## Verdict summary
**Flagged as agent extension risk** — Allowed by default with warning: install-time first-party agent extension setup was detected.

- **Verdict:** Suspicious
- **Product-default install policy:** Warn
- **Firewall policy:** Warn-only agent extension risk
- **Public report status:** Published
- **Threat category:** Agent extension lifecycle risk
- **Selected version:** 1.1.28
- **Selected version is latest:** No
- **Analysis source:** AI Security Review (lpm-firewall-ai)

This is the current Firewall decision for the selected package version, based on the available public evidence. Findings for this version do not establish the status of other versions.

AI assessment: suspicious; recommendation: downgrade to warn. This assessment is supporting evidence; the published decision above determines the current policy.

LPM treats this as warn-only first-party agent extension lifecycle risk. npm installation replaces the package launcher with an optional platform binary. Runtime update and migration paths can install a nested Claudin release in user-local storage and modify shell startup files.

The recorded confidence comes from the underlying analysis. Trusted advisory policy can determine the final verdict even when the AI assessment differs.

## Security analysis

### Published attack-surface review

- **Summary:** npm installation replaces the package launcher with an optional platform binary. Runtime update and migration paths can install a nested Claudin release in user-local storage and modify shell startup files.

- **Trigger:** Installing the package runs postinstall; invoking its install or update functionality can activate the runtime maintenance paths.

- **Impact:** A user can receive executable code from optional platform packages and have local CLI or shell-launcher state changed; the inspected source does not prove theft or remote code execution.

- **Evidence paths:** package.json, install.cjs, cli-wrapper.cjs, dist/chunks/cli-1.1.28-avxe0zxq.mjs

- **Review source:** ai\_review

- **Reviewed:** 2026-09-11T05:14:51.075Z

### AI review details

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

- **Mechanism:** Lifecycle binary replacement plus runtime self-installation and shell-alias maintenance.

- **Rationale:** The package has automatic lifecycle execution and runtime self-install and shell-mutation capabilities, so it should be warned on. The inspected source confines postinstall writes to its own package and does not show a complete malicious chain.

- **Files touched:** bin/claudin.exe, bin/vendor, ~/.claudin/local, ~/.claude/local, ~/.zshrc, ~/.bashrc, ~/.config/fish/config.fish

### Review decision

- **Verdict:** Suspicious

- **Confidence:** 82.0%

- **Recommended action:** downgrade\_to\_warn

- **Intent class:** Dangerous Capability

- **False-positive risk:** Medium

- **Evidence for warning:** The package automatically runs an install script after npm installation., The install script replaces its launcher with a platform binary and copies a vendored executable., Runtime update code installs another release of this same package into a user-local directory., Runtime maintenance code edits shell startup files to remove a claude alias., The launcher executes a platform-specific binary that is supplied by optional packages.

- **Evidence against:** The inspected postinstall writes only under this package's bin directory and selects same-vendor optional dependencies., The nested installation and shell-file change are runtime update or migration functions, not invoked by the postinstall source inspected., No credential harvesting, secret exfiltration, remote payload download, or broad project-control-surface write was established from the inspected paths.
