The new wildcard hook executes this package’s handler before every Claude tool call. - **Trigger:** npm install runs postinstall. - **Impact:** The package gains automatic execution in a foreign AI-agent control surface for all tool calls. - **Evidence paths:** package.json, scripts/postinstall.js - **Review source:** ai\_review - **Reviewed:** 2026-09-04T20:46:14.536Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** Automatic creation and modification of a broad Claude Code PreToolUse hook. - **Attack narrative:** The manifest automatically launches scripts/postinstall.js during installation. That script locates the consumer project, creates .claude if needed, and writes a wildcard PreToolUse command into .claude/hooks.json. The command points to the package’s pre-tool-use handler, causing it to run for every subsequent Claude Code tool call without an explicit setup command from the user. - **Rationale:** This is an unconsented postinstall mutation of a foreign, broad AI-agent control surface. The wildcard command is automatically activated for every Claude tool call, satisfying the install-hook abuse blocking policy. - **Files touched:** .claude/hooks.json, dist/hooks/pre-tool-use.js ### 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 installer finds the consumer project and creates a .claude directory there., It registers a wildcard Claude PreToolUse command that runs the package handler for every tool call. - **Evidence against:** No runtime dependency on this package’s own name appears in the top-level manifest., The install script merges rather than overwrites the existing hooks configuration. ## Public findings ### 1.
