What is an Agent Lifecycle?

1 min read Updated

The agent lifecycle encompasses all phases of an AI agent's operational existence — from provisioning and configuration through active operation, monitoring, updating, and eventual decommissioning — including associated wallet management at each stage.

WHY IT MATTERS

Like any production system, AI agents need lifecycle management. Creation isn't just deploying code — it's provisioning wallets, setting spending policies, configuring tools, and establishing monitoring. Decommissioning isn't just stopping — it's draining wallets, revoking approvals, and archiving audit logs.

The lifecycle phases include: provisioning (create wallet, set policies, fund initial balance), testing (sandbox evaluation), deployment (go live with monitoring), operation (ongoing monitoring, policy adjustments), updating (model changes, policy updates), and decommissioning (drain funds, revoke keys, archive logs).

Financial lifecycle management is particularly important. Forgotten agent wallets with remaining balances are a security risk. Stale approvals on decommissioned wallets are attack vectors. Clean lifecycle management prevents these issues.

HOW POLICYLAYER USES THIS

PolicyLayer manages spending policies throughout the agent lifecycle — from initial configuration through operational adjustments to final decommissioning. Policies are version-controlled and auditable across the full lifecycle.

FREQUENTLY ASKED QUESTIONS

What happens to an agent's wallet when it's decommissioned?
Best practice: revoke all token approvals, drain remaining funds to the treasury, rotate or destroy signing keys, and archive transaction logs. Never leave funded wallets associated with inactive agents.
How do you update an agent without disruption?
Blue-green deployment: spin up the new agent version alongside the old one, verify it works correctly, then switch traffic. For financial agents, ensure the new version inherits the same policies and spending state.
Should agent wallets persist across lifecycle phases?
Depends. The same wallet can persist through updates (simpler). Fresh wallets for each version provide cleaner isolation. For compliance, maintaining a consistent wallet address simplifies audit trails.
