User-invoked project initialization may populate first-party TSCircuit skills in AI-agent directories. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Verdict:** Suspicious - **Confidence:** 86.0% - **Started:** 2026-08-13T01:41:46.579Z - **Finished:** 2026-08-13T01:42:29.660Z - **Download time:** 1758 ms - **Static scan time:** 1709 ms - **AI review time:** 39613 ms - **Total time:** 43081 ms ## Security analysis ### Published attack-surface review - **Summary:** User-invoked simulation fetches and executes a CDN module without an in-package integrity check. User-invoked project initialization may populate first-party TSCircuit skills in AI-agent directories. - **Trigger:** Running simulation features or \`tsci init\` (including \`--yes\`). - **Impact:** A compromised CDN or GitHub content could execute code or alter project AI-agent instructions. - **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:** 2026-08-13T01:42:29.660Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** Runtime remote module import and explicit agent-skill installation. - **Rationale:** No concrete malicious install-time behavior was found, but unauthenticated runtime remote-code loading is a real supply-chain execution surface. The AI-agent writes are explicit command behavior and do not justify a block. - **Files touched:** \/tscircuit-eecircuit-engine-1.7.4.mjs, .claude/skills/tscircuit, .agents/skills/tscircuit - **Network endpoints:** https://jscdn.tscircuit.com/@tscircuit/eecircuit-engine/1.7.4/dist/eecircuit-engine.mjs, https://api.github.com/repos/tscircuit/skill/contents ### Review decision - **Verdict:** Suspicious - **Confidence:** 86.0% - **Recommended action:** downgrade\_to\_warn - **Intent class:** Dangerous Capability - **False-positive risk:** Low - **Evidence for:** Runtime simulation downloads JavaScript from a CDN, saves it in the temp directory, then imports it., The explicit \`init\` command can download and write TSCircuit skills into \`.claude\` and \`.agents\` project paths., No npm preinstall/install/postinstall hook is declared. - **Evidence against:** Remote-code and skill writes are in named CLI features, not install-time execution., Skill setup prompts by default; \`init --yes\` is an explicit user command., The launcher only selects Bun/tsx and forwards user CLI arguments. ## Public findings ### 1.
