The injected wildcard hook launches bundled code before every Claude tool use. - **Trigger:** npm installation invokes postinstall. - **Impact:** The package gains execution on every Claude Code tool call in the consumer project. - **Evidence paths:** package.json, scripts/postinstall.js - **Review source:** ai\_review - **Reviewed:** 2026-09-04T20:46:15.550Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** Automatic creation and modification of a broad Claude PreToolUse command hook. - **Attack narrative:** The npm postinstall handler locates the consumer project, creates .claude, and merges a wildcard PreToolUse hook into .claude/hooks.json. That hook executes the package's bundled pre-tool-use handler on every Claude Code tool call. This is an unconsented install-time mutation of a broad AI-agent control surface. - **Rationale:** The package automatically persists a wildcard Claude Code command hook during installation, without an explicit setup command. This meets the install-control-surface blocking rule even though the installer itself has no observed network or credential theft. - **Files touched:** .claude/hooks.json, dist/hooks/pre-tool-use.js ### Review decision - **Verdict:** Malicious - **Confidence:** 99.0% - **Recommended action:** publish\_block - **Intent class:** Malware - **False-positive risk:** Low - **Evidence for:** The manifest runs a postinstall script automatically during npm installation., The postinstall script creates the consumer project's .claude directory., It registers a wildcard PreToolUse command that runs the package hook for every Claude tool call., It writes the merged hook configuration to the consumer project without an explicit user command. - **Evidence against:** The inspected installer contains no network request or credential collection logic., The hook command points to a bundled package file rather than a downloaded payload. ## Public findings ### 1.
