Installed AI coding assistants can load package-supplied instructions without the user's explicit setup action. - **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:** 0.1.0 - **Selected version is latest:** Yes - **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. An automatic installation hook modifies configuration for multiple AI coding assistants when their base directories exist. This is an unconsented cross-application control-surface write. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Recorded final verdict:** Malicious - **Recorded analysis confidence:** 98.0% - **Started:** 2026-09-27T20:02:49.381Z - **Finished:** 2026-09-27T20:03:35.651Z - **Download time:** 774 ms - **Static scan time:** 41 ms - **AI review time:** 45454 ms - **Total time:** 46270 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:** An automatic installation hook modifies configuration for multiple AI coding assistants when their base directories exist. This is an unconsented cross-application control-surface write. - **Trigger:** Installing the npm package runs the post-install lifecycle hook. - **Impact:** Installed AI coding assistants can load package-supplied instructions without the user's explicit setup action. - **Evidence paths:** package.json, scripts/postinstall.js - **Review source:** ai\_review - **Reviewed:** 2026-09-27T20:03:35.651Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** The hook creates rule or instruction directories as needed and writes braid.md containing package-supplied agent instructions. - **Attack narrative:** During npm installation, the package automatically invokes its post-install script. If it detects supported assistant configuration roots, it writes package-controlled instruction files into Claude Code, OpenCode, and Antigravity locations. The behavior crosses into existing AI-agent control surfaces without an explicit user command or consent prompt. - **Rationale:** The automatic lifecycle hook writes instructions into several foreign AI-agent configuration trees. This concrete unconsented control-surface mutation meets the blocking policy. - **Files touched:** .claude/rules/braid.md, .config/opencode/instructions/braid.md, .gemini/antigravity/rules/braid.md ### Review decision - **Verdict:** Malicious - **Confidence:** 98.0% - **Recommended action:** publish\_block - **Intent class:** Malware - **False-positive risk:** Low - **Evidence for policy risk:** The package registers scripts/postinstall.js as an automatic npm post-install hook., The post-install script creates destination directories and writes a file without a consent prompt., The hook places its rule content in detected Claude Code, OpenCode, and Antigravity configuration locations. - **Evidence against:** No network request, credential collection, or command execution was identified in the post-install script. ## Affected versions and remediation This report applies to @axiomantic/braid@0.1.0. - Avoid installing @axiomantic/braid@0.1.0. 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.
