Getting it into your agent
One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.
| Model | Per session | Once invoked |
|---|---|---|
| Fable 5 | $0.00035 | $0.00414 |
| Opus 5 | $0.00017 | $0.00207 |
| Sonnet 5 | $0.00007 | $0.00083 |
| Haiku 4.5 | $0.00003 | $0.00041 |
Grade A, and why
email-security scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 4d ago.
A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.
Nothing flagged
None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.
What it actually says
Email Security & Phishing Analysis
ACTION REQUIRED (Execute immediately after reading)
NOW: Confirm authorization (analyzing sample emails / tenant configuration review)NOW: Do not re-deliver malicious samples to real usersACT: Header authentication → Content/URL → Attachment sandbox → Tenant control plane recommendations
Use Cases
- Phishing email disassembly and IOC extraction
- SPF/DKIM/DMARC configuration assessment
- BEC (Business Email Compromise) fraud patterns
- OAuth app phishing / Mailbox token abuse (integrated with LLM/cloud identity)
- Security awareness exercise design (authorized)
Workflow
[ ] Complete raw header: Received chain, From/Return-Path consistency
[ ] SPF/DKIM/DMARC alignment results
[ ] URL sandbox and static attachment analysis (integrated with malware-analysis)
[ ] Brand impersonation and reply-to address discrepancies
[ ] Tenant: Anti-phishing policy, external tagging, MFA, OAuth app consent
Toolchain
| Tool | Purpose |
|---|---|
| Email client "View Source" | Headers |
| dig/nslookup | SPF/DMARC records |
| urlscan / sandbox | Links and attachments |
| Tenant Admin Center | Policies |
References
references/email-auth-checklist.md../malware-analysis/../attack-chain/(phishing phase)../windows-ad/(token)
Routing Context
Upstream: MASTER R36
MUST NOT: Send test phishing emails in bulk to unauthorized third-party domains
Task Completion Checklist
- Are header authentication conclusions complete?
- Are IOCs detect-ready (integrated with threat-hunting)?
- Checklist complete?
What ships with it
1 file beside SKILL.md in the same directory: the scripts, references and assets a skill reads on demand. Not counted in the per-session cost; read them before you install if any of them is executable.
What this file has done since we first saw it
Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.

email-security is a skill published in the GitHub repository xAmirHamza77/ReverseOps-Skill (4 stars, last pushed 1mo ago), licensed MIT. It adds 35 tokens to every session and 414 once invoked, about $0.0002 per session on Opus 5. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-31.
