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:** 0.9.241 - **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-time hook, and the inspected network and agent-configuration behavior is tied to explicit product setup and organization-managed skills. Automatic session-start updates into agent skill directories leave a real extension lifecycle risk, so warn without treating it as a confirmed attack. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Recorded final verdict:** Suspicious - **Recorded analysis confidence:** 83.0% - **Started:** 2026-10-17T21:21:13.986Z - **Finished:** 2026-10-17T21:22:41.465Z - **Download time:** 780 ms - **Static scan time:** 1850 ms - **AI review time:** 84848 ms - **Total time:** 87479 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 has a conditional agent-extension update surface: onboarding adds a session-start skill-repair hook, and later repairs can place organization-provided instructions in user-level agent skill folders. The inspected source does not establish an attack or automatic invocation of those skills. - **Trigger:** A user runs onboarding; later, a Claude Code session start runs the configured repair hook when the package has a token. - **Impact:** Organization-provided instructions can become discoverable to the agent without a separate per-skill approval; the source does not show the package automatically invoking them. - **Evidence paths:** bin/cortex-mcp.mjs, lib/setup.mjs, lib/editors/claude.mjs, lib/skills.mjs - **Review source:** ai\_review - **Reviewed:** 2026-10-17T21:22:41.465Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** Repair fetches organization skill content from the configured Cortex service and writes it into skill directories for detected agent tools. Changed local content is backed up before replacement. - **Rationale:** The package has no install-time hook, and the inspected network and agent-configuration behavior is tied to explicit product setup and organization-managed skills. Automatic session-start updates into agent skill directories leave a real extension lifecycle risk, so warn without treating it as a confirmed attack. - **Files touched:** ~/.claude/skills/\/SKILL.md, ~/.codex/skills/\/SKILL.md - **Network endpoints:** CORTEX\_URL/api/skills ### Review decision - **Verdict:** Suspicious - **Confidence:** 83.0% - **Recommended action:** downgrade\_to\_warn - **Intent class:** Dangerous Capability - **False-positive risk:** Medium - **Evidence for warning:** package.json exposes a CLI and has no install lifecycle hook; its scripts are release, promote, and rollback., The reviewed Codex, Cursor, and setup locations point to their expected user configuration directories; uninstall targets this package’s entries, and the transcript helper searches for a session-specific local file., Explicit onboarding installs skills and connects organization-skill repair; Claude’s configured session-start hook runs that repair again in later sessions., When a token is available, repair fetches organization skills from the configured Cortex service and writes returned skill content into detected Claude Code and Codex skill directories., This creates a conditional extension-update surface: newly synchronized instructions become discoverable to the agent, but the source does not show that the package automatically invokes each skill., The Antigravity adapter writes a script and launch-agent file but does not load the agent itself. - **Evidence against:** The package has no npm install-time trigger, and the agent setup begins through an explicit CLI onboarding action., Organization-skill synchronization requires an available token and uses the configured Cortex service; no unrelated credential recipient or hidden payload execution was identified., The source does not show synchronized skills being automatically invoked, and Antigravity persistence requires a separate manual activation step. ## Affected versions and remediation This report applies to @theronap/cortex-mcp@0.9.241. - Review the evidence and your use of @theronap/cortex-mcp@0.9.241 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.
