TL;DR: AI agent rollouts can consume 5 to 30 times the tokens of comparable chatbot interactions, and some enterprises have already blown through budgets by 4 to 11 times within 90 days, according to WorkOS and Gartner analysis. The governance gap starts in authorization: without per-agent identity, tool-level scoping, and session boundaries, cost attribution stays invisible and unusable.

Editorial analysis by NHI Mgmt Group, based on content published by WorkOS: “The token bill is an identity problem”.

Key questions

Q: What breaks when AI agents are connected through personal accounts or shared credentials?

A: Shared or personal credentials break accountability, lifecycle control, and revocation.

Q: Why do AI agent programmes need tool-level authorization for cost control?

A: Because the tool boundary is also the spend boundary.

Q: How do organisations know if AI governance is actually working?

A: They should be able to reconstruct a live interaction from identity context, policy outcome, accessed resources, and enforcement evidence.

Practitioner guidance

  • Issue distinct identities for each agent Separate agent credentials from human user accounts and from other agents so every model call can be attributed to one runtime actor.
  • Scope tools at the authorization layer Grant each agent access only to the tools it needs, because tool-level authorization is also the cost boundary for token spend.
  • Bind access to task sessions Use session-scoped tokens that expire with the task so spend cannot continue after the visible workflow is complete.

Bottom line: AI agent token spend becomes difficult to govern when identities are shared, access scopes are broad, and sessions are not enforced at task boundaries.

Token spend is now an identity governance problem, not a finance afterthought. The article is right to treat cost attribution as the visible symptom of a deeper authorization design flaw. When agents share credentials or inherit human identities, the organisation loses the ability to bind spend to a specific actor, workflow, or owner. The practical implication is that chargeback fails wherever identity boundaries are vague.

A few things that frame the scale:

  • Claude Code-assisted commits leaked secrets at a rate of 3.2%, more than double the human-only baseline of 1.5%, with peaks reaching 31 secrets per 1,000 commits in August 2025, according to the State of Secrets Sprawl 2026.

A question worth separating out:

Q: What should security teams do when an AI agent keeps consuming tokens after the task ends?

A: Treat that as a session-boundary failure. The agent should lose access when the task closes, and any credential that survives beyond the workflow should be reviewed as over-persistent. Persistent access is what turns a bounded task into open-ended spend.
