AI Security Review
scanned 2mo ago · by lpm-firewall-aiThis is an automatic mutation of a consumer AI-agent control surface, creating a real lifecycle risk. Its guarded, non-overwriting and package-aligned implementation does not establish malware behavior.
Static reason
One or more suspicious static signals were detected.
Trigger
npm dependency installation runs postinstall.
Impact
Can influence Codex or Claude behavior in consumer projects that lack those files.
Mechanism
Postinstall creation of AGENTS.md and CLAUDE.md pointers.
AI rationale
This is an automatic mutation of a consumer AI-agent control surface, creating a real lifecycle risk. Its guarded, non-overwriting and package-aligned implementation does not establish malware behavior.
Evidence
package.jsonbin/init.jstemplates/AGENTS.stub.mdAGENTS.mdCLAUDE.mdtemplates/CLAUDE.stub.md
Decision evidence
public snapshotAI called this Suspicious at 88.0% confidence as Dangerous Capability with low false-positive risk.
Evidence for warning
- The automatic postinstall hook runs the initializer during dependency installation.
- The initializer locates consumer project roots and targets Codex and Claude instruction files there.
- The installed stubs instruct AI agents to load package-controlled rules that can change on later installs.
Evidence against
- The initializer skips existing instruction files unless an explicit force option is used.
- No source evidence of network access, credential collection, shell execution, or payload download was found.
- The written files are narrow design-system guidance pointers rather than arbitrary project-file changes.
