AgentLink local agent CLI

AI Security Review

scanned 11d ago · by lpm-firewall-ai

The global install hook can stage and activate a newer runtime when prior adoption is complete, so the guarded lifecycle capability warrants a warning. The flagged agent integration locations inspected access session and project-memory paths and did not establish broader agent configuration mutation.

Static reason

One or more suspicious static signals were detected.

Trigger

Global npm installation when a completed version-store adoption exists and the package version is newer.

Impact

The migrated AgentLink runtime may be replaced with the validated package version.

Mechanism

The postinstall bridge fetches a runtime manifest, prepares a bundle, and updates the version pointer; manifest overrides are restricted to loopback.

AI rationale

Evidence

package.jsonscripts/install-bridge.cjsdist/install-bridge.jsdist/runtime-release.js

Decision evidence

public snapshot

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

Evidence for warning

The npm postinstall runs an installer bridge; that hook runs its migration only for global installs.
The bridge skips unless version-store adoption is complete and the package version is newer, then stages a runtime and updates its version pointer.
A manifest URL override must be loopback, and the manifest validates supported package, platform, architecture, and bundle fields.
The Codex and Claude integration locations inspected resolve session and project-memory paths; they do not show config mutation.
Service persistence is exposed through an explicit CLI service install command.

Evidence against

A global npm postinstall can fetch and stage a package runtime and modify the active version pointer when migration conditions are met.
