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:** 0.3.9 - **Selected version is latest:** Yes - **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 postinstall hook automatically invokes the package CLI to install bundled skills into supported agent skill directories. This is first-party package-owned agent extension setup. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Recorded final verdict:** Suspicious - **Recorded analysis confidence:** 84.0% - **Started:** 2026-10-07T23:57:32.073Z - **Finished:** 2026-10-07T23:57:50.691Z - **Download time:** 2057 ms - **Static scan time:** 118 ms - **AI review time:** 16442 ms - **Total time:** 18618 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 postinstall hook automatically invokes the package CLI to install bundled skills into supported agent skill directories. This is first-party package-owned agent extension setup. - **Trigger:** Installing the package with lifecycle scripts enabled, unless NANOCORP\_NO\_AGENT\_SKILLS is set. - **Impact:** Agent skill directories may be modified automatically. No further attack behavior was established from the readable source. - **Evidence paths:** package.json, scripts/postinstall.js, bin/nanocorp.js - **Review source:** ai\_review - **Reviewed:** 2026-10-07T23:57:50.691Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** The hook starts the CLI with the skills install command; the CLI launcher selects and executes a vendored platform binary. - **Rationale:** The automatic lifecycle hook mutates agent skill directories through the package’s own skills installer, which warrants a warning under the agent extension lifecycle policy. The available source does not establish a concrete malicious chain. - **Files touched:** Supported agent skill directories ### Review decision - **Verdict:** Suspicious - **Confidence:** 84.0% - **Recommended action:** downgrade\_to\_warn - **Intent class:** Dangerous Capability - **False-positive risk:** Medium - **Evidence for warning:** The package defines an automatic postinstall hook., The hook runs the package’s own CLI to install bundled agent skills unless an opt-out variable is set., The CLI selects and runs a vendored platform executable; its behavior was not readable during source inspection. - **Evidence against:** The hook is limited to NanoCorp’s own skills installation and suppresses CLI output., The launcher passes through caller arguments and inherits standard I/O. ## Affected versions and remediation This report applies to nanocorp@0.3.9. - Review the evidence and your use of nanocorp@0.3.9 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.
