Mutates broad, foreign AI-agent control surfaces without an explicit user command; the installed CLI then executes a downloaded binary. - **Verdict:** Malicious - **Product-default install policy:** Block - **Firewall policy:** Warn by default - **Public report status:** Published - **Threat category:** Soft block: AI-agent control surface - **Selected version:** 0.12.0 - **Selected version is latest:** Yes - **Analysis source:** AI Security Review (lpm-firewall-ai) LPM flags this version as an AI-agent control-surface risk. On npm postinstall, the package creates and overwrites a SpecSync skill in global directories for Claude, Codex, OpenCode, Copilot, and generic agents. It also downloads a release binary that its CLI executes. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Verdict:** Malicious - **Confidence:** 99.0% - **Started:** 2026-08-19T12:38:56.503Z - **Finished:** 2026-08-19T12:39:39.533Z - **Download time:** 503 ms - **Static scan time:** 41 ms - **AI review time:** 42486 ms - **Total time:** 43030 ms ## Security analysis ### Published attack-surface review - **Summary:** On npm postinstall, the package creates and overwrites a SpecSync skill in global directories for Claude, Codex, OpenCode, Copilot, and generic agents. It also downloads a release binary that its CLI executes. - **Trigger:** npm installation (postinstall) - **Impact:** Mutates broad, foreign AI-agent control surfaces without an explicit user command; the installed CLI then executes a downloaded binary. - **Evidence paths:** package.json, scripts/postinstall.js, scripts/installer.js, bin/cli.js, skills/specsync/SKILL.md - **Review source:** ai\_review - **Reviewed:** 2026-08-19T12:39:39.533Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** unconsented cross-agent skill installation plus remote binary staging - **Attack narrative:** Installing the package runs postinstall automatically. That script creates per-user skill directories for several unrelated agent products and writes its bundled SKILL.md into each, even if those products were not involved in installation. The same hook downloads and stages a platform binary from GitHub Releases, which the package CLI later executes. This is an unconsented broad AI-agent control-surface mutation. - **Rationale:** The unguarded postinstall write to multiple foreign global AI-agent skill locations meets the firewall block criterion. The remote executable download increases impact but is not needed for the verdict. - **Files touched:** scripts/postinstall.js, scripts/installer.js, skills/specsync/SKILL.md, bin/specsync, bin/cli.js - **Network endpoints:** github.com ### Review decision - **Verdict:** Malicious - **Confidence:** 99.0% - **Recommended action:** publish\_block - **Intent class:** Malware - **False-positive risk:** Low - **Evidence for:** The postinstall hook unconditionally invokes installSkill()., Install-time code creates skill directories for five unrelated global AI-agent surfaces., It writes the bundled skill into each global agent directory without user action., Postinstall downloads a platform binary, extracts it, and the CLI executes it. - **Evidence against:** No source evidence of credential harvesting or data exfiltration., The bundled skill documents ordinary issue-sync workflows and dry-run guidance. ## Public findings ### 1.
