Agent Principal Identity

Agent Principal Identity is the system that assigns persistent, accountable identities to every agent operating within the CueCrux platform. Rather than treating agents as anonymous, interchangeable processes, the platform gives each agent a first-class identity with its own permission scope, budget allocation, activity history, and performance track record.

Each agent principal has a unique identifier that persists across sessions, tasks, and deployments. This identifier is attached to every action the agent takes, every event it generates in the CoreCrux event spine, and every approval request it raises through OpsCrux. When an auditor reviews the platform's activity logs, they can trace any action back to the specific agent that performed it, understanding not just what was done but who did it.

Permission scoping ensures that each agent can only perform actions appropriate to its role. A researcher agent might have read access to the corpus and the ability to submit queries but no permission to modify content or access policies. An implementer agent might have write access to specific corpus partitions but no ability to modify encryption keys or tenant configurations. These scopes are defined declaratively and enforced at the API level, preventing privilege escalation even if an agent's logic contains errors.

Budget allocations are tracked per agent principal, creating fine-grained visibility into resource consumption. Operators can see which agents are the most and least efficient, identify agents that consistently approach their budget limits, and adjust allocations based on observed patterns. Budget tracking also enables chargeback models where the cost of agent activities is attributed to the tenants or workflows that triggered them.

Historical performance metrics build up over time as each agent completes tasks. Metrics include accuracy rates for researcher agents, approval rates for actions requiring operator validation, budget efficiency scores, and error frequencies. These metrics create a track record that informs trust-based delegation decisions. An agent with a long history of accurate, efficient operation might receive broader delegated authority, while an agent with a checkered history faces more frequent approval gates.

Trust-based escalation uses the performance metrics to dynamically adjust the level of human oversight required for each agent. High-trust agents can proceed through routine decisions without pausing for approval, while low-trust agents are required to seek explicit operator approval more frequently. Trust scores evolve continuously based on recent performance, creating a self-adjusting oversight system.

For the CueCrux platform, Agent Principal Identity is what makes multi-agent orchestration safe and accountable. It provides the granular visibility and control that organisations need to deploy autonomous agents in professional settings while maintaining the human oversight that regulated environments demand.
