It installs skills and a Stop hook that executes the package CLI when an agent turn ends. - **Trigger:** npm install of @softize/opus - **Impact:** Unconsented persistence and execution in the consumer's AI-agent environment. - **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:** 2026-08-13T00:48:58.522Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** automatic materialization of agent skills, instructions, and Claude hook configuration - **Attack narrative:** Installing the package automatically invokes initProject in the consuming project. That setup writes broad .agents and .claude content, modifies AGENTS.md and CLAUDE.md, configures a Claude Stop hook, and installs a hook that invokes the Opus CLI after agent turns. These changes occur without an explicit user setup command, creating an unconsented AI-agent control surface. - **Rationale:** The package has concrete postinstall mutation of foreign, broad AI-agent control surfaces, including a command-executing Claude hook. This meets the install-control-surface block boundary even though no exfiltration was found. - **Files touched:** package.json, bin/lib/postinstall.mjs, bin/lib/init.mjs, bin/lib/materialize.mjs, .agents/skills/\*\*, .claude/skills/\*\*, .claude/hooks/opus-check-on-stop.mjs, .claude/settings.json, AGENTS.md, CLAUDE.md, .githooks/\*\*, base.json, opus.json ### Review decision - **Verdict:** Malicious - **Confidence:** 98.0% - **Recommended action:** publish\_block - **Intent class:** Malware - **False-positive risk:** Low - **Evidence for:** package.json runs postinstall automatically., Postinstall invokes project initialization for the consumer directory., Initialization invokes setup materialization., Materialization deploys skills and hooks into .agents and .claude., Setup writes a Claude Stop hook that runs package code on agent turn completion. - **Evidence against:** No source evidence of credential harvesting, exfiltration, or remote payload retrieval., The markdown new Function use is limited to project-trusted documentation previews. ## Public findings ### 1.
