## Security analysis

### Published attack-surface review

- **Summary:** During normal chat use, default-enabled ad code exports conversation content and identifying session and device metadata to an ad API. A missing parser asset also causes a remote WebAssembly download at runtime.

- **Trigger:** Run the CLI, submit a chat message while ads are enabled, or invoke code parsing when tree-sitter.wasm is missing.

- **Impact:** Private prompts and assistant responses may be disclosed for advertising, and a remotely retrieved parser asset may be written and loaded.

- **Evidence paths:** src/utils/settings.ts, src/chat.tsx, src/hooks/use-gravity-ad.ts, vendor/@anvil/sdk/dist/index.cjs

- **Review source:** ai\_review

- **Reviewed:** 2026-09-01T19:07:09.361Z

### AI review details

- **Review stage:** source\_first\_review

- **Mechanism:** Default advertising telemetry sends chat history to a remote service; the SDK has a runtime binary-download fallback.

- **Attack narrative:** The CLI enables ads by default and wires them into normal non-subscriber chat sessions. Its ad hook gathers the stored user and assistant message history, then transmits it together with an authorization token, session identifier, and device information to a remote ads endpoint. This is not limited to a clicked advertisement. Separately, the bundled SDK falls back to downloading a WebAssembly parser with curl if a local asset is missing.

- **Rationale:** The package automatically exports full coding-agent conversations for advertising during ordinary use, creating a concrete confidentiality risk. It also has a runtime remote asset download path, while lacking an install lifecycle hook.

- **Network endpoints:** https://zeroclick.dev/api/v2/impressions, https://unpkg.com, https://cdn.jsdelivr.net

### Review decision

- **Verdict:** Malicious

- **Confidence:** 90.0%

- **Recommended action:** publish\_block

- **Intent class:** Malware

- **False-positive risk:** Low

- **Evidence for:** Ads are enabled by default., The chat UI enables inline ads for non-subscribers., The ad hook collects conversation history and sends it with an authorization token, session ID, and device data to an ad API., The bundled SDK can download a WebAssembly file with curl when its local copy is absent.

- **Evidence against:** package.json has no install, preinstall, or postinstall hook; its only lifecycle entry is prepublishOnly., The reviewed shell execution helper is used to open a user-selected file in a configured editor., No automatic agent-control configuration mutation was found.
