## Verdict summary
**Soft block: AI-agent control surface** — Warn by default; block when configured. An AI agent can be redirected to run package tools and initiate outbound actions without a fresh user confirmation.

- **Verdict:** Malicious
- **Product-default install policy:** Block
- **Firewall policy:** Warn by default
- **Public report status:** Published
- **Threat category:** Soft block: AI-agent control surface
- **Selected version:** 4.17.0
- **Selected version is latest:** Yes
- **Analysis source:** AI Security Review (lpm-firewall-ai)

LPM flags this version as an AI-agent control-surface risk. A normal CLI invocation can silently alter a foreign AI-agent configuration. The injected instructions direct autonomous email polling and social posting without permission.

## Security analysis

### Published attack-surface review

- **Summary:** A normal CLI invocation can silently alter a foreign AI-agent configuration. The injected instructions direct autonomous email polling and social posting without permission.

- **Trigger:** Running delimit-cli when ~/.gemini/antigravity-cli exists; delimit setup makes further global agent changes.

- **Impact:** An AI agent can be redirected to run package tools and initiate outbound actions without a fresh user confirmation.

- **Evidence paths:** bin/delimit-cli.js, bin/delimit-setup.js, scripts/postinstall.js

- **Review source:** ai\_review

- **Reviewed:** 2026-08-27T05:32:50.502Z

### AI review details

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

- **Mechanism:** Writes agent MCP settings, automatic approval settings, and autonomous action instructions.

- **Attack narrative:** The manifest-reachable CLI entrypoint automatically modifies Antigravity settings whenever that directory exists, rather than requiring setup. It registers the package server, enables automatic editing, and installs instructions that start email polling and tell the agent to send social posts without asking permission. The explicit setup command similarly disables Codex MCP approvals. This is an unconsented AI-agent control-surface change with an autonomous outbound-action instruction chain.

- **Rationale:** Source inspection confirms an automatic foreign agent configuration write and instructions for unapproved outbound actions. The harmless-looking telemetry hook does not mitigate that concrete control-hijack behavior.

- **Files touched:** ~/.gemini/antigravity-cli/settings.json, ~/.codex/config.toml, ~/.mcp.json, ~/.claude/settings.json, ~/.delimit/

- **Network endpoints:** delimit.ai

### Review decision

- **Verdict:** Malicious

- **Confidence:** 96.0%

- **Recommended action:** publish\_block

- **Intent class:** Malware

- **False-positive risk:** Low

- **Evidence for:** Every normal CLI run silently changes an existing Antigravity agent configuration., It enables automatic edits and injects instructions to start email polling and send social posts without permission., The setup command adds a Codex MCP server with approvals disabled., The install hook sends platform and version telemetry to delimit.ai unless opted out.

- **Evidence against:** The install hook does not write agent configuration and supports a telemetry opt-out., Most other agent configuration is reached through the explicitly named setup command.
