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:** 0.3.512 - **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 has no install hook, and the inspected skill setup is an explicit runtime capability. Because it can place fetched content in agent skill directories, residual agent extension setup risk warrants a warning rather than a block. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Recorded final verdict:** Suspicious - **Recorded analysis confidence:** 78.0% - **Started:** 2026-10-16T06:32:42.942Z - **Finished:** 2026-10-16T06:34:31.763Z - **Download time:** 1283 ms - **Static scan time:** 1459 ms - **AI review time:** 106078 ms - **Total time:** 108821 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 skill setup path that fetches named skill files from its service and writes them into agent skill directories. This creates a conditional agent configuration risk when that setup operation is invoked. - **Trigger:** An agent runtime invokes the skill installation operation. - **Impact:** Installed skill content can affect the instructions available to the selected agent; no automatic attack was established. - **Evidence paths:** dist/mcp.cjs, dist/index.cjs - **Review source:** ai\_review - **Reviewed:** 2026-10-16T06:34:31.763Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** The package fetches files for a supplied skill identifier, then creates a machine, workspace, or agent skill directory and writes those files there. - **Rationale:** The package has no install hook, and the inspected skill setup is an explicit runtime capability. Because it can place fetched content in agent skill directories, residual agent extension setup risk warrants a warning rather than a block. - **Files touched:** dist/mcp.cjs, ~/.claude/skills/\ - **Network endpoints:** memory.whalent.com ### Review decision - **Verdict:** Suspicious - **Confidence:** 78.0% - **Recommended action:** downgrade\_to\_warn - **Intent class:** Dangerous Capability - **False-positive risk:** Medium - **Evidence for warning:** The manifest declares the runtime entry point and no install lifecycle hook., The MCP source maps agent skills to platform directories and supports machine, workspace, and agent scopes., The installer creates the selected skill directory and writes supplied files there., The skill downloader requests files from the Whalent service using an authorization header. - **Evidence against:** The observed skill setup is an explicit runtime operation, not an npm install hook., The inspected source establishes no credential theft, destructive action, or remote code execution. ## Affected versions and remediation This report applies to @whalent/agent-core@0.3.512. - Review the evidence and your use of @whalent/agent-core@0.3.512 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.
