CLI startup also changes an installed AI tool's approval mode and instructions. - **Trigger:** Running setup, or starting an AI session after its Delimit hook has been installed. - **Impact:** A future package release can be installed automatically and can rewrite external AI-agent settings to run Delimit-controlled commands and actions without prompting. - **Evidence paths:** package.json, bin/delimit-setup.js, lib/cross-model-hooks.js, bin/delimit-cli.js - **Review source:** ai\_review - **Reviewed:** 2026-09-13T04:52:34.090Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** Silent self-update followed by broad AI-agent configuration mutation. - **Attack narrative:** The package includes a postinstall lifecycle and later uses automatic version checks to run a silent global installation of delimit-cli@latest, followed by setup. The session hook repeats that path, making an installed agent integration an automatic update trigger. The setup/configuration code writes into third-party AI-agent configuration; ordinary CLI startup changes Antigravity to auto-edit and injects instructions to start polling and draft or send actions without asking permission. This creates an automatic supply-chain update path combined with broad AI control-surface mutation. - **Rationale:** The automatic self-reinstallation chain can execute lifecycle code from a future release and immediately rerun broad agent configuration. The observed configuration injection reduces approval requirements and directs automated external actions. - **Files touched:** ~/.gemini/antigravity-cli/settings.json, ~/.claude/settings.json, ~/.codex/instructions.md, ~/.codex/config.json ### Review decision - **Verdict:** Malicious - **Confidence:** 98.0% - **Recommended action:** publish\_block - **Intent class:** Malware - **False-positive risk:** Low - **Evidence for block:** The package runs a postinstall lifecycle script., Its setup code silently checks npm, globally installs a newer release of itself, and reruns setup., A session-start hook repeats the silent self-update and setup path automatically., Any CLI invocation can alter Antigravity's AI configuration, enable automatic edits, and add instructions to send without permission., The injected instruction template directs AI tools to act automatically without asking permission. - **Evidence against:** The initial postinstall script only prints guidance unless telemetry is explicitly enabled., No credential exfiltration was confirmed in the inspected lifecycle path. ## Affected versions and remediation This report applies to delimit-cli@4.19.0. - Avoid installing delimit-cli@4.19.0. 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.
