AI Security Review
scanned 11d ago · by lpm-firewall-aiInstallation automatically adds this package's bundled skills to the user's Codex skills directory, creating an agent extension lifecycle risk. The inspected code supports a warning, but does not establish a broader control-surface attack or malicious behavior.
Static reason
High-risk behavior combination matched malicious policy.; source matched previously finalized malicious package; routed for review; previous stored version diff introduced dangerous source
Trigger
Installing the package through npm, unless the skip environment variable is set or installation occurs from the package directory.
Impact
The bundled skills become available to Codex after installation.
Mechanism
The hook copies bundled skill directories into the configured destination, defaulting to the user's Codex skills directory; modified or unmanaged existing targets are skipped.
AI rationale
Installation automatically adds this package's bundled skills to the user's Codex skills directory, creating an agent extension lifecycle risk. The inspected code supports a warning, but does not establish a broader control-surface attack or malicious behavior.
Evidence
package.jsonscripts/postinstall.mjsdist/skill/skill-manager.js
Decision evidence
public snapshotAI called this Suspicious at 91.0% confidence as Dangerous Capability with medium false-positive risk.
Evidence for warning
- package.json runs scripts/postinstall.mjs during installation.
- The postinstall imports the skill manager and automatically installs bundled skills unless skipped or installing from the package directory.
- The default Codex destination is the user's .codex/skills directory.
- The manager copies bundled skill files there and replaces an existing target only when it is managed and unmodified.
Evidence against
- The lifecycle operation installs this package's bundled skills; the source does not show a remote skill download or an unrelated broad agent configuration change.
