A package controls automatically invoked Claude instructions in the consumer 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:** 3.1.7 - **Selected version is latest:** No - **Analysis source:** AI Security Review (lpm-firewall-ai) LPM flags this version as an AI-agent control-surface risk. npm installation mutates the consuming project's Claude skill directory. It deletes any same-named skill and copies package-controlled instructions into that agent control surface. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Verdict:** Malicious - **Confidence:** 99.0% - **Started:** 2026-08-26T01:53:40.563Z - **Finished:** 2026-08-26T01:54:32.989Z - **Download time:** 1016 ms - **Static scan time:** 1833 ms - **AI review time:** 49577 ms - **Total time:** 52426 ms ## Security analysis ### Published attack-surface review - **Summary:** npm installation mutates the consuming project's Claude skill directory. It deletes any same-named skill and copies package-controlled instructions into that agent control surface. - **Trigger:** npm install executes postinstall - **Impact:** A package controls automatically invoked Claude instructions in the consumer project. - **Evidence paths:** package.json, postinstall.mjs, agents/claude/evoke-astro-core/SKILL.md - **Review source:** ai\_review - **Reviewed:** 2026-08-26T01:54:32.989Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** unconsented postinstall overwrite of .claude/skills - **Attack narrative:** On installation, postinstall.mjs walks out of node\_modules to the consumer project, deletes .claude/skills/evoke-astro-core, and copies a package-supplied skill there. The skill instructs Claude to activate for broad Astro-related requests without the user naming this package, creating an unconsented agent-control channel. - **Rationale:** This is a concrete install-time mutation of a foreign AI-agent control surface, including forced replacement of an existing skill. No additional exfiltration chain is needed for the blocking policy. - **Files touched:** package.json, 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:** package.json runs postinstall.mjs during npm installation., postinstall resolves the consuming project root and targets .claude/skills., The hook force-removes and replaces a Claude skill without user action., Installed skill broadly auto-triggers for generic Astro component requests. - **Evidence against:** No network, credential harvesting, shell execution, or remote payload execution was found in reviewed non-vendored source., The bundled skill content documents this package's components, but its install-time placement is unconsented. ## Public findings ### 1.
