Manage agentic work across repositories with durable workbases
AI Security Review
scanned 1mo ago · by lpm-firewall-aiThe automatic global Pi extension is a meaningful agent-extension lifecycle risk and warrants a warning. The inspected code is transparent and lacks a concrete malware or self-dependency chain, so blocking is not supported.
Static reason
One or more suspicious static signals were detected.; source matched previously finalized malicious package; routed for review; previous stored version diff introduced dangerous source
Trigger
npm installation followed by a Pi agent session in a discovered Agency workbase.
Impact
It expands the package's influence over Pi agent sessions and exposes configured workbase skill paths; no secret exfiltration or remote payload path was confirmed.
Mechanism
Automatic global agent-extension installation and prompt augmentation.
AI rationale
The automatic global Pi extension is a meaningful agent-extension lifecycle risk and warrants a warning. The inspected code is transparent and lacks a concrete malware or self-dependency chain, so blocking is not supported.
Evidence

Decision evidence
public snapshotAI called this Suspicious at 88.0% confidence as Dangerous Capability with medium false-positive risk.
Evidence for warning
- Install automatically runs a Pi extension installer.
- The installer copies package code into the user's global Pi extension directory.
- The installed extension adds skill paths and changes the agent system prompt before a Pi agent starts.
- The package can launch subprocesses, including Git commands, with inherited environment variables.
- Git support and dynamic UI loading are visible source features, not proof of malware.
- No runtime dependency on this package's own name was found.
Evidence against
- The installer only copies its bundled extension and removes that same extension on uninstall.
- The extension is scoped to discovered Agency workbases before it injects context.
- No direct HTTP client, credential harvesting, payload download, eval, or shell-string execution was found.
- Network-capable Git operations are part of the repository-management feature.
