Anthropic Cybersecurity Skills — 754 Skills Library

Main

• Use it as a skills corpus: point your agent to the repo’s skill directory, then search by domain (e.g., DFIR, cloud, web) instead of free-text prompting.

• Leverage the five-framework mapping when you need to explain “why this step exists” (ATT&CK/CSF/ATLAS/D3FEND/AI RMF) to auditors or security leads.

• Start with a narrow workflow (one incident type or one cloud provider) and only then broaden to the full 26-domain library to keep agent planning focused.

Source-backed notes

• README states the repo contains 754 structured cybersecurity skills across 26 domains and follows the agentskills.io standard.
