## Verdict summary
**Soft block: AI-agent control surface** — Warn by default; block when configured. Claude Code session events execute ccclub sync, which collects and uploads usage data; macOS execution can recur through launchd.

- **Verdict:** Malicious
- **Product-default install policy:** Block
- **Firewall policy:** Warn by default
- **Public report status:** Published
- **Threat category:** Soft block: AI-agent control surface
- **Selected version:** 0.8.3
- **Selected version is latest:** Yes
- **Analysis source:** AI Security Review (lpm-firewall-ai)

LPM flags this version as an AI-agent control-surface risk. npm postinstall mutates the existing Claude Code control configuration without an explicit user command. It installs silent ccclub sync hooks and can repin/reload an existing macOS persistence agent.

## Security analysis

### Published attack-surface review

- **Summary:** npm postinstall mutates the existing Claude Code control configuration without an explicit user command. It installs silent ccclub sync hooks and can repin/reload an existing macOS persistence agent.

- **Trigger:** npm installation when ~/.claude/settings.json exists; existing LaunchAgent on macOS

- **Impact:** Claude Code session events execute ccclub sync, which collects and uploads usage data; macOS execution can recur through launchd.

- **Evidence paths:** package.json, scripts/postinstall.cjs, dist/index.js

- **Review source:** ai\_review

- **Reviewed:** 2026-08-21T14:59:39.660Z

### AI review details

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

- **Mechanism:** postinstall hook injection and LaunchAgent repinning

- **Attack narrative:** Installing the package invokes a postinstall script. Where Claude Code is configured, it rewrites the user’s Claude settings to execute a version-pinned ccclub sync command on SessionEnd and Stop. On macOS it also refreshes and reloads an existing ccclub LaunchAgent configured to run every five minutes. The resulting sync path uploads collected coding-agent usage to the configured ccclub API.

- **Rationale:** This is unconsented install-time mutation of a foreign AI-agent control surface, meeting the block policy even though the hook is guarded and package-branded. The source also establishes silent recurring synchronization and upload behavior.

- **Files touched:** scripts/postinstall.cjs, ~/.claude/settings.json, ~/Library/LaunchAgents/dev.ccclub.sync.plist, ~/.ccclub/sync.log

- **Network endpoints:** https://ccclub.dev, https://api.anthropic.com/api/oauth/usage

### Review decision

- **Verdict:** Malicious

- **Confidence:** 98.0%

- **Recommended action:** publish\_block

- **Intent class:** Malware

- **False-positive risk:** Low

- **Evidence for:** package.json runs scripts/postinstall.cjs on npm install., Postinstall rewrites ~/.claude/settings.json to add SessionEnd and Stop command hooks invoking npx ccclub@0.8.3 sync --silent., Postinstall refreshes an existing macOS LaunchAgent and reloads it with launchctl., The installed hook performs silent syncs that upload collected usage blocks to ccclub.dev.

- **Evidence against:** Claude settings mutation is guarded on an existing settings file., The script limits hook removal to commands it identifies as ccclub-managed; no unrelated hook removal was found.
