Manage agentic work across repositories with durable workbases
AI Security Review
scanned 1mo ago · by lpm-firewall-aiThis is a real automatic global agent-extension installation risk, so it warrants a warning. The source supports a first-party extension setup rather than a concrete malicious chain.
Static reason
One or more suspicious static signals were detected.; source matched previously finalized malicious package; routed for review
Trigger
npm postinstall
Impact
Pi sessions can receive Agency workbase instructions and context without a separate setup command.
Mechanism
Global first-party Pi extension installation and system-prompt augmentation
AI rationale
This is a real automatic global agent-extension installation risk, so it warrants a warning. The source supports a first-party extension setup rather than a concrete malicious chain.
Evidence
package.jsonscripts/install-pi-extension.tspi-extensions/agency.ts~/.pi/agent/extensions/agency.ts
Decision evidence
public snapshotAI called this Suspicious at 94.0% confidence as Dangerous Capability with low false-positive risk.
Evidence for warning
- The postinstall hook automatically installs a Pi agent extension.
- The installer copies the extension to the user-wide Pi extensions directory.
- The installed extension runs on Pi agent events and appends Agency-controlled context to system prompts.
Evidence against
- The manifest has no runtime dependency on this package itself.
- No direct HTTP client, socket, credential harvesting, or secret exfiltration code was found in the inspected TypeScript sources.
- The extension is named for this package and its uninstall hook removes that same extension.
