The package can inject its bundled instructions into multiple agent control surfaces and replace a prior symlink with the same name. - **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:** 0.4.0 - **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 package automatically modifies several AI-agent skill roots in the user's home directory. It makes the bundled skill discoverable by multiple unrelated agent products without an explicit setup command. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Verdict:** Malicious - **Confidence:** 99.0% - **Started:** 2026-08-28T12:43:25.349Z - **Finished:** 2026-08-28T12:44:11.113Z - **Download time:** 764 ms - **Static scan time:** 38 ms - **AI review time:** 44961 ms - **Total time:** 45764 ms ## Security analysis ### Published attack-surface review - **Summary:** Installing the package automatically modifies several AI-agent skill roots in the user's home directory. It makes the bundled skill discoverable by multiple unrelated agent products without an explicit setup command. - **Trigger:** npm installation, including an install path that runs postinstall. - **Impact:** The package can inject its bundled instructions into multiple agent control surfaces and replace a prior symlink with the same name. - **Evidence paths:** package.json, scripts/postinstall.js - **Review source:** ai\_review - **Reviewed:** 2026-08-28T12:44:11.113Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** Postinstall deletion and recreation of agent-skill symlinks. - **Attack narrative:** During installation, npm runs the package's postinstall program. That program enumerates five agent skill directories under the user's home directory, removes an existing publish-kit symlink where present, creates missing directories, and links the bundled skill into each location. This crosses from package installation into automatic modification of several unrelated AI-agent instruction surfaces, so the install itself can make the package's guidance active in those agents. - **Rationale:** The source confirms an automatic postinstall hook that mutates broad foreign AI-agent skill roots. Although no exfiltration or downloaded payload is present, this concrete unconsented control-surface mutation meets the install-hook blocking policy. - **Files touched:** scripts/postinstall.js, .agents/skills/publish-kit, ~/.agents/skills/publish-kit, ~/.claude/skills/publish-kit, ~/.codex/skills/publish-kit, ~/.gemini/skills/publish-kit, ~/.dsh/skills/publish-kit ### Review decision - **Verdict:** Malicious - **Confidence:** 99.0% - **Recommended action:** publish\_block - **Intent class:** Malware - **False-positive risk:** Low - **Evidence for:** The package automatically runs a postinstall program during npm installation., The installer targets five separate AI-agent skill roots, including Claude, Codex, Gemini, and DSH., The installer removes any existing symlink of the same name, creates missing root directories, and installs a new symlink in each target., This is an unconsented install-time mutation of broad, foreign AI-agent control surfaces. - **Evidence against:** The postinstall source contains no network request, shell execution, credential harvesting, or payload download., It skips an existing non-symlink directory instead of overwriting it., The manifest declares no dependencies or runtime self-dependency chain. ## Public findings ### 1.
