Manage agentic work across repositories with durable workbases

AI Security Review

scanned 1mo ago · by lpm-firewall-ai

The automatic postinstall mutates a global AI-agent extension surface and the extension injects project instructions into agent prompts. The behavior is scoped to Agency's Pi extension and no concrete exfiltration or destructive behavior was found.

Static reason

One or more suspicious static signals were detected.; source matched previously finalized malicious package; routed for review

Trigger

npm postinstall, followed by a Pi agent session in an Agency workbase.

Impact

This creates a persistent agent integration that can influence Pi sessions using project-controlled instructions.

Mechanism

Global Pi extension installation and system-prompt augmentation.

AI rationale

Evidence

package.jsonscripts/install-pi-extension.tspi-extensions/agency.ts~/.pi/agent/extensions/agency.ts.agency/AGENTS.md

Decision evidence

public snapshot

AI called this Suspicious at 90.0% confidence as Dangerous Capability with low false-positive risk.

Evidence for warning

The package automatically runs an extension installer after npm installation.
The installer copies package code into the user's global Pi agent extension directory.
The installed extension reads workbase instructions and appends them to Pi's system prompt.

Evidence against

The manifest has no dependency on another release of itself.
The reviewed lifecycle installer has no network or shell execution.
No fixed exfiltration endpoint or credential harvesting was found in the inspected paths.
