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:** 0.4.3 - **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 shows an explicit CLI capability to install package-owned skills into agent configuration, which warrants a warning under the agent configuration policy. The manifest has no install lifecycle hook, and the inspected code does not establish unconsented mutation or another concrete attack. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Recorded final verdict:** Suspicious - **Recorded analysis confidence:** 89.0% - **Started:** 2026-10-11T00:47:48.820Z - **Finished:** 2026-10-11T00:48:30.213Z - **Download time:** 1040 ms - **Static scan time:** 35 ms - **AI review time:** 40317 ms - **Total time:** 41393 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:** No confirmed attack was identified. The CLI can install its packaged skills into a user agent directory when the user invokes it. - **Trigger:** The user runs the package’s CLI, optionally selecting a target or --force. - **Impact:** This changes agent configuration by making the package’s skills available to the user’s agents. - **Evidence paths:** bin/fabric-agent-adapter.js - **Review source:** ai\_review - **Reviewed:** 2026-10-11T00:48:30.213Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** The CLI copies packaged skill files into the user’s agent skills directory; existing destinations are skipped unless --force is used. - **Rationale:** The source shows an explicit CLI capability to install package-owned skills into agent configuration, which warrants a warning under the agent configuration policy. The manifest has no install lifecycle hook, and the inspected code does not establish unconsented mutation or another concrete attack. - **Files touched:** ~/.agents/skills, ~/.claude/skills ### Review decision - **Verdict:** Suspicious - **Confidence:** 89.0% - **Recommended action:** downgrade\_to\_warn - **Intent class:** Dangerous Capability - **False-positive risk:** Medium - **Evidence for warning:** The package exposes an installer CLI and has no install lifecycle hook; its only script is a test command., The CLI checks whether the package’s Claude plugin is installed before handling target-specific skill installation., When invoked, the CLI can copy packaged skills into the user’s shared agent skills directory, so it has an explicit-user-command agent configuration capability. - **Evidence against:** The manifest defines no preinstall, install, or postinstall behavior., Skill installation is triggered through the CLI, and existing destinations are skipped unless --force is supplied. ## Affected versions and remediation This report applies to @passioncode-ai/fabric-agent-adapter@0.4.3. - Review the evidence and your use of @passioncode-ai/fabric-agent-adapter@0.4.3 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.
