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:** 2.1.2 - **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 explicit setup command mutates an agent control surface, which warrants a warning under the supplied policy. No automatic lifecycle mutation or concrete malicious behavior was established. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Recorded final verdict:** Suspicious - **Recorded analysis confidence:** 94.0% - **Started:** 2026-10-01T03:39:08.197Z - **Finished:** 2026-10-01T03:40:44.861Z - **Download time:** 1035 ms - **Static scan time:** 2535 ms - **AI review time:** 93092 ms - **Total time:** 96664 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:** An explicit CLI setup command installs package-supplied agent guidance into the consumer project. No confirmed malicious attack or automatic install-time mutation was established. - **Trigger:** The user runs buntok init. - **Impact:** Subsequent agents can consume package-supplied guidance, and an existing skill at that destination can be overwritten. - **Evidence paths:** dist/cli/index.js, dist/cli/index.cjs - **Review source:** ai\_review - **Reviewed:** 2026-10-01T03:40:44.861Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** The CLI creates the project skill directory and writes the bundled SKILL.md into it. - **Rationale:** The explicit setup command mutates an agent control surface, which warrants a warning under the supplied policy. No automatic lifecycle mutation or concrete malicious behavior was established. - **Files touched:** .agents/skills/buntok-skill/SKILL.md ### Review decision - **Verdict:** Suspicious - **Confidence:** 94.0% - **Recommended action:** downgrade\_to\_warn - **Intent class:** Dangerous Capability - **False-positive risk:** Medium - **Evidence for warning:** The CLI writes the bundled skill into the consumer project's .agents/skills/buntok-skill/SKILL.md; both CLI formats implement this write., The write is activated by the explicit buntok init command using the current project directory., package.json defines development scripts but no automatic install lifecycle hook. - **Evidence against:** The inspected skill content provides framework usage guidance., Inspected OAuth and email requests use caller-supplied configuration for their service operations; no covert credential export was established. ## Affected versions and remediation This report applies to @buntok/core@2.1.2. - Review the evidence and your use of @buntok/core@2.1.2 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.
