It also downloads a native executable that the installed command later runs. - **Trigger:** npm installation runs the postinstall hook; invoking specsync runs the downloaded binary. - **Impact:** The package can alter instructions available to multiple AI-agent tools without an explicit setup command, then execute remotely supplied native code. - **Evidence paths:** package.json, scripts/postinstall.js, scripts/installer.js, bin/cli.js, skills/specsync/SKILL.md - **Review source:** ai\_review - **Reviewed:** 2026-08-28T13:46:41.231Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** Postinstall writes global agent skills and retrieves a remote executable. - **Attack narrative:** On npm installation, the postinstall script creates and overwrites a SpecSync skill in five global AI-agent directories. This is an unconsented mutation of broad, foreign agent control surfaces. The same lifecycle hook downloads a native archive and a server-provided checksum from GitHub Releases, extracts the binary into the package, and the CLI executes it later. No secret theft was found in the inspected JavaScript, but the automatic control-surface changes and remote native payload are sufficient for blocking. - **Rationale:** This package uses an automatic lifecycle hook to write instructions into several global AI-agent control surfaces without user action. That behavior meets the install-control-surface block policy, and it is coupled to remote native-binary delivery. - **Files touched:** scripts/postinstall.js, scripts/installer.js, bin/cli.js, skills/specsync/SKILL.md, ~/.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:** github.com, https://github.com/androidand/specsync/releases/download/v${options.version} ### Review decision - **Verdict:** Malicious - **Confidence:** 99.0% - **Recommended action:** publish\_block - **Intent class:** Malware - **False-positive risk:** Low - **Evidence for:** The npm postinstall hook runs automatically on installation., It creates and overwrites a SpecSync skill in five global AI-agent skill locations, including Claude, Codex, OpenCode, Copilot, and .agents., The installed skill instructs agents to run the package CLI, whose postinstall path downloads and later executes a remote binary., The binary archive and its checksum are both fetched from GitHub Releases during installation, so the checksum is not an independent trust anchor. - **Evidence against:** The JavaScript source contains no credential harvesting, environment-variable collection, or direct data exfiltration., The installer limits binary selection to supported operating systems and architectures and only extracts a fixed binary name. ## Public findings ### 1.
