An explicit gm-plugkit bootstrap installs or refreshes agent skills, edits project agent instruction files, downloads a native runner, and starts a spool daemon. This is a first-party agent-extension control surface, not install-time execution. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Verdict:** Suspicious - **Confidence:** 93.0% - **Started:** 2026-08-09T08:12:09.872Z - **Finished:** 2026-08-09T08:12:59.242Z - **Download time:** 502 ms - **Static scan time:** 184 ms - **AI review time:** 48683 ms - **Total time:** 49370 ms ## Security analysis ### Published attack-surface review - **Summary:** An explicit gm-plugkit bootstrap installs or refreshes agent skills, edits project agent instruction files, downloads a native runner, and starts a spool daemon. This is a first-party agent-extension control surface, not install-time execution. - **Trigger:** User runs the gm-plugkit CLI or calls ensureReady. - **Impact:** Can persist vendor-controlled instructions in user agent skill directories and project AI-agent configuration, then execute a downloaded daemon. - **Evidence paths:** package.json, bootstrap.js, bootstrap-shared.js, cli.js, SKILL.md - **Review source:** ai\_review - **Reviewed:** 2026-08-09T08:12:59.242Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** Remote skill/native-runner bootstrap plus agent configuration mutation - **Rationale:** This is a concrete, user-triggered first-party AI-agent extension bootstrap with broad instruction/config mutation and remote executable loading. It does not meet the policy threshold for malicious blocking because it is not an unconsented install-time mutation. - **Files touched:** ~/.agents/skills/\/SKILL.md, ~/.claude/skills/\/SKILL.md, \/CLAUDE.md, \/AGENTS.md, \/.gm/, ~/.gm-tools/agentplug-runner - **Network endpoints:** https://api.github.com/repos/AnEntrypoint/agentplug-bin/releases/latest, https://github.com/AnEntrypoint/agentplug-bin/releases/download/${tag}, https://raw.githubusercontent.com/AnEntrypoint/gm/main/skills/${skillName}/SKILL.md, https://registry.npmjs.org/gm-plugkit/latest ### Review decision - **Verdict:** Suspicious - **Confidence:** 93.0% - **Recommended action:** downgrade\_to\_warn - **Intent class:** Dangerous Capability - **False-positive risk:** Low - **Evidence for:** bootstrap.js refreshes skills into ~/.agents and ~/.claude., bootstrap-shared.js alters project CLAUDE.md and AGENTS.md., bootstrap.js fetches remote skills and native runner, then starts a daemon., SKILL.md contains imperative agent-control instructions. - **Evidence against:** package.json has no lifecycle scripts., Activation is through the explicit CLI/import bootstrap path., WASM and runner downloads are SHA-256 checked., No credential harvesting or exfiltration found. ## Public findings ### 1.
