What exactly did you approve?<\/h2>\n

If you approve an AI agent deleting one file, have you also approved it deleting another? An AI agent is an AI system that can plan and take actions toward a goal. OWASP recommends binding approval to the exact action: changing the target or other action details requires new approval. Think of permission as a ticket for a particular journey, with a destination and an expiry.<\/p>\n

Authorization means deciding whether an actor is allowed to perform an action. For an agent, that decision should happen in the execution component\u2014the part of the system that actually carries out the request\u2014outside the agent\u2019s reasoning. An agent saying that the user agreed is insufficient evidence of permission.<\/p>\n

What should the approval cover?<\/h2>\n

OWASP recommends recording who is acting, which operation will run, its target, its parameters\u2014the details controlling the operation\u2014and when approval expires. Before execution, the system should check that approval matches the current request, remains valid and has not already been used. A general \u201cuser confirmed\u201d flag cannot establish all of those facts.<\/p>\n

The check and the act of marking approval as used should happen together, as one indivisible step. Otherwise, simultaneous requests could reuse the same permission. This is replay protection: preventing an authorization from being accepted again after its intended use. OWASP also recommends short-lived authorization for irreversible operations.<\/p>\n

One file, one decision<\/h2>\n

In this hypothetical example, an agent proposes deleting a particular draft file. You review the preview and approve that deletion. Before carrying it out, the execution component checks that the approval belongs to you and matches that file and operation. If the agent instead requests deletion of a folder, the earlier approval does not cover it.<\/p>\n

If the original deletion request arrives again after approval has been consumed, that approval should not authorize another execution. A useful design question is whether the system can enforce both boundaries: changed requests need new approval, and repeated requests cannot reuse spent approval.<\/p>\n

\"An
Approval covers one matching action. A changed target or a repeated request must not pass using the same permission.<\/figcaption><\/figure>\n

Why more prompts are not enough<\/h2>\n

In an August 27, 2026 blog post, NIST warned about consent fatigue: repeated approval requests can condition people to click \u201callow\u201d without examining them. Human oversight therefore has limits. OWASP recommends setting autonomy boundaries according to action risk, alongside explicit approval and previews for high-impact actions.<\/p>\n

Consider keeping an agent\u2019s underlying permissions narrow and making consequential approvals specific enough to understand. When assessing an approval flow, ask: can this permission authorize a different target, changed details or another execution? For a single approved action, the useful boundary is concrete: one matching request, within its validity period, accepted once.<\/p>\n
