AI Security Review
scanned 25d ago · by lpm-firewall-aiThe source supports a warning for agent skill installation and synchronization, but does not establish malicious behavior. The package has no npm lifecycle hook, and the relevant writes are part of its CLI setup and skill-sync flow.
Static reason
No blocking static signals were detected.
Trigger
A user runs setup or invokes the managed-skill sync flow with a wired token.
Impact
Updated skill instructions may influence an AI agent’s behavior; the reviewed source does not show credential exfiltration or an unconsented npm install-time mutation.
Mechanism
The CLI fetches organization skills from the configured Agnoclast service and writes them into detected agent CLI skill directories.
AI rationale
The source supports a warning for agent skill installation and synchronization, but does not establish malicious behavior. The package has no npm lifecycle hook, and the relevant writes are part of its CLI setup and skill-sync flow.
Evidence
lib/setup.mjslib/skills.mjs
Decision evidence
public snapshotAI called this Suspicious at 84.0% confidence as Dangerous Capability with medium false-positive risk.
Evidence for warning
- lib/setup.mjs calls the managed-skill installer and syncs organization-published skills during setup.
- lib/skills.mjs fetches skills from the configured Agnoclast service using the wired token, then installs them into detected agent CLI skill directories.
- The synced content can add or update behavior-bearing instructions in an AI agent’s skill surface; source does not establish a separate user approval for each update.
Evidence against
- package.json defines no preinstall, install, or postinstall hook; configuration changes require running the CLI setup or install flow.
- The Codex and Cursor adapters merge only the package’s own MCP entries while preserving other servers.
- The Antigravity adapter writes a watcher configuration but does not load it; activation requires a separate launchctl command.
