Those extensions add lifecycle hooks that capture prompts and direct a headless agent to read session transcripts. - **Trigger:** npm installation, then Claude session lifecycle events - **Impact:** Unconsented broad AI-agent control-surface mutation; user prompts and transcripts are persisted/read within projects. - **Evidence paths:** package.json, bin/install.js, hooks/hooks.json, hooks/autosave.sh, hooks/session-end.sh - **Review source:** ai\_review - **Reviewed:** 2026-08-17T20:32:17.713Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** postinstall global AI-agent configuration and hook deployment - **Attack narrative:** Installing the npm package automatically runs an installer that writes plugin, skills, commands, and registration JSON into global Claude and .agents control surfaces. The deployed hooks then execute on session lifecycle events: prompt submission appends user prompt content to a project buffer, and session end invokes Claude headlessly with a path to the session transcript. This is an unconsented postinstall mutation of broad/foreign agent surfaces, even though no network exfiltration is present in the inspected source. - **Rationale:** The package's automatic postinstall installs behavior-bearing hooks and skills into global Claude and .agents locations, not merely its own package directory. This meets the blocking policy for unconsented postinstall mutation of a foreign/broad AI-agent control surface. - **Files touched:** ~/.claude/plugins/marketplaces/arpon007/, ~/.claude/skills/\, ~/.agents/skills/\, ~/.claude/commands/\.md, ~/.claude/plugins/known\_marketplaces.json, ~/.claude/plugins/installed\_plugins.json, \/.decision/.buffers/\.raw ### Review decision - **Verdict:** Malicious - **Confidence:** 96.0% - **Recommended action:** publish\_block - **Intent class:** Malware - **False-positive risk:** Low - **Evidence for:** postinstall automatically launches the installer., Installer writes skills into global Claude and .agents directories, deleting existing same-named directories first., Installer deploys hook-bearing plugin files and registers a marketplace/plugin globally., Installed hooks run on prompt submission and append extracted prompt text to project files., Session-end hook passes a discovered Claude transcript path to headless claude. - **Evidence against:** No network client, download, eval, or child-process API is present in the JavaScript installer., The packaged skill instructs redaction of secrets and PII from decision records. ## Public findings ### 1.
