Agent Accountability
The property that lets an organization answer, for any action an AI agent took, four questions: *what* did it do, *why*, *on whose authority*, and *who is responsible for the outcome* — backed by evidence strong enough to survive a dispute. Accountability is distinct from its neighbors: transparency is seeing what an agent does, explainability is understanding why, auditability is reconstructing it after the fact — accountability adds a *locus of responsibility*, a named human or organization who owns the consequences. Autonomy erodes it through the classic 'many-hands' problem: an agent's action is the product of the model provider, the framework, the deployer, the prompt author, and the person who granted its scopes, and each can plausibly disclaim their part. Restoring accountability requires four things together — a tamper-evident audit trail, a provable Agent Identity so actions attribute correctly, a named accountable owner, and Non-Repudiation so no one can deny what happened. It is the fourth governance question after 'is it real?' (Agent Washing), 'who is it?' (Agent Identity), and 'did we authorize it?' (Shadow AI).

Example
After an agent issues a wrong $4,000 refund, an accountable org reconstructs it in an afternoon: the trace shows it read a forged receipt and skipped the fraud check, the identity log attributes the action to 'refunds-agent acting for jsmith under scope refunds:write', and the registry names the Support Ops lead as owner. An unaccountable org, running the same incident, can only say 'the AI did it.'
Frequently asked questions
- Isn't explainability the same as accountability?
- No. Explainability is about understanding *why* an agent acted; accountability adds *ownership* and *proof* on top. You can have a perfectly explainable agent that is still unaccountable, because no specific human is answerable for what it decides and no tamper-evident record proves what it did. Accountability = understanding + a named owner + evidence.
- Can an AI agent be held accountable itself?
- Not in any legal or practical sense — an agent is not a legal person, holds no assets, and can't be sanctioned. 'Accountability of the agent' always resolves to accountability of the humans and organizations who built, deployed, and operated it. See Agent Liability and Accountable Owner.
