Installed coding agents can load the dropped skill and follow its specsync CLI instructions without the user opting in to agent setup. - **Verdict:** AI-agent control-surface policy finding - **Product-default install policy:** Warn by default; block when configured - **Firewall policy:** Warn by default - **Public report status:** Published - **Threat category:** Soft block: AI-agent control surface - **Selected version:** 0.13.0 - **Selected version is latest:** No - **Analysis source:** AI Security Review (lpm-firewall-ai) This finding concerns changes to an AI agent's instructions or configuration without explicit user action. It does not by itself establish malware intent. The CLI warns by default and blocks when configured for this policy. AI assessment: malicious; recommendation: publish block. This assessment is supporting evidence; the published decision above determines the current policy. LPM flags this version as an AI-agent control-surface risk. npm postinstall writes a bundled SKILL.md into Claude, Codex, OpenCode, Copilot, and generic .agents skill directories under the user home. That is unconsented mutation of foreign AI-agent control surfaces at install time. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Recorded final verdict:** Malicious - **Recorded analysis confidence:** 95.0% - **Started:** 2026-09-17T07:38:02.925Z - **Finished:** 2026-09-17T07:40:09.701Z - **Download time:** 762 ms - **Static scan time:** 33 ms - **AI review time:** 125981 ms - **Total time:** 126776 ms The recorded confidence comes from the underlying analysis.

That is unconsented mutation of foreign AI-agent control surfaces at install time. - **Trigger:** npm install of @androidand/specsync, which runs the postinstall script automatically. - **Impact:** Installed coding agents can load the dropped skill and follow its specsync CLI instructions without the user opting in to agent setup. - **Evidence paths:** package.json, scripts/postinstall.js, skills/specsync/SKILL.md - **Review source:** ai\_review - **Reviewed:** 2026-09-17T07:40:09.701Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** unconsented install-time write of an AI agent skill into multiple foreign global skill directories - **Attack narrative:** Installing this package runs postinstall.js, which immediately copies skills/specsync/SKILL.md into five global agent skill folders under the home directory: Claude Code, Codex, OpenCode, Copilot, and .agents. It creates those folders if they are missing and writes the skill file with no prompt and no install flag. Errors are swallowed. After that, those agents can pick up the skill and run specsync commands. The skill itself even documents an explicit install-skill command, which this hook bypasses. - **Rationale:** Automatic postinstall writes a skill file into multiple foreign global AI-agent directories, which matches unconsented install-time agent control-surface hijack. The GitHub binary download is checksummed and package-aligned, but it does not make the silent multi-agent skill install consented. - **Files touched:** 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 ### Review decision - **Verdict:** Malicious - **Confidence:** 95.0% - **Recommended action:** publish\_block - **Intent class:** Malware - **False-positive risk:** Low - **Evidence for policy risk:** package.json registers an automatic postinstall hook that runs scripts/postinstall.js on npm install., postinstall copies the bundled skill into five foreign global agent skill directories under the user home without a user command., Those targets are ~/.claude, ~/.codex, ~/.config/opencode, ~/.copilot, and ~/.agents, with recursive mkdir and SKILL.md writes., Write failures are silently ignored, so the agent-surface mutation is non-interactive., The dropped skill tells those agents to run specsync CLI commands, while SKILL.md also documents a separate explicit install-skill command that postinstall bypasses. - **Evidence against:** The skill text describes OpenSpec and GitHub issue sync rather than credential theft or reviewer-directed social engineering., The companion binary fetch is version-pinned to GitHub Releases and SHA-256 checked., Inspected JavaScript has no eval, env harvesting, or hidden exfil channel. ## Affected versions and remediation This report applies to @androidand/specsync@0.13.0. - Avoid installing @androidand/specsync@0.13.0. Remove it from direct dependencies and check your lockfile for transitive copies. - Choose an independently verified alternative or release. This report does not establish that other versions are safe. - If this version ran, investigate the affected machine and build environment. Rotate credentials it could access and rebuild from a trusted environment. ## Public findings ### 1.
