The CLI is designed to register skills into AI-agent skill locations, including .agents/skills. - **Trigger:** npm postinstall during package installation - **Impact:** The install changes AI-agent control surfaces without a user command or confirmation. - **Evidence paths:** package.json, scripts/postinstall.cjs, dist/index.js - **Review source:** ai\_review - **Reviewed:** 2026-09-08T14:34:49.814Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** automatic quiet AI-agent skill registration - **Attack narrative:** An npm postinstall hook invokes the bundled CLI with /init and --quiet. The shipped, obfuscated CLI contains targets for .agents/skills and other encoded skill locations, so installation can alter agent behavior before the user explicitly runs the CLI. This is an unconsented install-time mutation of a broad AI-agent control surface. - **Rationale:** The automatic lifecycle hook and CLI initialization form a concrete unconsented agent-control-surface mutation chain. Obfuscation makes the additional target locations less transparent. - **Files touched:** package.json, scripts/postinstall.cjs, dist/index.js ### Review decision - **Verdict:** Malicious - **Confidence:** 98.0% - **Recommended action:** publish\_block - **Intent class:** Malware - **False-positive risk:** Low - **Evidence for block:** The package runs a postinstall lifecycle hook automatically., That hook launches the packaged CLI with /init and --quiet during installation., The obfuscated CLI defines skill targets including the broad .agents/skills location and additional encoded platform locations., The install path mutates AI-agent skill directories without an explicit user command. - **Evidence against:** No self-dependency was declared., No credential exfiltration endpoint was confirmed from the inspected install hook. ## Affected versions and remediation This report applies to sino-bc-cli@1.8.3. - Avoid installing sino-bc-cli@1.8.3. 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.
