The global postinstall automatically sets up this package's own agent extension in detected client homes. Policy classifies first-party package-owned extension setup as warning-only; inspected network and check-runner behavior does not establish a separate attack.

Static reason

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

Trigger

npm global postinstall, unless VIBE_SKIP_SETUP is set.

Impact

Agent clients may load the package's card, skills, hooks, or plugin after installation.

Mechanism

The hook calls setupGlobal, which installs or registers the package's own agent surfaces in detected client homes.

AI rationale

Evidence

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

Network endpoints1

api.github.com

Decision evidence

public snapshot

AI called this Suspicious at 94.0% confidence as Dangerous Capability with medium false-positive risk.

Evidence for warning

package.json runs scripts/postinstall.js; for global installs, that hook invokes setupGlobal.
The postinstall hook skips local installs and can be disabled with VIBE_SKIP_SETUP.
setupGlobal installs surfaces for detected client homes, and installPlugin creates a local plugin tree and marketplace entry.
The indicated register.js location reads Claude plugin state; registration uses the package's local marketplace path.
GitHub requests use the fixed api.github.com endpoint with an available GitHub token.
Eval checks run a configured runner with project case inputs when the check is invoked.

Evidence against

The inspected source shows first-party agent setup during global installation, but no evidence of credential exfiltration, remote payload execution, or destructive behavior. The global hook and caller are user-scope setup for this package.

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.
