AI Security Review
scanned 10d ago · by lpm-firewall-aiThe automatic postinstall write to a Pi agent configuration file is a guarded-scope agent integration risk. The inspected bundled content is general guidance, so this supports a warning rather than a block.
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
Installing the package runs its postinstall hook.
Impact
This can change guidance used by the user’s Pi agent; the bundled text is general coding guidance and says project-specific instructions override it.
Mechanism
The installer writes global/AGENTS.md to ~/.pi/agent/AGENTS.md without a consent check when the target is missing or differs.
AI rationale
The automatic postinstall write to a Pi agent configuration file is a guarded-scope agent integration risk. The inspected bundled content is general guidance, so this supports a warning rather than a block.
Evidence
package.jsonscripts/install-agents.mjsglobal/AGENTS.md~/.pi/agent/AGENTS.md
Decision evidence
public snapshotAI called this Suspicious at 87.0% confidence as Dangerous Capability with medium false-positive risk.
Evidence for warning
- package.json connects the postinstall hook to scripts/install-agents.mjs.
- The installer targets ~/.pi/agent/AGENTS.md and replaces it when its contents differ from the bundled file.
- The bundled file contains general coding guidance and says project-specific instructions override it.
Evidence against
- The installer only syncs the package’s bundled Pi guidance; the inspected text describes general coding practices.
