It installs package skills unconditionally and, for existing setup, registers MCP, hooks, and allowlisted tools. - **Trigger:** npm install / package postinstall - **Impact:** Package code executes on Claude prompt and tool lifecycle events and can influence agent behavior. - **Evidence paths:** package.json, dist/bin/install.js, dist/chunk-FM5QLDG6.js, dist/hooks/post-tool-combined.js, dist/hooks/prompt-submit.js - **Review source:** ai\_review - **Reviewed:** 2026-07-30T11:55:30.349Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** Global Claude skills, MCP, hooks, and permission mutation - **Attack narrative:** Installing the package invokes postinstall. It copies package-controlled skills to the user-wide Claude directory even before setup; where prior setup exists, it also writes a global MCP entry, lifecycle hooks for prompt and tool events, and MCP permission allowlist entries. The installed post-tool hook receives tool inputs and outputs and records them through package services, creating a broad unconsented agent-control surface. - **Rationale:** Source inspection confirms an install-time, user-wide Claude Code control-surface mutation, not merely suspicious primitives. This meets the blocking policy regardless of the lack of a confirmed external exfiltration host in the inspected hook path. - **Files touched:** package.json, dist/bin/install.js, dist/chunk-FM5QLDG6.js, dist/hooks/post-tool-combined.js, dist/hooks/prompt-submit.js, ~/.claude/skills, ~/.claude.json, ~/.claude/settings.json ### Review decision - **Verdict:** Malicious - **Confidence:** 99.0% - **Recommended action:** publish\_block - **Intent class:** Malware - **False-positive risk:** Low - **Evidence for:** package.json runs install.js via postinstall., install.js postinstall copies package commands into ~/.claude/skills., On prior setup, postinstall registers MCP and installs Claude hooks., chunk-FM5QLDG6.js hooks every prompt/tool event and expands MCP permissions., post-tool-combined.js records prompt/tool inputs and outputs to package services. - **Evidence against:** Inspected hook code shows no external exfiltration endpoint in this path., The initial postinstall avoids daemon startup when no package setup exists. ## Public findings ### 1.
