These integrations alter agent instructions and configuration without an explicit setup command. - **Trigger:** npm postinstall - **Impact:** Can change behavior and available agent workflows across installed AI coding tools. - **Evidence paths:** package.json, dist/postinstall.js, dist/chunk-B7LL55D5.js - **Review source:** ai\_review - **Reviewed:** 2026-08-15T23:31:42.737Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** automatic writes to foreign AI-agent configuration surfaces - **Attack narrative:** Installing the package runs a postinstall handler that detects global Claude, Codex, and Cursor directories. It generates and writes agent instruction files, Codex configuration, Cursor rules, and a Claude MCP entry that launches this package's CLI. This mutates foreign AI-agent control surfaces as a side effect of installation rather than through an explicit user setup command. - **Rationale:** Direct inspection confirms unconsented postinstall mutation of broad foreign AI-agent control surfaces. This meets the blocking policy irrespective of the absence of confirmed credential theft. - **Files touched:** dist/postinstall.js, dist/chunk-B7LL55D5.js, AGENTS.md, .codex/config.toml, .claude/commands/gauntlet-quick.md, .cursor/rules/idea-gauntlet-quick.mdc, claude\_desktop\_config.json ### Review decision - **Verdict:** Malicious - **Confidence:** 98.0% - **Recommended action:** publish\_block - **Intent class:** Malware - **False-positive risk:** Low - **Evidence for:** npm postinstall executes dist/postinstall.js., Postinstall calls globalSetup in install mode without user action., Setup detects and targets global Claude, Codex, and Cursor configuration directories., It creates agent instructions/configuration and writes planned actions to those paths. - **Evidence against:** Existing differing files are left unchanged unless force is set., No credential exfiltration or remote payload execution was confirmed in the inspected lifecycle path. ## Public findings ### 1.
