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:** 0.5.8 - **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. Automatic postinstall agent-skill mutation and environment-configurable authenticated remote skill retrieval create a concrete guarded extension risk. The inspected code does not show a completed malicious payload or broad unnamespaced control-surface mutation. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Recorded final verdict:** Suspicious - **Recorded analysis confidence:** 90.0% - **Started:** 2026-09-29T14:53:57.270Z - **Finished:** 2026-09-29T14:55:23.570Z - **Download time:** 1015 ms - **Static scan time:** 852 ms - **AI review time:** 84432 ms - **Total time:** 86300 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:** Installation automatically modifies the consumer agent-skill surface. With configured MCP variables, it retrieves and installs remote skills and forwards an access token to the configured endpoint. - **Trigger:** npm postinstall during package installation, with MCP synchronization additionally requiring configured endpoint and token variables. - **Impact:** This is a guarded first-party agent-extension lifecycle risk; no confirmed malicious attack was established, but remote skill content can affect later agent behavior. - **Evidence paths:** package.json, cli/postinstall.mjs, cli/install-agent-skills.mjs, cli/install-mcp-skills.mjs, cli/mcp-platform-skills.mjs - **Review source:** ai\_review - **Reviewed:** 2026-09-29T14:55:23.570Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** The installer writes namespaced skills under .agents and posts MCP requests using an environment-selected HTTP(S) URL and bearer token. - **Rationale:** Automatic postinstall agent-skill mutation and environment-configurable authenticated remote skill retrieval create a concrete guarded extension risk. The inspected code does not show a completed malicious payload or broad unnamespaced control-surface mutation. - **Files touched:** .agents/skills/command-center, .agents/skills/mainsequence ### Review decision - **Verdict:** Suspicious - **Confidence:** 90.0% - **Recommended action:** downgrade\_to\_warn - **Intent class:** Dangerous Capability - **False-positive risk:** Low - **Evidence for warning:** The package declares an automatic postinstall entrypoint., Postinstall installs package-provided agent skills into the consumer repository., The installer targets a namespaced .agents skills directory., When MCP configuration is available, postinstall fetches a remote skill catalog., MCP URL selection accepts environment-provided HTTP(S) endpoints., MCP requests send the configured access token as a bearer credential. - **Evidence against:** The remote synchronization path is skipped when MCP configuration is absent., The observed destinations are namespaced skill directories, not arbitrary project paths., No self-dependency or arbitrary code execution sink was found in the inspected paths. ## Affected versions and remediation This report applies to @dev-mainsequence/command-center-sdk@0.5.8. - Review the evidence and your use of @dev-mainsequence/command-center-sdk@0.5.8 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.
