AgentLink local agent CLI

AI Security Review

scanned 3d ago · by lpm-firewall-ai

Source inspection found no concrete attack behavior. The install-time migration is gated, and the flagged persistence is tied to explicit service setup.

Static reason

One or more suspicious static signals were detected.; previous stored version diff introduced dangerous source

Trigger

The bridge is gated to global npm installation and prior completed version-store adoption; service persistence requires the explicit service install command.

Impact

No attack impact was established in the inspected source.

Mechanism

The hook prepares a newer AgentLink runtime under those gates. The service command writes user-level auto-start configuration.

AI rationale

Source inspection found no concrete attack behavior. The install-time migration is gated, and the flagged persistence is tied to explicit service setup.

Decision evidence

public snapshot

AI called this Clean at 90.0% confidence as Benign with low false-positive risk.

Evidence for AI clean decision

The postinstall hook runs only for global npm installs; its migration helper skips unless the version store is already adopted and the prior migration completed.
The reviewed Codex, Claude, and memory paths point to agent session or memory data, while the other flagged excerpts handle project files, Git status, or session data.
The reviewed Copilot bridge communicates with a local child agent over a stream; no attack behavior was identified in the inspected excerpt.
Auto-start persistence is exposed through the explicit service install command and writes service configuration to user-level locations.
