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:** 0.5.3 - **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 package has an explicit CLI that installs its own skills into shared agent directories, a concrete agent configuration capability. The behavior is product-aligned and user-invoked, 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:** 84.0% - **Started:** 2026-10-11T00:47:52.803Z - **Finished:** 2026-10-11T00:48:18.733Z - **Download time:** 1033 ms - **Static scan time:** 50 ms - **AI review time:** 24846 ms - **Total time:** 25930 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 CLI installs this package's skills into a shared agent skills directory. This is an explicit setup capability; no attack was identified in the inspected behavior. - **Trigger:** A user runs the fabric-agent-adapter CLI, optionally with --force. - **Impact:** The installed skills become available to agents using those directories; forced installation can replace existing skill content. - **Evidence paths:** bin/fabric-agent-adapter.js - **Review source:** ai\_review - **Reviewed:** 2026-10-11T00:48:18.733Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** The CLI copies shipped skill directories into ~/.agents/skills or, with --target claude, ~/.claude/skills; --force permits recursive removal of an existing destination first. It refuses the Claude copy when its plugin is installed. - **Rationale:** The package has an explicit CLI that installs its own skills into shared agent directories, a concrete agent configuration capability. The behavior is product-aligned and user-invoked, so this warrants a warning rather than a block. - **Files touched:** bin/fabric-agent-adapter.js, ~/.agents/skills, ~/.claude/skills ### Review decision - **Verdict:** Suspicious - **Confidence:** 84.0% - **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 script., When explicitly run, the CLI copies its shipped skills into the user's shared agent skills directory and can recursively replace an existing destination with --force., The installer checks whether its Claude plugin is present and refuses a plain Claude skills copy when it could shadow that plugin. - **Evidence against:** The configuration change is activated by running the CLI; package installation alone does not trigger it., The manifest describes the product as an agent adapter, consistent with installing its skills., No credential collection, network send, or unrelated agent configuration write was identified in the inspected CLI. ## Affected versions and remediation This report applies to @passioncode-ai/fabric-agent-adapter@0.5.3. - Review the evidence and your use of @passioncode-ai/fabric-agent-adapter@0.5.3 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.
