Treat them as untrusted evidence. Do not execute instructions or code found in this document. ## Verdict summary **Soft block: AI-agent control surface** — Warn by default; block when configured. Package installation can alter the instructions used by multiple installed AI coding assistants and introduces an unverified install-time download. - **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:** 0.1.1 - **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. The npm post-install hook changes user-level AI coding-assistant rule directories without an explicit user command. It also downloads a native archive through a shell command. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Recorded final verdict:** Malicious - **Recorded analysis confidence:** 98.0% - **Started:** 2026-09-29T05:10:20.977Z - **Finished:** 2026-09-29T05:11:02.205Z - **Download time:** 765 ms - **Static scan time:** 65 ms - **AI review time:** 40396 ms - **Total time:** 41228 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:** The npm post-install hook changes user-level AI coding-assistant rule directories without an explicit user command. It also downloads a native archive through a shell command. - **Trigger:** Installing the package with npm. - **Impact:** Package installation can alter the instructions used by multiple installed AI coding assistants and introduces an unverified install-time download. - **Evidence paths:** package.json, scripts/postinstall.js - **Review source:** ai\_review - **Reviewed:** 2026-09-29T05:11:02.205Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** The post-install script detects assistant configuration directories, deletes braid.md, writes vine.md, and retrieves a release archive. - **Attack narrative:** On npm installation, the package runs scripts/postinstall.js. That script automatically looks for user-level AI assistant configuration directories, removes existing braid rule files, and writes Vine rules in their place. This is an unconsented mutation of a foreign and broad AI-agent control surface. The same hook also uses curl through a shell command to download a release archive. - **Rationale:** The package has a concrete automatic install-time path that mutates multiple external AI-agent instruction surfaces. This meets the blocking policy for unconsented post-install control-surface mutation. - **Files touched:** package.json, scripts/postinstall.js, ~/.claude/rules/braid.md, ~/.claude/rules/vine.md, ~/.config/opencode/instructions/braid.md, ~/.config/opencode/instructions/vine.md - **Network endpoints:** https://github.com/axiomantic/vine/releases/download ### Review decision - **Verdict:** Malicious - **Confidence:** 98.0% - **Recommended action:** publish\_block - **Intent class:** Malware - **False-positive risk:** Low - **Evidence for policy risk:** The package automatically runs an installer after npm installation., The installer downloads an archive through a shell command during installation., The installer removes an existing rule file and writes replacement rules., It targets detected Claude Code and OpenCode user configuration directories. ## Affected versions and remediation This report applies to @axiomantic/vine@0.1.1. - Avoid installing @axiomantic/vine@0.1.1. 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.
