Security Architect

Security Architect is a skill for Claude Code, Codex from daffy0208/ai-dev-standards. It costs 43 tokens per session (5,179 once invoked), scanned A, original, MIT.

A security-design guide covering threat analysis, secure architecture, secure coding, and regulatory requirements.

In plain words
What is it for?
Use it to model threats, review authentication and authorization, check code for common vulnerabilities, and assess requirements such as GDPR, HIPAA, SOC 2, or PCI DSS.
Why use it?
It helps teams find attack risks and compliance gaps while designing and building a system, instead of addressing them only after release.

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

Security Architect scanned grade A with 1 finding 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 8d 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.

Security Architect

Overview

Security Architect is a consolidated skill that covers the complete security lifecycle: threat modeling, secure design principles, secure coding practices, and regulatory compliance. It ensures security is integrated from the start, not bolted on at the end.

Consolidated from:

  • threat-modeling - STRIDE threat analysis and risk assessment
  • security-first-design - Security principles and secure design patterns
  • secure-coding-review - OWASP Top 10 and vulnerability detection
  • compliance-validator - GDPR, HIPAA, SOC2, PCI-DSS compliance

When to Use This Skill

Use Security Architect when:

  • Starting a new project (design phase)
  • Conducting security architecture review
  • Reviewing code for security vulnerabilities
  • Ensuring regulatory compliance
  • Responding to security incidents
  • Planning for security certifications (SOC2, ISO 27001)
  • Designing authentication and authorization systems

Key Capabilities

Threat Modeling (from threat-modeling)

  • Apply STRIDE methodology for threat identification
  • Assess risk levels (Likelihood × Impact)
  • Create threat models and mitigation plans
  • Identify attack surfaces and trust boundaries

Security Design (from security-first-design)

  • Apply security principles (Defense in Depth, Least Privilege, Zero Trust)
  • Design secure authentication and authorization
  • Implement encryption and key management
  • Design secure APIs and data protection

Secure Coding (from secure-coding-review)

  • Review code against OWASP Top 10
  • Detect injection vulnerabilities (SQL, XSS, command)
  • Identify broken authentication and access control
  • Ensure secure data handling and validation

Compliance (from compliance-validator)

  • Ensure GDPR, HIPAA, CCPA, SOC2, PCI-DSS compliance
  • Implement data subject rights (access, erasure, portability)
  • Design audit logging and retention policies
  • Configure encryption and access controls

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 Architect is a skill published in the GitHub repository daffy0208/ai-dev-standards (36 stars, last pushed 8mo ago), licensed MIT. It adds 43 tokens to every session and 5,179 once invoked, about $0.0002 per session on Opus 5. A static security scan graded it A with 1 finding (makes network calls). No closer match exists in the catalogue, so it is treated as the original; first seen 2026-09-03.
