It installs skills and registers executable PreToolUse command hooks in the user's global Claude settings. - **Trigger:** npm install, through the postinstall lifecycle hook. - **Impact:** Future Claude Bash tool calls can invoke package-provided hooks without the user's explicit setup action. - **Evidence paths:** package.json, scripts/postinstall.cjs, hooks/winappdriver-session-guard.sh, skills/self-repair/SKILL.md, scripts/install-oracle-client.cjs - **Review source:** ai\_review - **Reviewed:** 2026-09-04T07:28:22.629Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** Automatic global AI-agent skill and command-hook installation. - **Attack narrative:** The package's automatic postinstall runs without a user command for Claude setup. It copies skills to project and home Claude directories, copies executable hooks to the home Claude hooks directory, and registers them as PreToolUse Bash commands in the user's Claude settings. One hook parses each Bash tool command. The package also installs a skill that dictates an AI response banner and downloads a current Oracle archive into the consumer project on Windows. This is unconsented install-time mutation of a broad foreign AI-agent control surface. - **Rationale:** The lifecycle hook automatically persists package-controlled skills and executable command hooks into the user's global Claude configuration. That concrete install-time agent-control mutation meets the blocking policy regardless of the hooks' presently limited warning behavior. - **Files touched:** .claude/skills, ~/.claude/skills, ~/.claude/hooks, ~/.claude/settings.json, oracle/instantclient - **Network endpoints:** https://www.oracle.com/database/technologies/instant-client/winx64-64-downloads.html ### Review decision - **Verdict:** Malicious - **Confidence:** 98.0% - **Recommended action:** publish\_block - **Intent class:** Malware - **False-positive risk:** Low - **Evidence for:** The package runs a postinstall script automatically., The postinstall copies package content into both project and home Claude skill directories, then adds command hooks to the user's Claude settings., Installed PreToolUse hooks inspect Bash tool commands, creating an automatic agent control surface., A bundled skill directs an AI's first reply to use a prescribed activation banner., On Windows, postinstall also fetches and extracts a remotely selected Oracle archive into the consumer project. - **Evidence against:** The inspected hooks only warn about test setup and commit-message format; no credential collection was found., The desktop test configuration binds its Appium service to localhost. ## Public findings ### 1.
