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:** 95.0% - **Started:** 2026-08-07T23:51:26.501Z - **Finished:** 2026-08-07T23:52:17.277Z - **Download time:** 757 ms - **Static scan time:** 971 ms - **AI review time:** 49048 ms - **Total time:** 50776 ms ## Security analysis ### Published attack-surface review - **Summary:** Explicit CLI use creates a remote-control client that can execute shell commands, automate macOS UI actions, and return results over a Tahcia WebSocket. Its explicit antigravity mode launches an unrestricted agent daemon reachable on all interfaces and posts agent results to Tahcia. - **Trigger:** User runs tahcia with a session, especially \`tahcia \ antigravity\`. - **Impact:** A party controlling the authenticated Tahcia session or reachable daemon can cause local command/UI actions and receive their output. - **Evidence paths:** package.json, tahcia.js, tahcia-antigravity.py, tahcia - **Review source:** ai\_review - **Reviewed:** 2026-08-07T23:52:17.277Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** Remote command relay and unrestricted AI-agent daemon. - **Rationale:** This is a concrete, high-risk remote-control and agent-execution capability, but it is user-invoked and has no installation-time or stealth execution path. It warrants a warning rather than a malware block under the stated policy. - **Files touched:** tahcia.js, tahcia-antigravity.py, tahcia-mac - **Network endpoints:** https://api.tahcia.com, wss://api.tahcia.com/wss ### Review decision - **Verdict:** Suspicious - **Confidence:** 95.0% - **Recommended action:** downgrade\_to\_warn - **Intent class:** Dangerous Capability - **False-positive risk:** Low - **Evidence for:** tahcia.js:10418 executes WebSocket-delivered shell text and returns its output., tahcia-antigravity.py:146 enables an unrestricted agent policy by default., tahcia-antigravity.py:172 starts an unauthenticated server on 0.0.0.0 and forwards agent output to the vendor API., tahcia.js:10313 accepts remote system/mouse/keyboard commands and executes the bundled macOS helper., tahcia.js:11025 loads backend configuration that can supply workspaces and interpreter path. - **Evidence against:** package.json has no preinstall, install, postinstall, or prepare hook., All risky behavior requires an explicit CLI command/session; no import-time connection or execution is present., Network traffic is to the package-aligned api.tahcia.com endpoint., OpenClaw manifest files are written only for the explicit openclaw-plugin-json command. ## Public findings ### 1.
