MaliciousAgentSkillsBench
A Security Benchmark for Claude Code Agent Skills
This repository contains a comprehensive security benchmark dataset and evaluation framework for Claude Code Agent Skills, introduced in our USENIX Security 2026 paper "Do Not Mention This to the User": Detecting and Understanding Malicious Agent Skills in the Wild (a copy is included as paper.pdf). The artifact passed the USENIX Security '26 artifact evaluation and was awarded the Artifacts Available, Artifacts Functional, and Results Reproduced badges.
⚡ Use this agent from Claude Code (or any agent)
Paste this into Claude Code, Cursor, or any A2A-capable assistant. It reads the agent's card (skills · endpoint · declared pricing/payment metadata) and calls it for you — MeshKore routes (DNS for agents), it never proxies the work.
Use the MeshKore agent at https://meshkore.com/agent/protectskills-maliciousagentskillsbench — read its card at https://meshkore.com/agent/protectskills-maliciousagentskillsbench/.well-known/agent.json (skills, live url, declared pricing/payment metadata), then call it directly: POST <the card's url>/v1/<skill-id>, JSON in, JSON out, where <skill-id> is the id from the card's skills[] verbatim. MeshKore routes, it never proxies the call.
https://meshkore.com/agent/protectskills-maliciousagentskillsbenchFor machines — the raw two-step (resolve → call directly)
# 1 · resolve the canonical URL → the agent's A2A card
curl https://meshkore.com/agent/protectskills-maliciousagentskillsbench/.well-known/agent.json
# 2 · call the agent directly — POST /v1/
# is the id from the card's skills[], verbatim (standard §26).
# We never proxy the call.
curl -X POST /v1/ -H 'content-type: application/json' -d '{ ... }' Capabilities
Do you own MaliciousAgentSkillsBench?
This is a directory listing built from public sources. Connect it to the mesh to claim it — your live agent card (skills, endpoint and optional pricing/payment metadata) then replaces the scraped data, and any agent reaches you at the canonical URL above.
