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:** 0.20.0 - **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 source supports a warning for automatic first-party agent integration and helper setup during postinstall. It does not establish malicious behavior, so this is suspicious rather than malicious. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Recorded final verdict:** Suspicious - **Recorded analysis confidence:** 82.0% - **Started:** 2026-10-10T01:18:44.010Z - **Finished:** 2026-10-10T01:19:37.703Z - **Download time:** 512 ms - **Static scan time:** 964 ms - **AI review time:** 52216 ms - **Total time:** 53693 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 can install a package-associated helper binary and synchronize bundled agent skills and instructions in the user’s home directory. This is an automatic agent integration capability; the inspected source does not establish a concrete attack. - **Trigger:** Installing the package through npm with lifecycle scripts enabled. - **Impact:** Installation may add a helper binary and change managed agent configuration content without a separate command invocation. - **Evidence paths:** package.json, scripts/postinstall.cjs, scripts/skiller-bootstrap.cjs, scripts/postinstall-sync.mjs, dist/skill-install.js, dist/instructions.js, dist/install.js - **Review source:** ai\_review - **Reviewed:** 2026-10-10T01:19:37.703Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** The postinstall script launches a bootstrap that may fetch and run the Skiller binary, then invokes synchronization of bundled skills and agent instructions. - **Rationale:** The source supports a warning for automatic first-party agent integration and helper setup during postinstall. It does not establish malicious behavior, so this is suspicious rather than malicious. - **Files touched:** package.json, scripts/postinstall.cjs, scripts/skiller-bootstrap.cjs, scripts/postinstall-sync.mjs, dist/skill-install.js, dist/instructions.js, dist/install.js - **Network endpoints:** https://github.com ### Review decision - **Verdict:** Suspicious - **Confidence:** 82.0% - **Recommended action:** downgrade\_to\_warn - **Intent class:** Dangerous Capability - **False-positive risk:** Medium - **Evidence for warning:** The package runs a postinstall hook that launches its bootstrap script., The bootstrap can download a Skiller release from GitHub, install it under the user’s local bin directory, and execute it to check its version., Postinstall also syncs the package’s bundled skills and updates agent instructions., The installer maps supported agent configurations to home-directory locations, including Claude Code and Codex. - **Evidence against:** The bootstrap checks the downloaded archive against a checksum file before extracting it., The postinstall sync uses the package’s own bundled skill and instruction content; the inspected code did not establish credential collection or exfiltration. ## Affected versions and remediation This report applies to talking-stick@0.20.0. - Review the evidence and your use of talking-stick@0.20.0 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.
