What is PCL?
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.
