PIOS Positioning

PIOS is an AI Project Execution Contract.

It defines deterministic phase gates and artifact checks so AI-assisted projects can finish with verifiable state transitions.

What PIOS Is

• A tool-agnostic execution contract for software repositories
• A CLI-backed gatekeeper for phase transitions (pios validate)
• A set of artifact templates for project state, plan, and tasks

What PIOS Is Not

• Not an agent runtime platform
• Not a model orchestration layer
• Not a memory backend, vector store, or hosted control plane

PIOS vs Runtime Infrastructure

Runtime platforms execute model/tool loops. PIOS defines completion criteria and validates whether repository artifacts satisfy those criteria.

Use runtime infrastructure to do the work. Use PIOS to prove the work is done.

Core Outcomes

PIOS optimizes for:

• Finishability
• Portability
• Measurability
• Trust
