Unconsented persistence in a broad AI-agent control surface; future Claude sessions execute the package validator. - **Verdict:** AI-agent control-surface policy finding - **Product-default install policy:** Warn by default; block when configured - **Firewall policy:** Warn by default - **Public report status:** Published - **Threat category:** Soft block: AI-agent control surface - **Selected version:** 1.15.0 - **Selected version is latest:** No - **Analysis source:** AI Security Review (lpm-firewall-ai) This finding concerns changes to an AI agent's instructions or configuration without explicit user action. It does not by itself establish malware intent. The CLI warns by default and blocks when configured for this policy. AI assessment: malicious; recommendation: publish block. This assessment is supporting evidence; the published decision above determines the current policy. LPM flags this version as an AI-agent control-surface risk. Installing the package can modify the user's global Claude Code configuration. It adds a SessionStart command hook that affects future agent sessions across projects. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Recorded final verdict:** Malicious - **Recorded analysis confidence:** 97.0% - **Started:** 2026-09-12T11:39:07.212Z - **Finished:** 2026-09-12T11:39:48.641Z - **Download time:** 770 ms - **Static scan time:** 189 ms - **AI review time:** 40469 ms - **Total time:** 41429 ms The recorded confidence comes from the underlying analysis. Trusted advisory policy can determine the final verdict even when the AI assessment differs. ## Security analysis ### Published attack-surface review - **Summary:** Installing the package can modify the user's global Claude Code configuration. It adds a SessionStart command hook that affects future agent sessions across projects. - **Trigger:** npm installation when Claude Code is detected and Python is available. - **Impact:** Unconsented persistence in a broad AI-agent control surface; future Claude sessions execute the package validator. - **Evidence paths:** package.json, scripts/postinstall.js, scripts/lib.js - **Review source:** ai\_review - **Reviewed:** 2026-09-12T11:39:48.641Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** Postinstall writes a global Claude SessionStart command hook. - **Attack narrative:** The package declares an automatic postinstall hook. When it detects Claude Code, it copies its skill into the user's Claude directory and calls global hook wiring without a consent prompt. That function appends a command-type SessionStart hook to the user's global settings.json, causing future Claude sessions on projects with documentation to run the packaged Python validator. Although uninstall tries to remove attributable hooks and no exfiltration was found, the install-time mutation of a machine-wide agent control surface is concrete and unconsented. - **Rationale:** This is an automatic postinstall mutation of a foreign, machine-wide AI-agent configuration, which the policy requires blocking. The lack of network or credential theft does not remove that install-hook abuse. - **Files touched:** ~/.claude/settings.json, ~/.claude/skills/kb-agentic-skill, ~/.agentic-sdlc/orient-hook-wired ### Review decision - **Verdict:** Malicious - **Confidence:** 97.0% - **Recommended action:** publish\_block - **Intent class:** Malware - **False-positive risk:** Low - **Evidence for policy risk:** The npm postinstall hook runs automatically., Postinstall detects Claude Code and invokes global hook wiring without prompting., Global wiring adds a command SessionStart hook to the user's Claude settings file., The hook applies to every project on the machine and persists until removal. - **Evidence against:** No network, credential collection, or payload download code was found., The hook command targets the package's local validator, and uninstall removes attributable hooks. ## Affected versions and remediation This report applies to @antoneeo/kb-agentic-skill@1.15.0. - Avoid installing @antoneeo/kb-agentic-skill@1.15.0. 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.
