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:** 0.15.0 - **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 postinstall hook automatically installs this package’s agent materials into a consuming project, which warrants a lifecycle warning. The inspected source does not show exfiltration, remote execution, or another concrete attack chain. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Recorded final verdict:** Suspicious - **Recorded analysis confidence:** 91.0% - **Started:** 2026-10-07T06:52:53.202Z - **Finished:** 2026-10-07T06:53:18.441Z - **Download time:** 773 ms - **Static scan time:** 201 ms - **AI review time:** 24263 ms - **Total time:** 25239 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:** Postinstall automatically links this package’s agent files into a consuming project. This is a real agent extension lifecycle risk, but the inspected source does not establish a concrete malicious attack. - **Trigger:** Installing the package in a consuming project where its package directory exists under node\_modules. - **Impact:** The package’s agent materials become available to the consuming project without a separate link command; the inspected behavior supports a warning, not a confirmed attack. - **Evidence paths:** package.json, bin/cli.js - **Review source:** ai\_review - **Reviewed:** 2026-10-07T06:53:18.441Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** The postinstall handler calls the CLI link routine, which creates package file links under the consumer’s .agents directory. - **Rationale:** The postinstall hook automatically installs this package’s agent materials into a consuming project, which warrants a lifecycle warning. The inspected source does not show exfiltration, remote execution, or another concrete attack chain. - **Files touched:** .agents ### Review decision - **Verdict:** Suspicious - **Confidence:** 91.0% - **Recommended action:** downgrade\_to\_warn - **Intent class:** Dangerous Capability - **False-positive risk:** Medium - **Evidence for warning:** The package runs a postinstall command that invokes its CLI., Postinstall targets the consuming project and automatically links the package when it is installed there., The CLI links package-owned agent files into the consumer’s .agents directory; this is first-party agent setup and merits a warning., The flagged graph renderer runs Graphviz with supplied diagram input when invoked., The brainstorming server binds to a configurable host and port when started directly., The web UI validator dynamically imports a package-local token module as part of validation. - **Evidence against:** The postinstall path is an agent setup operation; the inspected code does not show credential collection, remote payload execution, or outbound network transmission., The flagged dynamic import and child-process use occur in validation or rendering tools, not in the postinstall path. The server starts only when run as the main module. ## Affected versions and remediation This report applies to @abblor/agent-os@0.15.0. - Review the evidence and your use of @abblor/agent-os@0.15.0 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.
