This remains warn-only unless evidence shows foreign-agent hijack through preinstall/install/postinstall, hidden persistence, exfiltration, remote code execution, or other concrete malicious behavior. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Verdict:** Suspicious - **Confidence:** 90.0% - **Started:** 2026-08-17T21:02:31.843Z - **Finished:** 2026-08-17T21:05:09.910Z - **Download time:** 1009 ms - **Static scan time:** 1688 ms - **AI review time:** 155369 ms - **Total time:** 158067 ms ## Security analysis ### Published attack-surface review - **Summary:** User-invoked \`tsci init\` can download and write a tscircuit skill into Claude and Codex-style project skill directories. User-invoked \`tsci check shorts\` dynamically imports a CDN module. - **Trigger:** Run \`tsci init\` (especially \`--yes\`) or \`tsci check shorts\`. - **Impact:** Downloaded skill content can influence AI agents operating in the initialized project; CDN content executes in the CLI process when the shorts check is run. - **Evidence paths:** package.json, cli/entrypoint.js, dist/cli/main.js - **Review source:** ai\_review - **Reviewed:** 2026-08-17T21:05:09.910Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** Remote skill installation and dynamic CDN module import. - **Rationale:** No concrete malicious install-time or credential-exfiltration chain was found, but explicit initialization mutates AI-agent skill surfaces using remotely fetched content. This warrants a warning under the agent-control policy, not a block. - **Files touched:** .claude/skills/tscircuit, .agents/skills/tscircuit - **Network endpoints:** https://api.github.com/repos/tscircuit/skill/contents, https://jscdn.tscircuit.com/@tscircuit/check-shorts/latest/+esm ### Review decision - **Verdict:** Suspicious - **Confidence:** 90.0% - **Recommended action:** downgrade\_to\_warn - **Intent class:** Dangerous Capability - **False-positive risk:** Low - **Evidence for:** \`tsci init\` downloads a remote skill repository into \`.claude\` and \`.agents\` project skill paths., The skill setup is prompted normally but is automatic with \`tsci init --yes\`., \`check shorts\` dynamically imports code from the tscircuit CDN. - **Evidence against:** package.json has no npm preinstall, install, or postinstall hook., Agent-skill writes occur only through the user-invoked \`init\` command., The normal init flow asks for confirmation before installing skills., No credential harvesting, destructive behavior, or stealth persistence was found in inspected entrypoints. ## Public findings ### 1.
