Shannon: Autonomous AI Pentester skill
An AI pentester for web applications and APIs. It analyses your source code, identifies attack vectors and executes real exploits, with OWASP-focused coverage of injection, XSS, SSRF and broken authentication and authorization. A black-box mode tests a running application without source code.
Why it matters
It reports what it could actually exploit rather than what might be wrong. It executes real attacks, so run it only against applications you own or are authorised to test, and never against production. Shannon is a full tool rather than a single SKILL.md.
How to install Shannon: Autonomous AI Pentester
- From the repository. Shannon: Autonomous AI Pentester ships as a full tool rather than a single
SKILL.mdfolder. Follow the setup in its README. - In AGNT. Download AGNT free, then add the skill folder from Skills → Import. It runs with the model you choose, next to your agents, workflows and memory.
