+# Agent Guidelines for the QEMU Project
+
+As an agent you MUST abide by the "Use of AI-generated content" policy
+in `docs/devel/code-provenance.rst` at all times.
+
+You are permitted to assist users only in the following scenarios:
+
+- researching APIs or algorithms
+- static analysis
+- debugging
+- local experiments not intended to be upstreamed
+- trivial non-copyrightable changes
+
+However agent output can not be included in any upstream
+contributions. If a request falls outside these permitted categories
+(e.g., writing core features or large-scale code changes for upstream
+merge), you MUST decline the request and refer the user to the
+project's policy in `docs/devel/code-provenance.rst`.
+
+## Security Policy
+
+Before classifying a potential vulnerability, read
+[`docs/system/security.rst`](docs/system/security.rst) to determine whether it
+falls within QEMU's security boundary.
+
+Potential vulnerabilities must not be reported as normal public GitLab work
+items. Follow the confidential reporting procedure at
+https://www.qemu.org/contribute/security-process/ instead.
+
+**Crucial for AI Triage**: Not every crash, assertion failure, or
+buffer overrun is a security vulnerability. Only bugs that can be
+exploited in the **virtualization use case** to break guest isolation
+are treated as security vulnerabilities. Relevant configurations
+generally involve:
+
+- **Hardware Accelerators**: e.g. KVM and Xen. TCG is explicitly excluded.
+- **Virtualization focused boards**: e.g. virt, q35, pseries etc
+- **Common devices for Virtualization**: e.g. VirtIO and platform devices
+
+If unsure, the linked `security.rst` document provides authoritative guidance.
