Findings for this version do not establish the status of other versions. AI assessment: clean; recommendation: mark clean. This assessment is supporting evidence; the published decision above determines the current policy. The source does not substantiate the scanner’s credential-redirection or persistent agent-control claims. The manifest has no install hook, and the inspected runtime paths align with the declared CLI and hosted-tool functionality. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Recorded final verdict:** Clean - **Recorded analysis confidence:** 90.0% - **Started:** 2026-10-17T03:29:56.473Z - **Finished:** 2026-10-17T03:30:55.872Z - **Download time:** 774 ms - **Static scan time:** 7080 ms - **AI review time:** 51544 ms - **Total time:** 59399 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 attack was identified in the inspected package source. The flagged agent integration prepares runtime-local hosted tools, and the inspected credential path uses the saved OpenTag server. - **Trigger:** The CLI runs when invoked, or the exported runtime API is called by a consumer. - **Impact:** The inspected behavior supports the package’s CLI and agent integration; no credential redirection or persistent agent configuration change was established. - **Review source:** ai\_review - **Reviewed:** 2026-10-17T03:30:55.872Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** No install hook is present. The inspected Claude Code bridge writes a temporary MCP configuration for a loopback tool server; authenticated API context uses the saved OpenTag server URL. - **Rationale:** The source does not substantiate the scanner’s credential-redirection or persistent agent-control claims. The manifest has no install hook, and the inspected runtime paths align with the declared CLI and hosted-tool functionality. - **Files touched:** package.json, dist/cli/index.mjs, dist/index.mjs, dist/program-CXdTyo53.mjs, dist/index.d.mts ### Review decision - **Verdict:** Clean - **Confidence:** 90.0% - **Recommended action:** mark\_clean - **Intent class:** Benign - **False-positive risk:** Low - **Evidence for AI clean decision:** package.json points to a CLI and runtime module and defines no install lifecycle hook., The CLI runs when its executable is invoked; package.json lists only build, start, typecheck, and test scripts., The flagged agent-related code lists skill directories and prepares a Claude Code hosted-tool bridge during runtime., That bridge uses a temporary configuration and a loopback server for OpenTag tools., Authenticated API requests use the server URL saved in OpenTag credentials., The declaration file exposes the package’s command and result APIs. ## Affected versions and remediation This report applies to open-tag@0.1.1. - Review the evidence and your use of open-tag@0.1.1 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.
