Running \`tsci init\` can download and write tscircuit AI skills into two project agent-skill directories. No install-time execution is present. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Verdict:** Suspicious - **Confidence:** 90.0% - **Started:** 2026-08-14T15:41:15.249Z - **Finished:** 2026-08-14T15:41:57.532Z - **Download time:** 1013 ms - **Static scan time:** 2875 ms - **AI review time:** 38393 ms - **Total time:** 42283 ms ## Security analysis ### Published attack-surface review - **Summary:** Running \`tsci init\` can download and write tscircuit AI skills into two project agent-skill directories. No install-time execution is present. - **Trigger:** Explicit \`tsci init\`, including noninteractive \`--yes\`. - **Impact:** Adds vendor-controlled instructions to Claude and agent skill discovery paths in the initialized project. - **Evidence paths:** package.json, dist/cli/main.js, cli/entrypoint.js - **Review source:** ai\_review - **Reviewed:** 2026-08-14T15:41:57.532Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** Remote AI-skill download and project control-surface write. - **Rationale:** No malicious install hook, credential harvesting, or covert exfiltration was found. However, explicit initialization can automatically populate broad project AI-agent skill paths from a remote repository, warranting a warning. - **Files touched:** .claude/skills/tscircuit, .agents/skills/tscircuit - **Network endpoints:** https://api.github.com/repos/tscircuit/skill/contents ### Review decision - **Verdict:** Suspicious - **Confidence:** 90.0% - **Recommended action:** downgrade\_to\_warn - **Intent class:** Dangerous Capability - **False-positive risk:** Low - **Evidence for:** \`tsci init\` provisions AI skills in \`.claude\` and \`.agents\` project control paths., The skill setup downloads repository content and writes it into those paths., \`--yes\` passes a skip-prompt flag to the AI-skill setup. - **Evidence against:** package.json has no npm preinstall/install/postinstall lifecycle hook., The mutation is reached only through the explicit \`init\` CLI command., Default interactive init presents a confirmation prompt before setup. ## Public findings ### 1.
