Transcript
Your AI agent can't investigate a breach like a junior analyst. The Anthropic-Cybersecurity-Skills repo fixes that with 817 structured skills on the agentskills.io standard. It maps skills to MITRE ATT&CK and NIST CSF 2.0, detects Kerberoasting via Sigma rules, and scopes multi-provider cloud breaches. Red-team and exploitation techniques are included, so authorized testing only — but your next investigation gets expert-level guidance.
