AI Security Review

scanned 11d ago · by lpm-firewall-ai

The source confirms postinstall-triggered setup of first-party agent surfaces, gated to global installs and a skip variable. This fits the warning-only agent extension lifecycle category; the inspected behavior does not justify a publish block.

Static reason

High-risk behavior combination matched malicious policy.; source matched previously finalized malicious package; routed for review

Trigger

Global npm installation, unless VIBE_SKIP_SETUP is set.

Impact

Agent homes may receive the package’s card, skills, hooks, or plugin registration without a separate setup command.

Mechanism

The postinstall script invokes setupGlobal, which installs package surfaces for detected agent clients.

AI rationale

Evidence

package.jsonscripts/postinstall.jsdist/install/global.jsdist/install/plugin.jsdist/install/register.js

Decision evidence

public snapshot

AI called this Suspicious at 88.0% confidence as Dangerous Capability with medium false-positive risk.

Evidence for warning

The postinstall hook runs a setup script, gated to global installs unless VIBE_SKIP_SETUP is set.
That script invokes setupGlobal, which installs surfaces for every detected client home.
The setup targets Claude, Codex, and Hermes locations; this is first-party agent integration setup.

Evidence against

The postinstall setup is limited to global installs and can be skipped with VIBE_SKIP_SETUP.
The package has an explicit plugin install path; no source evidence inspected establishes credential theft or a separate malicious payload.

3 * vibe for the Claude desktop app — an MCP Bundle server that is nothing but a cable to the

4 * `vibe` CLI. Every tool runs `vibe <command> --json` in the project folder the user picked at

5 * install time (VIBE_PROJECT_DIR) and returns the JSON. The verdict stays in the CLI; this

6 * surface is for the interview, the approval, the judgement and the handoff — not for writing code.

7 *

8 * MCP over stdio is newline-delimited JSON-RPC 2.0. Three methods matter here: initialize,

9 * tools/list, tools/call. No SDK: the protocol subset is small and the bundle stays dependency-free.
