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 compiled binary that writes this third-party package's hooks and prompts into Claude Code's user directories. Those hooks are invoked by bare command name and are described as affecting every Claude Code session on the machine. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Recorded final verdict:** Malicious - **Recorded analysis confidence:** 88.0% - **Started:** 2026-09-18T17:14:37.513Z - **Finished:** 2026-09-18T17:18:41.082Z - **Download time:** 1026 ms - **Static scan time:** 144 ms - **AI review time:** 242398 ms - **Total time:** 243569 ms The recorded confidence comes from the underlying analysis.

Those hooks are invoked by bare command name and are described as affecting every Claude Code session on the machine. - **Trigger:** npm install of @ayorcodes/claudespace, which runs postinstall. - **Impact:** Claude Code sessions can run this package's global Stop and related hooks without a separate setup command. - **Evidence paths:** package.json, scripts/postinstall.js, README.md - **Review source:** ai\_review - **Reviewed:** 2026-09-18T17:18:41.082Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** install-time write of foreign Claude Code user hooks and assets - **Attack narrative:** On npm install, postinstall.js requires a global install, may uninstall a pipx copy of claudespace, then runs a bundled compiled binary to auto-confirm doctor setup and to sync assets. That sync writes this third-party package's prompts, hooks, and templates into Claude Code user directories. Those hooks are meant to run by bare command name on PATH, including a global Stop hook that fires on Claude Code sessions machine-wide, not only inside this product's panes. The user never runs a separate setup command; installing the package is enough. - **Rationale:** Postinstall automatically runs a compiled binary that writes this third-party package's hooks and prompts into Claude Code's user directories, a foreign machine-wide agent control surface. That is unconsented install-time mutation of a broad AI-agent control surface, 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 syncs prompts, hooks, and templates into ~/.claude, ~/.ai, and ~/.config/claudespace., The hook path requires a global install because Claude Code invokes those hooks by bare command name on PATH., Postinstall executes the bundled Nuitka binary as claudespace doctor --yes --no-launch and as sync-assets., Uninstall notes say a leftover global Stop hook fails on every turn of every Claude Code session on the machine. - **Evidence against:** Readable assets are role prompts and slash-command stubs for a Claude workspace CLI, not a hidden dropper., save.sh is a vendored tmux-resurrect snapshot with a pin file, which explains the scanner similarity hit., No outbound exfil URLs appear in readable source; the npm install string is an error message, not a nested install. ## Affected versions and remediation This report applies to @ayorcodes/claudespace@1.0.5. - Avoid installing @ayorcodes/claudespace@1.0.5. 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.
