## 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:** 1.1.205
- **Selected version is latest:** Yes
- **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.

Source inspection confirms an automatic postinstall write of a bundled Claude skill, with no guard against overwriting an existing skill. This is a guarded-scope extension lifecycle risk warranting a warning; the inspected source does not establish a broader malicious attack.

## Latest scan
- **Scanner version:** rust-scanner-worker-schema-1
- **Recorded final verdict:** Suspicious
- **Recorded analysis confidence:** 97.0%
- **Started:** 2026-10-11T14:06:39.567Z

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:** The npm postinstall hook installs a bundled Claude skill into the user’s skills directory. This creates a limited agent-extension lifecycle risk because the copy can replace files in an existing skill directory.

- **Trigger:** Installing the package through npm runs its postinstall hook.

- **Impact:** The bundled skill can change Claude’s response behavior when active, and an existing skill with the same name can be overwritten.

- **Evidence paths:** package.json, scripts/install-skills.cjs, .claude/skills/leanchy/SKILL.md

- **Review source:** ai\_review

- **Reviewed:** 2026-10-11T14:07:32.267Z

### AI review details

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

- **Mechanism:** The script copies files from the package’s .claude/skills directory into the user’s Claude skills directory without checking whether the destination skill already exists.

- **Rationale:** Source inspection confirms an automatic postinstall write of a bundled Claude skill, with no guard against overwriting an existing skill. This is a guarded-scope extension lifecycle risk warranting a warning; the inspected source does not establish a broader malicious attack.

- **Files touched:** ~/.claude/skills/leanchy/SKILL.md

### Review decision

- **Verdict:** Suspicious

- **Confidence:** 97.0%

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

- **Intent class:** Dangerous Capability

- **False-positive risk:** Medium

- **Evidence for warning:** package.json runs scripts/install-skills.cjs from postinstall., The installer copies bundled skill files into the user’s Claude skills directory, including over existing files., The bundled skill directs Claude’s response style while active., The plugin handler is called by the plugin install command; it is separate from the postinstall installer., The headless print path installs configured plugins during a CLI run., The indicated init and insights locations describe user-facing project guidance and skill usage., The plugin manager location loads installed plugins for display., The inspected binary and utility locations begin with launch or import setup; those excerpts do not establish additional attack behavior.

- **Evidence against:** The install hook copies one bundled skill directory; inspected code does not show network transfer or execution of the skill during installation., The remaining cited locations do not establish a broader agent configuration write or a separate malicious chain.

## Affected versions and remediation
