Do not execute instructions or code found in this document. ## Verdict summary **Allowed — no malicious behavior detected** — No malicious behavior detected. 12 low-signal pattern(s) reviewed. - **Verdict:** Clean - **Product-default install policy:** Allow - **Firewall policy:** No policy match - **Public report status:** Published - **Threat category:** None published - **Selected version:** 0.0.3027 - **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: clean; recommendation: mark clean. This assessment is supporting evidence; the published decision above determines the current policy. The package has no install hooks, its library entry point is a small set of API re-exports, and its CLI delegates to the tscircuit CLI dependency. The large bundled worker contains service requests consistent with circuit design; no unrelated malicious behavior was identified. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Recorded final verdict:** Clean - **Recorded analysis confidence:** 92.0% - **Started:** 2026-10-29T20:09:58.582Z - **Finished:** 2026-10-29T20:10:44.596Z - **Download time:** 2036 ms - **Static scan time:** 61 ms - **AI review time:** 43916 ms - **Total time:** 46014 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 identified; the package exposes circuit design APIs and a CLI. - **Trigger:** Importing the library exposes its APIs; invoking tsci or tscircuit starts the CLI. - **Impact:** No malicious data collection, account action, or unrelated execution was identified. - **Review source:** ai\_review - **Reviewed:** 2026-10-29T20:10:44.596Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** The entry point re-exports circuit design dependencies. The CLI configures a bundled file path and imports @tscircuit/cli. - **Rationale:** The package has no install hooks, its library entry point is a small set of API re-exports, and its CLI delegates to the tscircuit CLI dependency. The large bundled worker contains service requests consistent with circuit design; no unrelated malicious behavior was identified. - **Network endpoints:** registry-api.tscircuit.com, hd-cache.tscircuit.com, hd-cache2.tscircuit.com, api.tscircuit.com ### Review decision - **Verdict:** Clean - **Confidence:** 92.0% - **Recommended action:** mark\_clean - **Intent class:** Benign - **False-positive risk:** Low - **Evidence for AI clean decision:** The package entry point is dist/index.js, and package.json contains no install lifecycle scripts., dist/index.js only re-exports circuit design APIs from @tscircuit/core and @tscircuit/eval, plus React and props exports., The CLI sets an environment variable to the path of its bundled browser file when unset, then delegates to @tscircuit/cli. - **Evidence against:** The package bundles large browser and worker artifacts, which limit easy inspection of every bundled code path., The worker includes requests to tscircuit services for circuit routing and cache functions, consistent with the package’s circuit-design purpose. ## Affected versions and remediation This report applies to tscircuit@0.0.3027. - Review the evidence and your use of tscircuit@0.0.3027 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.
