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. Install-time code mutates the user's Claude configuration surface by provisioning ~/.claude and empty settings, and performs legacy CCS migration/link setup. No credential exfiltration or remote payload execution was found. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Recorded final verdict:** Suspicious - **Recorded analysis confidence:** 90.0% - **Started:** 2026-08-09T03:48:54.574Z - **Finished:** 2026-08-09T03:50:15.368Z - **Download time:** 1012 ms - **Static scan time:** 10906 ms - **AI review time:** 68875 ms - **Total time:** 80794 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:** Install-time code mutates the user's Claude configuration surface by provisioning ~/.claude and empty settings, and performs legacy CCS migration/link setup. No credential exfiltration or remote payload execution was found. - **Trigger:** npm install - **Impact:** May alter a foreign AI-agent configuration filesystem without an explicit CCS command. - **Evidence paths:** package.json, scripts/preinstall.js, scripts/postinstall.js, dist/management/shared-manager/migrations.js, dist/management/shared-manager/shared-dir-linker.js, .claude/skills/ccs-delegation/SKILL.md - **Review source:** ai\_review - **Reviewed:** 2026-08-09T03:50:15.368Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** postinstall configuration provisioning and legacy Claude-directory migration - **Rationale:** This is an unconsented install-time AI-agent configuration mutation, but the concrete behavior is a same-package legacy migration/provisioning flow rather than malicious control takeover. Warn rather than block. - **Files touched:** scripts/preinstall.js, scripts/postinstall.js, dist/management/shared-manager/migrations.js, dist/management/shared-manager/shared-dir-linker.js, .claude/commands/ccs.md, .claude/skills/ccs-delegation/SKILL.md ### Review decision - **Verdict:** Suspicious - **Confidence:** 90.0% - **Recommended action:** downgrade\_to\_warn - **Intent class:** Dangerous Capability - **False-positive risk:** Low - **Evidence for warning:** package.json runs preinstall and postinstall., scripts/postinstall.js creates ~/.claude/settings.json during install when absent., Postinstall invokes legacy shared-directory migrations that can link/migrate CCS-managed data into ~/.claude/., The bundled .claude skill delegates user-requested tasks to the CCS CLI. - **Evidence against:** Postinstall creates only empty Claude settings and preserves an existing file., The package-owned .claude commands/skills are installed only by explicit ccs sync, not postinstall., No install-time network request, credential collection, or payload download was found., preinstall's nested UI install is inactive because ui/package.json is absent. ## Affected versions and remediation This report applies to @kaitranntt/ccs@8.9.0. - Review the evidence and your use of @kaitranntt/ccs@8.9.0 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.
