TypeScript CLI for Twist
AI Security Review
scanned 10d ago · by lpm-firewall-aiThe postinstall hook silently rewrites existing package-owned Twist CLI skills under supported agent directories. This guarded first-party agent extension lifecycle behavior warrants a warning, but the inspected source does not establish a broader attack.
Static reason
High-risk behavior combination matched malicious policy.; source matched previously finalized malicious package; routed for review; source fingerprint signature matched known malicious package; routed for review
Trigger
The package's postinstall hook runs during installation.
Impact
An installed agent's Twist CLI instructions can change automatically when this package is installed or updated.
Mechanism
The hook checks supported agent skill paths and rewrites the existing Twist CLI skill file with the package's skill content.
AI rationale
The postinstall hook silently rewrites existing package-owned Twist CLI skills under supported agent directories. This guarded first-party agent extension lifecycle behavior warrants a warning, but the inspected source does not establish a broader attack.
Evidence

Decision evidence
public snapshotAI called this Suspicious at 95.0% confidence as Dangerous Capability with medium false-positive risk.
Evidence for warning
- The package runs a postinstall script that imports its built postinstall module.
- The postinstall module automatically updates installed skills without surfacing errors.
- The update helper skips agents without an installed skill, then updates those that exist.
- The installer writes the package's skill content to the existing skill file.
- The default install path is under the user's home directory in configured agent skill folders.
Evidence against
- The installer skips absent skill files, and the files it updates are the package's own Twist CLI skills.
