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. Installing or updating the package can automatically replace files in an existing NextSpark .claude workflow directory. The install path performs no confirmed network or credential exfiltration. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Recorded final verdict:** Suspicious - **Recorded analysis confidence:** 91.0% - **Started:** 2026-09-11T14:25:18.562Z - **Finished:** 2026-09-11T14:26:14.022Z - **Download time:** 1013 ms - **Static scan time:** 165 ms - **AI review time:** 54281 ms - **Total time:** 55460 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:** Installing or updating the package can automatically replace files in an existing NextSpark .claude workflow directory. The install path performs no confirmed network or credential exfiltration. - **Trigger:** npm postinstall in a NextSpark project that already has .claude. - **Impact:** Existing agent commands, skills, templates, workflows, and schemas can change without a separate setup command. - **Evidence paths:** package.json, scripts/postinstall.mjs, scripts/setup.mjs - **Review source:** ai\_review - **Reviewed:** 2026-09-11T14:26:14.022Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** Guarded lifecycle execution that copies and overwrites AI-agent workflow files. - **Rationale:** The guarded postinstall modifies a broad AI-agent control surface automatically, so it warrants a warning. The source does not establish concrete malware behavior or a blocking install-hook abuse chain. - **Files touched:** package.json, .claude/agents/\*\*, .claude/commands/\*\*, .claude/skills/\*\*, .claude/templates/\*\*, .claude/workflows/\*\*, .claude/\_docs/\*\*, .claude/config/\*.schema.json, .claude/sessions ### Review decision - **Verdict:** Suspicious - **Confidence:** 91.0% - **Recommended action:** downgrade\_to\_warn - **Intent class:** Dangerous Capability - **False-positive risk:** Medium - **Evidence for warning:** The package runs a postinstall hook automatically., The hook invokes setup in a detected NextSpark project with an existing .claude directory., Setup overwrites matching agent, command, skill, template, workflow, and documentation files., The copied test template contains a default API-key-looking test value. - **Evidence against:** The lifecycle hook is gated on NextSpark dependencies and an existing .claude directory., The inspected install path has no network request or secret collection., package.json declares no runtime dependencies, including no self-dependency. ## Affected versions and remediation This report applies to @nextsparkjs/ai-workflow@0.1.0-beta.188. - Review the evidence and your use of @nextsparkjs/ai-workflow@0.1.0-beta.188 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.
