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:** 9.5.0 - **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 package automatically configures a first-party statusline in global Claude settings, so a lifecycle-related agent extension warning is warranted. The inspected evidence does not establish malicious behavior, while an unresolved executable helper prevents a clean assurance. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Recorded final verdict:** Suspicious - **Recorded analysis confidence:** 84.0% - **Started:** 2026-10-18T23:38:33.477Z - **Finished:** 2026-10-18T23:40:25.238Z - **Download time:** 1533 ms - **Static scan time:** 2063 ms - **AI review time:** 108163 ms - **Total time:** 111761 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 npm postinstall configures a package-owned Claude statusline in the user's global settings, creating a recurring agent extension. A separate shared executable artifact could not be resolved by offline analysis. - **Trigger:** Installing the package with npm triggers its postinstall script. - **Impact:** The global setting causes package code to run in Claude's statusline lifecycle. The unresolved shared helper prevents full behavioral assurance, but the inspected evidence does not establish a concrete attack. - **Evidence paths:** package.json, src/scripts/global-install.js, src/utils/hooks-installer.js, framework/hooks/claude-code/statusline.py, framework/hooks/shared/e2e-check.js, .lpm-inspection-5uD18E/0-ff88b4a07a6e.txt - **Review source:** ai\_review - **Reviewed:** 2026-10-18T23:40:25.238Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** The hook copies statusline scripts into the user's Claude directory and sets a global statusline command. On Windows, selecting the command may attempt to install Python if it is missing. - **Rationale:** The package automatically configures a first-party statusline in global Claude settings, so a lifecycle-related agent extension warning is warranted. The inspected evidence does not establish malicious behavior, while an unresolved executable helper prevents a clean assurance. - **Files touched:** ~/.claude/settings.json, package.json, src/scripts/global-install.js, src/utils/hooks-installer.js, framework/hooks/claude-code/statusline.py ### Review decision - **Verdict:** Suspicious - **Confidence:** 84.0% - **Recommended action:** downgrade\_to\_warn - **Intent class:** Dangerous Capability - **False-positive risk:** Medium - **Evidence for warning:** The package's postinstall launches global-install.js, which calls the global statusline installer automatically., That installer copies package scripts into the user's Claude directory and merges a command into global Claude settings; on Windows, selecting that command may attempt to install Python if it is missing., A Claude telemetry hook imports the shared e2e helper, whose offline analysis identifies it as an unrecognized executable artifact and leaves its behavior unresolved., The other inspected agent-integration locations concern a plugin check, project-local settings and MCP bookkeeping, worktree operations, or an explicit plugin command. - **Evidence against:** The statusline reads Claude-provided JSON and derives the workspace directory for display., The plugin installer is exposed as a CLI command that requires a plugin name. ## Affected versions and remediation This report applies to @polymorphism-tech/morph-spec@9.5.0. - Review the evidence and your use of @polymorphism-tech/morph-spec@9.5.0 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.
