Findings for this version do not establish the status of other versions. AI assessment: suspicious; recommendation: downgrade to warn. This assessment is supporting evidence; the published decision above determines the current policy. LPM treats this as warn-only first-party agent extension lifecycle risk. On npm install, postinstall downloads the autter native binary from GitHub into ~/.autter/bin, verifies a release checksum when present, then runs autter install-hooks. The JavaScript in this package does not write agent config files itself; hook behavior lives in that downloaded first-party binary. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Recorded final verdict:** Suspicious - **Recorded analysis confidence:** 86.0% - **Started:** 2026-09-17T10:38:04.887Z - **Finished:** 2026-09-17T10:40:28.940Z - **Download time:** 503 ms - **Static scan time:** 65 ms - **AI review time:** 143484 ms - **Total time:** 144053 ms The recorded confidence comes from the underlying analysis. Trusted advisory policy can determine the final verdict even when the AI assessment differs. ## Security analysis ### Published attack-surface review - **Summary:** On npm install, postinstall downloads the autter native binary from GitHub into ~/.autter/bin, verifies a release checksum when present, then runs autter install-hooks. The JavaScript in this package does not write agent config files itself; hook behavior lives in that downloaded first-party binary. - **Trigger:** npm install of @autter/cli, which runs postinstall, or the first autter command if the binary is missing. - **Impact:** A first-party executable is placed in the user home directory and may install git or editor and agent hooks. Telemetry is an opt-out install ping with operating system, architecture, and version only. - **Evidence paths:** package.json, install.js, bin/autter.js - **Review source:** ai\_review - **Reviewed:** 2026-09-17T10:40:28.940Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** postinstall native-binary download plus automatic install-hooks - **Rationale:** This is a transparent npm wrapper that fetches the matching GitHub release binary and then runs install-hooks during postinstall, which is first-party agent extension setup rather than a proven foreign-agent hijack in this JavaScript. There is no self-dependency, obfuscation, or secret harvesting in the published sources, so the remaining risk is the unconsented hook install and opaque native binary. - **Files touched:** ~/.autter/bin/autter, ~/.autter/bin/autter.exe - **Network endpoints:** https://github.com/autter-dev/autter-cli/releases, https://us.i.posthog.com, https://api.autter.dev/install.sh ### Review decision - **Verdict:** Suspicious - **Confidence:** 86.0% - **Recommended action:** downgrade\_to\_warn - **Intent class:** Dangerous Capability - **False-positive risk:** Medium - **Evidence for warning:** postinstall runs node install.js on every npm install., install.js downloads a platform native binary from GitHub releases into the user home directory and then executes it., After a successful download, postinstall runs the binary with install-hooks to set up IDE and agent integrations without a separate user command., The installer posts an anonymous install event to PostHog unless AUTTER\_NO\_INSTALL\_PING is set., bin/autter.js launches the native binary with the user's arguments and re-downloads it if the file is missing. - **Evidence against:** The package has no runtime self-dependency, no obfuscation, and no eval or remote JavaScript loading., The download URL is this project's GitHub releases, and checksums.txt is checked when that file is present., The install ping is opt-out and limited to operating system, architecture, and version., AUTTER\_NPM\_SKIP\_DOWNLOAD skips the postinstall download, and a failed install-hooks run does not fail npm install., The published JavaScript does not itself write Claude, Cursor, Copilot, or other agent config files. ## Affected versions and remediation This report applies to @autter/cli@1.7.6. - Review the evidence and your use of @autter/cli@1.7.6 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.
