash
python3 "{SKILL_DIR}/../../scripts/security-snapshot.py" <domain> --company "<Display Name>"
```

How to install
mdr add mycelium-hq/ai-brain-starter/security-snapshot@sha256:d3da6beea66e3fedThe line at the top of this page pins the label git:20260722.7893e72, 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.
