Which agents the Act covers
The EU AI Act (Reg. 2024/1689) is risk-based. Most general-purpose agents are out of scope unless they are placed on the market as a high-risk system or deployed inside a high-risk use. The high-risk categories that commonly involve agents are in Annex III: recruitment and worker management, credit scoring, access to essential services, law enforcement, and safety components of products.
If your agent operates in one of those areas, the obligations below attach — and most of them attach to the deployer, not the model provider.
The obligations that matter (Art. 9–17)
For high-risk systems the Act requires, among others:
- Art. 9 — Risk management system: a continuous process to identify and mitigate known and foreseeable risks.
- Art. 10 — Data governance: training and evaluation data must be relevant, representative, and free of errors/bias to the extent relevant.
- Art. 11 — Technical documentation: evidence the system meets the requirements.
- Art. 12 — Record-keeping: logs that enable traceability of each run.
- Art. 14 — Human oversight: a natural person can understand, monitor, and interrupt the system.
- Art. 15 — Accuracy, robustness, cybersecurity: the system performs as intended under error, perturbation, or attack.
A guardrail layer — tool-call risk ratings, approval gates, and run logs — is decision-support that helps you evidence Art. 9, 12, 14, and 15. It is not the certificate itself.
Deployer vs provider
This split is the part teams miss. The provider builds and documents the model; the deployer puts it into a specific high-risk use and carries the operational duties (Art. 26 for deployers of high-risk systems). If you are a small team deploying an off-the-shelf model as a recruiting screener, you are the deployer and you own Art. 9/14/15 in practice.
Current timeline (Digital Omnibus)
Effective dates have shifted. General-purpose AI rules and several obligations took effect in 2024–2025; many Annex III high-risk obligations have been delayed by the Digital Omnibus and currently track toward 2 December 2027. Dates move — confirm the current effective date against the Official Journal and the European Commission before committing a compliance plan to a deadline.
What a guardrail layer gives you
Concretely, a guardrail layer can:
- Produce the run logs Art. 12 wants.
- Put a human-approval gate on high-risk tool calls (Art. 14).
- Make tool-call risk visible and rated (Art. 9, 15).
It narrows the gap between "we think it's safe" and "we can show it." That is the whole job of preventive controls under the Act.
