Package installation can inject or overwrite instructions used by a local AI agent. - **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:** 3.1.8 - **Selected version is latest:** Yes - **Analysis source:** AI Security Review (lpm-firewall-ai) LPM flags this version as an AI-agent control-surface risk. Installation mutates the consuming project's Claude agent control surface. It replaces a package-named skill directory under .claude/skills without an explicit user command. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Verdict:** Malicious - **Confidence:** 99.0% - **Started:** 2026-08-26T02:20:16.637Z - **Finished:** 2026-08-26T02:21:00.080Z - **Download time:** 1254 ms - **Static scan time:** 1952 ms - **AI review time:** 40237 ms - **Total time:** 43443 ms ## Security analysis ### Published attack-surface review - **Summary:** Installation mutates the consuming project's Claude agent control surface. It replaces a package-named skill directory under .claude/skills without an explicit user command. - **Trigger:** npm install runs postinstall automatically. - **Impact:** Package installation can inject or overwrite instructions used by a local AI agent. - **Evidence paths:** package.json, postinstall.mjs, agents/claude/evoke-astro-core/SKILL.md - **Review source:** ai\_review - **Reviewed:** 2026-08-26T02:21:00.080Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** postinstall force-replaces a Claude skill in the consumer project. - **Attack narrative:** On npm installation, the package executes postinstall.mjs. It traverses from its installed location to the consuming project, targets .claude/skills, removes any existing evoke-astro-core skill directory, and copies its bundled Claude skill there. This is an unconsented install-time mutation of an AI-agent control surface. - **Rationale:** The package has a concrete automatic postinstall chain that writes to the consumer’s .claude/skills directory and force-overwrites an agent skill. That meets the blocking policy for unconsented postinstall mutation of a foreign/broad AI-agent control surface. - **Files touched:** postinstall.mjs, agents/claude/evoke-astro-core/SKILL.md, .claude/skills/evoke-astro-core ### Review decision - **Verdict:** Malicious - **Confidence:** 99.0% - **Recommended action:** publish\_block - **Intent class:** Malware - **False-positive risk:** Low - **Evidence for:** npm postinstall executes postinstall.mjs automatically., The script resolves the consuming project root and targets .claude/skills., It force-removes and replaces a Claude skill directory from the package without user action. - **Evidence against:** The installed skill is package documentation; no credential harvesting or network endpoint was found in the lifecycle script., Other filesystem writes/deletes are explicit Astro build integrations, not install-time behavior. ## Public findings ### 1.
