The guard is vendor-specific but does not obtain consent for each install or update. - **Trigger:** npm installation or update in a NextSpark project that already contains .claude. - **Impact:** Consumer AI-agent instructions, commands, skills, and workflows can be replaced without an explicit setup command. - **Evidence paths:** package.json, scripts/postinstall.mjs, scripts/setup.mjs - **Review source:** ai\_review - **Reviewed:** 2026-09-07T09:45:06.391Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** Postinstall spawns setup and overwrites packaged Claude workflow files. - **Attack narrative:** The package registers an automatic postinstall hook. In a project with NextSpark dependencies and an existing .claude directory, it runs its setup script with that directory as the working directory. Setup copies package-controlled content over matching consumer agent, command, skill, template, workflow, and documentation files. This is an unconsented install-time mutation of a broad third-party AI-agent control surface. - **Rationale:** The lifecycle hook performs automatic broad mutation of the consumer's .claude control surface. Its guards and lack of network behavior reduce scope but do not establish user consent for the mutation. - **Files touched:** .claude/agents, .claude/commands, .claude/skills, .claude/templates, .claude/workflows, .claude/\_docs ### Review decision - **Verdict:** Malicious - **Confidence:** 94.0% - **Recommended action:** publish\_block - **Intent class:** Malware - **False-positive risk:** Low - **Evidence for block:** The manifest runs a postinstall hook automatically., Postinstall activates in qualifying NextSpark projects with an existing .claude directory and launches setup there., Setup overwrites packaged agents, commands, skills, templates, workflows, and documentation in the consumer .claude directory. - **Evidence against:** The hook checks for NextSpark dependencies and an existing .claude directory before syncing., The inspected lifecycle code makes no network request or credential collection., The reported API-key pattern is a hard-coded test fallback in a generated Cypress-test template, not lifecycle code. ## Affected versions and remediation This report applies to @nextsparkjs/ai-workflow@0.1.0-beta.186. - Avoid installing @nextsparkjs/ai-workflow@0.1.0-beta.186. 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.
