The package is a user-invoked circuit-design CLI with expected project-file execution and model-fetch features. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Verdict:** Clean - **Confidence:** 94.0% - **Started:** 2026-08-13T01:37:46.989Z - **Finished:** 2026-08-13T01:38:23.184Z - **Download time:** 1279 ms - **Static scan time:** 1508 ms - **AI review time:** 33406 ms - **Total time:** 36195 ms ## Security analysis ### Published attack-surface review - **Summary:** No confirmed malicious attack surface. The package is a user-invoked circuit-design CLI with expected project-file execution and model-fetch features. - **Trigger:** User runs the tscircuit-cli command or an explicit CLI subcommand. - **Impact:** User-directed commands may read project files, generate artifacts, and contact the tscircuit registry or user-specified model URLs; no unconsented install-time action was found. - **Evidence paths:** package.json, cli/entrypoint.js, dist/cli/main.js, dist/cli/build/build.worker.js, dist/cli/snapshot/snapshot.worker.js - **Review source:** ai\_review - **Reviewed:** 2026-08-13T01:38:23.184Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** CLI forwards arguments to bundled circuit build, project, and registry tooling. - **Rationale:** Direct inspection found no lifecycle hooks, stealth persistence, credential exfiltration, or malicious execution chain. Flagged primitives are consistent with an explicitly invoked circuit-design CLI and bundled dependencies. - **Files touched:** cli/entrypoint.js, dist/cli/main.js, dist/cli/build/build.worker.js, dist/cli/snapshot/snapshot.worker.js, package.json - **Network endpoints:** https://registry-api.tscircuit.com ### Review decision - **Verdict:** Clean - **Confidence:** 94.0% - **Recommended action:** mark\_clean - **Intent class:** Benign - **False-positive risk:** Low - **Evidence for:** Manifest has no preinstall, install, or postinstall lifecycle hook., The bin entrypoint only selects Bun/tsx and forwards user-supplied arguments to the packaged CLI., Flagged dynamic imports load project configuration/modules during explicit CLI operations; no hidden import-time execution found. - **Evidence against:** No credential collection or outbound exfiltration path was found., Remote STEP downloads are explicitly limited to HTTP(S) model URLs used by build functionality., AJV's bundled new Function usage is schema-validator code generation., Auth and .npmrc mutation are explicit auth/setup commands, not install-time behavior. ## Public findings ### 1.
