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:** 0.14.1 - **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. The postinstall hook automatically installs a first-party skill into global agent directories, creating a concrete agent-extension lifecycle risk. The inspected skill content is ordinary product guidance and the source shows no separate malicious behavior, so this warrants a warning rather than a block. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Recorded final verdict:** Suspicious - **Recorded analysis confidence:** 91.0% - **Started:** 2026-10-22T14:32:19.595Z - **Finished:** 2026-10-22T14:32:58.748Z - **Download time:** 1773 ms - **Static scan time:** 54 ms - **AI review time:** 37325 ms - **Total time:** 39153 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 install hook automatically places the package’s skill into global AI-agent skill directories. This is first-party agent extension setup with a real install-time configuration effect; no separate attack behavior was identified in the inspected sources. - **Trigger:** Installing the package runs its postinstall script. - **Impact:** The installed skill becomes available to those agents without a separate setup action. The inspected skill provides product workflow guidance. - **Evidence paths:** package.json, scripts/postinstall.js, skills/specsync/SKILL.md - **Review source:** ai\_review - **Reviewed:** 2026-10-22T14:32:58.748Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** The script creates global skill directories and writes the package’s SKILL.md into them for several agents, including Codex. - **Rationale:** The postinstall hook automatically installs a first-party skill into global agent directories, creating a concrete agent-extension lifecycle risk. The inspected skill content is ordinary product guidance and the source shows no separate malicious behavior, so this warrants a warning rather than a block. - **Files touched:** package.json, scripts/postinstall.js, scripts/installer.js, bin/cli.js, skills/specsync/SKILL.md - **Network endpoints:** https://github.com/androidand/specsync/releases ### Review decision - **Verdict:** Suspicious - **Confidence:** 91.0% - **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 postinstall hook creates and overwrites a SpecSync skill in global directories for several AI agents, including Codex., The skill content describes normal SpecSync planning and tracker-sync workflows., The installer downloads a platform-specific release and checks it against the release checksum file. - **Evidence against:** The inspected skill contains product workflow guidance, and the installer fetches the release from the project’s GitHub repository., The inspected sources do not show credential collection, unrelated data transfer, or broader agent configuration changes. ## Affected versions and remediation This report applies to @androidand/specsync@0.14.1. - Review the evidence and your use of @androidand/specsync@0.14.1 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.
