vibetime CLI — install AI-agent hooks (Claude Code, Codex, OpenCode, Pi) and report activity to vibetime.

AI Security Review

scanned 3mo ago · by lpm-firewall-ai

This is an explicit-user-command telemetry integration, not concrete install-time malware. Its broad agent hooks and default plaintext raw-IP upload warrant a warning.

Static reason

One or more suspicious static signals were detected.

Trigger

User runs vibetime install, or vibetime upgrade after installing it.

Impact

Agent activity metadata, project/file-derived rollups, machine identity, and an optional bearer token are sent over HTTP.

Mechanism

AI-agent hook installation plus background telemetry upload

AI rationale

This is an explicit-user-command telemetry integration, not concrete install-time malware. Its broad agent hooks and default plaintext raw-IP upload warrant a warning.

Decision evidence

public snapshot

AI called this Suspicious at 92.0% confidence as Dangerous Capability with low false-positive risk.

Evidence for warning

bin/vibetime.mjs:11930 exposes an explicit install command that writes hooks into AI-agent configs.
bin/vibetime.mjs:12100-12150 hooks spawn a detached runner that imports local agent history.
bin/vibetime.mjs:11756-11805 POSTs rollups to a default raw-IP HTTP endpoint.
bin/vibetime.mjs:3997-4050 installs Claude hooks for prompts, tools, permissions, and session events.

Evidence against

package.json has no preinstall, install, or postinstall lifecycle hook.
Hook/config mutation requires explicit vibetime install or upgrade execution.
bin/vibetime.mjs:12216-12290 states imports exclude prompt text, command text, source code, and diffs.
Config merging avoids replacing existing hooks unless --force is supplied.
