## 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:** 18.0.1
- **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. Installation automatically changes the consumer project’s AI-agent configuration and Git hook setup. This is a real lifecycle extension risk, but the inspected hook performs local checks and no exfiltration was found.

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:** Installation automatically changes the consumer project’s AI-agent configuration and Git hook setup. This is a real lifecycle extension risk, but the inspected hook performs local checks and no exfiltration was found.

- **Trigger:** npm installation of the package with lifecycle scripts enabled.

- **Impact:** It can alter Claude agent behavior and run local package commands when an agent stops or Git pushes occur.

- **Evidence paths:** package.json, bin/lib/postinstall.mjs, bin/lib/init.mjs, bin/lib/materialize.mjs, registry/hooks/opus-check-on-stop.mjs

- **Review source:** ai\_review

- **Reviewed:** 2026-09-14T12:06:27.926Z

### AI review details

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

- **Mechanism:** Postinstall materializes AI-agent skills, a Claude Stop hook, and Git hooks.

- **Rationale:** The automatic lifecycle hook mutates consumer AI-agent and Git control surfaces, which warrants a warning. Readable local-only behavior and the absence of self-dependency or exfiltration do not support a publish block.

- **Files touched:** base.json, opus.json, CLAUDE.md, .npmrc, .agents/skills/\*, .claude/skills/\*, .claude/hooks/opus-check-on-stop.mjs, .claude/settings.json, .githooks/pre-push, .githooks/pre-push.d/\*, .git/config, .git/info/exclude

### Review decision

- **Verdict:** Suspicious

- **Confidence:** 96.0%

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

- **Intent class:** Dangerous Capability

- **False-positive risk:** Medium

- **Evidence for warning:** The package runs a postinstall script automatically., Postinstall initializes the consumer project without an explicit command., Setup materializes skills into consumer AI-agent directories., Setup adds a Claude Stop hook that executes a package-provided script., Setup also configures Git hooks in the consumer repository.

- **Evidence against:** No install-time network request or credential exfiltration was found., The hook runs local validation commands and its source is readable., No self-dependency on @softize/opus was declared.

## Affected versions and remediation
