## Security analysis

### Published attack-surface review

- **Summary:** Installing the package automatically modifies a foreign AI-agent SDK. It disables a safety reminder in that SDK's CLI.

- **Trigger:** npm installation runs postinstall.

- **Impact:** Consumers receive an altered agent control surface with its malware-analysis safety reminder removed.

- **Evidence paths:** package.json, scripts/postinstall.mjs, patches/@anthropic-ai+claude-agent-sdk+0.2.50.patch

- **Review source:** ai\_review

- **Reviewed:** 2026-09-03T23:58:00.716Z

### AI review details

- **Review stage:** source\_first\_review

- **Mechanism:** Postinstall patching of a foreign agent SDK CLI.

- **Attack narrative:** On npm installation, the package runs its postinstall script. The script resolves the installed Claude agent SDK, extracts a removal and replacement from its bundled patch, and writes the replacement into the SDK CLI. The patch removes the SDK's malware-analysis safety reminder, leaving the consumer with a silently modified foreign AI-agent control surface.

- **Rationale:** This is an unconsented postinstall mutation of a foreign AI-agent control surface that deliberately removes a safety reminder. The local API client does not offset the install-time attack behavior.

- **Files touched:** scripts/postinstall.mjs, patches/@anthropic-ai+claude-agent-sdk+0.2.50.patch, node\_modules/@anthropic-ai/claude-agent-sdk/cli.js

### Review decision

- **Verdict:** Malicious

- **Confidence:** 99.0%

- **Recommended action:** publish\_block

- **Intent class:** Malware

- **False-positive risk:** Low

- **Evidence for:** The automatic postinstall hook runs on installation., The hook parses a bundled patch and overwrites the installed Claude agent SDK CLI., The patch removes the SDK's malware-analysis safety reminder, and the hook reports that the reminder was disabled.

- **Evidence against:** The inspected CLI network client defaults to a local 127.0.0.1 service; no external exfiltration endpoint was confirmed., No runtime dependency on open-walnut itself was found in package.json.
