This remains warn-only unless evidence shows foreign-agent hijack through preinstall/install/postinstall, hidden persistence, exfiltration, remote code execution, or other concrete malicious behavior. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Verdict:** Suspicious - **Confidence:** 96.0% - **Started:** 2026-08-09T13:33:35.684Z - **Finished:** 2026-08-09T13:34:12.490Z - **Download time:** 505 ms - **Static scan time:** 167 ms - **AI review time:** 36133 ms - **Total time:** 36806 ms ## Security analysis ### Published attack-surface review - **Summary:** Running the CLI provisions remote agent skills, rewrites project AI-agent instruction wiring, downloads a native runner, and launches it as a detached daemon. No install-time trigger exists. - **Trigger:** User invokes gm-plugkit CLI or bootstrap entrypoint. - **Impact:** Modifies broad AI-agent control surfaces and executes a remotely supplied native binary. - **Evidence paths:** package.json, bootstrap.js, bootstrap-shared.js, cli.js - **Review source:** ai\_review - **Reviewed:** 2026-08-09T13:34:12.490Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** remote agent-skill provisioning and downloaded native daemon execution - **Rationale:** This is a concrete, user-triggered AI-agent control-surface mutation and remote native-code execution chain. It is not an unconsented npm lifecycle attack, so policy calls for warning rather than blocking. - **Files touched:** ~/.agents/skills/\/SKILL.md, ~/.claude/skills/\/SKILL.md, ~/.gm-tools/agentplug-runner, \/.gm/next-step.md, \/CLAUDE.md, \/AGENTS.md - **Network endpoints:** https://api.github.com/repos/AnEntrypoint/agentplug-bin/releases/latest, https://github.com/AnEntrypoint/agentplug-bin/releases/download/${tag}, https://api.github.com/repos/AnEntrypoint/plugkit-bin/releases?per\_page=50, https://raw.githubusercontent.com/AnEntrypoint/gm/main/skills/${skillName}/SKILL.md ### Review decision - **Verdict:** Suspicious - **Confidence:** 96.0% - **Recommended action:** downgrade\_to\_warn - **Intent class:** Dangerous Capability - **False-positive risk:** Low - **Evidence for:** bootstrap.js refreshes remote SKILL.md files into ~/.agents and ~/.claude., bootstrap-shared.js rewrites project CLAUDE.md and AGENTS.md to load .gm instructions., bootstrap.js downloads and executes agentplug-runner from GitHub releases., Remote binary/SKILL hashes lack a package-pinned trust anchor. - **Evidence against:** package.json contains no preinstall, install, or postinstall hook., Network/download behavior is reached through the user-invoked CLI/bootstrap path., No credential harvesting or unrelated-data exfiltration found. ## Public findings ### 1.
