Explicit \`tsci init\` can install remotely fetched TSCircuit AI skills into project AI-agent skill directories. Explicit analog simulation downloads and imports a remote JavaScript module. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Verdict:** Suspicious - **Confidence:** 91.0% - **Started:** 2026-08-14T19:58:14.113Z - **Finished:** 2026-08-14T19:59:28.065Z - **Download time:** 1268 ms - **Static scan time:** 1673 ms - **AI review time:** 71010 ms - **Total time:** 73952 ms ## Security analysis ### Published attack-surface review - **Summary:** Explicit \`tsci init\` can install remotely fetched TSCircuit AI skills into project AI-agent skill directories. Explicit analog simulation downloads and imports a remote JavaScript module. - **Trigger:** Run \`tsci init\` (especially \`--yes\`) or \`tsci simulate analog \\`. - **Impact:** A project AI-agent control surface can be populated with mutable remote content; simulation executes mutable CDN code. - **Evidence paths:** package.json, cli/entrypoint.js, dist/cli/main.js - **Review source:** ai\_review - **Reviewed:** 2026-08-14T19:59:28.065Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** Remote content download into agent skill paths and temp-file dynamic module import. - **Rationale:** This is not malware or an install-time attack, but it creates a guarded AI-agent extension lifecycle risk and includes user-triggered remote code loading without integrity verification. - **Files touched:** .claude/skills/tscircuit, .agents/skills/tscircuit, $TMPDIR/tscircuit-eecircuit-engine-1.7.4.mjs - **Network endpoints:** https://api.github.com/repos/tscircuit/skill/contents, https://jscdn.tscircuit.com/@tscircuit/eecircuit-engine/1.7.4/dist/eecircuit-engine.mjs ### Review decision - **Verdict:** Suspicious - **Confidence:** 91.0% - **Recommended action:** downgrade\_to\_warn - **Intent class:** Dangerous Capability - **False-positive risk:** Low - **Evidence for:** \`tsci init\` downloads a remote repository into \`.claude/skills/tscircuit\` and \`.agents/skills/tscircuit\`., \`tsci init --yes\` skips the skill-install confirmation., Analog simulation fetches a CDN module to a temp file and dynamically imports it without integrity verification. - **Evidence against:** package.json has no preinstall, install, or postinstall lifecycle hook., The AI-skill write and remote module load occur only after explicit CLI commands, not on package installation., The normal init path presents a confirmation prompt before installing AI skills. ## Public findings ### 1.
