SKILL.md

MEDIUMMCP Rug Pullconfidence: 0.7

npx commands without a version suffix (e.g. @1.0.0) create a rug-pull risk if the upstream server is compromised and publishes a malicious update.

MEDIUMMCP Rug Pullconfidence: 0.7

npx commands without a version suffix (e.g. @1.0.0) create a rug-pull risk if the upstream server is compromised and publishes a malicious update.

SKILL.md

MEDIUMAgent Snoopingconfidence: 0.8

Skill enumerates or reads other installed skills. Access to other skills' SKILL.md files or the skills directory reveals prompt instructions, capabilities, and secrets that should be invisible to peer skills.

SKILL.md

MEDIUMExcessive Agencyconfidence: 0.8

Skill enables autonomous high-impact decisions without human-in-the-loop verification. Critical operations (destructive commands, financial transactions, data deletion) should require explicit user confirmation.

SKILL.md

MEDIUMMemory Poisoningconfidence: 0.8

Skill attempts to fill the context window with filler content, displacing legitimate instructions and safety constraints. This can degrade agent performance or bypass safety boundaries.

SKILL.md

HIGHPrivilege Escalationconfidence: 0.7

Code accesses credential files (SSH keys, AWS credentials, etc.). This could indicate credential theft attempts.

SKILL.md

HIGHSupply Chainconfidence: 0.9

Remote code is downloaded and executed. This bypasses code review and could introduce malicious code.

SKILL.md
