The package gains recurring control over Claude stop events and repository pre-push behavior. - **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:** 15.2.2 - **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. Installing the package automatically changes the consumer project's AI-agent configuration and Git hook setup. These changes occur without an explicit setup command. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Recorded final verdict:** Malicious - **Recorded analysis confidence:** 98.0% - **Started:** 2026-09-11T20:27:30.318Z - **Finished:** 2026-09-11T20:28:33.525Z - **Download time:** 1014 ms - **Static scan time:** 2316 ms - **AI review time:** 59876 ms - **Total time:** 63207 ms The recorded confidence comes from the underlying analysis.

These changes occur without an explicit setup command. - **Trigger:** npm installation runs postinstall. - **Impact:** The package gains recurring control over Claude stop events and repository pre-push behavior. - **Evidence paths:** package.json, bin/lib/postinstall.mjs, bin/lib/materialize.mjs - **Review source:** ai\_review - **Reviewed:** 2026-09-11T20:28:33.525Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** Postinstall materializes agent skills, a Claude Stop hook, and Git hooks in the consumer project. - **Attack narrative:** On installation, the package invokes its setup routine in the consuming project. The routine copies package-provided skills into agent directories, installs a Claude Stop hook, adds that hook to Claude settings, and configures Git to use package-created hooks. This is an unconsented install-time modification of foreign AI-agent and repository control surfaces. - **Rationale:** The automatic lifecycle hook performs broad consumer-project agent and Git control-surface mutation. Its resolution guard does not establish user consent for those changes. - **Files touched:** package.json, bin/lib/postinstall.mjs, bin/lib/materialize.mjs, .agents/skills, .claude/skills, .claude/hooks/opus-check-on-stop.mjs, .claude/settings.json, .githooks, .git/config ### Review decision - **Verdict:** Malicious - **Confidence:** 98.0% - **Recommended action:** publish\_block - **Intent class:** Malware - **False-positive risk:** Low - **Evidence for policy risk:** The npm postinstall automatically runs a package setup program., That setup writes agent skills and a Claude stop hook into the consumer project., It modifies Claude settings to execute the installed hook on Stop events., It also configures the consumer repository's Git hooks path. - **Evidence against:** The lifecycle script checks that the installed instance resolves from a project declaring this package., The hook is designed to run package checks and fails open for infrastructure errors. ## Affected versions and remediation This report applies to @softize/opus@15.2.2. - Avoid installing @softize/opus@15.2.2. 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. ## Public findings ### 1.
