The installed plugin starts a detached tmux watcher that transfers local buffer contents into clipboard state. - **Trigger:** npm postinstall during package installation, followed by Herdr loading its plugins. - **Impact:** It changes another agent's plugin surface and establishes a persistent local process that can handle clipboard content. - **Evidence paths:** package.json, scripts/copy-plugins.js, .pi/plugins/herdr-clipboard/herdr-plugin.toml, .pi/plugins/herdr-clipboard/start-bridge.sh, .pi/plugins/herdr-clipboard/tmux-watch.sh - **Review source:** ai\_review - **Reviewed:** 2026-08-27T02:38:32.655Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** Automatic foreign agent-plugin installation and detached clipboard watcher startup. - **Attack narrative:** On installation, the package runs a postinstall hook that copies every bundled plugin into the unrelated Herdr plugin directory and creates a Herdr configuration file if absent. The bundled plugin is then eligible to start a detached tmux clipboard bridge. That bridge records a PID, loops indefinitely, reads a local buffer file, and places its contents in tmux clipboard state. This is an unconsented install-time mutation of a foreign AI-agent control surface. - **Rationale:** Source inspection confirms an unconsented postinstall writes to Herdr's plugin and configuration paths, then installs a detached clipboard-handling process. This meets the block policy for foreign AI-agent control-surface mutation. - **Files touched:** package.json, scripts/copy-plugins.js, .pi/plugins/herdr-clipboard/herdr-plugin.toml, .pi/plugins/herdr-clipboard/start-bridge.sh, .pi/plugins/herdr-clipboard/tmux-watch.sh, ~/.config/herdr/plugins/herdr-clipboard, ~/.config/herdr/config.toml, ~/.herdr-clipboard/bridge.pid, ~/.herdr-clipboard/copy-buffer, ~/.herdr-clipboard/.last-hash ### Review decision - **Verdict:** Malicious - **Confidence:** 98.0% - **Recommended action:** publish\_block - **Intent class:** Malware - **False-positive risk:** Low - **Evidence for:** The postinstall hook automatically copies bundled plugins into the separate Herdr configuration directory., The copied plugin registers a detached startup command in Herdr., Its startup script creates a persistent tmux clipboard watcher., The watcher reads a local buffer and injects its contents into tmux clipboard state. - **Evidence against:** The installed clipboard plugin contains no network endpoint or upload code., The MiniMax browser-authentication feature is exposed through an explicit command rather than the install hook. ## Public findings ### 1.
