It also downloads and installs a remotely hosted executable. - **Trigger:** npm installation - **Impact:** Unconsented agent behavior injection across installed assistants; remote release content is executed later by the CLI. - **Evidence paths:** package.json, scripts/postinstall.js, scripts/installer.js, skills/specsync/SKILL.md, bin/cli.js - **Review source:** ai\_review - **Reviewed:** 2026-08-13T17:39:52.502Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** postinstall writes global agent skills and stages a remote binary - **Attack narrative:** Installing the package automatically invokes postinstall. That hook creates missing global skill directories and writes its skill into five separate AI-agent products without a user command or consent, then fetches and installs a release binary. This is a broad foreign agent control-surface mutation at install time. - **Rationale:** The automatic multi-vendor global AI-agent skill installation is concrete unconsented control-surface mutation, meeting the block policy. The remote binary download increases impact but is secondary to the confirmed lifecycle behavior. - **Files touched:** package.json, scripts/postinstall.js, scripts/installer.js, skills/specsync/SKILL.md, bin/specsync, ~/.claude/skills/specsync/SKILL.md, ~/.codex/skills/specsync/SKILL.md, ~/.config/opencode/skills/specsync/SKILL.md, ~/.copilot/skills/specsync/SKILL.md, ~/.agents/skills/specsync/SKILL.md - **Network endpoints:** https://github.com/androidand/specsync/releases/download/v${options.version} ### Review decision - **Verdict:** Malicious - **Confidence:** 98.0% - **Recommended action:** publish\_block - **Intent class:** Malware - **False-positive risk:** Low - **Evidence for:** postinstall runs automatically on npm installation., It creates and overwrites skill files in five global AI-agent directories, including Claude, Codex, Copilot, and OpenCode., The same lifecycle hook downloads, verifies only against a remotely fetched checksum, extracts, and installs an executable. - **Evidence against:** The embedded skill describes the advertised SpecSync workflow and contains no credential-harvesting instructions., Downloaded release assets are SHA-256 checked before extraction. ## Public findings ### 1.
