Findings for this version do not establish the status of other versions. AI assessment: suspicious; recommendation: downgrade to warn. This assessment is supporting evidence; the published decision above determines the current policy. LPM treats this as warn-only first-party agent extension lifecycle risk. Installing the package runs postinstall, which executes a bundled compiled binary and copies this product's Claude Code commands and related assets into the user's Claude and AI config directories. That is first-party agent extension setup, but it is automatic and the binary cannot be reviewed, so hook or settings writes beyond the package's own command files remain unresolved. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Recorded final verdict:** Suspicious - **Recorded analysis confidence:** 74.0% - **Started:** 2026-09-18T16:53:04.060Z - **Finished:** 2026-09-18T16:58:26.768Z - **Download time:** 1512 ms - **Static scan time:** 176 ms - **AI review time:** 321019 ms - **Total time:** 322708 ms The recorded confidence comes from the underlying analysis. Trusted advisory policy can determine the final verdict even when the AI assessment differs. ## Security analysis ### Published attack-surface review - **Summary:** Installing the package runs postinstall, which executes a bundled compiled binary and copies this product's Claude Code commands and related assets into the user's Claude and AI config directories. That is first-party agent extension setup, but it is automatic and the binary cannot be reviewed, so hook or settings writes beyond the package's own command files remain unresolved. - **Trigger:** npm install, via the postinstall script - **Impact:** The user's Claude Code command files and possibly hooks can change as soon as the package is installed, without a separate setup command. - **Evidence paths:** package.json, scripts/postinstall.js - **Review source:** ai\_review - **Reviewed:** 2026-09-18T16:58:26.768Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** install-time binary doctor run plus asset sync into Claude Code user config - **Rationale:** Readable source shows a Claude Code workspace tool that uses postinstall to install its own commands and run a bundled binary, which is first-party agent extension setup rather than proven theft or remote payload execution. Scanner malware labels track a prior version fingerprint and vendored tmux scripts; those are noisy without an inspectable attack chain. - **Files touched:** ~/.claude, ~/.ai, ~/.config/claudespace, libexec/claudespace.dist/claudespace-bin ### Review decision - **Verdict:** Suspicious - **Confidence:** 74.0% - **Recommended action:** downgrade\_to\_warn - **Intent class:** Dangerous Capability - **False-positive risk:** Medium - **Evidence for warning:** npm postinstall runs the bundled compiled binary as doctor --yes and then sync-assets with no extra user command., Asset sync is described and invoked as writing under ~/.claude, ~/.ai, and ~/.config/claudespace during install., Install is forced global because Claude Code hooks are invoked by bare command name on PATH., postinstall silently runs pipx uninstall claudespace to remove a prior install., The product registers a global Stop hook that, if left in place, runs on every Claude Code session on the machine., Core behavior lives in an opaque Nuitka binary that readable JS and shell shims only dispatch into. - **Evidence against:** Inspectable files match a documented Claude Code multi-pane workspace product, not a hidden dropper., tmux resurrect save.sh is vendored upstream plugin code, not a new payload., No self-dependency, eval, curl, or inspectable exfil sink was found in readable source., Slash-command files only load this package's own prompts from ~/.ai/prompts., Nested tarballs and the leftover .claude worktree look like published build leftovers, not an install-time unpacker. ## Affected versions and remediation This report applies to @ayorcodes/claudespace@1.0.4. - Review the evidence and your use of @ayorcodes/claudespace@1.0.4 before allowing it. Restrict the permissions described in this report. - Choose an independently verified alternative or release. This report does not establish that other versions are safe. ## Public findings ### 1.
