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 manifest has no install lifecycle hook, the library entry point only re-exports circuit-design modules, and the CLI’s visible startup work configures a bundled file path before loading its CLI implementation. The inspected network references are for tscircuit routing and cache features, with no credential collection or unrelated execution identified. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Recorded final verdict:** Clean - **Recorded analysis confidence:** 87.0% - **Started:** 2026-11-04T13:27:39.385Z - **Finished:** 2026-11-04T13:28:27.925Z - **Download time:** 1538 ms - **Static scan time:** 61 ms - **AI review time:** 46940 ms - **Total time:** 48540 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; the reviewed behavior matches an electronics design library and CLI. - **Trigger:** The library loads when imported; the CLI implementation loads when a user runs its command. - **Impact:** No malicious impact was identified in the reviewed package source. - **Review source:** ai\_review - **Reviewed:** 2026-11-04T13:28:27.925Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** The library entry point re-exports circuit-design functionality. The CLI selects a bundled standalone file path and imports the CLI package. - **Rationale:** The manifest has no install lifecycle hook, the library entry point only re-exports circuit-design modules, and the CLI’s visible startup work configures a bundled file path before loading its CLI implementation. The inspected network references are for tscircuit routing and cache features, with no credential collection or unrelated execution identified. - **Files touched:** package.json, dist/index.js, cli.mjs, dist/webworker.min.js - **Network endpoints:** https://registry-api.tscircuit.com, https://hd-cache.tscircuit.com, https://hd-cache2.tscircuit.com ### Review decision - **Verdict:** Clean - **Confidence:** 87.0% - **Recommended action:** mark\_clean - **Intent class:** Benign - **False-positive risk:** Low - **Evidence for AI clean decision:** The package describes itself as an electronics design tool for creating and previewing circuit boards., The library entry point re-exports circuit functionality from @tscircuit/core and @tscircuit/eval, plus React and circuit properties., The CLI sets a package-local standalone bundle path and imports @tscircuit/cli when the CLI is run., The manifest exposes the library and CLI entry points and lists no install lifecycle script. ## Affected versions and remediation This report applies to tscircuit@0.0.3076. - Review the evidence and your use of tscircuit@0.0.3076 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.
