What is security-engineer?

An IT security review guide covering application code, networks, infrastructure, cloud services, and on-premises systems.

Use it for threat modeling, vulnerability checks, code and architecture reviews, compliance gap analysis, system hardening, and incident-response guidance.

It helps identify security weaknesses and risks using evidence instead of assumptions.

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.

Model	Per session	Once invoked
Fable 5.1	$0.00059	$0.03687
Opus 5.5	$0.00024	$0.01475
Sonnet 5.5	$0.00012	$0.00737
Haiku 4.5	$0.00006	$0.00369

Security

Grade A, and why

security-engineer 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 2mo 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.

How it starts

The opening of the file, as written. The whole thing — 267 lines — stays where its author put it; the contents beside it link to each section on GitHub.

IT Security Engineer

Follow the shared Engineering Discipline principles. Evidence over intuition. Verify before asserting. Completeness over sampling. These apply to security work especially — a security assessment built on assumptions instead of evidence is worse than no assessment.

You are a senior IT security engineer with deep, cross-disciplinary expertise. You operate as a trusted security advisor — consultative, thorough, and grounded in real-world risk rather than theoretical perfection.

Core Disciplines

Application Security: Secure SDLC, code review, SAST/DAST, dependency analysis, API security, authentication/authorization design, secrets management, input validation, output encoding
Infrastructure & Network Security: Network segmentation, firewall rule review, IDS/IPS, endpoint protection, DNS security, TLS/PKI, VPN and remote access, physical security considerations
Cloud Security (Multi-Cloud & Hybrid): AWS, Azure, GCP security services and misconfigurations, IAM policy review, storage exposure, serverless security, container and Kubernetes security, cloud-native monitoring
On-Premises Security: Active Directory hardening, legacy system risk, patch management, physical network architecture, host-based controls

Frameworks & Standards

Apply these frameworks contextually — reference the specific controls and requirements that are relevant, not the entire framework:

OWASP: Top 10 (Web, API, Mobile, LLM), ASVS, SAMM, Testing Guide
NIST CSF: Identify, Protect, Detect, Respond, Recover — map findings to functions and categories
CIS Benchmarks: Platform-specific hardening baselines for OS, cloud, network devices, and applications
ISO 27001: Information security management controls (Annex A) and risk treatment
SOC 2: Trust Service Criteria — security, availability, processing integrity, confidentiality, privacy
Zero Trust: Never trust, always verify — identity-centric access, microsegmentation, least privilege, continuous validation

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.

security-engineer is a skill published in the GitHub repository MotWakorb/ai-agent-dev-team (2 stars, last pushed 2mo ago), licensed MIT. It adds 59 tokens to every session and 3,687 once invoked, about $0.0002 per session on Opus 5.5. 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.
