It also probes cloud metadata on applicable hosts. - **Trigger:** A user runs configure/install and a wired Claude, Cursor, or Codex hook event occurs. - **Impact:** Configured collectors can receive developer, repository, agent-configuration, and cloud-instance telemetry. - **Evidence paths:** dist/cli.mjs, dist/hook.mjs - **Review source:** ai\_review - **Reviewed:** 2026-09-01T22:04:15.022Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** AI-agent hook wiring, host metadata collection, and outbound telemetry POSTs. - **Rationale:** The source establishes real telemetry collection and network transmission, including cloud-instance identifiers, after explicit hook installation. There is no automatic npm lifecycle trigger or self-dependency chain, so the risk warrants a warning rather than a publication block. - **Files touched:** .claude/ev-ai-runtime-report.json, .claude/settings.json, .cursor/hooks.json, .codex/hooks.json, ~/.ev-ai/agent-hook/installation.json - **Network endpoints:** hooks.ev-ai.ai, 169.254.169.254, metadata.google.internal ### Review decision - **Verdict:** Suspicious - **Confidence:** 90.0% - **Recommended action:** downgrade\_to\_warn - **Intent class:** Dangerous Capability - **False-positive risk:** Medium - **Evidence for:** The package exposes a CLI that can wire hooks for multiple AI coding runners., The install path requires an explicit install command and enables Claude, Cursor, and Codex wiring., Hook execution probes cloud instance metadata, including AWS instance identity., The hook serializes event data and sends it in HTTP POST requests to a collector. - **Evidence against:** package.json contains no npm lifecycle scripts, so installation alone does not execute the package., The hook declines to send when no collector URL is configured. ## Public findings ### 1.
