## Verdict summary
**Soft block: AI-agent control surface** — Warn by default; block when configured. A package installation can remove a user-controlled skill named lodestar-files from Codex or Claude directories.

- **Verdict:** AI-agent control-surface policy finding
- **Product-default install policy:** Warn by default; block when configured
- **Firewall policy:** Warn by default
- **Public report status:** Published
- **Threat category:** Soft block: AI-agent control surface
- **Selected version:** 0.18.22
- **Selected version is latest:** No
- **Analysis source:** AI Security Review (lpm-firewall-ai)

This finding concerns changes to an AI agent's instructions or configuration without explicit user action. It does not by itself establish malware intent. The CLI warns by default and blocks when configured for this policy.

AI assessment: malicious; recommendation: publish block. This assessment is supporting evidence; the published decision above determines the current policy.

LPM flags this version as an AI-agent control-surface risk. An npm postinstall hook deletes a named skill from Codex and Claude user control directories. This mutates foreign AI-agent control surfaces during installation without a user command.

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:** An npm postinstall hook deletes a named skill from Codex and Claude user control directories. This mutates foreign AI-agent control surfaces during installation without a user command.

- **Trigger:** Installing the package through npm activates postinstall.

- **Impact:** A package installation can remove a user-controlled skill named lodestar-files from Codex or Claude directories.

- **Evidence paths:** package.json, scripts/postinstall.cjs, src/managed-skill-cleanup.cjs

- **Review source:** ai\_review

- **Reviewed:** 2026-09-22T15:54:24.245Z

### AI review details

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

- **Mechanism:** The hook calls removeManagedSkill, which reads SKILL.md, accepts a matching frontmatter name, and recursively removes the corresponding directory.

- **Attack narrative:** On installation, npm runs the package's postinstall hook. That hook invokes a cleanup routine which searches user-level Codex and Claude skill roots for lodestar-files and recursively deletes each matching directory. The check only verifies that the target SKILL.md declares the same name, so installation mutates external agent configuration areas rather than limiting itself to package-owned files.

- **Rationale:** This is an unconsented automatic install-time mutation of foreign AI-agent control surfaces. The opt-out and name check do not change that the deletion is triggered by installation.

- **Files touched:** .codex/skills/lodestar-files, .claude/skills/lodestar-files

### Review decision

- **Verdict:** Malicious

- **Confidence:** 94.0%

- **Recommended action:** publish\_block

- **Intent class:** Malware

- **False-positive risk:** Low

- **Evidence for policy risk:** The package automatically runs scripts/postinstall.cjs after npm installation., The postinstall hook loads the cleanup helper and invokes it for lodestar-files without an interactive user command., The helper targets Codex and Claude skill directories under the user's home directory and recursively removes matching directories; a skill's self-declared name is the only ownership check.

- **Evidence against:** The cleanup can be disabled with LODESTAR\_DISABLE\_SKILL\_SYNC=1 and skips directories whose SKILL.md lacks the expected name.

## Affected versions and remediation

This report applies to @leviyuan/lodestar@0.18.22.

- Avoid installing @leviyuan/lodestar@0.18.22. Remove it from direct dependencies and check your lockfile for transitive copies.
- Choose an independently verified alternative or release. This report does not establish that other versions are safe.
- If this version ran, investigate the affected machine and build environment. Rotate credentials it could access and rebuild from a trusted environment.
