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:** 0.6.16 - **Selected version is latest:** Yes - **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 source shows a first-party agent capture integration that modifies project-level agent configuration when set up through the CLI. The reviewed evidence does not establish an npm install trigger or a concrete malicious chain, so this is a warning-level capability. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Recorded final verdict:** Suspicious - **Recorded analysis confidence:** 82.0% - **Started:** 2026-10-12T09:46:54.205Z - **Finished:** 2026-10-12T09:48:15.419Z - **Download time:** 513 ms - **Static scan time:** 3126 ms - **AI review time:** 77574 ms - **Total time:** 81214 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:** The package provides a first-party integration that captures coding-agent session activity through local hooks and a plugin. The inspected evidence supports a guarded integration capability, not a confirmed attack. - **Trigger:** The user invokes the CLI’s agent connection or setup flow. - **Impact:** Agent session content can be captured into M9R’s local memory and may be handled by the product’s runtime. - **Evidence paths:** dist/cross-agent-capture-setup-core.js - **Review source:** ai\_review - **Reviewed:** 2026-10-12T09:48:15.419Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** Setup adds project-local agent hooks or a plugin that records session activity for M9R. - **Rationale:** The source shows a first-party agent capture integration that modifies project-level agent configuration when set up through the CLI. The reviewed evidence does not establish an npm install trigger or a concrete malicious chain, so this is a warning-level capability. - **Files touched:** dist/cross-agent-capture-setup-core.js ### Review decision - **Verdict:** Suspicious - **Confidence:** 82.0% - **Recommended action:** downgrade\_to\_warn - **Intent class:** Dangerous Capability - **False-positive risk:** Medium - **Evidence for warning:** The package exposes \`m9r\` and \`oathlock\` CLI entrypoints, with no install lifecycle hook in its manifest., The setup code adds a project-local SessionEnd hook for Claude Code and Codex while preserving existing hook groups., The generated OpenCode plugin captures session activity into M9R’s local memory; this is a first-party agent integration capability. - **Evidence against:** The reviewed setup behavior is tied to CLI setup and project-local agent configuration, not an npm install hook., The Codex hook is written for a separate in-product trust review before it runs. ## Affected versions and remediation This report applies to m9r-cli@0.6.16. - Review the evidence and your use of m9r-cli@0.6.16 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.
