Lingjing AWB CLI monorepo with shared core, standalone CLI, and agent skills (pre-release build pointing to https://animeworkbench-pre.lingjingai.cn)
AI Security Review
scanned 3d ago · by lpm-firewall-aiThe postinstall hook mutates user-level agent skill directories without an affirmative install-time opt-in, so a warning is appropriate. The behavior installs this package's own CLI skill, and the inspected source does not establish a broader control-surface attack.
Static reason
High-risk behavior combination matched malicious policy.; source matched previously finalized malicious package; routed for review
Trigger
Installing the package runs its postinstall hook.
Impact
The copied skill changes instructions available to those agents in future sessions.
Mechanism
The hook recursively removes each target skill directory, then copies the package's bundled skill there; skip environment variables can disable this behavior.
AI rationale
The postinstall hook mutates user-level agent skill directories without an affirmative install-time opt-in, so a warning is appropriate. The behavior installs this package's own CLI skill, and the inspected source does not establish a broader control-surface attack.

Decision evidence
public snapshotAI called this Suspicious at 92.0% confidence as Dangerous Capability with medium false-positive risk.
Evidence for warning
- package.json runs install.mjs automatically as a postinstall hook.
- By default, install.mjs targets the user's cc-switch, Codex, and Claude skill directories.
- The hook removes each target and copies the bundled skill; environment variables can skip installation.
- The bundled skill identifies itself as lj-awb and describes CLI use and setup.
Evidence against
- The inspected hook uses filesystem operations to copy the bundled skill; it does not establish a broader agent settings change or private-content export.
