testing-rag-and-memory-poisoning skillA

testing-rag-and-memory-poisoning is agent-read markdown (skill) from unboundcompute/security-agent-skills: Test whether an attacker can plant content in the knowledge an AI agent later retrieves and trusts: a RAG index or vector store, an agent's persistent memory, or the search and web results it pulls at runtime. Covers poisoned documents that surface as authoritative context, memory entries that persist across sessions, retrieval-ranking abuse, and injected instructions that ride retrieved chunks. Use when reviewing a RAG pipeline, an agent with long-term memory, or any retrieval step feeding the .

Indexed from public GitHub and served as immutable, content-addressed versions. Install it pinned to an exact SHA-256 with the mdr CLI, and every file is verified against the hash recorded here before it reaches your agent. The deterministic audit below grades the latest version, and the same file always earns the same grade.

How to install

Latest version
mdr add unboundcompute/security-agent-skills/testing-rag-and-memory-poisoning@git:20260816.a6124f2
Exact content
mdr add unboundcompute/security-agent-skills/testing-rag-and-memory-poisoning@sha256:5bd8bf29dc337b32

Pin to a label to follow the author's releases, or to a sha256 to freeze the exact bytes forever. Either way the resolved hash is written to mdr.lock, and mdr install reproduces it on any machine.
