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:** 0.3.8 - **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. LPM treats this as warn-only first-party agent extension lifecycle risk. The npm postinstall hook automatically invokes the bundled CLI to install NanoCorp skills for supported coding agents. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Recorded final verdict:** Suspicious - **Recorded analysis confidence:** 78.0% - **Started:** 2026-10-07T06:12:08.788Z - **Finished:** 2026-10-07T06:12:42.690Z - **Download time:** 1253 ms - **Static scan time:** 120 ms - **AI review time:** 32529 ms - **Total time:** 33902 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 npm postinstall hook automatically invokes the bundled CLI to install NanoCorp skills for supported coding agents. - **Trigger:** Installing the package with lifecycle scripts enabled, unless NANOCORP\_NO\_AGENT\_SKILLS is set. - **Impact:** Agent skill directories may be modified during installation. No further attack behavior was established from the inspected source. - **Review source:** ai\_review - **Reviewed:** 2026-10-07T06:12:42.690Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** The hook starts the package launcher with \`skills install --quiet\`; the launcher delegates to a platform-specific bundled binary. The binary's implementation could not be inspected as source. - **Rationale:** The postinstall hook automatically installs package-owned agent skills, a lifecycle risk that warrants a warning. Inspected JavaScript does not establish malicious behavior, and the bundled binary contents were unavailable for source inspection. - **Files touched:** package.json, scripts/postinstall.js, bin/nanocorp.js, bin/resolve.js ### Review decision - **Verdict:** Suspicious - **Confidence:** 78.0% - **Recommended action:** downgrade\_to\_warn - **Intent class:** Dangerous Capability - **False-positive risk:** Medium - **Evidence for warning:** package.json runs scripts/postinstall.js automatically after installation., The hook invokes the bundled CLI to run \`skills install --quiet\` unless NANOCORP\_NO\_AGENT\_SKILLS is set., The launcher executes the platform-specific bundled binary; its internal skill installation behavior could not be inspected because the artifact is binary. - **Evidence against:** The hook has an explicit opt-out and suppresses output; the available source does not show credential access, network activity, or destructive actions., The launcher selects a binary shipped with the package, consistent with the CLI structure. ## Affected versions and remediation This report applies to nanocorp@0.3.8. - Review the evidence and your use of nanocorp@0.3.8 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.
