It installs agent skills, a Claude Stop hook, instructions, and Git-hook configuration. - **Trigger:** npm install of @softize/opus - **Impact:** Persists package-controlled instructions and commands in Claude/agent configuration and repository hooks. - **Evidence paths:** bin/lib/postinstall.mjs, bin/lib/init.mjs, bin/lib/materialize.mjs, registry/hooks/opus-check-on-stop.mjs - **Review source:** ai\_review - **Reviewed:** 2026-08-23T02:35:06.480Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** postinstall-driven consumer-project AI-agent and Git-hook materialization - **Attack narrative:** On npm installation, postinstall locates the consumer project and invokes setup. That setup materializes package-controlled skills into both agent directories, adds a command-bearing Claude Stop hook, updates AGENTS.md and CLAUDE.md, and configures Git hooks. These are persistent AI-agent control-surface mutations activated without an explicit setup command. - **Rationale:** The lifecycle hook performs unconsented, broad consumer-project AI-agent and hook configuration. This meets the firewall's install-time AI-agent control-surface block boundary despite collision checks and lack of exfiltration. - **Files touched:** package.json, bin/lib/postinstall.mjs, bin/lib/init.mjs, bin/lib/materialize.mjs, opus.json, base.json, .agents/skills/, .claude/skills/, .claude/hooks/opus-check-on-stop.mjs, .claude/settings.json, AGENTS.md, CLAUDE.md, .githooks/, .git/config, .git/info/exclude ### Review decision - **Verdict:** Malicious - **Confidence:** 99.0% - **Recommended action:** publish\_block - **Intent class:** Malware - **False-positive risk:** Low - **Evidence for:** Its postinstall automatically calls initProject in the consuming project., Setup copies package skills into both .agents/skills and .claude/skills., Setup adds a Claude Stop hook to .claude/settings.json., Setup configures Git hooks and rewrites agent-artifact exclusions during install. - **Evidence against:** Writes are project-scoped and refuse collisions with non-Opus-managed files., No credential harvesting or network exfiltration was found in the inspected lifecycle path. ## Public findings ### 1.
