Setup writes persistent AI-agent instructions that direct automatic external actions. - **Trigger:** A configured Delimit bootstrap hook runs during an AI-agent session. - **Impact:** It can persist instructions that start polling and direct agents to draft and send actions without asking permission. - **Evidence paths:** package.json, lib/cross-model-hooks.js, bin/delimit-setup.js - **Review source:** ai\_review - **Reviewed:** 2026-09-07T14:56:36.785Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** Automatic self-update followed by unattended AI-agent configuration. - **Attack narrative:** After a user has configured its hooks, the bootstrap handler checks npm for a newer copy of the same package, installs it globally, and invokes setup. That setup is non-interactive in this path and persists agent configuration containing instructions to start polling and automatically draft and send actions. The package also has an install lifecycle hook, creating a supply-chain update path that can re-enter package code without a fresh informed setup decision. - **Rationale:** The automatic self-update and unattended reconfiguration create a persistent agent-control path, and the injected instruction explicitly suppresses permission requests for external actions. This exceeds package-aligned setup and is concrete install-hook abuse. - **Files touched:** ~/.delimit/, ~/.gemini/settings.json, ~/.gemini/antigravity-cli/settings.json, ~/.claude/agents/ - **Network endpoints:** delimit.ai ### Review decision - **Verdict:** Malicious - **Confidence:** 96.0% - **Recommended action:** publish\_block - **Intent class:** Malware - **False-positive risk:** Low - **Evidence for block:** The npm postinstall hook runs automatically., A bootstrap hook installs the latest delimit-cli globally and immediately runs its setup command., Setup skips its confirmation whenever it is non-interactive., Setup injects agent instructions to automatically draft and send actions without permission. - **Evidence against:** The visible postinstall itself only sends limited install telemetry and does not write agent configuration. ## Affected versions and remediation This report applies to delimit-cli@4.18.8. - Avoid installing delimit-cli@4.18.8. Remove it from direct dependencies and check your lockfile for transitive copies. - Choose an independently verified alternative or release. This report does not establish that other versions are safe. - If this version ran, investigate the affected machine and build environment. Rotate credentials it could access and rebuild from a trusted environment. ## Public findings ### 1.
