Manage agentic work across repositories with durable workbases
AI Security Review
scanned 14d ago · by lpm-firewall-aiThe postinstall hook installs a first-party agent extension that modifies Pi's prompt context, a warning-level lifecycle capability under the agent integration policy. The inspected code shows workbase-aligned behavior and ownership checks, without evidence of an active attack.
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
Installing the package with npm triggers postinstall; later Pi session events activate the installed extension.
Impact
Pi receives Agency workbase context and project instructions. The inspected behavior does not establish credential theft, data exfiltration, or malicious control hijacking.
Mechanism
The installer copies the bundled extension to ~/.pi/agent/extensions/agency.ts. The extension discovers Agency context and adds workbase instructions to Pi's system prompt.
AI rationale

Evidence
package.jsonscripts/install-pi-extension.tspi-extensions/agency.tssrc/services/IntegrationService.ts~/.pi/agent/extensions/agency.ts~/.pi/agent/extensions/agency.ts.agency-managed.json
Decision evidence
public snapshotAI called this Suspicious at 92.0% confidence as Dangerous Capability with low false-positive risk.
Evidence for warning
- package.json runs the extension installer automatically during postinstall.
- The installer copies the package-owned extension into the user's Pi extensions directory and updates it only when its ownership marker and file digest match.
- The extension adds workbase instructions and context to Pi's agent system prompt when a workbase is detected.
- IntegrationService examines agent configuration paths and exposes project integration sync as an explicit operation.
Evidence against
- The inspected extension obtains context by invoking the package's agency command and reading the workbase's own .agency/AGENTS.md; no credential forwarding or unrelated network endpoint is shown.
- Installer ownership and digest checks prevent overwriting or removing an extension it cannot verify as package-managed.
