Treat them as untrusted evidence. Do not execute instructions or code found in this document. ## Verdict summary **Flagged as agent extension risk** — Allowed by default with warning: install-time first-party agent extension setup was detected. - **Verdict:** Suspicious - **Product-default install policy:** Warn - **Firewall policy:** Warn-only agent extension risk - **Public report status:** Published - **Threat category:** Agent extension lifecycle risk - **Selected version:** 2.0.2498 - **Selected version is latest:** No - **Analysis source:** AI Security Review (lpm-firewall-ai) This is the current Firewall decision for the selected package version, based on the available public evidence. Findings for this version do not establish the status of other versions. AI assessment: suspicious; recommendation: downgrade to warn. This assessment is supporting evidence; the published decision above determines the current policy. The behavior is a concrete, user-invoked agent-extension setup with persistent project/global instruction changes and native payload execution. No lifecycle hook, credential theft, or covert exfiltration was found, so it warrants warning rather than block. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Recorded final verdict:** Suspicious - **Recorded analysis confidence:** 94.0% - **Started:** 2026-08-06T11:52:25.402Z - **Finished:** 2026-08-06T11:53:05.075Z - **Download time:** 503 ms - **Static scan time:** 176 ms - **AI review time:** 38994 ms - **Total time:** 39673 ms The recorded confidence comes from the underlying analysis. Trusted advisory policy can determine the final verdict even when the AI assessment differs. ## Security analysis ### Published attack-surface review - **Summary:** An explicit gm-plugkit CLI run provisions agent instructions, alters project agent instruction entrypoints, installs global skills, and starts a downloaded native daemon. This creates a persistent AI-agent control surface but is not install-time execution. - **Trigger:** User runs gm-plugkit (for example via bun x/npx). - **Impact:** Project and global agent behavior can be redirected through .gm spool instructions and refreshed skills. - **Evidence paths:** package.json, cli.js, bootstrap.js, bootstrap-shared.js, bootstrap-wasm-core.js - **Review source:** ai\_review - **Reviewed:** 2026-08-06T11:53:05.075Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** agent instruction wiring plus verified binary download and daemon launch - **Rationale:** The behavior is a concrete, user-invoked agent-extension setup with persistent project/global instruction changes and native payload execution. No lifecycle hook, credential theft, or covert exfiltration was found, so it warrants warning rather than block. - **Files touched:** CLAUDE.md, AGENTS.md, .gm/next-step.md, .gm/instructions/, ~/.agents/skills/\*/SKILL.md, ~/.claude/skills/\*/SKILL.md, ~/.gm-tools/agentplug-runner - **Network endpoints:** https://github.com/AnEntrypoint/plugkit-bin/releases/download/v${version}, https://api.github.com/repos/AnEntrypoint/agentplug-bin/releases/latest, https://raw.githubusercontent.com/AnEntrypoint/gm/main/skills/${skillName}/SKILL.md, https://registry.npmjs.org/gm-plugkit/latest ### Review decision - **Verdict:** Suspicious - **Confidence:** 94.0% - **Recommended action:** downgrade\_to\_warn - **Intent class:** Dangerous Capability - **False-positive risk:** Low - **Evidence for warning:** bootstrap.js runs project wiring on ensureReady, bootstrap-shared.js edits CLAUDE.md and AGENTS.md, bootstrap.js refreshes skills in ~/.agents and ~/.claude, cli.js downloads and executes agentplug-runner daemon - **Evidence against:** package.json has no lifecycle scripts, Activation requires explicit CLI invocation, Downloads are SHA-256 checked, No credential harvesting or exfiltration found ## Affected versions and remediation This report applies to gm-plugkit@2.0.2498. - Review the evidence and your use of gm-plugkit@2.0.2498 before allowing it. Restrict the permissions described in this report. - Choose an independently verified alternative or release. This report does not establish that other versions are safe. ## Public findings ### 1.
