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 manifest and inspected entry points show no install hooks or suspicious import-time behavior. The visible network configuration belongs to tscircuit’s circuit evaluation services. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Recorded final verdict:** Clean - **Recorded analysis confidence:** 94.0% - **Started:** 2026-10-29T20:10:09.682Z - **Finished:** 2026-10-29T20:10:53.958Z - **Download time:** 2331 ms - **Static scan time:** 58 ms - **AI review time:** 41886 ms - **Total time:** 44276 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 package exposes circuit design and evaluation functionality. - **Trigger:** Importing the library loads its core and evaluator dependencies; invoking the CLI delegates to @tscircuit/cli. - **Impact:** No malicious impact was identified in the inspected source. - **Review source:** ai\_review - **Reviewed:** 2026-10-29T20:10:53.958Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** The inspected entry points re-export package functionality, and the evaluator is configured to use tscircuit service hosts. - **Rationale:** The package manifest and inspected entry points show no install hooks or suspicious import-time behavior. The visible network configuration belongs to tscircuit’s circuit evaluation services. - **Files touched:** cli.mjs - **Network endpoints:** https://registry-api.tscircuit.com, https://cjs.tscircuit.com ### Review decision - **Verdict:** Clean - **Confidence:** 94.0% - **Recommended action:** mark\_clean - **Intent class:** Benign - **False-positive risk:** Low - **Evidence for AI clean decision:** The manifest points the library entry to dist/index.js and declares no install lifecycle scripts., dist/index.js re-exports the circuit core and evaluator; no additional top-level behavior is present in the entry file., The CLI wrapper sets a local standalone bundle path when needed, then delegates to @tscircuit/cli., The evaluator’s configured service URLs are tscircuit hosts, consistent with fetching circuit snippets and related data. - **Evidence against:** The package includes a large minified webworker bundle, which is difficult to review linearly., The CLI dependency source was unresolved in the prepared dependency evidence. ## Affected versions and remediation This report applies to tscircuit@0.0.3031. - Review the evidence and your use of tscircuit@0.0.3031 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.

Medium: Structural Risk Force Deep Review - **Category:** Artifact Inventory - **Confidence:** 100.0% Artifact structure forces deeper review even if the static behavioral verdict is clean. ### 8. Low: Suspicious Lifecycle Evidence - **Category:** Manifest - **Confidence:** 94.0% - **Path:** package.json - **Public source:** [View source]() The manifest points the library entry to dist/index.js and declares no install lifecycle scripts. Public source snippet (untrusted): ```json { "name": "tscircuit", "main": "dist/index.js", "types": "dist/index.d.ts", "type": "module", "version": "0.0.3031", "license": "MIT", "repository": { "type": "gi ``` ### 9. Low: Ai Review Evidence - **Category:** Ai Review - **Confidence:** 94.0% - **Path:** dist/index.js - **Public source:** [View source]() dist/index.js re-exports the circuit core and evaluator; no additional top-level behavior is present in the entry file. Public source snippet (untrusted): ```javascript // index.ts export * from "@tscircuit/core"; import { jscad } from "@tscircuit/core"; export * from "@tscircuit/eval"; import { Fragment } from "react"; import { kicadFootprintStr ``` ### 10. Low: Ai Review Evidence - **Category:** Ai Review - **Confidence:** 94.0% - **Path:** cli.mjs - **Public source:** [View source]() The CLI wrapper sets a local standalone bundle path when needed, then delegates to @tscircuit/cli. Public source snippet (untrusted): ```javascript if (!process.env.TSCIRCUIT_GLOBAL_STANDALONE_FILE_PATH) { const browserBundlePath = join( dirname(fileURLToPath(import.meta.url)), "dist", "browser.min.js", ); if (existsSync(browserBundlePath)) { process.env.TSCIRCUIT_GLOBAL_STANDALONE_FILE_PATH = browserBundlePath; } } async functio ``` ### 11.
