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. An automatic postinstall can update package-managed files in an existing consumer .claude directory. The behavior is guarded for NextSpark projects but changes an AI-agent control surface without a per-update command. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Recorded final verdict:** Suspicious - **Recorded analysis confidence:** 90.0% - **Started:** 2026-09-15T16:46:54.620Z - **Finished:** 2026-09-15T16:47:56.010Z - **Download time:** 1026 ms - **Static scan time:** 119 ms - **AI review time:** 60244 ms - **Total time:** 61390 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:** An automatic postinstall can update package-managed files in an existing consumer .claude directory. The behavior is guarded for NextSpark projects but changes an AI-agent control surface without a per-update command. - **Trigger:** Installing or updating the package in a qualifying NextSpark project with .claude already present. - **Impact:** Package updates can replace managed agent instructions, commands, skills, templates, workflows, and schemas. - **Evidence paths:** package.json, scripts/postinstall.mjs, scripts/setup.mjs - **Review source:** ai\_review - **Reviewed:** 2026-09-15T16:47:56.010Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** Guarded postinstall copy of package-supplied AI workflow files. - **Rationale:** The package has a real automatic AI-agent extension update surface, so it warrants a warning. Source inspection found no concrete malicious payload, exfiltration, network activity, or broad unguarded mutation. - **Files touched:** package.json, scripts/postinstall.mjs, scripts/setup.mjs, consumer package.json, .claude/agents/\*\*, .claude/commands/\*\*, .claude/skills/\*\*, .claude/templates/\*\*, .claude/workflows/\*\*, .claude/\_docs/\*\*, .claude/config/\*.schema.json ### Review decision - **Verdict:** Suspicious - **Confidence:** 90.0% - **Recommended action:** downgrade\_to\_warn - **Intent class:** Dangerous Capability - **False-positive risk:** Low - **Evidence for warning:** The package registers an automatic postinstall hook., On qualifying NextSpark projects with an existing .claude directory, postinstall launches the setup script., Setup overwrites package-managed agent, command, skill, template, workflow, and documentation files in the consumer AI-agent directory. - **Evidence against:** The hook is gated on a NextSpark dependency and an existing .claude directory., No network, credential collection, or secret exfiltration was found in the install path., The manifest has no dependencies, including no runtime dependency on another release of itself. ## Affected versions and remediation This report applies to @nextsparkjs/ai-workflow@0.1.0-beta.189. - Review the evidence and your use of @nextsparkjs/ai-workflow@0.1.0-beta.189 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.
