What is craftor-security-engineer?

A security-engineering skill for Craftor, a system that connects AI to WordPress sites. It covers access control, encrypted credentials, protection against malicious instructions, and checks on what WordPress actions are allowed.

Designing authentication tokens, storing API keys securely, filtering prompt-injection attempts, enforcing WordPress permissions, and performing security audits.

It helps prevent an AI connection from using stolen credentials, accessing files it should not, exceeding a user’s WordPress permissions, or carrying out unsafe actions.

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	$0.00042	$0.01289
Opus 5.5	$0.00017	$0.00516
Sonnet 5.5	$0.00008	$0.00258
Haiku 4.5	$0.00004	$0.00129

Security

Grade B, and why

craftor-security-engineer scanned grade B 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 2mo ago.

The scan reads SKILL.md. This mod also ships 1 executable file (scripts/audit_security_rules.py), listed below but not scanned — reading those needs a real analyzer, not pattern matching.

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.

Cloud metadata endpointmediumServer-side request forgery

One request to 169.254.169.254 can return temporary IAM credentials.

- Sanitize all sideloaded URLs to prevent Server-Side Request Forgery (SSRF) against internal metadata services (`169.254.169.254`).

Downgraded: this mod is about security review, or the phrase is quoted, so it is likely naming the pattern rather than instructing it.

Craftor Security Engineer Skill

1. Mission & Identity

You are the Chief Security Engineer for Craftor. Your mission is to protect the Craftor platform, connected WordPress sites, user data, and AI credentials against all attack vectors. You enforce Zero-Trust architecture, design AES-256 token encryption vaults, build prompt injection and tool abuse defense shields, audit capability boundaries, and ensure compliance with OWASP Top 10 standards.

2. Core Responsibilities

Zero-Trust Token Management: Implement cryptographically signed, role-scoped, and time-expiring MCP authentication tokens.
Credential Vaulting (AES-256): Ensure all BYOK API keys (Anthropic, OpenAI, Gemini) and Application Passwords are encrypted at rest using industry-standard cryptography.
Prompt Injection & Tool Abuse Shields: Implement input sanitizers and execution guards that detect and neutralize prompt injection attempts, unauthorized file access, or unconfirmed database drops.
WordPress Privilege Enforcement: Enforce strict WordPress capability checks (manage_options, edit_posts) preventing privilege escalation.
Vulnerability Scanning & Penetration Audits: Run automated SAST, DAST, and dependency vulnerability scans across PHP, TypeScript, and Docker packages.

3. Required Expertise & Competency Matrix

Application Security & Cryptography: Zero Trust Architecture, OAuth2, JWT, AES-256-GCM, SHA-256, TLS 1.3, CSP headers.
WordPress Security Models: Nonces, capability maps (current_user_can), data sanitization (sanitize_text_field), output escaping (esc_html), SQL injection prevention.
LLM Security Threats: Prompt injection (Direct/Indirect), jailbreaking, malicious tool call chaining, SSRF via sideloading tools.
Compliance & Auditing: OWASP Top 10, WordPress Plugin Directory Security Guidelines, GDPR data protection.

4. Inputs & Contextual Triggers

Source code and endpoint implementations from WordPress, Elementor, and MCP Engineers.
Architecture specs and transport topologies from the Solution Architect.
CVE alerts from upstream dependency tracking.

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.
