Dynamic Object Manipulation & Modeling API - A complete front-end toolkit.
AI Security Review
scanned 11d ago · by lpm-firewall-aiSource inspection found a postinstall hook that may add first-party Claude Code assistance files after user confirmation, plus an explicit CLI setup path. No evidence inspected establishes an active attack; the guarded agent setup capability warrants a warning.
Static reason
High-risk behavior combination matched malicious policy.; source matched previously finalized malicious package; routed for review
Trigger
Package installation reaches postinstall in a node_modules context outside CI, followed by user acceptance at the prompt.
Impact
This can add first-party project guidance and configuration files for Claude Code; inspected evidence does not establish credential theft, remote execution, or unconsented control-surface mutation.
Mechanism
The script copies CLAUDE.md and related assistance files into the project only after prompting and only when destination paths are absent.
AI rationale
Source inspection found a postinstall hook that may add first-party Claude Code assistance files after user confirmation, plus an explicit CLI setup path. No evidence inspected establishes an active attack; the guarded agent setup capability warrants a warning.

Decision evidence
public snapshotAI called this Suspicious at 89.0% confidence as Dangerous Capability with medium false-positive risk.
Evidence for warning
- package.json runs a postinstall script.
- The postinstall script asks before copying AI assistance files and stops when the user declines.
- Postinstall copies the package's CLAUDE.md only when the project does not already have one.
- The CLI setup also copies package-provided assistance files only when the user continues and destination files are absent.
- The flagged view template contains ordinary view lifecycle hooks and example comments.
