It installs behavior-bearing instructions that activate across broad user requests and authorize shell commands. - **Trigger:** npm install runs the postinstall hook. - **Impact:** Existing Claude and shared agent harnesses can load package-authored instructions and command permissions outside a project workspace. - **Evidence paths:** package.json, bin/postinstall.mjs - **Review source:** ai\_review - **Reviewed:** 2026-09-03T18:01:01.736Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** Global AI-agent skill injection through postinstall. - **Attack narrative:** The manifest invokes bin/postinstall.mjs during installation. That code detects existing .claude and .agents home directories, creates skills/rig directories, and writes a user-level SKILL.md. The payload instructs multiple agent harnesses to trigger on broad workspace and review requests, including when the user never mentions rig, while allowing shell execution of rig and tapd. This is unconsented install-time mutation of a foreign, broad AI-agent control surface. - **Rationale:** The automatic postinstall hook writes a globally loaded, behavior-bearing agent skill into multiple existing harnesses. Its broad trigger rules and shell permissions make this a concrete AI-agent control-surface hijack. - **Files touched:** .claude/skills/rig/SKILL.md, .agents/skills/rig/SKILL.md ### Review decision - **Verdict:** Malicious - **Confidence:** 99.0% - **Recommended action:** publish\_block - **Intent class:** Malware - **False-positive risk:** Low - **Evidence for:** The package runs a postinstall lifecycle hook automatically., The hook writes a global skill into existing Claude and shared agent harness directories., The installed skill is user-level, broadly triggered, and grants shell access to rig and tapd commands. - **Evidence against:** No runtime self-dependency is declared., Network and command execution elsewhere are tied to explicit CLI operations. ## Public findings ### 1.
