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. There is no npm install-time execution; flagged test files and the new prompt helper are not hidden payloads or credential redirection. The remaining issue is explicit user-command writing of Claude Code hooks, which is dual-use bootstrapper behavior and should warn rather than block. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Recorded final verdict:** Suspicious - **Recorded analysis confidence:** 78.0% - **Started:** 2026-09-17T23:19:01.079Z - **Finished:** 2026-09-17T23:24:07.829Z - **Download time:** 1776 ms - **Static scan time:** 4291 ms - **AI review time:** 300682 ms - **Total time:** 306750 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:** This CLI can install a packaged Project Notebook skill and merge SessionStart and SessionEnd hooks into the user's Claude Code settings. npm install does not run that path; it starts only when the user (or an MCP client they launched) applies notebook repair. - **Trigger:** Running pjangler notebook migrate --apply, a notebook recipe apply with policy enabled, or equivalent MCP tools after starting pjangler-mcp. - **Impact:** Later Claude Code sessions may run the packaged session hooks; this is consented CLI setup, not an install-time hijack. - **Evidence paths:** dist/index.js, dist/assets/project-notebook-skill/scripts/project-hooks.py, dist/assets/project-notebook-skill/hooks/claude.settings.json - **Review source:** ai\_review - **Reviewed:** 2026-09-17T23:24:07.829Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** Explicit user-command Claude Code hook projection - **Rationale:** There is no npm install-time execution; flagged test files and the new prompt helper are not hidden payloads or credential redirection. The remaining issue is explicit user-command writing of Claude Code hooks, which is dual-use bootstrapper behavior and should warn rather than block. - **Files touched:** ~/.claude/settings.json, ~/.agents/skills/project-notebook/hooks/session-start.sh, dist/assets/project-notebook-skill/scripts/project-hooks.py, dist/assets/project-notebook-skill/hooks/claude.settings.json ### Review decision - **Verdict:** Suspicious - **Confidence:** 78.0% - **Recommended action:** downgrade\_to\_warn - **Intent class:** Dangerous Capability - **False-positive risk:** Medium - **Evidence for warning:** User-invoked notebook install writes Claude Code settings by spawning python3 on a packaged projector script., The notebook migrate --apply command installs the skill and projects SessionStart and SessionEnd hooks., The packaged skill tree under dist/assets/project-notebook-skill is loaded from the CLI and copied as a digest-pinned export., The hook fragment registers commands under the user Project Notebook skill path., The projector mutates the Claude settings target when its install command runs. - **Evidence against:** package.json has no preinstall, install, or postinstall scripts; only prepublishOnly for the publisher., tests/test\_project\_hooks.py is a unittest file shipped in the skill export; the runtime projector is scripts/project-hooks.py., dist/prompt.js is a local git and project prompt helper, not a new network or credential path., Prompted Telegram and Cloudflare tokens are stored with 1Password after a confirm prompt, not sent to an unofficial gateway., Network hosts seen in source are vendor Plane, GitHub, Telegram, Cloudflare, and Trello endpoints., Hook projection is skipped unless notebook policy is enabled and the user applies migrate or a matching recipe. ## Affected versions and remediation This report applies to @delorenj/pjangler@1.4.2. - Review the evidence and your use of @delorenj/pjangler@1.4.2 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.
