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. Inspected source resolves the scanner’s credential, dynamic-code, and agent-configuration hints as an official Anthropic credential check, an empty-function feature test, and a temporary MCP configuration. The dependency install hook exits for nested installs, and no confirmed attack surface remains. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Recorded final verdict:** Clean - **Recorded analysis confidence:** 97.0% - **Started:** 2026-10-22T11:53:17.560Z - **Finished:** 2026-10-22T11:54:57.760Z - **Download time:** 1266 ms - **Static scan time:** 7751 ms - **AI review time:** 91183 ms - **Total time:** 100200 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 entrypoints. The credential check targets Anthropic’s official endpoint, and the MCP configuration is temporary. - **Trigger:** The credential check runs when the CLI probes a logged-in first-party Claude Code setup; the dependency hook has a separate direct-global-install condition. - **Impact:** The inspected paths establish no unrelated credential disclosure or persistent foreign agent-configuration change. - **Review source:** ai\_review - **Reviewed:** 2026-10-22T11:54:57.760Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** The CLI validates the configured Anthropic destination before sending credentials. The dependency hook exits when installed inside another package. - **Rationale:** Inspected source resolves the scanner’s credential, dynamic-code, and agent-configuration hints as an official Anthropic credential check, an empty-function feature test, and a temporary MCP configuration. The dependency install hook exits for nested installs, and no confirmed attack surface remains. - **Files touched:** package.json, dist/program-DtKWcSL6.mjs, dist/index.d.mts, .lpm-dependency-evidence-b2a244ac-cead-4e96-8a09-cba237c4a73c/0/npm-linux/package.json, .lpm-dependency-evidence-b2a244ac-cead-4e96-8a09-cba237c4a73c/0/npm-linux/scripts/postinstall.mjs - **Network endpoints:** https://api.anthropic.com/v1/models?limit=1 ### Review decision - **Verdict:** Clean - **Confidence:** 97.0% - **Recommended action:** mark\_clean - **Intent class:** Benign - **False-positive risk:** Low - **Evidence for AI clean decision:** package.json exposes the CLI and import entrypoint, has no install lifecycle script, and declares context-tree@0.1.16; dist/index.d.mts declares typed APIs., The Claude credential probe is limited to logged-in first-party setups; unsupported backends and nondefault Anthropic base URLs skip it., The credential check sends credentials to the fixed official Anthropic models endpoint., The dynamic Function match creates an empty function in a caught feature test; it does not evaluate package-supplied code., The MCP configuration is written under an OS temporary directory for the run., The dependency postinstall proceeds only for a direct global install, and exits when installed as another package’s dependency. ## Affected versions and remediation This report applies to open-tag@0.1.3. - Review the evidence and your use of open-tag@0.1.3 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.
