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 runs a bundled binary that writes this package's Claude Code hooks and slash-commands into the user's global ~/.claude tree.

That hook is described as firing on every Claude Code session on the machine, not only inside a claudespace window. - **Trigger:** Installing the package with npm, which runs the postinstall script. - **Impact:** Every Claude Code session on the machine can pick up this package's Stop hook and commands without a separate setup command. - **Evidence paths:** package.json, scripts/postinstall.js, README.md - **Review source:** ai\_review - **Reviewed:** 2026-09-18T18:33:07.432Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** Install-time write of global Claude Code hooks and slash-commands - **Attack narrative:** On npm install, postinstall.js forces a global install, runs the bundled binary as claudespace doctor --yes --no-launch, and then runs sync-assets. That path writes this package's hooks and slash-commands under ~/.claude so a Stop hook can fire on every Claude Code turn on the machine. Skipping uninstall leaves that hook in place even after the commands are gone. The write happens during install, not only when the user later runs claudespace. - **Rationale:** npm postinstall executes an opaque bundled binary that writes Claude Code hooks and commands into the user's global ~/.claude surface without a separate setup command. That is unconsented mutation of a foreign, machine-wide AI-agent control plane, so the package should be blocked. - **Files touched:** scripts/postinstall.js, libexec/claudespace.dist/claudespace-bin, ~/.claude, ~/.ai, ~/.config/claudespace ### Review decision - **Verdict:** Malicious - **Confidence:** 88.0% - **Recommended action:** publish\_block - **Intent class:** Malware - **False-positive risk:** Low - **Evidence for policy risk:** package.json runs scripts/postinstall.js automatically on npm install., postinstall.js requires a global install because it registers Claude Code hooks, then runs the bundled binary as doctor --yes --no-launch and as sync-assets., postinstall comments say that sync writes hooks, prompts, and templates under ~/.claude, ~/.ai, and ~/.config/claudespace., README says a global Stop hook is left on every Claude Code session on the machine unless claudespace uninstall is run first. - **Evidence against:** Readable sources look like a real Claude Code workspace product, with role prompts and bin shims rather than a stub dropper., Vendored tmux-resurrect save.sh, the nested tarball, and the leftover .claude worktree are packaging noise, not a JavaScript downloader., No runtime self-dependency and no plaintext exfiltration URL in the inspected scripts. ## Affected versions and remediation This report applies to @ayorcodes/claudespace@1.0.7. - Avoid installing @ayorcodes/claudespace@1.0.7. 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.
