Manage agentic work across repositories with durable workbases
AI Security Review
scanned 1mo ago · by lpm-firewall-aiThe package automatically modifies a global AI-agent extension surface during postinstall. This is a real lifecycle risk but does not meet the policy threshold for a malicious publish block.
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 postinstall, followed by starting Pi in an Agency workbase.
Impact
It changes an AI agent control surface without an explicit setup command; no exfiltration or remote payload behavior was confirmed.
Mechanism
Automatic global Pi extension installation and system-prompt augmentation.
AI rationale
The package automatically modifies a global AI-agent extension surface during postinstall. This is a real lifecycle risk but does not meet the policy threshold for a malicious publish block.
Evidence
package.jsonscripts/install-pi-extension.tspi-extensions/agency.ts~/.pi/agent/extensions/agency.ts<workbase>/.agency/AGENTS.md
Decision evidence
public snapshotAI called this Suspicious at 94.0% confidence as Dangerous Capability with low false-positive risk.
Evidence for warning
- Its postinstall hook automatically installs a Pi agent extension.
- The installer creates and copies code into the user's Pi extension directory.
- The installed extension adds Agency and workbase instructions to an agent system prompt.
Evidence against
- No runtime dependency on this package itself is declared.
- No credential collection, HTTP client, or data exfiltration path was found in the inspected lifecycle and extension code.
- The extension only activates after it finds and validates an Agency workbase.
