Manage agentic work across repositories with durable workbases
AI Security Review
scanned 1mo ago · by lpm-firewall-aiThe package has an automatic postinstall hook that modifies a global AI-agent extension path and injects workbase context at runtime. The behavior is scoped and source-visible, with no confirmed theft, remote execution, or broad foreign-control-surface mutation.
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 a Pi agent session in an Agency workbase.
Impact
The package changes an AI-agent extension surface without an explicit setup command; its runtime behavior can influence Pi agent context for Agency workbases.
Mechanism
Automatic first-party Pi extension installation and scoped prompt/skill integration.
AI rationale
The package has an automatic postinstall hook that modifies a global AI-agent extension path and injects workbase context at runtime. The behavior is scoped and source-visible, with no confirmed theft, remote execution, or broad foreign-control-surface mutation.
Evidence
package.jsonscripts/install-pi-extension.tspi-extensions/agency.ts~/.pi/agent/extensions/agency.ts
Decision evidence
public snapshotAI called this Suspicious at 91.0% confidence as Dangerous Capability with low false-positive risk.
Evidence for warning
- The automatic postinstall hook installs a Pi agent extension.
- The installer creates and writes to the user-wide Pi extensions directory.
- The installed extension injects workbase instructions into Pi's system prompt and exposes skills from several agent-tool directories.
Evidence against
- The lifecycle installer only copies the package's static extension and removes that same path on uninstall.
- The extension activates only after it finds an Agency workbase and validates Agency context.
- No source evidence of network exfiltration, self-dependency, payload download, or credential harvesting was found.
