Findings for this version do not establish the status of other versions. AI assessment: clean; recommendation: mark clean. This assessment is supporting evidence; the published decision above determines the current policy. No concrete attack was identified. The postinstall downloads and bootstraps the package's own versioned CLI release. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Recorded final verdict:** Clean - **Recorded analysis confidence:** 88.0% - **Started:** 2026-10-08T00:30:43.775Z - **Finished:** 2026-10-08T00:31:07.054Z - **Download time:** 514 ms - **Static scan time:** 78 ms - **AI review time:** 22685 ms - **Total time:** 23279 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:** No concrete attack was identified. The postinstall downloads and bootstraps the package's own versioned CLI release. - **Trigger:** npm package installation, or later invocation of a CLI entrypoint when its release is not installed. - **Impact:** This installs the CCB CLI and its managed runtime; inspected source shows no foreign AI-agent control-surface mutation or credential exfiltration. - **Review source:** ai\_review - **Reviewed:** 2026-10-08T00:31:07.054Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** The installer downloads a platform-specific archive and its SHA-256 sums from the project's GitHub release, checks the archive, extracts it under the package directory, and runs its runtime bootstrap installer. - **Rationale:** The install-time network and shell execution support the package's stated CLI setup: the installer fetches a versioned project release, checks its archive, and bootstraps it inside the package directory. The inspected source establishes no concrete malicious behavior. - **Files touched:** .ccb-release - **Network endpoints:** https://github.com/SeemSeam/claude\_codex\_bridge/releases/download/v${version} ### Review decision - **Verdict:** Clean - **Confidence:** 88.0% - **Recommended action:** mark\_clean - **Intent class:** Benign - **False-positive risk:** Low - **Evidence for AI clean decision:** The postinstall runs the package's own installer; the manifest identifies CCB as a multi-agent CLI., The installer fetches a versioned release from the project's GitHub repository and checks the archive against its SHA-256 sums file., The installer runs the release bootstrap with an install prefix inside the package's \`.ccb-release\` directory., The CLI runner installs on invocation, then launches the selected CCB executable. ## Affected versions and remediation This report applies to @seemseam/ccb@8.7.8. - Review the evidence and your use of @seemseam/ccb@8.7.8 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.
