The copied set includes hook and session startup scripts, altering the agent's future runtime behavior without a separate setup command. - **Trigger:** Installing moflo through npm in a project that already has a .claude directory. - **Impact:** Package code gains install-time influence over Claude Code hooks and session startup in the consumer project. - **Evidence paths:** package.json, scripts/post-install-bootstrap.mjs, bin/lib/shipped-scripts.json - **Review source:** ai\_review - **Reviewed:** 2026-10-07T21:59:11.174Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** The postinstall bootstrap loads the package's shipped-script manifest and syncs listed files from the package into .claude/scripts, including hooks.mjs and session-start-launcher.mjs. - **Attack narrative:** The npm postinstall hook runs the bootstrap without requiring a separate setup command. When a consumer project already has .claude, the bootstrap copies package scripts there; the shipped list includes Claude Code hook and session startup files. This gives the package install-time control over the agent's future execution surface. - **Rationale:** Source inspection confirms an automatic npm postinstall writes package-controlled scripts into an existing consumer Claude Code control surface, including hooks and session startup. Under the install-control-surface policy, this unconsented mutation warrants blocking. - **Files touched:** .claude/scripts/ ### Review decision - **Verdict:** Malicious - **Confidence:** 93.0% - **Recommended action:** publish\_block - **Intent class:** Malware - **False-positive risk:** Low - **Evidence for policy risk:** package.json runs post-install-bootstrap.mjs automatically during npm postinstall., The bootstrap copies package scripts into the consumer project's .claude/scripts directory whenever that directory exists., The shipped script list includes hooks.mjs and session-start-launcher.mjs, extending the automatic write into Claude Code's hook and session startup surface., The integration targets contain workflow and memory helpers, guidance indexing, and hook behavior; these locations support the package's agent tooling purpose but do not establish consent to install-time writes., The npm postinstall command invokes post-install-bootstrap.mjs., The bootstrap syncs each manifest-listed script from the package's bin directory into the consumer's .claude/scripts directory., The shipped script manifest includes hooks.mjs and session-start-launcher.mjs. - **Evidence against:** The bootstrap skips when the consumer has no .claude directory and skips moflo's own source project., The notice script writes a restart reminder into .moflo and gates it on Claude session environment variables; it does not establish a separate attack. ## Affected versions and remediation This report applies to moflo@4.13.3. - Avoid installing moflo@4.13.3. 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.
