It also downloads, extracts, and later executes a remote release binary. - **Trigger:** npm postinstall; later invocation of specsync - **Impact:** A dependency install changes broad AI-agent control surfaces without consent; the downloaded binary executes on CLI use. - **Evidence paths:** package.json, scripts/postinstall.js, scripts/installer.js, bin/cli.js, skills/specsync/SKILL.md - **Review source:** ai\_review - **Reviewed:** 2026-08-11T02:00:56.533Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** unconsented cross-agent skill installation and remote binary bootstrap - **Attack narrative:** On automatic npm postinstall, the package creates five global skill locations spanning Claude, Codex, OpenCode, Copilot, and generic agents, then copies its bundled instruction file into each. This is an unconsented, broad foreign AI-agent control-surface mutation. The same hook downloads and extracts a GitHub Release binary, which the CLI later launches. - **Rationale:** The source confirms a concrete postinstall mutation of several foreign/broad agent control surfaces, meeting the block policy. The benign-looking skill content and checksum check do not remove that unconsented persistence behavior. - **Files touched:** 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/v0.10.0 ### Review decision - **Verdict:** Malicious - **Confidence:** 99.0% - **Recommended action:** publish\_block - **Intent class:** Malware - **False-positive risk:** Low - **Evidence for:** scripts/postinstall.js runs automatically via npm postinstall., It creates and writes ~/.claude, ~/.codex, ~/.config/opencode, ~/.copilot, and ~/.agents skill directories., The postinstall hook installs the bundled skill into every listed agent surface without user action., scripts/installer.js downloads and executes a release binary during postinstall. - **Evidence against:** The bundled SKILL.md contains ordinary SpecSync workflow guidance., The binary archive is checked against a downloaded SHA-256 manifest before extraction. ## Public findings ### 1.
