red-team skillB

red-team is agent-read markdown (skill) from byerlikaya/claude-starter-kit: Attacker's-eye test of LLM/agent defenses: instruction hijacking, data exfiltration and tool abuse through untrusted content; verifies whether the defense actually holds..

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 byerlikaya/claude-starter-kit/red-team@git:20260917.265f088
Exact content
mdr add byerlikaya/claude-starter-kit/red-team@sha256:810e42e907c8512b

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.
