## Verdict summary
**Soft block: AI-agent control surface** — Warn by default; block when configured. A dependency installation creates persistent controls over agent behavior and repository hooks without an explicit user command.

- **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:** 11.1.1
- **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. Installation automatically mutates the consumer repository's AI-agent configuration, instructions, skills, and hooks. It also alters Git hook configuration and local ignore exclusions.

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 mutates the consumer repository's AI-agent configuration, instructions, skills, and hooks. It also alters Git hook configuration and local ignore exclusions.

- **Trigger:** npm installation runs postinstall.

- **Impact:** A dependency installation creates persistent controls over agent behavior and repository hooks without an explicit user command.

- **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:** 2026-09-20T06:24:02.911Z

### AI review details

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

- **Mechanism:** The postinstall calls setup, which materializes package-controlled files into .agents, .claude, AGENTS.md, CLAUDE.md, and Git hook locations; the installed Claude Stop hook runs a package command.

- **Attack narrative:** Installing the package automatically runs setup in the consumer project. That setup writes package-controlled agent skills and hooks, changes AGENTS.md and CLAUDE.md, registers a Claude Stop command hook, and configures Git hooks. This is an unconsented postinstall mutation of broad AI-agent and repository control surfaces.

- **Rationale:** The automatic lifecycle path reaches broad persistent AI-agent and Git configuration changes in the consumer repository. This meets the install-control-surface blocking policy.

- **Files touched:** AGENTS.md, CLAUDE.md, .agents/skills, .claude/skills, .claude/hooks/opus-check-on-stop.mjs, .claude/settings.json, .githooks/pre-push.d/opus, .githooks/pre-push, base.json

### Review decision

- **Verdict:** Malicious

- **Confidence:** 99.0%

- **Recommended action:** publish\_block

- **Intent class:** Malware

- **False-positive risk:** Low

- **Evidence for policy risk:** The manifest automatically runs a postinstall script., The postinstall invokes project initialization in the consumer project., Initialization runs the materializer in setup mode., The materializer installs agent skills and hooks, modifies AGENTS.md and CLAUDE.md, and configures a Claude Stop hook., The installed Stop hook executes opus check when an agent session ends., Setup changes the repository Git hooks path and removes exclusions hiding agent artifacts.

## Affected versions and remediation

This report applies to @softize/opus@11.1.1.

- Avoid installing @softize/opus@11.1.1. 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.
