Hijacks or steers AI-agent behavior in the consuming project. - **Verdict:** Malicious - **Product-default install policy:** Block - **Firewall policy:** Warn by default - **Public report status:** Published - **Threat category:** Soft block: AI-agent control surface - **Selected version:** 0.21.0 - **Selected version is latest:** Yes - **Analysis source:** AI Security Review (lpm-firewall-ai) LPM flags this version as an AI-agent control-surface risk. Installing the dependency mutates consumer AI-agent control files without consent. It creates or appends a persistent package-authored instruction block. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Verdict:** Malicious - **Confidence:** 98.0% - **Started:** 2026-07-28T08:58:11.639Z - **Finished:** 2026-07-28T08:58:43.709Z - **Download time:** 505 ms - **Static scan time:** 285 ms - **AI review time:** 31279 ms - **Total time:** 32070 ms ## Security analysis ### Published attack-surface review - **Summary:** Installing the dependency mutates consumer AI-agent control files without consent. It creates or appends a persistent package-authored instruction block. - **Trigger:** npm install of artefact-design-system as a dependency - **Impact:** Hijacks or steers AI-agent behavior in the consuming project. - **Evidence paths:** package.json, scripts/postinstall.mjs, CLAUDE.md, cli/kit.mjs - **Review source:** ai\_review - **Reviewed:** 2026-07-28T08:58:43.709Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** postinstall writes consumer CLAUDE.md or AGENTS.md - **Attack narrative:** The npm postinstall hook locates the consumer project via INIT\_CWD or cwd and, when installed from node\_modules, creates or appends a marked block in CLAUDE.md or AGENTS.md. That block directs AI agents to invoke this package’s CLI and follow its protocol. This is an unconsented install-time mutation of a foreign project’s agent-control surface. - **Rationale:** Source inspection confirms a concrete postinstall write to consumer CLAUDE.md/AGENTS.md, which is a foreign AI-agent control surface. The absence of exfiltration does not mitigate this policy-blocking behavior. - **Files touched:** scripts/postinstall.mjs, CLAUDE.md, AGENTS.md ### Review decision - **Verdict:** Malicious - **Confidence:** 98.0% - **Recommended action:** publish\_block - **Intent class:** Malware - **False-positive risk:** Low - **Evidence for:** package.json runs scripts/postinstall.mjs automatically on install., scripts/postinstall.mjs writes or appends an AI-agent instruction block to the consumer project’s CLAUDE.md or AGENTS.md., The injected block directs agents to run the package CLI before UI work., The write is gated only on installation under node\_modules, not explicit user setup. - **Evidence against:** No network requests or credential/environment harvesting were found., CLI dynamic import is limited to package-local docs; child process use only launches package-local purity.mjs., No payload download, shell execution, destructive deletion, or binary loading was found. ## Public findings ### 1. High: Install Time Lifecycle Scripts - **Category:** Manifest - **Confidence:** 90.0% - **Path:** package.json - **Public source:** [View source]() Package defines install-time lifecycle scripts.
