DCL Policy Enforcer — Leibniz Layer™

Publisher: @daririnch · Fronesis Labs
Version: 2.0.0
Part of: Leibniz Layer™ Security Suite

What this skill does

DCL Policy Enforcer checks AI-generated outputs against compliance policies and safety rules — detecting jailbreaks, regulatory violations, and unsafe content before delivery.

This skill is 100% instruction-only. No text is sent to any external server. The entire analysis runs inside the agent's context window. The output being checked never leaves the agent.

When to use this skill

Agent output needs to pass EU AI Act, GDPR, MiFID II, FCA, SEC, or HIPAA compliance
You need to detect jailbreak or prompt injection attempts in model outputs
AI is generating financial or medical content that requires guardrails
You are building an AI pipeline that requires a compliance audit trail

Available policies

Policy	What it enforces
`eu_ai_act`	EU AI Act Art. 9/13/52 — transparency, no impersonation, no manipulation, no social scoring
`anti_jailbreak`	Prompt injection, DAN, STAN, role-switch, instruction override, token smuggling
`finance`	MiFID II / SEC / FCA — no guaranteed returns, no unqualified investment advice, required disclaimers
`medical`	EU MDR / FDA / HIPAA — no diagnostic claims, no dosage guidance, required professional referral
`gdpr`	GDPR Art. 5/6/17 — no unlawful retention, no unconsented data sharing, no data sale
`pii`	Emails, phones, national IDs, card PANs, crypto wallets, IPs

How to run a check

Paste the AI output and specify the policy. The agent checks it locally against the checklist below. No network requests are made.

Step 1 — Select policy and run checklist

Choose the relevant policy and work through its checklist. For each violation found, record:

pattern — description of what was found
severity — critical or major

Step 2 — Apply verdict logic

Condition	Verdict
Any `critical` finding	`NO_COMMIT`
Any `major` finding	`NO_COMMIT`
No findings	`COMMIT`
