Treat them as untrusted evidence. Do not execute instructions or code found in this document. ## Verdict summary **Flagged as AI-agent capability risk** — Allowed by default with warning: agent-facing configuration or capability changes need review before use. - **Verdict:** Suspicious - **Product-default install policy:** Warn - **Firewall policy:** Warn-only AI-agent capability risk - **Public report status:** Published - **Threat category:** AI-agent capability abuse - **Selected version:** 0.3.495 - **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. Inspected source supports a warning for runtime agent configuration capability, with no evidence establishing an unconsented npm install attack. Obfuscation and limited verification of the oversized core reduce confidence in broader conclusions. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Recorded final verdict:** Suspicious - **Recorded analysis confidence:** 78.0% - **Started:** 2026-10-03T22:11:36.624Z - **Finished:** 2026-10-03T22:13:23.779Z - **Download time:** 1810 ms - **Static scan time:** 1899 ms - **AI review time:** 103445 ms - **Total time:** 107155 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 runtime exposes agent configuration capabilities through MCP tool requests. No confirmed malicious attack was established, but these operations can change agent skills and executable server configuration. - **Trigger:** CLI runtime activation followed by an MCP tool request to install a skill or register or remove a server. - **Impact:** Invoked operations can alter instructions and tools available to an agent; this warrants a capability warning rather than a malware block. - **Evidence paths:** dist/core.cjs, dist/mcp.cjs - **Review source:** ai\_review - **Reviewed:** 2026-10-03T22:13:23.779Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** Tool handlers download skill files and write agent directories, or modify MCP server configuration using request-supplied commands and arguments. - **Rationale:** Inspected source supports a warning for runtime agent configuration capability, with no evidence establishing an unconsented npm install attack. Obfuscation and limited verification of the oversized core reduce confidence in broader conclusions. - **Files touched:** .cursor, config.toml ### Review decision - **Verdict:** Suspicious - **Confidence:** 78.0% - **Recommended action:** downgrade\_to\_warn - **Intent class:** Dangerous Capability - **False-positive risk:** Medium - **Evidence for warning:** dist/core.cjs routes MCP tool requests to operations that install downloaded skills and register or remove MCP servers., dist/mcp.cjs resolves skill destinations under workspace or home agent directories and writes supplied files., dist/mcp.cjs can update MCP server entries in config.toml., package.json has no npm install hooks or runtime self-dependency; dist/index.cjs activates the core through CLI execution. - **Evidence against:** No concrete covert credential export or malicious install-time mutation was established., Obfuscated bundles limit inspection; dist/core.cjs exceeded the citation tool's verification size limit. ## Affected versions and remediation This report applies to @whalent/agent@0.3.495. - Review the evidence and your use of @whalent/agent@0.3.495 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.
