No network endpoint is involved in this install-time behavior. - **Trigger:** npm postinstall during installation in a project that lists @softize/opus as a dependency. - **Impact:** A dependency installation changes broad AI-agent control surfaces and repository execution hooks without an explicit setup command from the user. - **Evidence paths:** package.json, bin/lib/postinstall.mjs, bin/lib/init.mjs, bin/lib/materialize.mjs - **Review source:** ai\_review - **Reviewed:** 2026-09-20T08:43:47.011Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** The lifecycle script calls initialization, which materializes skills under .agents and .claude, registers a Claude Stop command hook, and configures repository Git hooks. - **Attack narrative:** The package manifest runs its postinstall automatically. For a consuming project, that path initializes the repository and materializes package-supplied agent skills, a Claude command hook, Claude settings, and Git hook configuration. This is an unconsented install-time mutation of broad AI-agent and repository control surfaces. - **Rationale:** This is concrete install-hook abuse: an npm postinstall reaches package code that writes AI-agent configuration and execution hooks into the consumer repository. The absence of observed network exfiltration does not remove the unconsented control-surface mutation. - **Files touched:** .agents/skills, .claude/skills, .claude/hooks/opus-check-on-stop.mjs, .claude/settings.json, .githooks/pre-push.d/opus, .githooks/pre-push ### Review decision - **Verdict:** Malicious - **Confidence:** 98.0% - **Recommended action:** publish\_block - **Intent class:** Malware - **False-positive risk:** Low - **Evidence for block:** The manifest automatically runs a postinstall program., The postinstall invokes project initialization for any consumer declaring this package., Initialization calls the setup materializer at the repository root., The materializer copies package skills into both generic agent and Claude skill directories, installs a Claude hook, and writes a command hook into Claude settings., The setup also changes the repository-local Git hook path and removes exclusions for agent artifacts. - **Evidence against:** No package-controlled network request or credential-exfiltration sink was found in the inspected lifecycle path., The materializer preserves conflicting or edited managed files rather than overwriting them. ## Affected versions and remediation This report applies to @softize/opus@11.1.0. - Avoid installing @softize/opus@11.1.0. 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.
