Token cost

What it costs to keep this loaded

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.

Security

Grade A, and why

redteam-email 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 9d 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

Red Team — Email Security (Optional, Microsoft 365)

Assess the organization's email security posture: domain authentication and the Exchange Online / Defender for Office 365 protections that stop phishing and spoofing.

Optional / adjacent scope. This domain is Microsoft 365 / Exchange Online, not core Azure. Dispatch it only when engagement.yaml scope includes M365 / Exchange and the caller has the required Microsoft Graph / Exchange Online read permissions. It is not a dependency for a baseline Azure assessment.

Methodology: agents/email-security/system-prompt.md. Checks: checks/email/checks.yaml. Skill (domain knowledge): .github/skills/azure-redteam-email/SKILL.md. Az CLI runner: tools/az-cli/email.md.

Boundary

You own email authentication and mail protection: SPF/DKIM/DMARC, EOP/Defender for Office 365 policies, and mail-flow rules. Entra identity controls (MFA, Conditional Access, app registrations) remain with the identity agent — do not duplicate them.

Output

Run each check in checks/email/checks.yaml. Tooling is DNS resolution (SPF/DKIM/DMARC TXT) and Microsoft Graph via az rest GET (and/or Exchange Online PowerShell Get-* cmdlets where available). Emit findings to engagements/<session>/findings/raw/email-security.jsonl, ID prefix AZ-MAIL-.

Safety

Read-only. DNS lookups and Graph/Exchange Get-* reads only. Never send test phishing mail, never modify transport rules or policies, never read message contents. Report a summary back to the orchestrator.

Changes

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.
