@vatio-ai/skills@1.6.0
Agent skills for building and improving a Vatio agent from your coding agent: Claude Code, Codex, Cursor, Gemini CLI, Copilot and any agent that reads SKILL.md
AI Security Review
scanned 25d ago · by lpm-firewall-aiThe package’s explicit CLI performs first-party skill setup in the project’s agent directories, which warrants a warning for agent capability mutation. No automatic lifecycle trigger or concrete malicious behavior was established.
Static reason
No blocking static signals were detected.
Trigger
A user runs the exposed vatio-skills command.
Impact
The project’s coding agents can use the installed skills. No confirmed malicious effect was identified.
Mechanism
The command copies bundled skill directories into .agents/skills and .claude/skills, replacing existing copies; it removes a legacy skill only when its content identifies it as the package’s former skill.
AI rationale
The package’s explicit CLI performs first-party skill setup in the project’s agent directories, which warrants a warning for agent capability mutation. No automatic lifecycle trigger or concrete malicious behavior was established.
Evidence
.agents/skills.claude/skills
Decision evidence
public snapshotAI called this Suspicious at 89.0% confidence as Dangerous Capability with low false-positive risk.
Evidence for warning
- The package exposes bin/install.mjs as the vatio-skills command.
- When invoked, the installer copies its bundled skills into the project’s .agents/skills and .claude/skills directories, replacing existing copies.
- The installer removes a renamed skill only when its SKILL.md identifies it as the old vatio-new skill.
Evidence against
- package.json declares no lifecycle scripts, so the installer is not configured to run automatically during installation.
- The inspected installer has no network or credential-handling behavior.
