Treat them as untrusted evidence. Do not execute instructions or code found in this document. ## Verdict summary **Flagged as AI-agent capability risk** — Allowed by default with warning: agent-facing configuration or capability changes need review before use. - **Verdict:** Suspicious - **Product-default install policy:** Warn - **Firewall policy:** Warn-only AI-agent capability risk - **Public report status:** Published - **Threat category:** AI-agent capability abuse - **Selected version:** 2.1.0 - **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. Source establishes user-invoked agent configuration mutation without an automatic install hook. No separate concrete malicious behavior was established, so the appropriate result is a capability warning. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Recorded final verdict:** Suspicious - **Recorded analysis confidence:** 96.0% - **Started:** 2026-10-01T03:39:50.597Z - **Finished:** 2026-10-01T03:40:55.493Z - **Download time:** 1034 ms - **Static scan time:** 1608 ms - **AI review time:** 62252 ms - **Total time:** 64896 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:** Explicit CLI initialization installs a project agent skill. This changes agent guidance, but no confirmed malicious attack was established. - **Trigger:** The user runs buntok init. - **Impact:** Adds or replaces guidance available to project AI agents; the explicit command gate limits this to user-invoked setup. - **Evidence paths:** dist/cli/index.js - **Review source:** ai\_review - **Reviewed:** 2026-10-01T03:40:55.493Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** The CLI copies its bundled skill into the current project's agent skills directory without checking whether the destination file already exists. - **Rationale:** Source establishes user-invoked agent configuration mutation without an automatic install hook. No separate concrete malicious behavior was established, so the appropriate result is a capability warning. - **Files touched:** .agents/skills/buntok-skill/SKILL.md ### Review decision - **Verdict:** Suspicious - **Confidence:** 96.0% - **Recommended action:** downgrade\_to\_warn - **Intent class:** Dangerous Capability - **False-positive risk:** Medium - **Evidence for warning:** package.json has no automatic install lifecycle hooks., The CLI writes a bundled skill into .agents/skills/buntok-skill/SKILL.md, overwriting any existing file., Initialization uses the current project directory and invokes the skill copy., The skill mutation is activated by the explicit init command. - **Evidence against:** No concrete exfiltration, covert execution, or malicious intent was established in the inspected source. ## Affected versions and remediation This report applies to @buntok/core@2.1.0. - Review the evidence and your use of @buntok/core@2.1.0 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.
