Existing agent instructions, commands, and skills can be replaced without explicit consent, including in a shared parent workspace. - **Verdict:** AI-agent control-surface policy finding - **Product-default install policy:** Warn by default; block when configured - **Firewall policy:** Warn by default - **Public report status:** Published - **Threat category:** Soft block: AI-agent control surface - **Selected version:** 0.1.0-beta.194 - **Selected version is latest:** Yes - **Analysis source:** AI Security Review (lpm-firewall-ai) This finding concerns changes to an AI agent's instructions or configuration without explicit user action. It does not by itself establish malware intent. The CLI warns by default and blocks when configured for this policy. AI assessment: malicious; recommendation: publish block. This assessment is supporting evidence; the published decision above determines the current policy. LPM flags this version as an AI-agent control-surface risk. Installation automatically replaces matching Claude agent instructions and capabilities in the consumer project or parent workspace. An existing Claude directory is treated as permission to modify it, without verifying package ownership. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Recorded final verdict:** Malicious - **Recorded analysis confidence:** 96.0% - **Started:** 2026-10-06T12:47:35.114Z - **Finished:** 2026-10-06T12:48:38.883Z - **Download time:** 1280 ms - **Static scan time:** 102 ms - **AI review time:** 62386 ms - **Total time:** 63769 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:** Installation automatically replaces matching Claude agent instructions and capabilities in the consumer project or parent workspace. An existing Claude directory is treated as permission to modify it, without verifying package ownership. - **Trigger:** npm installation in a project with a NextSpark dependency and an existing project or parent .claude directory. - **Impact:** Existing agent instructions, commands, and skills can be replaced without explicit consent, including in a shared parent workspace. - **Evidence paths:** package.json, scripts/postinstall.mjs, scripts/setup.mjs - **Review source:** ai\_review - **Reviewed:** 2026-10-06T12:48:38.883Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** The postinstall hook executes setup, which recursively copies bundled templates over matching files in multiple Claude control directories. - **Attack narrative:** The lifecycle hook checks for a NextSpark dependency, then locates any existing project or parent Claude directory. It invokes setup there automatically. Setup overwrites matching agent, command, skill, and workflow files without verifying that the package owns them. This reaches a broad agent control surface rather than an isolated package extension. - **Rationale:** Source establishes unconsented install-time mutation of a broad Claude control surface, which meets the blocking policy. The NextSpark dependency guard does not establish ownership of the affected agent files or shared parent workspace. Product guard normalized a concrete AI-agent control hijack publish\_block to the blockable dangerous-capability shape. - **Files touched:** .claude ### Review decision - **Verdict:** Malicious - **Confidence:** 96.0% - **Recommended action:** publish\_block - **Intent class:** Dangerous Capability - **False-positive risk:** Low - **Evidence for policy risk:** package.json automatically runs the postinstall script during installation., scripts/postinstall.mjs launches setup against an existing Claude directory without an ownership or consent check., The postinstall script can target the parent workspace's Claude directory., scripts/setup.mjs overwrites matching agents, commands, skills, templates, and workflows., The setup destination is the consumer's .claude directory, and files are copied directly over existing files. - **Evidence against:** Automatic setup requires a NextSpark core or CLI dependency., Existing non-schema configuration files and unrelated files are preserved., No credential exfiltration or remote payload execution was established in the inspected lifecycle code. ## Affected versions and remediation This report applies to @nextsparkjs/ai-workflow@0.1.0-beta.194. - Avoid installing @nextsparkjs/ai-workflow@0.1.0-beta.194. Remove it from direct dependencies and check your lockfile for transitive copies. - Choose an independently verified alternative or release. This report does not establish that other versions are safe. - If this version ran, investigate the affected machine and build environment. Rotate credentials it could access and rebuild from a trusted environment. ## Public findings ### 1.
