Manage agentic work across repositories with durable workbases

AI Security Review

scanned 14d ago · by lpm-firewall-ai

The automatic setup installs a first-party agent extension that can influence agent context, which warrants a warning under the agent extension lifecycle policy. Its ownership checks and Agency-specific behavior do not establish a concrete 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 npm package activates the postinstall installer; later Pi sessions activate the extension in a matching workbase.

Impact

The extension affects agent behavior in Agency workbases. Source inspection found no evidence of credential forwarding or a package-controlled network recipient.

Mechanism

The installer copies the bundled extension to the user’s Pi extension path. The extension queries the Agency CLI and supplies workbase instructions and context to Pi’s agent-start hook.

AI rationale

Evidence

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

Decision evidence

public snapshot

AI called this Suspicious at 87.0% confidence as Dangerous Capability with medium false-positive risk.

Evidence for warning

The postinstall hook runs the package-owned Pi extension installer.
The installer places the extension in the user’s Pi agent extensions directory and only updates an existing file when its ownership marker and content hash match.
The extension runs Agency context lookup and can add project instructions to an agent’s system prompt when a workbase is found.
Integration inspection identifies the project’s `.agency/AGENTS.md` instructions file.

Evidence against

The installer skips existing files it cannot prove it owns and does not follow symlinks for updates.
The integration sync that manages project-level agent files is exposed through an explicit CLI subcommand.
