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:** 0.3.479 - **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. Source establishes tool-invoked agent control-surface mutation, which the supplied policy treats as a warning. No block-eligible malicious chain was established; heavy entrypoint obfuscation limits broader assurance. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Recorded final verdict:** Suspicious - **Recorded analysis confidence:** 86.0% - **Started:** 2026-09-30T16:28:11.614Z - **Finished:** 2026-09-30T16:31:03.656Z - **Download time:** 1271 ms - **Static scan time:** 1502 ms - **AI review time:** 169269 ms - **Total time:** 172042 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 MCP server exposes tools that install skills and modify agent MCP configuration. These capabilities warrant a warning, but no confirmed malicious attack was established. - **Trigger:** An MCP client invokes the skill installation or MCP registration tool. - **Impact:** Invoked tools can change agent instructions and registered executable commands. - **Evidence paths:** dist/mcp.cjs - **Review source:** ai\_review - **Reviewed:** 2026-09-30T16:31:03.656Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** Tool arguments select skill scope or MCP command settings; handlers write skill files or update agent configuration. - **Rationale:** Source establishes tool-invoked agent control-surface mutation, which the supplied policy treats as a warning. No block-eligible malicious chain was established; heavy entrypoint obfuscation limits broader assurance. - **Files touched:** config.toml, .claude.json, opencode.json ### Review decision - **Verdict:** Suspicious - **Confidence:** 86.0% - **Recommended action:** downgrade\_to\_warn - **Intent class:** Dangerous Capability - **False-positive risk:** Medium - **Evidence for warning:** The manifest exposes a CLI and contains no install lifecycle hooks or runtime self-dependency., The MCP request handler dispatches caller-selected tools and arguments., The MCP management tool accepts command, arguments, and environment settings and registers them in agent configuration., The Codex configuration writer updates config.toml., The skill management tool installs downloaded files into selectable scopes, including the user's platform skills directory. - **Evidence against:** The inspected configuration mutations are tool-invoked rather than npm-install-triggered., No concrete covert credential export or malicious payload execution was established. ## Affected versions and remediation This report applies to @whalent/agent-core@0.3.479. - Review the evidence and your use of @whalent/agent-core@0.3.479 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.
