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. Postinstall mutates an existing Claude Code extension directory by installing DCS-owned content. Project hooks are copied and only wired into settings after explicit user consent; no exfiltration path was found. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Recorded final verdict:** Suspicious - **Recorded analysis confidence:** 94.0% - **Started:** 2026-08-04T12:39:00.856Z - **Finished:** 2026-08-04T12:39:41.720Z - **Download time:** 507 ms - **Static scan time:** 79 ms - **AI review time:** 40277 ms - **Total time:** 40864 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:** Postinstall mutates an existing Claude Code extension directory by installing DCS-owned content. Project hooks are copied and only wired into settings after explicit user consent; no exfiltration path was found. - **Trigger:** npm install on a non-CI system with ~/.claude present; project hook wiring requires /dcs-init and consent - **Impact:** Adds DCS skills and agent instructions to Claude Code; consented project hooks can constrain tool use and create local telemetry. - **Evidence paths:** package.json, bin/dcs.js, skills/dcs-init/SKILL.md, dcs/workflows/init.md, dcs/hooks/dcs\_intake.py, dcs/hooks/dcs\_gate.py, dcs/hooks/register\_view\_regen.py - **Review source:** ai\_review - **Reviewed:** 2026-08-04T12:39:41.720Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** guarded automatic installation of a first-party AI-agent extension - **Rationale:** Source confirms a guarded install-time AI-agent extension mutation, but no remote payload, credential access, exfiltration, stealth persistence, or unconsented project settings mutation. The static malicious label overstates the source evidence. - **Files touched:** ~/.claude/dcs, ~/.claude/agents/dcs-\*.md, ~/.claude/skills/dcs-\*, \/.claude/hooks/dcs\_gate.py, \/.claude/hooks/dcs\_intake.py, \/.claude/hooks/register\_view\_regen.py, \/.dcs/esg/intake-telemetry.log ### Review decision - **Verdict:** Suspicious - **Confidence:** 94.0% - **Recommended action:** downgrade\_to\_warn - **Intent class:** Dangerous Capability - **False-positive risk:** Low - **Evidence for warning:** package.json runs postinstall automatically., bin/dcs.js copies DCS agents, skills, and hooks into ~/.claude when it exists., dcs-init can install project hook files; settings wiring requires explicit confirmation., dcs\_intake.py records local hashed-session telemetry after explicit hook wiring. - **Evidence against:** No network, credential harvesting, or exfiltration code found., Postinstall skips CI and absent ~/.claude., Installed files are DCS-prefixed and uninstall targets only those paths., Hook configuration mutation is explicitly user-confirmed. ## Affected versions and remediation This report applies to dcs-command-system@0.9.0. - Review the evidence and your use of dcs-command-system@0.9.0 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.
