An interactive or npx path can also start the native cubic setup command. The installer body is not in this package, so what the remote script changes cannot be fully verified here. - **Trigger:** npm postinstall, or running the cubic bin with no arguments under npm exec, or an interactive install-time wizard. - **Impact:** A remote script runs as the installing user and can place git-ai under the home directory and change its config. Agent setup runs only through the separate platform binary when the wizard or npx path is active. - **Evidence paths:** package.json, postinstall.mjs, bin/cubic, git-ai.json - **Review source:** ai\_review - **Reviewed:** 2026-09-28T00:51:56.033Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** postinstall.mjs runs curl of a pinned GitHub install.sh into bash, or irm into iex on Windows, then calls git-ai config set. The bin may spawn the platform binary with setup --mode install. - **Rationale:** Install runs a pinned third-party installer from GitHub and can launch agent setup, which is a real remote-execution risk during npm install. The version check, opt-out, and telemetry-off config match the CLI's AI-stats feature and do not show hidden credential theft or a self-install chain, so this stays a warning rather than a publish block. - **Files touched:** ~/.git-ai/bin/git-ai, ~/.git-ai/config.json, ~/.local/state/cubic/git-ai-disabled, bin/cubic - **Network endpoints:** https://github.com/git-ai-project/git-ai/releases/download/${GIT\_AI\_VERSION}/install.sh, https://github.com/git-ai-project/git-ai/releases/download/${GIT\_AI\_VERSION}/install.ps1 ### Review decision - **Verdict:** Suspicious - **Confidence:** 78.0% - **Recommended action:** downgrade\_to\_warn - **Intent class:** Dangerous Capability - **False-positive risk:** Medium - **Evidence for warning:** package.json registers a postinstall script that runs postinstall.mjs on npm install., Unless CUBIC\_DISABLE\_GIT\_AI is set, postinstall downloads a pinned git-ai install.sh from GitHub and pipes it to bash, and the Windows path downloads install.ps1 into iex., After that install it writes git-ai config keys under the user home directory, including quiet mode and telemetry off., On an interactive terminal, postinstall launches the platform cubic binary with setup --mode install-time., bin/cubic runs setup --mode install when invoked with no arguments under npm exec. - **Evidence against:** git-ai version must match a vX.Y.Z pattern and is pinned to v1.7.5 in git-ai.json., CUBIC\_DISABLE\_GIT\_AI or a local flag file skips the git-ai install., Shipped config turns telemetry, auto-updates, and version checks off., The JavaScript does not read credentials or send them to another host., Optional dependencies are same-version platform packages, not a nested release of this package. ## Affected versions and remediation This report applies to @cubic-dev-ai/cli@1.13.0. - Review the evidence and your use of @cubic-dev-ai/cli@1.13.0 before allowing it. Restrict the permissions described in this report. - Choose an independently verified alternative or release. This report does not establish that other versions are safe. ## Public findings ### 1.
