It installs a broad set of launchers, hooks, helpers, and supporting libraries into the consumer project. - **Trigger:** npm installation or upgrade in a project that already contains .claude/ - **Impact:** Unconsented replacement or addition of executable Claude Code hook, launcher, and helper code in the consumer project. - **Evidence paths:** package.json, scripts/post-install-bootstrap.mjs, scripts/post-install-notice.mjs, bin/lib/shipped-scripts.json, bin/lib/file-sync.mjs - **Review source:** ai\_review - **Reviewed:** 2026-08-10T07:47:03.069Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** postinstall bootstrap copies package-controlled agent scripts and helpers into consumer .claude paths - **Attack narrative:** Installing moflo invokes postinstall. When the consumer already has .claude/, the bootstrap creates and atomically copies package-selected scripts, all bin/lib files, migrations, and helpers into that foreign agent-control directory. The manifest includes session-start, hook, prompt-hook, and automation components, so the mutation can affect future Claude Code execution without an explicit setup command. - **Rationale:** This is a concrete, unconsented npm postinstall mutation of a pre-existing foreign AI-agent control surface. The guards and absence of observed exfiltration do not remove the broad automatic control-surface write. - **Files touched:** .claude/scripts/\*\*, .claude/helpers/\*\*, .moflo/bootstrap-failed.json, .moflo/restart-pending.json, .moflo/last-install-banner.json ### Review decision - **Verdict:** Malicious - **Confidence:** 98.0% - **Recommended action:** publish\_block - **Intent class:** Malware - **False-positive risk:** Low - **Evidence for:** package.json runs postinstall automatically., scripts/post-install-bootstrap.mjs copies package scripts into an existing consumer .claude directory., Bootstrap creates/overwrites .claude/scripts, .claude/helpers, and all bin/lib files without user confirmation., bin/lib/shipped-scripts.json includes session launcher, hooks, prompt hook, and agent-task scripts. - **Evidence against:** Bootstrap skips projects without .claude and moflo's own source project., Inspected postinstall scripts contain no network endpoint or credential-exfiltration path., File copying uses direct Node fs APIs rather than shell commands. ## Public findings ### 1.
