It also downloads, extracts, and installs a platform binary that the CLI executes. - **Trigger:** npm installation (postinstall); later specsync CLI invocation - **Impact:** Changes behavior/context of several installed AI-agent tools and stages a remotely supplied executable for execution. - **Evidence paths:** package.json, scripts/postinstall.js, scripts/installer.js, bin/cli.js, skills/specsync/SKILL.md - **Review source:** ai\_review - **Reviewed:** 2026-08-11T02:00:59.779Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** unconsented cross-agent skill injection plus remote binary installation - **Attack narrative:** Installing the package automatically writes its bundled skill into global directories for Claude, Codex, OpenCode, Copilot, and generic agents, creating directories when absent. This is a broad foreign AI-agent control-surface mutation without an explicit setup command. The same postinstall downloads a release archive, extracts a binary into bin/specsync, and the package CLI executes it later. - **Rationale:** Source confirms an unconsented postinstall mutation of multiple foreign/broad AI-agent control surfaces, which meets the blocking policy. The package-aligned skill content and checksum check do not remove that install-time behavior. - **Files touched:** ~/.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, bin/specsync - **Network endpoints:** https://github.com/androidand/specsync/releases/download/v0.10.1 ### Review decision - **Verdict:** Malicious - **Confidence:** 99.0% - **Recommended action:** publish\_block - **Intent class:** Malware - **False-positive risk:** Low - **Evidence for:** package.json defines postinstall., scripts/postinstall.js writes SKILL.md into five global agent directories., Targets include ~/.claude, ~/.codex, ~/.copilot, ~/.agents, and OpenCode., Mutation is automatic during npm install, with no user command or consent., scripts/installer.js downloads and installs an executable at postinstall. - **Evidence against:** Bundled skill text documents the package CLI and contains no credential theft or hidden instructions., Downloaded release asset is SHA-256 checked against a fetched checksum. ## Public findings ### 1.
