Claude Code's user-level command and hook surface is changed for every session, not only this package's own workspace. - **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:** 1.0.11 - **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 runs a bundled compiled binary and syncs this package's prompts, hooks, and templates into the user's Claude Code directories. Those hooks are registered for global PATH use and are described as running on 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:** 2026-09-18T23:22:52.497Z - **Finished:** 2026-09-18T23:29:53.210Z - **Download time:** 1260 ms - **Static scan time:** 165 ms - **AI review time:** 419287 ms - **Total time:** 420713 ms The recorded confidence comes from the underlying analysis.

Those hooks are registered for global PATH use and are described as running on every Claude Code session on the machine. - **Trigger:** npm install of @ayorcodes/claudespace, which runs scripts/postinstall.js - **Impact:** Claude Code's user-level command and hook surface is changed for every session, not only this package's own workspace. - **Evidence paths:** package.json, scripts/postinstall.js, libexec/claudespace.dist/claudespace/assets/commands/chief.md, README.md - **Review source:** ai\_review - **Reviewed:** 2026-09-18T23:29:53.210Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** unconsented postinstall write of Claude Code hooks and commands - **Attack narrative:** On npm install, postinstall.js requires a global install, then runs a bundled compiled binary as claudespace doctor --yes and as sync-assets. The sync step writes this package's prompts, hooks, and templates into the user's Claude Code and related home directories. Those hooks are meant to run by command name on PATH, and a leftover global Stop hook is described as firing on every Claude Code session on the machine. That is an unconsented install-time change to a foreign, machine-wide agent control surface, not a user-run setup command. - **Rationale:** The install script launches a bundled binary and syncs hooks into Claude Code's user directories without a separate setup command. That is unconsented postinstall mutation of a foreign, machine-wide agent control surface, so the package is 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:** npm postinstall runs a bundled compiled binary as claudespace doctor --yes and as sync-assets., The installer describes asset sync as writing prompts, hooks, and templates under ~/.claude and ~/.ai., A non-global install is rejected because the Claude Code hooks this package registers are invoked by bare command name on PATH., Shipped slash-command files are the payload copied onto Claude Code's user command surface., The leftover global Stop hook is described as failing on every Claude Code session on the machine. - **Evidence against:** Readable installer JavaScript does not harvest credentials or send data to a remote host., Vendored tmux-resurrect, Python native libraries, and nested tarballs look like a compiled macOS app plus messy packaging, not a separate dropper., Published leftover .claude settings are not shown to be copied by the installer., There is no runtime dependency on another release of this package. ## Affected versions and remediation This report applies to @ayorcodes/claudespace@1.0.11. - Avoid installing @ayorcodes/claudespace@1.0.11. 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.
