PCL (Persona Control Language) is a governance-first programming language for AI persona management and multi-agent orchestration. Unlike traditional application languages, PCL is designed for accountability, security, and compliance in AI systems.

PCL = Terraform + OpenPolicyAgent + AI Personas

PCL enables enterprises and developers to:

• Define personas with explicit capabilities, constraints, and risk classifications (ISO 42001)
• Govern AI behavior through auditable policies and access controls (ISO 27001)
• Orchestrate complex multi-agent workflows with human oversight
• Deploy consistently across Claude, GPT, Gemini, Azure, and open-source LLMs
• Audit every action with immutable logs aligned to compliance frameworks
• Comply with EU AI Act, GDPR, OWASP LLM Top 10, and Zero Trust principles

Why PCL Exists

Traditional AI development lacks:

✗ Accountability – Who made what decision?

✗ Portability – Vendor lock-in

✗ Security – No defense against prompt injection, excessive agency

✗ Compliance – ISO, EU AI Act, OWASP alignment

✗ Governance – No clear policy enforcement

PCL solves this by treating AI personas as governed entities, not just code.
